Most of the protagonists are members of the Occult Research Club at Kuoh Academy, which is a front for Rias Gremory's team of devils.[LN 1] They are involved in various devil activities from making contracts with humans to participating in Rating Games and other conflicts that involve the school.[LN 2] At the end of volume 4 of the light novels (and the second anime series), fallen angel leader Azazel becomes the club's adviser, and has the girls reside at Issei Hyodo's home.[LN 4][S2 ep 12] As of volume 10 of the light novels, most of the members move into Issei's residence, where other characters such as Orphis join the group.[LN 10]
Issei Hyodo (兵藤 一誠 Hyōdō Issei?)[a] is the viewpoint character of the light novels and the main protagonist in the manga and anime. Introduced as a second-year high school student at Kuoh Academy, he has a reputation of being a pervert, but Yuma Amano, the one girl who asks him out, ends up fatally stabbing him in the abdomen. After he is revived by Rias Gremory, he becomes a devil and her servant, where he joins the school's Occult Research Club. Ishibumi describes him as "a guy who loves girls and is really stupid".[LN 1 afterword]
Issei starts as a pawn for Rias,[S1 ep 3] but demonstrates great potential as his resurrection required Rias to consume all eight pawns of her allotted team.[S1 ep 5] Learning that he can assemble his own team in the future, he aspires to become a Harem King.[S1 ep 2] He tries to protect and help his friends,[S1 ep 3] some of whom fall in love with him, but while he enjoys their lustful affections, he hesitates to get serious with them because of the trauma suffered from the girl who stabbed him.[LN 10] Although he and Rias become a couple in a later storyline, the rest of the club girls continue to pursue him.[LN 10] In volume 12, his original body is destroyed, but Great Red and Orphis help him get a new dragon-based body. After he becomes a middle-rank devil,[LN 12] he acquires a familiar named Skithblathnir, which serves as a flying ship,[LN 13] and which develops into a flying harem palace called Ryuteimaru[b].[LN 14]
Issei's main item in combat is the Boosted Gear[c], a Sacred Gear which initially takes the form of a gauntlet on his left arm,[S1 ep 3] but as he trains and masters his powers, it spreads over his body. Rias reveals that the Gear is one of the Thirteen Longinus items;[S1 ep 5] as it houses Ddraig,[S1 ep 12] the Red Dragon Emperor.[S1 ep 9] His abilities with the Gear include: Boost enables him to double his powers every ten seconds;[S1 ep 4] Boosted Gear Gift[d] lets him amplify his ally's ability; [LN 5][S1 ep 11] and Dragon Shot[e] fires a beam against his enemies.[S1 ep 9] Some of his powers such as Juggernaut Drive consume Issei's lifespan.[LN 6] He can be promoted to use additional abilities associated with higher ranked pieces, either by reaching an opponent's headquarters during a Rating Game, or with the permission of the King.[S1 ep 11] After training with Dragon King Tannin, he is able to wear a full set of armor called the Balance Breaker Scale Mail.[LN 4][note 1][S1 ep 12] In volume 8 of the light novels, Ajuka Beelzebub upgrades his Gear so that he can use the Illegal Move Trident[f], which allows him to be promoted without the restrictions.[LN 8][LN 10] In volume 12, he combines with Great Red to assume the Super Gigantic Balance Breaker[g] form to defeat Jabberwocky.[LN 12] After Ddraig and Albion reconcile, he is able to use both dragons' powers, called Dividing Wyvern Fairy, without draining his life force.[LN 16]
Besides Boosted Gear, Issei invents some perverted techniques that he uses against his female opponents including: Dress Break[h] obliterates a girl's clothes after previously touching her;[S1 ep 10] and Bilingual[i] listens to her inner thoughts as if her breasts are talking.
Rias Gremory (リアス・グレモリー Riasu Guremorī?) is the main heroine of the series; she revives Issei after the latter was killed by Raynare.[LN 1 afterword] A third-year high school student at Kuoh, and their top idol, she is the leader of the Occult Research Club, which is a front for her devil team, of which she is the King.[S1 ep 3] Known as the Crimson-Haired Ruin Princess[j], she is heiress to the Gremory family of devils.[S1 ep 5] Although she is proud of being a Gremory heritage, she goes to a normal high school where she doesn't have to flaunt her status. Marchi, who wrote the English anime adaptation script, notes that Rias is a straightforward character who is not as sassy as the redheaded anime girls she sees in other shows. Rias develops feelings for Issei over the course of the series. She resigns her Rating Game match against Riser Phoenix when the latter threatens to kill Issei.[S1 ep 11] However, when Issei disrupts her engagement party and defeats Riser, she kisses him and moves into his household.[S1 ep 12] She does not mind being intimate with Issei,[S2 ep 1] but gets upset when he humiliates everyone with his lechery,[S2 ep 3] or when other girls want to steal him away.[S2 ep 7][S2 ep 8]
Asia Argento (アーシア・アルジェント Āshia Arujento?) is a nun with blonde hair who owns a set of Sacred Gear rings called Twilight Healing[k]. As the second main heroine of the series,[LN 1 afterword] she serves as the bishop on Rias's team. [S1 ep 4] Raised by the church, she attracts people seeking healing, however, after they discover that she can heal devils, she is considered a heretic.[S1 ep 4] When she moves to Issei's area, she befriends Issei, but is abducted by the fallen angels who steal her rings and kill her. Rias revives her to become a devil using her Bishop piece.[S1 ep 5] She moves into the Hyodo residence and transfers to their school.[S1 ep 6] Despite her devil identity, Asia tries to continue her faith, although whenever she prays or reads the Bible, she gets a severe headache.[S1 ep 6][S1 ep 9][note 2]
Asia is strongly attracted to Issei as her first friend; she is jealous whenever he acts perverted towards the other girls, asking that he redirect his actions towards her. She is willing to disrobe if that helps her become closer to him, which makes Issei conflicted between wanting to protect her innocence and indulging in her desires.[S1 ep 8][S2 ep 1][S2 ep 2]
Asia's familiar is a baby Sprite Dragon named Rassei[l][S1 ep 7] She later makes a pact with Dragon King Fafnir,after the latter broke his contract with Azazel, to become a Dragon User.[LN 14] Following Rias and Akeno's graduation, she becomes the new President of the Occult Research Club.[LN 18]
Akeno Himejima (姫島 朱乃 Himejima Akeno?) is the vice-president of the Occult Research Club; she wears her hair in a long black ponytail. Issei describes her as an ideal Japanese woman with a pretty face that is always smiling, and along with Rias, make up the two great big sisters that are idolized at the school.[ LN 1] She exhibits a gentle personality, but during combat, becomes highly sadistic.[S1 ep 3]. As Rias's queen, she possesses a variety of abilities, preferring elemental attacks[S1 ep 3] such as lightning strikes.[LN 3] She transforms her costume to that of a shrine priestess[S1 ep 4] and assumes the nickname Priestess of Thunder.[S1 ep 10]
In the second anime season, she helps draw off energy from Issei's Boosted Gear by sucking on his finger, and flirts more openly with him.[S2 ep 7] Akeno's back story is explored in volume 4, and she is revealed to be the daughter of the fallen angel leader Barkiel and a human shrine maiden.[S2 ep 6] After showing Issei her mixed wings, she is concerned he will hate her, but he accepts her, after which she acts more affectionately towards him, saying that she does not mind being third (after Rias and Asia).[LN 4] In volume 5 of the light novels, Issei convinces her to add her fallen angel aspects to her abilities, creating the Holy Lightning attack.[LN 5] She gets in a conflict with her father in volume 7 that causes her to act unstable and fragile, but Issei helps her reconcile with him.[LN 7]
Over the course of the light novels, Akeno continues to progress her abilities. She acquires Fallen Angel Mode (堕天使モード Datenshi Mōdo?), which increases her Holy Lightning abilities, and passes the promotion exam for the middle-class devil rank.[LN 12] In a later volume, she creates Raikouryuu, a Eastern dragon made of Holy Lightning.[LN 14]
Koneko Toujou (塔城 小猫 Tōjō Koneko?) is a first-year student whom Issei describes as petite with a loli-face, a mascot character admired by both boys and girls.[S1 ep 2] Her position in Rias's group is the rook, where she withstands crushing forces and can throw heavy objects with little effort.[S1 ep 3] Although she is quiet and cool-headed, rarely showing emotion, she is often irritated with Issei perverted tactics.[LN 5]
Originally named Shirone (白音?), Koneko is a two-tailed cat demon. When she is sentenced to death for her sister's crime of killing her master, she is saved by Sir Zechs, who in turn, gives her to Rias, who gives her the Koneko ("kitten") moniker.[LN 5] Her familiar is a small white cat named Shiro (シロ?).[S1 ep 7] Ishibumi notes that he discussed Koneko's identity with his editor but it wasn't fleshed out for over a year until Volume 5.[LN 5 afterword]
Yuto Kiba (木場 祐斗 Kiba Yūto?) is a second-year student and the school's top prince.[LN 1]. He serves as the knight on Rias's team.[S1 ep 3] His Sacred Gear, Sword Birth[m], lets him generate swords with various properties for their blades, such as Holy Eraser (a blade that devours light) or Flame Delete (an ice blade that negates fire attacks). He can also generate a large number of blades from the ground to pierce enemies or give him more options in combat.[S1 ep 11] Ishibumi created Yuto to add appeal to the female readers of his series, [LN 4 afterword] and has him develop as the ace of the team as well as a strong backing character for Issei.[LN 5 afterword]
Yuto is the sole child survivor of the Holy Sword Project, which tries to develop children that can wield the Holy Swords that can destroy devils. He nearly dies from escaping the destruction of the children, but is saved by Rias, and becomes her servant.[S2 ep 2] Hoping to avenge the death of his comrades, he seeks to destroy the Holy Sword Excalibur's remnants.[S2 ep 3] During his battle against Kokabiel and Freed Sellzen, he receives a crystal that contains the souls of his comrades from the project's leader Valper Galilei, and uses it to make his ultimate Balance Breaker sword form called Sword of Betrayer[n], which has both Holy and Demonic attributes.[S2 ep 5]
Ishibumi purposely gave light novel volume 3 a boy's love-themed title as that story focused mainly on Yuto.[LN 3 afterword] Following the battle, he acts more friendly towards Issei, although some of his statements make Issei uncomfortable.[S2 ep 7] Yuto's familiar is a small bird, but Issei refuses to express further interest in the topic.[S1 ep 7]
In volume 12, Yuto defeats Siegfried after the latter's demonic sword Gram accepts him as his new master. Other demonic swords choose Yuto, and he is also officially promoted to the middle-class devil rank.[LN 12] However, in volume 17, he has difficulty controlling Gram.[LN 17]. Following Akeno's graduation, he becomes Vice-President of the Occult Research Club.[LN 18]
Xenovia (ゼノヴィア Zenovia?) is a Church follower who, along with Irina Shido, are sent to retrieve or destroy the stolen Excalibur swords. Ishibumi describes her as "a troublesome girl because she does things she doesn't understand herself which she regrets afterwards." and that Issei calls her a girl who you can’t “grasp a hold of”.[LN 3 afterword] In the anime, she has short blue hair.[S2 ep 2][S2 ep 3]
Xenovia's initial weapon is the Holy Sword Excalibur Destruction[o]; however, during the battle against Kokabiel, she brings out the Holy Sword Durandal, which she states is on par with Excalibur and is able to cut through anything. It is revealed that she is a natural Holy Sword user, that is, she possesses the genes that enable her to wield a Holy Sword instead of having them implanted as with Freed and Irina.[S2 ep 5] After learning that the God of her Church no longer exists, Xenovia becomes a devil for Rias's team as a knight, and joins the school in Issei's year.[S2 ep 6] She seduces Issei by telling him she wants to make a baby with him because they both have strong genetics.[S2 ep 7] After moving into the Hyodo residence,[LN 4] she shares a close relationship with Asia, and reconciles with her for her misdeeds.
In volume 9, she has her Durandal sword fused with some of the Excalibur fragments to create Ex-Durandal, which is able to transform into one of the seven Excaliburs.[LN 9] Although Cao Cao shatters Ex-Durandal in volume 11, she has it repaired with the final Excalibur fragment from Arthur Pendragon in volume 12.[LN 12] and masters the powers of six of the seven Excaliburs.[LN 14]. Following Sona's graduation, she expresses a desire to become the high school's next student council president.[LN 17]
Irina Shido (紫藤 イリナ Shidō Irina?) is a Church follower and Issei's childhood friend. Ishibumi developed her as a character that represented someone on the Heaven/Church side of the three factions.[LN 3 afterword] She was a tomboy who has since styled her hair into twintails. She bears the Holy Sword Excalibur Mimic[p], which transforms itself into any shape its user desires. Although she is saddened that Issei has become a devil, she still has feelings for him.[S2 ep 2][S2 ep 3] In the storyline involving the Grigori, Irina is defeated by Freed Sellzen, and her Excalibur Mimic is taken.[S2 ep 4] She is sent to the Church headquarters to recover,[S2 ep 6] and returns as a representative of the Church to support Michael at the summit.[LN 4] She reappears in Volume 6 where she joins Xenovia and Asia as a group which Issei calls the "Church Trio" (教会トリオ Kyōkai Torio?).[LN 6 afterword]
Like Xenovia, she sometimes shows a lack of common sense: in one early instance, she spends her and Xenovia's money on a fake painting of a saint, and ends up having to beg for food.[LN 3] In another instance, when Xenovia and Asia are seducing Issei; she proclaims that it is too dirty, but clarifies that she meant the location rather than the act itself.[volume & issue needed] Regardless, she is attracted to Issei and is concerned whether having Issei's babies will put her at risk of being a fallen angel.[volume & issue needed]
As of volume 6, she becomes an angel with the Ace ranking, which allows her to throw spears of light. She also moves into Issei's residence.[LN 6] In Volume 17, she gains a second pair of wings,[LN 17] and later obtains her own Holy Sword, Hauteclere.[LN 18]
Gasper Bloody (ギャスパー・ヴラディ Gyasupā Vuradi?, alt. Gasper Vladi) is a cross-dressing dhamphir, a half-vampire boy who is a bishop on Rias's team.[LN 4].[LN 4] His Sacred Gear, Forbidden Balor View[q], lets him freeze time whatever is in his field of vision, but because he is unable to control it, he is sealed in a remote room in the school, and acts as a shut-in.[S2 ep 9] Ishibumi notes that Gasper's being a cross-dressing, vampire, shut-in gave him a lot of material to work with.[LN 4 afterword]
As a child of a Vampire Lord and a human woman, Gasper was shunned by the Vampires, including those in his clan.[S2 ep 9] Combined with his shyness and Sacred Gear, he tends to hide a lot and not make friends.[S2 ep 9] After the club rescues him from the clutches of Cattleya Leviathan, he becomes more open to attending school, although he sometimes hides his face under a paper bag or hides in a cardboard box. He is able to control his power better after drinking Issei's blood.[LN 4]
In Volume 12 when he heard about Issei's death from Georg, who mocked Issei's sacrifice, this caused Gasper to undergo a change where he created an enormous amount of darkness that literally devoured everything (even the mist created by Dimension Lost, although where anything devoured "went" is unknown), which allows him to defeat Georg. This shadows are capable of turning into grotesque parodies of creatures.[LN 12] The fear of this power was the main reason he was bullied and cast out by his clan, his mixed heritage and Forbidden Balor View were just additional, but more minor, public reasons.
In Volume 16, Gasper returns to his birthplace to meet up with Rias and Yuuto who were confined in the Tepes Castle. He was then reunited with his childhood friend, Valerie, who became the new "King" of the Tepes Clan, but was greatly saddened to see her mentally broken due to overusing the Longinus, Sephiroth Graal, caused by Marius Tepes. Angered and disgusted by Marius and the Vampires that made use of Valerie, Gasper's hidden power awakens and he killed Marius and the Vampires that supported him. It is revealed that he was born with a fragment of the consciousness of the original god Balor, and created a different aspect of him, called Forbidden Invade Balor the Beast. Its power is so great that has the potential to become the 14th Longinus. [LN 16]

