Igano Kabamaru (伊賀野カバ丸) is a Japanese manga series written and illustrated by Yū Azuki. The eponymous protagonist is a naive young ninja from the Iga province called Kagemaru (absolute shadow), nicknamed Kabamaru (hippo's mouth) for his insatiable appetite. After the death of his strict grandfather and ninja sensei, Kabamaru moves to Tokyo with one of his grandfather's acquaintances. The plot deals mainly with Kabamaru adjusting to an urban lifestyle after spending a childhood in the mountains, him developing feelings for his guardian's granddaughter, and how he finds himself caught up in the rivalry between two private schools.

Igano Kabamaru has been adapted to anime television and film.



Kabamaru was orphaned at a young age and raised by his grandfather Saizō Igano (伊賀野才蔵, Igano Saizō), who trained Kabamaru and another young orphan, Hayate Kirino (霧野疾風, Kirino Hayate) in the ninja arts. While Saizō took care of the two children, he was also a very strict teacher, punishing incompetence or disobedience with physical violence. The two children eventually tried to escape, with Hayate suggesting they split up. Kabamaru was recaptured, but he refused to reveal his friend's whereabouts to Saizō. Hayate watched, hidden, and finally made the decision to take advantage of the opportunity and flee. This choice haunted him ever since.

Kabamaru is in his adolescence when his grandfather dies. At his funeral, he meets an elderly lady called Ran Ookubo (大久保蘭, Ōkubo Ran). Saizō was Ran's first love and he had asked her in a letter to take care of his grandson when he died. Kabamaru follows Ran back to Tokyo, where he is to stay in her house and attend Kin'gyoku (Golden Rules) School, of which Ran is the headmistress.

On arriving, Kabamaru meets Mai Ookubo (大久保麻衣, Ōkubo Mai), Ran's granddaughter, who has lived with her ever since the death of her parents. Kabamaru instantly takes a liking to Mai, but she finds his coarse manners and endless appetite embarrassing and repulsive. These feelings are shared by Kingyoku's Vice Principal, who nevertheless tolerates Kabamaru's antics out of loyalty and a secret infatuation with Ran. Ran herself is blinded by Kabamaru's striking resemblance to Saizō and sees everything Kabamaru does as charming.

Soon after arriving in school, Kabamaru inadvertently saves some students from being bullied by an older student called Shirakawa. Shirakawa is a member in a secret student society which includes in its ranks Kaoru Nanokusa (野々草かおる, Nanokusa Kaoru), the beautiful head of the student council. Its real leader, however, is Shizune Mejiro (目白沈寝, Mejiro Shizune), a rich and popular bishōnen student whose weak facade actually conceals a powerful whip-wielding fighter. All the girls have a crush on him, including Mai. Shizune's gang is intent on antagonizing another school called Ōgyoku (Topaz Rules). However, negative feelings of varying intensity exist between most students of both schools.

The rivalryEdit

Kin'gyoku School and Ōgyoku School have been bitter rivals for almost half a century and compete fiercely in everything, from athletic competitions to which school has the most expensive clock tower. The reason for this is twofold: first, the rivalry between Ran and Ōgyoku School's headmistress, Sū Matsuno. Both Ran and Sū used to be best friends until they met Saizō and fell in love with him. Saizō secretly went on excursions with both of them, desiring the food baskets the girls brought to him. When the truth was revealed, the girls asked Saizō to choose one of them but he turned them both down, as by ninja tradition he could only marry a ninja. Unable to be angry at Saizō, the two girls turned against each other.

The second reason is the rivalry between the wealthy and influential families of Shizune Mejiro and Shuu Maejima (前島秀, Maejima Shū), head of the Ōgyoku student council. The two families vie for control over the whole of Japan, and their children have moved that conflict onto the school grounds.

The long distance relayEdit

Shizune initially considers Kabamaru an interfering pest, so he orders him dealt with. After Shirakawa fails to crush Kabamaru with force and Kaoru fails to charm him with her beauty, Shizune decides to win him over, bribing him with food and particularly yakisoba noodles, Kabamaru's favourite delicacy.

Shizune, aware of Kabamaru's physical prowess, convinces him to participate in the annual inter-school long distance relay race. At the day of the race Kabamaru manages to take the lead and almost wins, but a few metres before the finish line he is startled by a shuriken thrown at him from an unseen Hayate, who is now unwillingly in the custody and employ of Sū. Kabamaru realizes that Hayate is in the city and starts looking for him, excited at the thought of reuniting with his childhood friend.

