Otokojuku (男塾? Man Private School) is a private boys' school in Tokyo, established over 300 years ago. The headmaster Heihachi Edajima gathers delinquents from all over Japan and trains them to become the leaders of the next generation.
Amongst the students, the first years are viewed as slaves, the second years as oni, and the third years as Enma. The third years take instruction from the headmaster alone, as the rest of the instructors are not at the same level as them and can not outpower them enough to punish them. The third years run things from the Tendo Shirne (天動宮?), and will tour all over Japan in order to settle disputes.
Anyone who fails to do anything in Otokojuku must undergo a Otokojuku Specialty (男塾名物? Otokojuku Meibutsu). The outside world is told that these are average school events and special lessons, but in actuality they are various torture methods and duels. A few specialties are known of outside the school, as evident when Hidemaro knew of the Oil Bath before enrolling.

Mount Fuji Foot Treasured Hell Temple), which leads to the skeleton and corpse littered Anryoudou (暗魎洞? Dark Spirit Cave). And the end of it is two giant iron balls called the Houkongyoku (砲魂玉? Cannon Spirit Ball), which must be rolled up to the summit of Fujiyama. At the check-points, each team chooses one representative to take part in a fight. Whichever surviving side wins in the end is awarded the Shouhyoukan (勝彰巻? Victorious Shadow Scroll) as champion.
Edajima is the only survivor in its 300-year history, having achieved a magnificent victory 50 years ago in 1950 (Showa 25). Inside Otokojuku is a memorial stone monument in honor of those who lost their lives.

He is fluent in multiple languages and is a master of various secret techniques, always wears a white hachimaki, carries around a katana, has a laid-back attitude and sense of humor and often dozes off during class. Very little is known about his past or how he got so strong. In the past, he trained at a temple to learn the Shoukyuu Soudan, and his son Shishimaru in Akatsuki!! Otokojuku underwent the same training. After graduating from Otokojuku, he enrolled in University of Tokyo, and after that he studied abroad at Harvard University. In Akatsuki!!

- Shinkifuukon (暹氣虎魂? Rising Tiger Spirit)

- Shoukyuu Soudan (翔穹操弾? Soaring Manipulation Bullet)

(富樫 源次, Togashi Genji)
Voiced by: Ken Yamaguchi. The leader of the Otokojuku Shock Corps and a close friend of Momo since the beginning of class. He is a brawler and uses a dosu knife. He always wears a tattered school hat, which is a memento from his late older brother Genkichi (Voiced by: Michihiro Ikemizu) who was killed years ago in the same battleground where Togashi fights Senkuu. He has a scar underneath his right eye from a fight 3 years before enrolling in Otokojuku. He does not have any formal martial arts training, but he shows an incredible fighting spirit. Although he has great fights against Hien and Senkuu, he later becomes a comical character and mostly serves as a commentator with Toramaru. He is well known for risking his life and seeming to die, only to return alive and well later. In Akatsuki!! Otokojuku he has become Edajima's secretary. Additionally, his father, Genzo Togashi, appears in Peerless: The Legend of Edajima Heihachi as an ace pilot for the Imperial Japanese Navy.

Although initially depicted as strong enough to knock out Momo and break off a piece of the ice ring with a single punch, he later mostly serves as a commentator with Togashi. Though he accepts this position and even calls himself the "Eternal Commentator of Otokojuku", whenever he does fight again he fights bravely. His specialty is sumo and he was a yokozuna back in his hometown. He will often fight wearing only his fundoshi. His father Ryuta appears in Peerless: The Legend of Edajima Heihachi in a maximum-security army prison, holding a suspended ceiling, the same way his son was introduced.

In the manga he refers to himself in the first person as boku (僕?), but in the anime he says ore (オレ?).
The live action film focuses a lot on his experience after enrolling in Otokojuku, making him a sort of second main character after Momo.
(松尾 鯛雄, Matsuo Taio)
Voiced by: Juji Matsuda. The comic relief character along with Hidemaro and Tazawa, he is also the lead yeller and bell ringer in the school's ōendan. He has an odd hairstyle, similar to the title character in Sazae-san. His bad premonitions often come true. His father, Koisachi Matsuo, appears in Peerless: The Legend of Edajima Heihachi as a similar comic relief role.
(田沢 慎一郎, Tazawa Shinichirō)
Voiced by: Masato Hirano. The self-proclaimed "Intelligence of Otokojuku". He is also called the "Brains of Otokojuku", but he often messes up simple things like multiplication tables, making his knowledge questionable. However, he does have rare moments where a glimpse of true intelligence can be seen from him. In the Dai Ishin Paren Seiha Arc, it was his idea to form the "10,000 Man Bridge" human bridge. He was renamed Ippei Tazawa (田沢一平? Tazawa Ippei) in the anime.