Azazel (アザゼル Azazeru?) is the Governor-General of the fallen angels. He is interested in the Sacred Gears and collects a vast number of them to study.[S2 ep 4] In the anime series, he introduces himself as a regular patron of Issei, asking him to accompany him for drinks or to play video games. However, he formally introduces himself halfway into the second anime series.[S2 ep 6] He becomes the club's advisor and a teacher at Kuoh.[LN 4] Ishibumi created Azazel with the role of a coach, so that he does not participate in Rating Games, and also, along with Yuto Kiba, appeal to the female readers of his series. He also uses him as a "strong and cool explanation character." [LN 4 afterword].
According to Sir Zechs Lucier, Azazel dislikes fighting, which was the reason why the Fallen Angels were the first to retreat from the war. He is very laid back and relaxed, H met up with the leaders of the Devils and Angels in Volume 4 of the novels to form a truce. He lost his left arm to Katerea Leviathan when they fought, as Katerea made indestructible tentacles that wrapped Azazel's left hand, claiming that they will explode; Azazel nonchalantly cuts off his own left hand, which he soon replaces with a prosthetic arm made from his Sacred Gear research. Azazel has a self-made artificial Sacred Gear that is used to seal Fafnir, the Golden Dragon and one of the five Dragon Kings.
Azazel's artificial Sacred Gear, Down Fall Dragon Spear[r], takes the form of a jewel, as its core and its exterior are fragile, and forcefully activates its Balance Breaker, the Down Fall Dragon Another Armor[s], which creates a Golden Dragon Armor that is similar to Issei and Vali's Scale Mail. He also has a second artficial Sacred Gear called the Blazer Shining Aura Darkness Blade[t].
In Volume 12, Azazel resigns from his post as Governor-General of the Fallen Angels, which is now succeeded by Shemhazai, and became Grigori's Advisor of Special Technology and supervisor for Issei's town.[LN 12]
Rossweisse (ロスヴァイセ Rosuvaise?) is a Valkyrie who excels in Norse magic, first appearing in Volume 5 of the light novels. Originally Odin's bodyguard, she is the one who always stop him from doing dirty things; however in retaliation, Odin always tease her for being a Valkyrie that has no boyfriend. After the battle with Loki and Fenrir, Odin leaves her in Issei's town and later gets persuaded by Rias to become her servant, her ranking being "Rook" alongside Koneko, and remains in Kuoh Academy as a teacher. Although the obvious reason Odin left her is to get away from her, but considering Rias had all the materials at hand for her enlistment pitch, its possible he discussed the matter with Rias under the table and wanted to remove any possible objections Rossweisse might use to say no. After all, he mentioned due to the decrease in heroes that fewer and fewer Valkyries were needed or sought. With Rossweisse in the group she gets better pay, is representing the Norse in a popular and rising group, and likely (albeit unknowingly) is being used as the Norse representative Odin mentioned sending over to exchange cultures, not to mention Odin can now hire a new, inexperienced Valkyrie to attend him without having to leave Rossweisse to the wolves.
Unlike most of the female characters who already have a crush on Issei, she is still figuring out if she likes him or not. She is extremely bitter on the fact that she does not have a boyfriend, and gets angry when she is made fun of that. Odin uses this several times to knock the wind out of her when she is protesting or interfering with him doing something vulgar. She has a tendency to buy things at sales when they're cheap, allowing Issei to coin for her the nickname "The 100-Yen Shop Valkyrie" (100均ヴァルキリー?). This also shows during the Kyoto trip when Issei used dress break on her so he could peep on the female students in the hot springs by her getting mad and lecturing him about destroying her clothes before getting embarrassed about being naked. She moves into the Hyodo Residence in Volume 8. She left to train with a Norse mage she knows in Volume 11 and returns in Volume 12 after learning new, powerful defensive spells along with how to combine them with the defensive traits of Rook. Thus, gaining enough power to defend against Balance Breakers and even the equivalent of 10x the damage that Heracles' Balance Breaker can create.
In Volume 14 both the Gremory and Sitri groups are surprised to hear her speak in an unpolished, country voice while talking to her grandmother in her homeland. Also, its noted that part of the reason she is so concerned about money is that she has been sending money over to her grandmother, to help out since the area her hometown is in is described as having nothing and essentially barren. She is currently pursuing two goals, the first is to create a school to teach devils how to become Valkyries, and the second is to open a discount store that carries everything in her homeland. In Volume 17 she asks Issei to pretend to be her boyfriend to convince her grandmother Göndul that she is safe in her new life as a devil and as teacher.