The rivalry escalatesEdit

After some Ōgyoku students are caught spying on the premises of Kin'gyoku, Shizune has Kabamaru and Kaoru attend a party hosted by Ōgyoku in celebration of their victory at the long distance relay in order to spy on Maejima. During the night, Kabamaru and Kaoru infiltrate the Ōgyoku dormitories, but only discover that Maejima has a crush on Mai and has written her a love letter. This infuriates Kabamaru, who attacks Maejima and flees, accidentally dropping the love letter in Sū's office.

A few days later, Maejima receives an invitation to a date by a person he assumes to be Mai. To his dismay, he actually meets with a flirtatious Sū, who has read Maejima's love letter and thinks it was meant for her. Maejima comes to the mistaken conclusion that Kabamaru is the mastermind behind the dormitory attack and has deliberately created the love letter misunderstanding to mock him. Later that night, he disguises himself and attacks Kabamaru with a bat but ends up injuring Shizune in the arm instead. He also begins training students in martial arts to act as his bodyguards against future assaults.

Shizune learns about Maejima's actions and considers them a preparation for an all-out attack against Kin'gyoku. He asks Kabamaru to train him and his friends in the ninja arts so they can fight back, but Kabamaru's popularity and Ran's enthusiasm over his involvement lead to the entire school volunteering for ninja training in the Iga mountains, ruining Shizune's covert plans.

Hayate, who has been ordered to put Kabamaru out of commission, is unwilling to harm him directly, so he anonymously contacts Shirakawa and manipulates his dislike for Kabamaru. He gives Shirakawa drugged candy and instructs him to deliver them to Shizune, both knowing that Kabamaru is certain to devour them first. Shirakawa is then supposed to attack the sleeping Kabamaru. The plan almost works, but Kabamaru offers one candy to Ran, who later faints in the middle of the road. Hayate rescues her from being run over, which leaves him conflicted between the loyalty to his old friend Kabamaru and the grateful Ran on one side and his duty to his employer, Mrs. Matsuno, on the other.

Excursion in the Iga MountainsEdit

Kin'gyoku School goes for fitness training in Kabamaru's homeland, the Iga mountains. Hayate follows them, spying for Sū. They camp in an old abandoned Buddhist temple which has a statue that, according to Kabamaru, comes alive during the night. Indeed, while everybody sleeps, Shizune sees the statue moving. Ran determines from various clues that the statue is, in fact, Saizō, meaning that he is still alive. She keeps this to herself, certain that Saizō has his reasons.

A few days later, Kabamaru is taking a nighttime stroll when he is suddenly challenged by shuriken and throwing knives. He dodges all of them and Hayate finally shows himself to him. In the conversation that follows, Hayate reveals to Kabamaru that he essentially used him in order to escape from Saizō and leave his past in the mountains behind. He disguises his guilt and self-loathing by urging Kabamaru to forget their friendship and stay in the mountains. He then escapes in the darkness, leaving behind an upset Kabamaru, who nevertheless still considers Hayate his friend.

The following day, Kabamaru instructs everyone to stay indoors because a blizzard is imminent. Regardless, Shizune and his clique head outside to train and are later joined by Ran and Mai. A snowstorm indeed comes, and Ran and Mai are separated from the group and from each other. Ran is rescued by Saizō, who reveals himself to her and later returns her to the temple, but Mai is rescued by Kabamaru, who takes care of her in a nearby shack while the storm blows over. After this incident Mai grows to appreciate Kabamaru more.

The final confrontationEdit

In the meantime, Maejima extends his control over the student councils of other schools, forming secret "assault squads" there. He also tries to exert control over the Kantō Elite School Union, seeking to dissolve it, expelling Kin'gyoku from it, and form a new Union controlled by Ōgyoku. Finally, he enlists members of criminal gangs to do his dirty work. Shizune learns about all this but is not too concerned, until Maejima challenges him to a one-on-one motorbike race after realizing Mai is in love with Shizune. Kabamaru secretly frustrates Maejima's attempts to cheat and Shizune emerges victorious.

This event makes Shizune take Maejima seriously and he resumes training his gang. When the rumor of Kin'gyoku's puppet master surfaces, the vice principal immediately suspects Kabamaru. Mai is skeptical and investigates further. She realizes that Shizune is the puppet master and is emotionally distressed but is convinced that Shizune is acting on behalf of the Kin'gyoku and is still very much in love with him. Soon after, Maejima succeeds in dissolving the Kantō Elite School Union, effectively canceling the inter-school baseball championship. The leader of the Kin'gyoku Baseball Team, Rui Tonou, visits Maejima to ask him to restart the championship, but Maejima thinks he is a spy and has him viciously beaten up. This infuriates Shizune, who now plans to attack Ōgyoku rather than defend against it.