(椿山 清美, Tsubakiyama Kiyomi)
Voiced by: Kazuhiro Nakata. A large student with a rather timid personality.

Bamboo Thicket Sword Sumo). Midway through the match he learns that Gonda had made yakitori out of his pet Pee-ko (ピー子?), so he becomes enraged and avenges the little bird.

2nd Year Students
(赤石 剛次, Akashi Gōji)

It is a very sturdy sword, the only time it ever cracked was when it was hit by J's Magnum Steel Knuckle. He has silver hair, although it was changed to black in the anime.
Both first and second years fear him, and even the third years recognize his great skills. He fights as a supporter for the first time in the Tenchou Gorin Dai Bukai finals. After his fight against Hornet in the Battle of the Seven Tusks, he uses his Zanganken technique in order to save the other Otokojuku students from a trap and then dies. He entrusts his katana to Momo.
After the series ends he is confirmed to have lived. His son Juuzou appears in Akatsuki!! Otokojuku.
Voiced by: Ginzō Matsuo. The leader of the 2nd years in Akashi's absence. Depicted as the main tormentor of the 1st years, he usually wears an overly forced smile, but when mad his face changes to one of a furious psychotic killer. In Akatsuki!! Otokojuku, decades have passed but he has yet to graduate and therefore is still enrolled in Otokojuku.

He has won the Dai Ishin Paren Seiha three consecutive times, and he uses his power to defend his position. In the past he challenged Edajima to a duel but suffered his first loss, and came to realize the level of Edajima's greatness.

During the battle against Rouroukan in the Tenchou Gorin Preliminary League he attacks Sou Reigen, but Sou Reigen destroys his poison eye with his Shoukyuu Soudan and breaks his spine, killing him. He is the first Otokojuku fighter to die.
In the Paren Seiha he displays a sadistic personality disorder by viciously attacking Hien repeatedly, but he is actually a shy and gentle person despite his huge body and grim face. In the anime he wears an eyepatch.

From his first appearance to the Paren Seiha he had puffy eyelids and the face of a sarcastic senpai character and used cowardly tactics, but in the Tenchou Gorin his face was more slender and attractive.

In the end he is stabbed by Centaur's unicorn horn and dies. He was able to see through Gekkou's blindness.

However, he has also shown a deep compassionate and honorable side, like when he attacked a subordinate who tried to shoot Michelle while he was saving Togashi.
- He had an even match against Momo and his Shinki Fuukon, but the burden of his teammates being imprisoned prevented his Shinki Fuukon, turning it into a one sided match. After the ōendan of his classmates reawakens Momo, Gouki suggests they settle things with the Entou Kyouyutou. He is sure of a victory after he breaks Momo's katana, but Momo ties the katana back together with his hachimaki and uses it as a boomerang to attack from behind, dousing Gouki in flames.
- After the flame of Momo's Shinki Fuukon disappears, Hyoei Todo has a sniper shoot him with a tranqulizer bullet. Unaware of this, Gouki overwhelms Momo with his Senretsuken and goes to stab him with his katana, but his katana breaks on the Otokojuku Representative Successorship Proof pendant Jaki had given Momo and instead Momo's fist goes through Gouki's chest.

He then uses his personal taijutsu to fight and overwhelms J with his Binsakai Shousai, Soukaku Byoukou, and Soukaku Houchuusatsu, but J hits him on the crown of his head with his Flying Crash Megaton Punch, burying him up to his head in the ground. Because he abused their feelings during the fight his "brothers" were about to eat his head, but J had broken all their fangs and subsequently saved Gobalski's life. After the tournament ends he enrolls in Otokojuku and, along with Hakuhou and Pharaoh, acts as the comic relief. He has not cleaned his fundoshi in three years.