Ravel Phoenix (レイヴェル・フェニックス Reiveru Fenikkusu?) is the younger sister of Riser Phoenix and a former member of his team.[S1 ep 11] First appearing in Volume 2 of the light novels, she is a Bishop who has yet to reveal her true powers.[LN 2] She follows her brother's authority to a full degree, as she sees that there is no one who can defeat him. Just like her brother, Ravel is also a Phoenix. After seeing her brother's defeat at the hands of Issei, she becomes infatuated with him (albeit with tsundere tendencies), and later transfers to his school so she can spend more time with him.[volume & issue needed] Ishibumi notes that Ravel had become popular with the readers in volume 6 that he was considering making her a main character.[LN 6 afterword]
Before knowing Issei, when Ravel was young she has great admiration towards hero stories told by her butler. She always dreams of becoming a woman who can become a support for her ideal hero till she slowly forgets her dreams without realizing as she gradually grows older. During Riser's engagement party, seeing Issei fighting for the sake of the woman he loves, Ravel's dream naturally came back to her along with curiosity to understand everything about him.
Later on as the story continues, she falls in love with him completely, and does not mind becoming his concubine so long as she can be with him. She is currently a "free" Bishop since she traded herself to her mother's team (who does not participate in Rating Games) for one of her mother's unused Bishop pieces. It is likely she will trade herself to become one of Issei's Bishops when he gains peerage, as she wants to be of use to Issei. She moves into the Hyodo Residence in Volume 10 and enrolls in Kuoh Academy as a first-year student, alongside Koneko and Gasper. She is in Koneko's class at school and despite the two of them bickering often (paying homage to the vitriolic relationship between cats and birds, given their species), they are very close friends. Currently, she is one of Issei's managers (alongside Grayfia) and had been tutoring him so he could pass the written part of the exam to become a Middle-Class Devil. During the events of Volume 12, the Phoenix family indicates that not only are they going to allow her to "stay" at Issei's house to "attend school", but are hoping an intimate relationship forms between him and her for various reasons.
Orphis (オーフィス Ōfisu?), known as Ouroboros Dragon[u] and the Infinite Dragon God[v], is a dragon that is said to be more powerful than God and the devil kings.[S2 ep 12] She founds the Chaos Brigade with the hopes of getting rid of Great Red from the Dimensional Gap. However, she was betrayed by Cao Cao who stole her power under the intention of creating another Orphis, rendering her in a presumed powerless state. Cao Cao, however, underestimated her, as she has released her powers in forms of snakes before Cao Cao came to steal her powers. As such, she did not lose most of her powers. Like Great Red, Orphis does not like to interfere in the matters of the world, having interest only in Great Red. As such, she is more of a figurehead than a leader of the Chaos Brigade, and any plans or acts not pertaining to Great Red were by the will of the members, not hers.
In Volume 12, she is rescued by Great Red and helped him in restoring Issei's body. The two seem interested in Issei, and both were saying "Zoom Zoom Iyaaan" after the battle with the Jabberwocky to Issei and Ddraig's dismay. Although she does not say it, she is probably very fond of Issei, as he is her first friend and had offered her a home in his house in Volume 11. This is a big deal as she had helped protect Asia and Irina later in the volume simply because they had tea and played cards together. According to Issei, Orphis is not evil, just naïve and did not mind being used by the Chaos Brigade, as they had promised to kill Great Red for her. Currently, the faction heads have used numerous seals to hide her presence. This is to avoid upsetting members of their factions and hide her from the remaining members of the Chaos Brigade. Even with the power stolen from her, they are aware that she is too powerful to control, but are allowing her to stay with Issei to encourage the interest she seems to be showing for him. She later moves into the Hyodo Residence at the end of Volume 12 to continue "observing" Issei, saying she has a vested interest in him as a part of her was used to recreate Issei's body with Great Red's flesh. Currently, she seems to be welcoming the feeling of having an actual home and friends, even to the point of not attempting to do any significant damage to Great Red other than kicking him during the time she and Issei were riding his back.
Devils (悪魔 Akuma?) represent one of the three major supernatural groups (the others being the fallen angels and the angels in a three-way struggle over the control of the world). Because of the great war hundreds of years ago, the devils have become few in number, so they have organized themselves by a feudal system in which the higher-ranked devils lead a small group of up to 15 servants, each of whom is designated by a piece in the game of chess, and has enormous powers. The servants are lower-ranked devils, some of whom are made from humans. However, if a devil were to free themselves from their master they are known as a stray devil and are to be executed.[LN 1] The devils overall are lead by the Four Great Devils (四大魔王 Yondai MaŌ?, also Four Devil Kings), who are titled by devil names from folklore.[LN 3]

Sona Sitri (ソーナ・シトリー Sōna Shitorī?), known as Sona Shitori (支取 蒼那 Shitori Sōna?) in school, is the glass-wearing student council president and the third most popular girl behind Rias and Akeno. As a devil of the Sitri family, she is Rias's childhood friend and rival.[S1 ep 7] Her Evil Pieces initially consist of girls, except for Genshiro Saji, who is the only male. She specializes in using water-based magic, which is accentuated when near large bodies of water. In Rating Games, she uses a "technique" strategy which is effective against the power-type strategies employed by Rias.[LN 14] Following her graduation, she realizes her dream of opening Aurea Academy, a Rating Games school for devils regardless of their rank and status. However, the school is attacked by the Hexennacht during an open house event.[LN 17]
Sona's Evil Pieces include council members Tsubaki Shinra (queen) and Genshiro Saji (pawn). She also has: Tsubasa Yura[w] (rook); Tomoe Meguri[x] (knight); Momo Hanakai[y] (bishop); Reya Kusaka[z] (bishop); Ruruko Nimura[aa]; Loup Garou[ab] (rook), who is a werewolf magician; and Bennia[ac] (knight), who is half-Grim Reaper.[LN 14]

