Short for the "Board Of Archaeological Research Department", BOARD uncovered the seal Undead Cards and developed the first two Rider Systems.
Kazuma Kenzaki (剣崎 一真 Kenzaki Kazuma?) was chosen by the B.O.A.R.D. organization to use the sealed Category Ace of Spades (Change Beetle) to become Kamen Rider Blade (仮面ライダーブレイド Kamen Raidā Bureido?). He has a good heart and believes in fighting to protect humanity. He would ultimately sacrifice his own human existence by mutating into the second Joker after excessive use of his Rider form's King Form transformation. This forces a stalemate in the Battle Fight while there is more than one Undead, keeping mankind safe, but more importantly, allowing his friend, Hajime (Chalice/Joker) to continue his life as a human.
Sakuya Tachibana (橘 朔也 Tachibana Sakuya?) was originally a researcher of BOARD's Humanity Foundation who graduated from the Sazahaibu University and was selected to be the user of Rider System 01, using the sealed Category Ace of Diamond (Change Stag) to become Kamen Rider Garren (仮面ライダーギャレン Kamen Raidā Gyaren?). From the beginning of the series, Tachibana begins to suffer a form of cellular breakdown, and only by sealing the Undead did the process slow down. Tachibana blames Karasuma for his condition, and the fact that Kenzaki was appointed as his backup rider in case he could not cope on his own did not improve his relationship with Karasuma. When he attempted to seal the Locust Undead before it attacked BOARD, Tachibana is forced to abduct Karasuma for answers prior to him going into a coma. However, it is only revealed later that the "Karasuma" he safeguarded was only a decoy as Tachibana learns that it is actually his subconscious fear that is causing the breakdown.
Tachibana encounters Isaka, the Peacock Undead, who recruits him by removing his fears with exposure to Schuld Kestner seaweed, an extinct plant that intensifies the aggressive nature of the subject. Though he became more aggressive and worked under Isaka for more of the seaweed, Tachibana was unaware of the eventual damage it would do to his nervous system. Though his dear friend Sayoko Fukasawa tries to warn him, Tachibana does not listen until he learns that Isaka murdered Sayoko for meddling in his affairs. Tachibana overcomes his fear while defeating the Peacock Undead and sealing him.
Later in the series, as restitution for being manipulated by an Undead, Tachibana takes Mutsuki under his wing, attempting to help him stay in control of the Spider Undead. During the final few episodes, Kamen Rider Garren came face to face with the Giraffa Undead and battled it out with him. Despite the Undead warning him the consequences of Hajime being the last Undead standing, thus making him champion of the Battle Fight, Garren insists on believing in his friend before the two fall off a cliff. The battle ended with Garren nowhere to be found and the King Undead sealed leaving the Joker as the winner. He is found upon the arrival of the Chief telling Kenzaki that he was saved because of him.
Shiori Hirose (広瀬 栞 Hirose Shiori?) is a 20-year-old lady who is one of the few remaining BOARD members after it was attacked by the released Undead, helping the Riders by detecting the Undead on her Undead-searching computer. She seems to care for Kenzaki very much.
Kei Karasuma (烏丸 啓 Karasuma Kei?) is the President of BOARD. A 48-year-old professor who created the Rider systems 01 and 02 (Garren and Blade), as well as the Leangle System (03), while he was under control of Isaka. During his travels, he befriends Noboru Shima, whom he entrusted the Rouze Absorbers to despite knowing he was an Undead. He is also aware of the side effect of Kenzaki's King Form as well as Tennoji's plans of the fake Battle Fight. 4 years after the series end he and Tachibana tried to cover 52 cards, when Albino Joker appeared and unsealed Undeads, who attacked and killed Karasuma.
Yoshito Hirose (広瀬 義人 Hirose Yoshito?) is Shiori's father, the one responsible for breaking the Undead's seal in a fit of madness, dying in the process. He created the Trial-series Undead Trial B (トライアルB Toraiaru Bī?) in his image to protect Shiori, possessing all his creator's memories. However, Trial B was reprogrammed by Tennōji to continue to monitor the fixed Undead battle and remove potential threats before he sacrifices to protect Shiori from Trial G.
Hiroshi Tennoji (天王路 博史 Ten'nōji Hiroshi?) is the chairman of BOARD who intentionally set up the series of events in the fake Battle Fight and the creation of the Category Ace Kerberos, so that he could have his warped dream of a new world order with himself as its ruler. In the end, he was murdered by the Giraffa Undead after he was defeated by the Riders with his dreams shattered.
Hajime Aikawa (相川 始 Aikawa Hajime?) is a mysterious man who is the Joker Undead, the most feared of the Undead as his victory in the Battle Fight would mark the end of all life on Earth. Unsealed around the time the other Undead were released, Joker battled The Mantis Undead and uses the sealed Category Ace of Hearts (Change Mantis) to become the wild card Kamen Rider Chalice (仮面ライダーカリス Kamen Raidā Karisu?). He later seals the Human Undead, who willingly surrendered to him without resistance, using the card to assume human form. The effect of prolonged use of both of these cards to assume their forms resulted with both the Human Undead's compassion for life and the Mantis' Undead's fighting spirit collectively suppressing Chalice's natural destructive impulse as the Joker. However, many of the Royal Club Undead who knew his true identity made attempts to dispose of him. One such attempt by the Giraffa Undead ended with an innocent bystander witnessing the battle being mortally wounded by accident in the skirmish. The dying photographer handed him a photograph of his family and Joker decide to protect his family in which he did to atone for his death. The Joker took on the identity of freelance photographer Hajime Aikawa since then. Though he thought less of humans originally, Hajime's time in lives at Jacaranda Cafe with Kurihara's family warmed him up to humans and eventually, he wish for himself to be human instead of being the Joker.
Though he and Kenzaki disliked each other earlier, Hajime's growing humanity eventually warms up to Kenzaki, who became a dear friend of his, then Garren and later to a limited extent, Mutsuki as well. But when the Caucasus Undead takes most of his cards, the sealed Mantis Undead among them, it causes Hajime to regress back into the Joker after attempting to resist until Leangle unseals Hajime's cards and use the Undead against him. Even after managing to reseal them all, the Joker failed to regain control and goes on a rampage until he is provided with the Evolution Paradoxa, allowing Hajime to finally have full control of himself. This lasted until the Giriffa Undead was sealed, leaving the Joker the final victor of the Battle Fight. Hajime loses control once more and his impulse as Joker comes forth with the Stone of Sealing creating his army of DarkRoaches to eliminate all life. In the end, Kenzaki is the only one to fight him head on, with Hajime pleading Kenzaki to defeat and seal him.
While in the series ends with Hajime being allowed to live as a human thanks to Kenzaki sacrificing his own humanity and becoming another Joker to put the Battle Fight in a stalemate, the movie provides an alternate ending to the fight that has him sealed by Blade. However, the actions of the Albino Joker four years later forces Kenzaki to have Leangle unseal Hajime to aid in protecting Amane as his true self and later as Chalice. In the end, Hajime sacrificed himself by switching places with Amane to save her and give the other Riders an advantage over their enemy. His spirit was later shown watching over Amane, the girl assured by Kenzaki that Hajime will always be there.

He gains a thirst for power as the Spider Undead takes over his mind, using him to attack the other Riders. But, later he is redeemed thanks to the sealed Tiger and Tarantula Undead giving Mutsuki the strength to force the Spider Undead out and the chance to fight on his own power, eventually allowing him to seal the Spider Undead properly and using the Rider System without any adverse effects, while psychologically properly completes him as a man capable of being a rider.