- Voiced by: Yūichi Iguchi (Japanese), Kyle Phillips (English)
- The Student Council Secretary and Sona's Pawn who became a Devil through the use of four Pawn pieces used by the latter.[ S1 ep 7] He is in love with Souna, expressing a desire to sleep with her and "accidentally" impregnate her so that they would get married. He is very supportive of Sona's dreams, stating that her dreams are his dreams. So much so that in the Rating Game with the Occult Research Club, he tapped into his life force to power up his abilities and inflict serious damage on Issei before losing their one-on-one duel, but gaining recognition from the VIPs watching the Game. He plans on helping fulfill Sona's dream by becoming a teacher. However, he is extremely jealous of Issei's relationship with his master, Rias, being called by name by Sona, and having ecchi encounters with beautiful girls while he (Saji) is not even registering on Sona's radar as a potential boyfriend.
- He is in possession of a Sacred Gear called Absorption Line[ad],[S2 ep 4] which holds the soul of Vritra, the Black Dragon and one of the Five Dragon Kings. One of Absorption Line's abilities is to fire a rope to grab someone.[S2 ep 4] Originally it was split up into four individual pieces with him only having a portion of it, but eventually Azazel gathers all the pieces and combines them together for Saji. His three remaining Sacred Gears are "Blaze Black Flare" (邪龍の黒炎（ブレイズ・ブラック・フレア） Bureizu Burakku Furea?, lit. "Evil Dragon's Black Flame"), "Delete Field" (漆黒の領域（デリート・フィールド） Derīto Fīrudo?, lit. "Domain of Darkness"), and "Shadow Prison" (龍の牢獄（シャドウ・プリズン） Shadō Purizun?, lit. "Dragon Prison"). Saji is far from being able to control the power of Vritra, and would usually go out of control when used extensively. In Volume 7, it is revealed that Saji can enter into a Dragon King form called "Vritra Promotion" (龍王変化（ヴリトラ・プロモーション） Vuritora Promōshon?, lit. "Dragon King Transformation"). However, while he does start conversing with Vritra like Issei talks with Ddraig, he can only handle so much power for so long without going berserk. Also, Vritra says Saji will go berserk if Issei uses Boost and Transfer to increase Saji's power. Fortunately for him, he is willing and able to endure grueling training and hardship to get stronger as he wants to surpass his friend, rival, and fellow Pawn Issei. In Volume 17, he finally reaches the power of the Balance Breaker, called Malebolge Vritra Promotion, to defend the school Sona built from the Hexennacht forces.
Introduced as Rias' fiancé, Riser Phoenix (ライザー・フェニックス Raizā Fenikkusu?) is a high-ranking devil and the third son of the Phoenix family.[S1 ep 8] He wishes to marry Rias to preserve a full-blooded devil lineage, although he enrages Issei when he shamelessly fondles his queen piece Yubelluna[ae].[S1 ep 8] Rias notes that he can regenerate quickly like the creature of the same name, and has a strong record in the Rating Games; his losses so far have been on purpose to allies.[S1 ep 9] Riser's Evil Pieces consist of 15 girls, which makes Issei envious.[S1 ep 8] In addition to "Bomb Queen" Yubelluna, who uses explosive fire magic, there are: Riser's sister Ravel (bishop); Karlamine[af] (knight), a sword maniac who uses fire and wind attacks; Siris[ag] (knight), who wields a giant broadsword that sends shock waves; Isabela[ah] (rook), who wears a mask covering half of her face;[LN 5][S1 ep 11] Shueran[ai] (rook), who uses Chinese Kung Fu and emits flames from her hands and legs;[S1 ep 10] and Mihae[aj] (bishop). Riser's pawns include: Mira; Ile and Nel, twin sisters who wield chainsaws; Ni and Li, twin catgirls; Shulyer; Marion; and Byurent.[S1 ep 10]
Although he defeats Rias in the Rating Game, he is challenged by Issei at his engagement party with Rias, and loses when Issei uses Balance Breaker Scale Mail to attack his mind (the one thing he cannot easily regenerate).[S1 ep 12]. Afterwards, he falls into a slump and develops a fear of dragons.[volume & issue needed] He recovers from his slump in Volume 10 of the light novels, giving advice to Rias on Rating Games and warning Issei that should he mistreat his sister Ravel, he will burn him to a crisp.[LN 10] He reappears in Volume 12 alongside his brother to cheer up his sister and the Gremory Team before leaving to fight alongside his brother.[LN 12]
Sir Zechs Lucifer
- Voiced by: Junichi Suwabe (Japanese), Alex Organ (English)
- Sir Zechs Lucifer (サーゼクス・ルシファー Sāzekusu Rushifā?, alt. Sirzechs Lucifer), nicknamed the Crimson Satan (紅髪の魔王（クリムゾン・サタン） Kurimuzon Satan?) is the most powerful of the Great Devils, more so than the previous Lucifer. He is the older brother of Rias.[S1 ep 10]
- He is a wizard-technique type where he uses his Power of Destruction in forms of several orbs that he can control at will. When he focuses and concentrates strongly he can use a move he calls Ruin the Extinct[ak] which only destroys his target. This is shown once when he had a sphere enter Creuserey's mouth and destroy the snake that was in his stomach, without causing any damage to Creuserey himself. As stated by Azazel, the reason why he was chosen as a devil king due to his overwhelming ability to nullify magic. However, Milicas comments during his visit to the Gremory Household that Grayfia is the strongest member of the Lucifer team (most likely because he doesn't know about Sir Zechs's "other" form.)
- In Volume 12, he goes into the front lines to protect the Underworld, where he revealed his "true form" in which he converts himself into the Power of Destruction called the Human-Shaped Aura of Destruction[al] that destroys everything regardless of his will. According to Azazel, he compresses his demonic powers to the size of a human shape, and has demonic powers that are ten times more powerful than the original Lucifer. His father also mentions to Azazel that he is a Super Devil and a mutation of a Devil, possibly so different that it might be a mistake to even call him a Devil. Because of this, being a devil king was the only role for him.
- He is Grayfia's husband and father of their son, Milicas Gremory.
- Sir Zechs's Evil Pieces include: Enku[am] (pawn), a Chinese Qilin who escorts Grayfia and brings luck to the Hyodo residence;[LN 8]Souji Okita[an] (knight), a reincarnation of Okita Souji who is Yuto's swordsmaster and moves at God-like speeds;[LN 12] Surtr Second[ao] (rook) a clone of Surtr that went berserk and the Norse Gods abandoned him; Bahamut[ap] (rook) who helps transports his group but can also annihilate grunts; MacGregor Mathers (bishop), a master magician; and Beowulf[aq] (pawn), a descendant of the original Beowulf who is said to be among the top five pawns in the Underworld.
- Grayfia Lucifuge (グレイフィア・ルキフグス Gureifia Rukifugusu?)
- Voiced by: Saori Seto (Japanese), Krishna Smitha (English)
- Grayfia is Sirzerchs's wife and serves as the Queen in his group as well as a maid in the Gremory household.[S1 ep 8] She is the mother of Milicas Gremory. Grayfia comes from the House of Lucifuge, a family of pure-blooded Devils from the Extra Demons whose family served under the original Lucifer. She is a Devil on par with the Four Maous, and is known as the "Strongest Queen". She once challenged Serafall for the spot of Leviathan. She is nicknamed the Silver-Haired Queen of Devourer[ar] and uses ice-based magic. For some reason, she does not appreciate having family titles or ties to the Gremory family mentioned while a maid. As a maid, she always acts in a cold, calm, and professional manner with extremely rare instances of emotions showing in her face or voice. This is because when she is a maid she wants to do it completely, which has resulted in her having a relationship with the Gremory family as a maid. One of the few instances she showed emotion was in Volume 2 during her conversation with Issei just before she gave him the magic circle to crash Riser's engagement party and release a griffin to ride home on. She acts and expects to be treated with the difference between a noble and servant, although she still reserves the right to chastise Sirzechs and Millicas if they act improper or acknowledge her as part of the family and not a maid or Sirzech's Queen. She enjoys doing small tasks and housework and it seems easier to move around doing simple matters as a maid than the wife of a devil king. This may be her solution to the similar issue Sona had of wanting to help Rias with things (like Akeno's and Koneko's difficulties accepting their Fallen Angel and Nekomata heritages) but unable to do so due to restrictions of being a proper, high-class, and noble Devil.
- Every now and then, she will take a day off as a maid and become a high-class lady who is to be acknowledged as a noble lady of the Gremory Family, Sirzech's wife and Rias' older sister. While maintaining the proper demeanor of a noble lady, she does allow emotions to show on her face and is less reserved around others. So far, she has only been seen to take a day off once in the Extra Life chapter of Volume 8 in the light novels. During that chapter, she acted more friendly with everyone and even showed embarrassment over Akeno saying her (Grayfia's) romance with Sirzechs is a legend among young, female devils and Koneko mentioning their courtship had been made into a play.
- Voiced by: Ai Shimizu
- Serafall Leviathan (セラフォルー・レヴィアタン Seraforū Revaiatan?) is Sona's older sister and one of the Four Great Devils.[S2 ep 5] She is introduced as a cosplayer with a magical girl dress who visits during the school's open house.[S2 ep 8] This prompts Issei to coin her the nickname "Maou Shoujo" (魔王少女 MaŌ Shōjo?, lit. "Satan Girl"). She has a deep sister complex, going as far as threatening to attack Heaven for not being informed of the school's open house by her little sister. Adding to her childlike personality, she calls Sona "So-tan" (ソーたん Sō-tan?) and Sirzechs (and everyone else) "Sirzechs-chan". She is the devil king in charge of foreign affairs (other factions). Coming from the Sitri Clan, Serafall is highly skilled in water-based magic while specializing in ice-based magic, and has an attack called "Celsius Cross Trigger" ((零と雫の霧雪(セルシウス・クロス・トリガー) Serushiusu Kurosu Torigā?). Despite the childlike attitude she definitely has the power to hold the position of devil king since she was able to take out a Bandersnatch all by herself. She also has her own show called "Levi-tan" in competition with the Oppai Dragon show based on Issei.
Tsubaki Shinra (真羅 椿姫 Shinra Tsubaki?)
- Voiced by: Akiko Kimura (Japanese), Lauren Allison (English)
- The Vice-President of the Student Council and Souna's Queen[S1 ep 7]. Her relationship with Souna is similar to that of Rias and Akeno. She is the fourth most popular girl in the school, and also wears glasses. She is a master swordsman who faced against both Yuto and Xenovia on separate occasions during their Rating Game. While she manages to defeat Xenovia, she failed to gain the upper hand against Yuto by sword skills alone. Her Sacred Gear, Mirror Alice (追憶の鏡（ミラー・アリス） Mirā Arisu?, lit. "Mirror of Recollection"), reflects double damage but cannot be summoned twice in a row without a cooldown period. After losing to Yuto at the Rating Game between their masters, she develops a huge crush on him. Also like him, she seems to prefer fighting with just swords and her Sacred Gear while leaving magic attacks to her group's King and Bishops. Her magic level should be higher than average as her group's Queen.
- Sairaorg Bael (サイラオーグ・バアル Sairaōgu Bāru?)
- Sairaorg Bael is the next heir of Bael Family and Rias' cousin. Unlike Rias and Sirzechs, Sairaorg did not inherit the Power of Destruction from his lineage. Because of this, his younger brother was the one who had been chosen to become the heir of the Bael Family. Misla encourages him to become stronger in other ways, which resulted in him training his body with martial arts, pushing himself to his utmost limits to become powerful. With this strength, he defeated his younger brother, restoring his position as the next heir. Sairoarg desires to become one of the four Maous to prove himself, as well as to prevent others from feeling the same pain he felt.
- Appearing in Volume 5 during the Young Devils Gathering, he fought against Zephyrdor Glasya-Labolas in a Rating Game which he and his team won with little effort. He faced Rias in a Rating Game in Volume 10, defeating Yuto, Xenovia and Rossweisse before he and his Pawn, Regulus, faced off against Rias and Issei. Sairaorg overwhelms Issei, until the latter achieved his Cardinal Crimson Promotion, where both engaged in a relentless fist fight. He later fought against Heracles in Volume 12 and easily defeated the giant. In Volume 16, he and his peerage join the DxD team to help fight the remnants of the Chaos Brigade.
- Due to the extreme training that his body had endured, he gained an enormous amount of toki, a form of physical energy, and is a martial arts master. He can also utilize the Balance Breaker armor of "Regulus Nemea" (獅子王の戦斧（レグルス・ネメア） Regurusu Nemea?, lit. "Axe of the Lion King"), "Regulus Rey Leather Rex" (獅子王の剛皮（レグルス・レイ・レザー・レックス） Regurusu Rei Rezā Rekkusu?, lit. "Iron Skin of the Lion King"), one of the Longinus which he luckily encountered when its host died.
- Sairaorg's Evil Pieces include: Regulus (レグルス Regurusu?) (Pawn), a Nemean lion whose revival consumed seven pawns; Kuisha Abaddon (クイーシャ・アバドン Kuīsha Abadon?) (Queen), who has elemental powers, ability to create holes, and reflect attacks; Gandoma Balam (ガンドマ・バラム Gandoma Baramu?) (Rook), Ladora Buné (ラードラ・ブネ Rādora Bune?) (Rook) who can transform into a dragon; Beruka Furcas (ベルーガ・フールカス Berūka Fūrukasu?) (Knight) who rides a horse; Liban Crocell (リーバン・クロセル Rīban Kuroseru?) (Knight), who manipulates gravity; Coriana Andrealphus (コリアナ・アンドレアルフス Koriana Andorearufusu?) (Bishop) who tries to counter Issei's Dress Break ability; Misteeta Sabnock (ミスティータ・サブノック Misutīta Sabunokku?), (Bishop) who can seal an opponent's ability.
- Ajuka Beelzebub (アジュカ・ベルゼブブ Ajuka Beruzebubu?), formerly known as Ajuka Astaroth (アジュカ・アスタロト Ajuka Asutaroto?), is one of the Four Great Devils; he is Diodora's older brother and the creator of the Evil Pieces system and Rating Game. Ajuka is the only Devil that can rival Sirzechs in strength. He remodeled Issei's Evil Piece that gave him the ability to activate Illegal Move Trident. Ajuka has a special ability called the Kankara Formula (覇軍の方程式（カンカラー・フォーミュラ） Kankarā Fōmyura?, lit. "Equation of Military Supremacy"), which allows him to turn every phenomenon into equations and formulas and control it to make it into a special move of his own by increasing its speed and power. Ajuka is extremely powerful, as revealed in Volume 12 when he finishes off some of the servants of the Old Maou Faction who attacked him by turning their own powers against them, and it was mentioned that of the current Maous, only he and Sirzechs surpass the original ones.
- He is also a Super Devil and mutation of a Devil like Sirzechs.
Stray devils are devils who have betrayed or killed their masters.[S1 ep 3]
- Viser (バイサー Baisā?) is a stray devil who assumes the form of a centaur and shoots acid from her breasts.[S1 ep 3][importance?]
- Gentleman Alchemist (錬金術師の紳士 Renkinjutsu-shi no Shinshi?)
- Voiced by: Itaru Yamamoto
- An unnamed Stray Devil who is an anime-exclusive character in the OVA episode "I'm Harvesting Breasts!" He was captured by the Occult Research Club and interrogated by Grayfia in the Underworld.

According to Grayfia, the Gentleman Alchemist created the Breast Chimera so that every flat-chested girl in the world would have large breasts by eating its fruit. It was defeated by Rias' boosted Power of Destruction.
- Lord Gremory (グレモリー卿 Guremorī-kyō?)
- Voiced by: Shō Hayami
- The father of Rias and Sirzechs and the head of the family. He is a Marquis high-ranking devil.[S1 ep 2] He appears as a middle-aged man with red hair. Because he wants more pure-blooded Devil grandchildren, he pushes Rias to marry Riser.
- Venelana Gremory (ヴェネラナ・グレモリー Venerana Guremorī?)
- Known as Brunette Madame the Extinct[as], she is the mother of Rias and Sirzechs, and bears a striking resemblance to Rias except for her brown hair. As a descendant of the Bael family, she inherits her Powers of Destruction. She can seamlessly switch her demeanor from that of a proper, young noble lady to a fierce matriarch.
- Millicas Gremory (ミリキャス・グレモリー Mirikyasu Guremorī?)
- The son of Sirzechs Lucifer and Grayfia Lucifuge and Rias's nephew. Although his father is Lucifer of the Four Maous, it is not applied to Millicas, as it is required only for Sirzechs, thus Millicas' family name is Gremory and is next-in-line after Rias as family head. In the Volume 13 short story "The Worries of the Next, Next Heir" (which took place after Volume 12), it is shown that he has inherited Sirzechs' Power of Destruction when he had a training match with Issei during his stay at Issei's house. It is still unknown if he inherited any powers of the Lucifuge family from Grayfia.
- Lord Phoenix (フェニックス卿 Fenikkusu-kyō?)

- The mother of Sairaorg, originally from the Vapula Family (ウァプラ家 Vapura Ke?). She was in a comatose state a few years prior to the story. The Bael Family considered her and Sairaorg as failures because of Sairaorg not inheriting the Power of Destruction. Before her coma, she made Sairaorg promise her that he will become stronger than anyone, which later became Sairaorg's drive to become a Maou. She wakes up from her coma at the end of Volume 10.
- Diodora Astaroth (ディオドラ・アスタロト Diodora Asutaroto?)
- The heir to the House of Astaroth and Ajuka's younger brother. He is the Devil that caused Asia's excommunication from the Church and accusation of her being a heretic. After he revealed that he is an ally of the Chaos Brigade, it is further revealed by Freed that Diodora has a nun fetish and that all his servants are nuns and maidens that he acquired all over the world. That he'd seduce them away from the Church and then rape them, while recording it, when they were under his control. Seeing their complete despair and hopelessness makes it all the more enjoyable for him. He purposely injured himself so Asia, being extremely kind, would heal him so she'd get kicked out of the Church (Healing ability that can heal Fallen Angels and Devils is considered blasphemy) in order to get an opportunity to make her his servant. Originally he planned to 'rescue' Asia after Raynalle killed her so he'd have the excuse to turn her into a Devil while appearing to be the 'good guy.' He depises Issei for, in his terms, "stealing Asia from him", and attempts to kill him, but was defeated by the latter before Shalba Beelzebub fatally shot him with a light weapon.
- Diehauser Belial (ディハウザー・ベリアル Dihauzā Beriaru?)

- Mephistopheles (Mephisto Pheles メフィスト・フェレス?, Mefisuto Feresu)

Other groups and organizations
Fallen angels (堕天使 Datenshi?) are angels who used to serve God but because of their corrupt emotions, have descended into the underworld, and battle against the devils.[S1 ep 2] Their appearances are similar to those of the Angels, albeit with black wings and lacking a halo above their head. Even though they have been cast out from Heaven, Fallen Angels have somehow retained the ability to use light-based weapons. However, they receive damage like Devils do if they pray to God.

He is protective of his daughter Akeno, and initially despises Issei due to his misconception on Issei being "a Dragon that devours breasts", which was caused by Azazel who said that as a joke. He met Akeno's mother, Shuri Himejima, after he was injured and Shuri rescued him. In Volume 12, Baraqiel takes over Shemhazai's position as Vice Governor General after Shemhaza was promoted to Governor General.[LN 12]
Angels (天使 Tenshi?) are the beings from Heaven, which in Ishibumi's DxD world, supports all the religions, including the Church that Asia and Xenovia were part of.[LN 6 afterword] They have the powers to inflict pain upon devils due to their light-based powers.

In Volume 12, Indra sends the majority of the Hero Faction to the Realm of the Dead after taking all of their Longinus, claiming they have lost their value before retreating.

The Gear works in the opposite way of Issei's Boosted Gear, where upon contact, halves the opponent's power every ten seconds.[S2 ep 6] Vali can also add the opponent's halved power to his own, which contributed to the defeat of the Fallen Angel Kokabiel during his introductory chapter. Like Issei, he also has a Balance Breaker armor called Divine Dividing Scale Mail (白龍皇の鎧（ディバイン・ディバイディング・スケイルメイル） Dibain Dibaidingu Sukeiru Meiru?, lit. "Armor of the White Dragon Emperor"), which is similar to Issei's Scale Mail aside from it being white and having Dragon wings. The Divine Dividing also has the ability to halve the size of objects and living beings through the use of its "Half Dimension".
- In Volume 12, Vali uses a new form called the Empireo Juggernaut Overdrive (白銀の極覇龍（エンピレオ・ジャガーノート・オーバードライブ） Enpireo Jagānōto Ōbādoraibu?, lit. Silver Dragon Pole of Supremacy), which changes the color of his armor to silver. Like Issei's Cardinal Crimson Promotion, it does not consume his life. In this state, Vali can use an enhanced version of Half Dimension called "Compression Divider", which halves a specific target constantly until they vanish from existence.
- Arthur Pendragon (アーサー・ペンドラゴン Āsā Pendoragon?)
- A man who is the descendant of the Legendary King of Camelot, King Arthur. He is one of the two best swordsmen in the Chaos Brigade, earning the nickname "The Strongest Holy Sword User" (最強の聖剣使い Saikyō no Seikentsukai?). He is also a natural-born Holy Sword user like Xenovia. He wields one of the seven Excaliburs, "Excalibur Ruler" (支配の聖剣（エクスカリバー・ルーラー） Ekusukaribā Rūrā?), the strongest Excalibur fragment, along with the Holy King Sword Collbrande (聖王剣コールブランド SeiŌken Kōruburando?), the Sword in the Stone and the most powerful Holy Sword in existence. Arthur used the Excalibur Ruler to control Fenrir. In Volume 11, Le Fay gives the Excalibur Ruler to Irina after Arthur abandons the sword, as Fenrir no longer needs to be controlled by it. In Volume 12, after raiding the Realm of the Dead, killing many of Hades' Grim Reapers along with his team-mates, he confronts Yuto Kiba, challenging him after deeming him to be a worthy opponent for his Holy King Sword, telling Yuto that he will fight him when Vali fights Issei.
- Le Fay Pendragon (ルフェイ・ペンドラゴン Rufei Pendoragon?)
- Arthur's sister who is the descendant of Morgan le Fay. She is a witch who summons Gogmagog in battle. She is a huge fan of Issei's show. In Volume 14, she moves to the Hyodo Residence as a semi-permanent residence. In Volume 17 she successfully creates a summoning contract with Issei.
- Bikou (美猴 Bikō?)
- Voiced by: Makoto Yasumura
- The descendant of Sun Wukong and the current Monkey King. He likes to make fun of Issei and Rias, coining the nicknames "Oppai Dragon" (おっぱいドラゴン Oppai Doragon?, lit. "Breast Dragon") for Issei and "Switch Princess" (スイッチ姫 Suitchi Hime?) for Rias, which he would constantly use to address them (he even said he was proud of being the one to give two huge celebrities their nicknames). He is a Senjutsu user like Kuroka and Koneko, and like Vali, he is also a battle maniac. He also has his ancestor's legendary golden staff, the Nyoi-bo (如意棒 lit. "Mind Stick"?) and golden cloud, Kinto-un (筋斗雲 lit. "Somersault Cloud"?). Bikou is extremely fearful of his ancestor, the original Sun Wukong and first Monkey King, claiming that he is a total monster despite his age.
- Kuroka (黒歌?)
Kuroka is a nekomata and Koneko's older sister and the only major Vali Team member to not originate from a hero. A former Evil Piece that consumed two bishops, she is a SS-class stray devil that is despised by Koneko because she killed her own master. In volume 11, it is revealed that her master was a power-hungry scientist who wanted to test the limits of the nekomata's Senjutsu ability by using Konko as a test subject, and that Kuroka had protected Koneko from harm. Desiring to bear the child of a Heavenly Dragon, she joins Vali's team, but after Vali rejects her advances, she turns her eyes towards Issei. After reconciling with Koneko, she teaches Senjutsu and Youjutsu to her,[LN 11] and moves into the Hyodo Residence.[LN 14]
- Fenrir (フェンリル Fenriru?)
- Originally Loki's pet and son, a giant wolf with powerful fangs and claws that can kill God, Maou, and even a Dragon. Having God-like speed, Fenrir is considered to be one of the most dangerous beasts in the world rivaling the Two Heavenly Dragons, and is nicknamed the God-Devouring Wolf[av]. He is defeated by Vali and subjected by Arthur's Excalibur Ruler. As of Volume 11, Fenrir no longer needs to be controlled using Excalibur Ruler, but its abilities are reduced. He has taken a liking to Le Fay, and is often seen with her.
- Gogmagog (ゴグマゴグ Gogumagog?)
- A group of golems that were used as weapons of mass destruction created by the ancient God but all the Gogmagogs were abandoned in the Dimensional Gap. After hearing Orphis mentioning about a moving Gogmagog, Vali went to search for it to pick it up. He then gives it to Le Fay Pendragon.
Old Maou Faction
The Old Maou Faction (旧魔王派 KyūmaŌ-ha?, lit. "Old Satan Faction") is a faction of the Chaos Brigade consisting of descendants of the original Maous. They are the only group of Devils who resist using the Evil Pieces system, as they believe them to be a disgrace to Devils because they reincarnate Humans and other races into Devils. They are also against the Devils' current system, and seek to change it by overthrowing the current Maous. Vali Lucifer was part of the Old Maou Faction prior to him defecting and forming the Vali Team. The remaining three leaders were later defeated as of Volume 11 of the light novels, causing the Old Maou Faction to weaken. The remaining members were terminated by Ajuka Beelzebub in Volume 12.
- Shalba Beelzebub (シャルバ・ベルゼブブ Sharuba Beruzebubu?)
- The descendant of Beelzebub. He and the other descendants of the Maous (except Vali) believe that the current Devil system is mistaken and seeks to change it. He forcefully made Issei activate his Juggernaut Drive and was beaten because of it. He was the last remaining of the Old Maou Faction until Volume 11 of the light novels, where he fought against Issei and was terminated by him but was successful in placing Samael's curse on Issei, causing his death.
- Cattleya Leviathan (カテレア・レヴィアタン Katerea Reviatan?)

- Creuserey Asmodeus (クルゼレイ・アスモデウス Kuruzerei Asumodeusu?)
- The descendant of Asmodeus who fought against Sirzechs, but was killed by the latter.
The Hero Faction (英雄派 Eiyū-ha?) is a faction of the Chaos Brigade led by Cao Cao, the descendant of the ambitious ruler of China during the Three Kingdoms era. The faction is allied with Hades, the God from the Realm of the Dead, and it is also the most dangerous faction of the Brigade due to its members being Sacred Gear, Holy/Demon Sword, and Longinus wielders. The Hero Faction was defeated in Volume 12 when Indra sends the majority of its main members, Cao Cao, Georg and Leonardo to the Realm of the Dead, taking all of their Longinus from them. Siegfried died in battle while Jeanne and Heracles are captured.
- Cao Cao (曹操 Sōsō?)
- Cao Cao is the descendant of Cao Cao from the Chinese novel Romance of the Three Kingdoms and the leader of the Hero Faction. Like his ancestor, he has the eyes to find people with good potential. Cao Cao is a very charismatic person, as he was able to convince many Sacred Gear users to join the Hero Faction. He also believes that it is the responsibility as a descendant of a hero to destroy beings like Devils, Fallen Angels and Dragons that are threats to humans.
- He is a calculative and observant person, as he studies and research on his enemy before he battles them so he can read their movement and attacks. In Volume 9 he lost one of his eyes to Issei's attack, and later replaces the lost eye with Medusa's eye, granting him the ability to turn anything to stone. He is a technique-type who has polished his technique to utmost perfection. Because he is a human, he is physically weaker then Issei and Vali, yet in Volume 11 he singlehandedly takes down the Gremory and Vali groups while protecting Georg and Samael, which results in Vali calling him the "strongest human".
- His Sacred Gear is the True Longinus (黄昏の聖槍（トゥルー・ロンギヌス） Turū Ronginusu?, lit. "Holy Spear of the Setting Sun"), the ultimate Longinus and the same spear that St. Longinus used to kill Jesus Christ. His Balance Breaker, "Polar Night Longinus Chakravartin" (極夜なる天輪聖王の輝廻槍(ポーラーナイト・ロンギヌス・チャクラヴァルティン） Pōrā Naito Ronginusu Chakuravarudin?, lit. "Polar Night Becomes Chakravartin’s Bright Curved Spear"), is a sub-species that is much stronger than the actual Balance Breaker of the True Longinus, "True Longinus Geta Demelung" (真冥白夜の聖槍（トゥルー・ロンギヌス・ゲッターデメルング） Turū Ronginusu Getā Demerungu?, lit. "Holy Spear of the Pure White Night"). His Balance Breaker creates seven bowl-sized orbs called the Seven Treasures (七宝 Shippō?), each having a different ability. The True Longinus also has a forbidden form called the "Truth Edea" (覇輝（トゥルース・イデア Turūsu Idea?, lit. "Brightness of Supremacy"), which is similar to the Juggernaut Drive.
- Originally from the Chaos Brigade, Cao Cao betrayed them when he stole Orphis, their leader's, power and sided with Hades, the God from the Realm of the Dead, in an attempt to destroy both the Devils and Fallen Angels. After losing to Issei in Volume 12, Cao Cao, Georg and Leonardo was sent to the Realm of the Dead after having their Longinus confiscated by Indra. In Volume 18 he's released by Indra and decides to help the DxD face the threat of the Qlippoth and the Evil Dragons, while he still wishes to have a rematch against Issei.
- Georg (ゲオルク Georugu?)
- Georg is the descendant of Georg Faust, the person who made a pact with the legendary Devil Mephistopheles, and Cao Cao's right-hand man. He possesses the Longinus "Dimension Lost" (絶霧（ディメンジョン・ロスト） Dimenshon Rosuto?, lit. "Fog of Extinction"), a barrier-type Longinus that is listed among the top four Longinus. Though it has no offensive abilities, once the mist reaches the scale of countries, it can transfer an entire country and its people into the Dimensional Gap to be destroyed. The Balance Breaker of Dimension Lost, "Dimension Create" (霧の中の理想郷（ディメンション・クリエイト） Dimenshon Kurieito?, lit. "Utopia of Mist"), allows the user to use the mist to create a barrier and trap the user's opponents in a different dimension. Aside from the Dimension Lost, Georg is a magician capable of a diverse array of spells, ranging from Norse magic, demonic spells, Fallen Angel spells, black magic, white magic, fairy magic, and the Dragon Gate magic circle. He was sent into the Realm of the Dead along with Cao Cao and Leonardo by Indra in Volume 12.
- Leonardo (レオナルド Reonarudo?)
- A boy who wields the Longinus "Annihilation Maker" (魔獣創造（アナイアレイション・メーカー） Anaiareishon Mēkā?, lit. "Creation of the Demonic Beast"), which is also listed among the top four strongest Longinus and it has the ability to create any monster its wielder can imagine; however he has yet to fully master it. In Volume 11, he gets kidnapped by Shalba and was brainwashed by the latter into creating 13 gigantic monsters through its sub-species Balance Breaker, "Bandersnatch and Jabberwocky" (破滅の覇獣鬼（バンダースナッチ・アンド・ジャバウォッキー） Bandāsunatchi ando Jabawokkī?), to attack the Underworld. As with Kuroka of the Vali Team, he is the only major Hero Faction member to not originate from a hero. He was sent into the Realm of the Dead along with Cao Cao and Georg by Indra in Volume 12.
- Siegfried (ジークフリート Jīkufurīdo?)
- Siegfried is the descendant of Siegfried, the legendary Dragon-slaying hero in Nibelungenlied. He is the one of the top two swordsmen of the Chaos Brigade alongside Arthur Pendragon of the Vali Team, and is nicknamed "The Demon Sword User" (魔剣使い Makentsukai?) and the "Demonic Emperor". In the past, Siegfried worked for the Orthodox Church and is considered the best swordsman after Dulio, bearing the nickname "Chaos-Edge Sieg" (魔剣（カオスエッジ）ジーク Kaosu Ejji Jīku?), but he eventually left the Church and joined the Hero Faction.
- His Sacred Gear is "Twice Critical" (龍の手（トゥワイス・クリティカル） Tuwaisu Kuritikaru?, lit. "Hand of the Dragon"), a common Sacred Gear and the Sacred Gear Raynare mistook Issei to have possessed. Since it is a sub-species, instead of a gauntlet, it creates a third Dragon Arm on Seigfried's back and doubles his power. Its Balance Breaker, "Chaos Edge Asura Ravage" (阿修羅と魔龍の宴（カオスエッジ・アスラ・レヴィッジ） Kaosu Ejji Asura Revijji?, lit. "Feast of Asura and the Demonic Dragon"), allows him to have four Dragon Arms growing out from his back, with his power doubling for each. As a result, he has six Arms in total (including his real arms) in his Balance Breaker form. He has all five Demon Swords – Gram, Balmung, Nothung, Tyrfing, and Dáinsleif – and one Light Sword in his possession.
- He fights Kiba and Xenovia by himself and defeats them with ease in Volume 9. In Volume 11, he has a rematch with Kiba, resulting with the latter cutting off one of his Dragon Arms. In Volume 12, he fought against Yuto for the third and final time, injecting the blood of the original Maou which transforms his body into a monsterous spider while fusing with his Demon Swords. He eventually lost to the latter after Gram left him and chooses Yuto as their new wielder, corroding into dust after his defeat.
- Jeanne (ジャンヌ Jan'nu?)
- A beautiful blonde girl who carries the spirit of the Maiden of Orleans, Joan of Arc. She has a cheerful personality and likes to call people nicknames, such as calling Siegfried "Sieg-kun" and Irina "Angel-chan". She defeats Irina in Volume 9. In Volume 12, Jeanne faced off against Irina (for the second time), Akeno and Xenovia, taking the children of the Underworld hostage after feeling at a disadvantage. The situation was reversed by the returning Issei who saved the children, forcing Jeanne to use the same doping used by Siegfried, fusing with her Sacred Gear which creates a Holy Sword Armor, but was still defeated by Issei who simply uses his Dress Break to destroy the armor and shoots a Dragon Shot. She is captured after her defeat.
- Aside from carrying a rapier, Jeanne wields the Sacred Gear "Blade Blacksmith" (聖剣創造（ブレード・ブラックスミス） Burēdo Burakkusumisu?, lit. "Creation of the Holy Sword"), which is the Holy Sword version of Kiba's "Sword Birth" that can create numerous Holy Sword of different attributes. Her Balance Breaker, "Stake Victim Dragon" (断罪の聖龍（ステイク・ビクティム・ドラグーン） Suteiku Bikutimu Doragūn?, lit. "Holy Dragon of Judgement"), is a sub-species and it creates a Dragon made out of Holy Swords.
- Heracles (ヘラクレス Herakuresu?)
- A man who carries the spirit of the Greek mythological hero Heracles. He is a giant and a battle maniac. He defeats a drunk Rossweisse in Volume 9. In Volume 12, he faces against the Sitri Group where he won by taking the children of the Underworld hostage. He then faces Sairaorg in a one-on-one fight which he lost. He is captured after his defeat.
- His Sacred Gear is called "Variant Detonation" (巨人の悪戯（バリアント・デトネイション） Barianto Detoneishon?, lit. "Prank of the Giant"), which has the ability to explode the same time it attacks. Its Balance Breaker is called "Detonation Mighty Comet" (超人による悪意の波動（デトネイション・マイティ・コメット） Detoneishon Maiti Kometto?, lit. "Malicious Wave of the Superman"), which shoots missile-like objects.
- Rizevim Livan Lucifer (リゼヴィム・リヴァン・ルシファー Rizevimu Rivan Rushifā?)
- The current leader of Chaos Brigade and the third Super Devil. He is the son of the Original Lucifer and grandfather of Vali Lucifer. He always speaks in a childish way that carries no weight and filled with joke and ill intent. He is also known to be very vicious and brutal, even toying with his son, whom he deemed to be worthless, to persecute Vali and throw away Vali before killing his son. For most of his life he lacked any ambition or dream, but all changed once he met Euclid Lucifuge, and decided that he wanted to release the Trihexa(666) to destroy the Great Red and bring chaos to all the other worlds. He, along with Ajuka Beelzebub and Sirzechs Lucifer is one of the three Devils who are considered as Super Devils, with their abilities far exceeding even the Four Original Satans. He possesses a unique ability which can nullify all abilities of Sacred Gears and of Sacred Gear-enchanted powers just by touch.
- Euclid Lucifuge (ユーグリット・ルキフグス Yūguritto Rukifugusu?)
- Grayfia's younger brother who leads Grendel into attacking Kuoh Academy. Appears to have a disdain for his sister, but is only to hide her obsession towards her. He was able to create a replica of Boosted Gear by collecting information of the Sekiryuutei's soul and the Sacred Gear from Issei's original body left in the Dimensional Gap by using the Holy Grail. Unlike the original Boosted Gear, Euclid's Boosted Gear appears on the right hand with silver lining.
- Euclid is able to use the Balance-Breaker of the Boosted Gear by sacrificing the souls of several famous Dragon's since they are unable to make a copy of Ddraig's soul. The armor looks like Issei's Scale Mail, albeit with slight variations.
- Lillith (リリス Ririsu?)
- The spawn of Orphis created from her stolen powers in Volume 11 and is currently considered as Orphis by the Alliance and Chaos Brigade. Lilith looks exactly like Orphis except with a more devoid of emotion look. Rizevim Livan Lucifer named Lilith after his mother, Lilith, who was known as "The Beginning Mother of all Devils".
Dragons (ドラゴン Doragon?) make up some of the most powerful beings in High School DxD. Most of the dragons are neutral and do not ally with the three factions.[S2 ep 8] Besides Orphis there are the following dragons:
- Voiced by: Fumihiko Tachiki (Japanese), Christopher Sabat (English)
- Ddraig (ドライグ Doraigu?) is the Red Dragon residing in Issei's Boosted Gear.[S1 ep 12]. Nicknamed the Welsh Dragon (赤い龍（ウェルシュ・ドラゴン） Werushu Doragon?) and the Red Dragon Emperor (赤龍帝 Sekiryūtei?), he has the power to destroy gods and devils. In the past, Ddraig battles dragon arch-rival Albion, but their struggle was interrupted by the great war among the three factions. In anger, both dragons attacked the leaders of three factions, which led to their bodies being destroyed and their souls moved to two separate Sacred Gears.[S2 ep 8] Ddraig communicates telepathically with Issei on various occasions, giving him advice on his fights. He finds Issei's lecherous goals to be demeaning,[S1 ep 12] and gets annoyed whenever Albion and others call him the "Breast Dragon Emperor", even crying[LN 7] whenever he hears the word "breast".[LN 10] In Volume 16 he and Albion resolve their differences and allow Issei to unlock the powers they once had, yelling they are no longer afraid of breasts and butts.[LN 16]
- Albion (アルビオン Arubion?), known as the Vanishing Dragon (白い龍（バニシング・ドラゴン） アルビオン Banishing Doragon?), English Dragon, and the White Dragon Emperor (白龍皇 Hakuryūkō?), is the white dragon residing within Vali Lucifer in the latter's Sacred Gear.[S2 ep 8] Like Ddraig, Albion communicates telepathically with Vali.[S2 ep 6], and is annoyed to the point of crying that Issei is so obsessed with breasts.[LN 7] This became even worse after Odin, who wanted to know Vali's interest in women, called them the "Butt Dragon Emperor" (ケツ龍皇 Ketsuryūkō?). In Volume 16, he and Ddraig solve their differences and both yell they're no longer afraid of breasts and butts.[LN 16]
- Great Red (グレートレッド Gurēto Reddo?)
- Called the Apocalypse Dragon (真なる赤龍神帝（アポカリュプス・ドラゴン） Apkaryupusu Doragon?), Great Red is one of the two Dragons that are above the Heavenly Dragons known as the "True Dragon" (真龍 Shinryū?). The second largest Dragon after Midgardsormr, Great Red is known as the most powerful Dragon in existence. Called the "True Red Dragon God Emperor" (真なる赤龍神帝 Shin naru Sekiryūshintei?), and "Dragon of Dragons" (D×D（ドラゴン・オブ・ドラゴン） Doragon obu Doragon?, "DxD", for which the series is named after), Great Red lives in the Dimensional Gap and does not interfere in the world.
- In Volume 12, Great Red helped Orphis and Issei by saving them from the crumbling dimension and restored Issei's body with his powers. He also lends Issei his power during his fight with the Jabberwocky created from Leonardo's Annihilation Maker, claiming that the "Beast" (referring to Jabberwocky) was glaring at him. After the battle, he returns to the Dimensional Gap while saying "Zoom Zoom Iyaaan" (from Oppai Dragon's theme song) over and over to Issei and Ddraig's dismay.
- Great Red represents dreams.
- Vritra (ヴリトラ Vuritora?)
- An evil Black Dragon known as the Prison Dragon (黒邪の龍王（プリズン・ドラゴン） Purizun Doragon?).[S2 ep 9] When Vritra was vanquished and sealed into Sacred Gears, its soul was divided into 4 parts: Absorption Line, Blaze Black Flare, Delete Field, and Shadow Prison. These four parts of Vritra's soul have different appearances and have been collected and sealed in Saji's body by Shemhazai, thus restoring Vritra's consciousness. Azazel hypothesized that due to contact with Issei, Vritra's consciousness appeared and might possibly unify all the different Sacred Gears because the other Sacred Gears melted together. Vritra possesses a wide range of special abilities. Though its power might be the lowest amongst the Dragon Kings, Vritra is the king of techniques in terms of variety and unconventionality.
- Yu-Long (玉龍（ウーロン） Ūron?)
- A Green Asian Dragon and Dragon King known as the Mischievous Dragon (西海龍童（ミスチバス・ドラゴン） Misuchibasu Doragon?) and West Sea Dragon Child (西海龍童 Saikai ryūdō?) who went missing along with Sun Wukong prior to the series. He is the youngest among the Five Dragon Kings. He appeared with the original Sun Wukong in Volume 9 during the class trip to Kyoto, aiding Issei and the others against Cao Cao by fending off Yasaka.[LN 9]

In Volume 14, he made a pact with Asia after being freed of his own contract with Azazel.

He calls his father, Loki, "Daddy" and his brother, Fenrir, "Doggy".[LN 7]
- Crom Cruach (クロウ・クルワッハ Kurō Kuruwahha?)
- A Dragon known as the Crescent Circle Dragon (三日月の暗黒龍（クレツセント・サークル・ドラゴン） Kuretsusento Sākuru Doragon?, lit. "Dark Dragon of the Crescent Moon"). A mythical Dragon that was only named in one of the novel's short stories, it was said to be a Dragon that rule over death. He was also mentioned in volume 14 by Azazel when he was talking to Issei about evil dragons. According to legend, it was destroyed by the Christian religion while some say that it just went into a deep sleep.
- It is said to be the strongest Evil Dragon. He is currently affiliated with the Chaos Brigade's Qlippoth along with the other Evil Dragons. Crom Cruach first appeared in Volume 16 where he was introduced by Marius Tepes as their bodyguard.

He has the ability to shapeshift from his dragon form to human form.
- Grendel (グレンデル Gurenderu?)
- An Evil Dragon known as the Crime Force Dragon (大罪の暴龍（クライム・フォース・ドラゴン） Kuraimu Fōsu Doragon?, lit. "Berserker Dragon of Great Sin"). Grendel was the Evil Dragon that was slain by the original Beowulf. He was later revived by the Chaos Brigade. Grendel is a psycho Dragon that is only interested in fighting and killing. It is one of the main antagonists of Volume 14. The strength of his punch was said by Issei to be stronger than Sairaog's.
- In Volume 16, he appears before the Occult Research Club while they were on the way to retrieve Valerie.

It is said that long ago, Samael was the perpetrator that influenced the first man, Adam and Eve, to eat the Fruit of Wisdom, and was cursed by God to become a Dragon because of God's hatred on Dragons. Following the curse, it was sealed in the deepest part of the Underworld, Cocytus. Hades summoned it from the Underworld and gave it to Cao Cao temporarily as part of the alliance. During the battle between Cao Cao and the Gremory and Vali teams, Samael's poison was injected into Vali's body, while Issei received the poison through an arrow fused with Samael's blood during his fight with Shalba.

- Sun Wukong (孫悟空 Son Gokū?)
- Bikou's ancestor, he is the first Monkey King who is known as "The Great Victorious Fighting Buddha" (闘戦勝仏（とうせんしょうぶつ） Tōsen Shōbutsu?). He appeared alongside Yu-Long in Kyoto, helping Issei and his friends during their fight against Cao Cao. He is extremely powerful, as he was able to overpower several members of the Hero Faction within seconds, a considerable feat as they were all Sacred Gear and Holy Sword users. He was even able to block Cao Cao's True Longinus with a single finger, which was even complimented by Azazel as the True Longinus is a spear capable of killing God.

She was captured by Cao Cao under the intention of opening the Dragon Gate to test the effect the Dragon Eater Samael can have on Great Red. She is eventually rescued by Issei and his friends who are on their trip in Kyoto. In Volume 12, Yasaka led her fellow yōkai to assist the Underworld in their crisis, easily disposing of one of the Bandersnatch.
Vampires (吸血鬼 Kyūketsuki?) are a race of supernatural creatures even more proud and aloof than Devils. While some Devils, particularly the Gremory clan, treat their slaves/servants like family or allow advancement in rank, while for a Vampire to be treated as high-class, they have to be born into a high-class Vampire family. Transformed vampires are despised and eternally low-class and none of the clans are considered to even be close to treating their slaves even remotely as family. Gasper is despised for being half-human, his out-of-control Sacred Gear, and apparently the "Darkness" Vampire powers he used to defeat Georg. Like the stories tell, Vampires are weak against sunlight, garlic and holy items. Although Gasper's clan, the Vladi, have a clan trait of being Daywalkers, meaning sunlight won't kill or hurt them any more than it does Devils. Vampires are mostly cut off from other groups by preference, and word is that fighting between clans broke out shortly after one clan got hold of a Longinus user.
- Elmenhilde Galnstein (エルメンヒルデ・カルンスタイン Erumenhirude Garunsutain?)
- Nicknamed Elmen (エルメン Erumen?), she is a member of the Carmilla Faction (カーミラ派 Kamīra-ha?), an all-female Vampire faction. She appears in Volume 14 as a special Envoy of the Carmilla Faction wanting Gasper to join their side.
- She reappears in Volume 16 as the escort for the Occult Research Club in the Carmilla Territory. She later appears again with Bennia's help to inform the Occult Research Club that the Vampires from the Carmilla Faction will start their action to suppress the coup d'etat group of the Tepes Faction. She is last seen after the chaos left behind by Rizevim and his group using the mass-produced Evil Dragons transformed from the modified Vampires in both the Tepes and Carmilla Factions, where she is noticably distrought about the damage to her homeland.
- Valerie Tepes (ヴァレリー・ツェペシュ Varerī Tsepeshu?)
- A Vampire belonging to the Tepes Faction (ツェペシュ派 Tepeshu-ha?), an all-male Vampire faction. Like Gasper, she is a Dhampir and the two had been childhood friends. She was the one that helped Gasper escape from the Vampire world. After helping Gasper escape, she awakened her Longinus and indirectly helped her clan to enhance its power. She wields the Longinus "Sephiroth's Grail" (幽世の聖杯（セフイロト・グラール） Sefuiroto Gurāru?, lit. "Holy Chalice of the Secluded World"), one of the four Holy Relics alongside the True Longinus.
- Valerie's Longinus is a sub-species where she has a total of 3 Holy Grails. The Sephiroth Graal has the ability to make contact with the principle of life, where Valerie has been forcefully told about how the life and soul is made. Due to the nature of the Sephiroth Graal, Valerie also takes in the mind and the concept of the dead, the living, and various other things as she uses the Holy Grail which resulted in her current broken state by the abundance of thoughts that enters her heart and soul when overusing the Sephiroth Graal. A side effect of the corrosion on Valerie caused by overusing the Sephiroth Graal is she can talk with the dead from the other world. In spite of this, she can still show some emotions like happiness. She had two out of her three Holy Grails extracted from her by Rizevim Livan Lucifer and Marius Tepes, but the grail stolen by Marius was later returned to her. Unfortunately, the stress of having her second grail removed was too much for her body and was put in a comatose state. After the chaos done by Qlippoith, she was seen being carried by Gasper from the basement and was taken to Grigori's research institute.
- Marius Tepes (マリウス・ツェペシュ Mariusu Tsepeshu?)
- A pure-blooded vampire and a member of the Tepes Faction, a Male-dominated Vampire faction. He is also Valerie Tepes half-brother.
- Marius appears in Volume 16, introducing himself to the Occult Research Club as the new Mayor of the Tepes Faction after overthrowing his father in a coup d'etat. He later plotted to extract Valerie's Longinus from her body, finalizing the extraction ceremony in front of the Occult Research Club. After obtaining the Holy Grail, Marius becomes arrogant believing that he has attained an even greater height, resurrecting even after an attack by Rias which destroyed the upper half of his body. His arrogance, however, proved to be his undoing as it angered Gasper into using his "true form" and was completely devoured by the darkness released by Gasper much to his horror as the Holy Grail proves useless against Gasper's power.
- Lord Vladi
- Gasper Vladi's father and the current head of the House of Vladi. Unlike most Vampires, Lord Vladi doesn't seem to despise or discriminate other species, though he is shown to have no problem discriminating his own son. Despite so, he was shown to be somewhat glad that Gasper has found a place that accepts him.
One of Issei's best friends that make up the Perverted Trio (変態三人組 Hentai San'nin-gumi?). Matsuda has a shaved head, and is a self-proclaimed lolicon.[LN 1] He is jealous of Issei's relationship with the girls of the Occult Research Club.[S1 ep 1] and spreads some rumors about Issei.[S2 ep 1]
Issei's other friend in the Perverted Trio, he wears glasses, and is able to determine a girl's body measurements by staring at a girl.[LN 1] He too is jealous of Issei's relationship with the girls of the Occult Research Club, and also spreads bad rumors about him.[S2 ep 1]
- Freed Sellzen (フリード・セルゼン Furīdo Seruzen?)
- Voiced by: Yoshitsugu Matsuoka (Japanese), Ben Phillips (English)
Freed is a recurring antagonist in the series; he is a human priest who kills devils and the humans who make contracts with them, claiming they are already stained beyond salvation. Although he has worked for the Vatican, he does not believe in God from the start, and desires to kill monsters, which makes him a wanted criminal as well as an enemy to the devils. He wields a sword of light and a pistol that fires devil-purging rounds. As a "stray exorcist", he employs Asia Argento to set up a barrier at his home.[S1 ep 3] but is later revealed to be in cahoots with fallen angel Raynare.[S1 ep 4] He is sought after by Xenovia and Irina for killing a priest,[S2 ep 3] and stealing the Holy Swords such as Excalibur Mimic. He sides with fallen angel Kokabiel of the Grigoris,[S2 ep 4] where he has merged four of the seven Excaliburs. He is defeated by Yuto with a slice to his torso, but returns in Volume 6 as part of the Chaos Brigade where his body is attached to a chimera, only to be finally killed by Yuto.[LN 6]
A muscular guy who wishes to become a magical girl, he is referenced in the early light novel volumes. He ends his sentences with "Nyo" (にょ?).[S1 ep 6] In one of the anime episodes, Issei sets Matsuda and Motohama up on a date with Miltan and a friend.[S1 ep 8]
A bespectacled student with braids, she is Asia's friend who regularly appears in the second season of the anime adaptation.[S2 ep 3] She likes to tease Asia about her crush on Issei.[S2 ep 1] One of her hobbies is giving her romance advice like welcoming Issei home in a naked apron,[S2 ep 4] or made-up traditions like bloomers are the ideal Japanese sportswear for dodgeball. She later reveals an ability to calculate a male's "manhood" size just by looking.[volume & issue needed]
- Valper Galilei (バルパー・ガリレイ Barupā Garirei?)
Known as the Archbishop of Annihilation, is a human excommunicated member of the Church who was responsible for the Holy Sword Project.[S2 ep 3] He reveals that he was able to isolate the genes responsible for wielding the Holy Swords, and transfer it to other subjects so that they can wield Holy Swords. He has the participating children terminated, and harvests their souls into a crystal that he later gives to Yuto Kiba. He is killed by Kokabiel.[S2 ep 5]
- Slash Dog (刃狗（スラッシュドッグ） Surasshu Doggu?)
Slash Dog is a human who possesses the Longinus Canis Lycaon[ax] and works for the Fallen Angels. According to Azazel, he does not get along with Vali. His name comes from one of Ishibumi's previous works, SLASH/DOG.
- Kiyome Abe (安倍 清芽 Abe Kiyome?)
The Captain of Kuoh Academy's Tennis Club who comes from a human family of beast tamers. Initially she is very wary of the Occult Research Club since, as a human, she believed all the rumors of Devils being pure evil, contracts held to the letter with the spirit ground up, and thought they were after her soul. Since she needed to borrow Issei for an unnamed reason, and the Occult Research Club needed a report on monsters ASAP (Rias has to do the report to earn credits at Demon School, if she's ever short she'll have to return to the Underworld, with her servants, and attend Demon School in person.) As Rias did not want to loan Issei and Abe was wary of them, it was decided to have a tennis match where the winner got what they wanted for free, no strings attached. For the match, Abe used a Harpy (lost) and a Lamia (won) for the two singles games and played doubles with Christie against Rias and Issei for the tie-breaker. Christie's freezing breath was hampering Issei's meager skills so he put on Honda (who was as upset as Issei that Yuki-onna weren't beautiful maidens, but yetis) which help Rias and him win. Later on, she asks Rias if she can borrow Issei to cancel an arranged marriage her father was pushing for. Rias having escaped an arranged marriage herself agrees, but only if the whole group can come in exchange for some information Kiyome knows about various monsters and mythical beasts. After succeeding, in some rather strange ways, Kiyome is attracted to Issei because of how cool he looked during the duel. Although whether anything will come of this is unknown at this point.
Kiyome's club members that are monsters include: Christie[ay], a yuki-onna who resembles a yeti in her monster form, who develops a crush on Issei after the latter wears Honda's armor; "No-Head" Honda[az], a dullahan (animated armor), who gives immense strength to its we are; and Estleena[ba], a mermaid that has a Tuna fish head and human legs, much to Issei's dismay.
- Shuri Himejima (姫島 朱璃 Himejima Shuri?)
Akeno's mother and Barkiel's wife. A priestess coming from a well-known shrine, Shuri saved his life when he was injured, and fell in love with him, but her family believed she was being brainwashed. In the rescue attempt, she sacrifices herself to defend Akeno while Barkiel was away, which results in Akeno's hatred towards her father for not protecting her mother. It is revealed in one of the side stories that Shuri enjoys sadist activities with her husband.[volume & issue needed]
- Belzard (ベルザード Beruzādo?)
- One of the former wielders of the Boosted Gear and is known as the strongest possessor, defeating two White Dragon Emperors in his lifetime.[LN 9]
- Elsha (エルシャ Erusha?)
- Another former wielder of the Boosted Gear and is known as the strongest female possessor. She appears in Volume 9 alongside Belzard inside the Boosted Gear, providing Issei the "box" to tap into the full power of the Red Dragon Emperor.[LN 9]
Rossweisse's grandmother. A former Valkyrie and a very famous magic user, she's contacted by Sona to be an expositor at the inauguration of her school. She's not shy about asking her granddaughter the status of her relationship with Issei. Just like Rossweisse she tends to speak in her native country accent whenever frustrated. She is among the few persons that investigated the existence of the Trihexa.
- Walburga (ヴァルブルガ Vuaruburuga?)
A Magician and leader of the Hexennacht, a group of stray magicians. She's the wielder of one of the Longinus, "Incinerate Anthem", the Holy Cross. Walburga is a sadist who loves looking at people in pain. She has also allied with Rizevim Livan Lucifer after the latter's reemergence.
- Yaegaki Masaomi
The resurrected "Avenger" and wielder of Kusanagi. He was originally affilliated with the Church but was killed by them for falling in love with the previous Devil that governed the Kuou Town.
- 666 (Trihexa) (６６６（トライヘキサ） 666 (Toraihekisa)?)
Trihexa, also known as the Apocalyptic Beast[bb], is a powerful being which sealed by the bible God caused his(God's) exhaustion when he joined the Great War. 666 is the only one who has power equal to that of Great Red.
Ishibumi had previously worked on a horror genre series two years prior to the publishing of the first light novel for High School DxD. In the volume 1 afterword, he mentions that he changed his writing style, and wanted to develop one in the school-life, love-comedy, battle, and fantasy genre. His main character Issei was made into a lecherous guy at the request of his editor. For the first volume, he made Rias a second lead character and heroine, and Asia to be the second heroine. Some of his characters are loosely referenced from the Bible, non-fiction books, and mythology. He created a world where the war between the three main factions (angels, devils, and fallen angels) is over, and where many famous angels and devils have already ceased to exist. He also added characters and legendary beasts from a variety of places from Norse mythology to Japanese Yokai.[LN 1 afterword]
In Volume 5 of the light novels, Ishibumi writes that he likes to pair the main characters: Rias and Akeno as the big sister duo, Asia and Xenovia are the church-related duo who become friends, Gasper and Koneko are the young first-years, and Issei and Yuto are the guys.[LN 5 afterword]
When Jamie Marchi was writing the dub script, she noted it was a breast-centric show, even noting that they have sound effects for when they move. She saw the main heroine Rias was calm and stern and a character that that she isn't used to playing. She also liked giving the side characters more personality. Ishibumi also agrees with the appeal of the characters' oppai (breasts) especially in later volumes of the light novels, and had planned to make the heroines more erotic,[LN 1 afterword] especially in the side story volumes that focus on comedy.[LN 7 afterword]
Theron Martin of Anime News Network praised the character development, in which Rias "gradually starts to be attracted to Issei for his unqualified admiration and devotion," and calls Asia Argento "a fairly typical helpless, innocent, kind-hearted moe type, one who becomes interesting in part because her transition from being a nun to being a devil is fraught with problems." He also said that Issei's "interactions with his perverted best friends [Matsuda and Motohama] are also occasionally good for laughs, as are his own reactions to situations and his amusing alarm clock." Martin praised the English voice acting of Scott Freeman, Chloe Daniels and Felicia Angelle, but said that Teri Rogers made "Akeno sound cheerfully friendly without ever really infusing in the suggestive and sadistic undertones" and said that Jamie Marchi "often does not sound quite right as Rias even though she performs the role well."
Davey C. Jones of ActiveAnime said that the characters "have a good range of different types, no one looks the same, and each has an individual personality and powers." A reviewer for T.H.E.M. Anime Reviews said that "[TNK's] animation is generally doing those characters all kinds of favors" and although the reviewer said that the English voice actors are "a bit of an uneven bunch," the dialogue "keeps itself on a relatively informal level, with gratuitous usage of generally inoffensive sexual slang on the parts of Issei and his two friends." Sheena McNeil of Sequential Tart not only liked the diversity of the characters, but also liked the designs and personalities in them. McNeil also praised the Japanese and English voice acting in the series as well.