Shizune enlists Kabamaru to help him in the fight against Ōgyoku. Mai overhears the conversation and fearing for Shizune's safety, tries to prevent the conflict. Meanwhile, Sū forces Hayate to battle Kabamaru, holding over his head how she's been taking care of him for the last 10 years and telling him that she'll let him go if he defeats Kabamaru. While Hayate has some qualms about fighting his friend, he also believes this will give him closure, letting him forget his haunting memories and start over. Mai fails to stop Kabamaru and Shizune, then she visits Ōgyoku School to personally talk to Maejima and ask him to stop... but Maejima's goons mistake her as Shizune's accomplice and capture her. They also attack and severely injure Shirakawa, who had gone there to give Maejima a formal "declaration of war" coming from Shizune. Maejima talks to Mai, but he refuses to believe that she isn't there out of her own will and keeps her hostage. In the meantime, Hayate intends to use Mai's kidnapping to anger Kabamaru into fighting him.

News of Mai's kidnapping and Shirakawa's injury reach Shizune, along with a one-on-one challenge from Maejima at the docks. This time, both cheat by bringing their gangs with them and an all-out confrontation between the students and staff of the two schools ensues. This is cut short when Hayate challenges Kabamaru, revealing himself as Mai's kidnapper.

Kabamaru's rage temporarily overcomes him, and they begin fighting. Kabamaru's anger soon fades, however, and his obvious distress over fighting his best friend reaches out to Hayate, who stops his attack in the last minute. Kabamaru instinctively counterattacks, injuring Hayate in the shoulder and causing him to fall in the water.

Just as everyone thinks Hayate has drowned, he emerges from the water in the arms of the Buddhist statue from the temple. The statue removes its disguise and reveals himself as the chef of the yakisoba restaurant Kabamaru has been visiting during the entire series. He then removes this disguise as well to reveal the ugly old man Kabamaru recognizes as his grandfather Saizō. Finally, he reveals that this is also a disguise he had been using around Kabamaru, discarding it to reveal his much handsomer true self. Saizō explains that he faked his death to introduce Kabamaru to the second stage of ninja training and the responsibilities of an adult. Hayate and Kabamaru, now reconciled, decide to return with Saizō to the mountains to continue their training, but not before Mai expresses her newfound feelings to Kabamaru and they promise to meet again.


The conventional storyline ends on the second to last episode. The series finale is a self-parody in which the characters gather to celebrate the conclusion of the story, only to be interrupted by The Author, a "cameo" of Yu Azuki. The Author reminds them that they still have to play the big baseball game between Kin'gyoku and Ōgyoku. The action immediately warps to the baseball field and a surreal match ensues, featuring ninja baseball techniques, Nazi and Native American baseball players and a battle between the mechas of the Kin'gyoku Vice Principal and Maejima (Gojira and King Kong respectively.)

This fight is cut short by Saizō in the guise of the Buddhist statue, who spirits the mecha away and commands the school rivalry ended before departing in a flying saucer. All this is a ninja illusion, which fools even Kabamaru and Hayate. This angers Saizō, and the series ends with him chasing his two students, berating them for their incompetence.





The anime series was produced by Group TAC and Toho. The 24 episodes were broadcast in Japan by Nippon Television between October 20, 1983, and March 29, 1984, every Thursday from 19:00 to 19:30.[citation needed]

The plot centers around a five-part competition between Kabamaru representing Kin'gyoku School, and Hayate representing Ōgyoku School. The five events are falling from a height on a balloon (Kabamaru wins), swimming (Hayate wins), throwing shuriken while horseriding (Kabamaru wins), food eating contest (Hayate wins - Kabamaru is disqualified because he missed an olive) and remaining on the roof of a car driven by a student of the opponent school (Kabamaru wins after being promised 1,000 plates of yakisoba noodles by Shijune).

In Pop CultureEdit

  • The song "Igano Koiuta" has been sampled in the 12os pithikos song "Σε ευχαριστω (thank you)".
  • Kabamaru makes a cameo in the Greek show "Ουκ αν λαβεις παρα του μη εχοντος", as a guest star on The God Boat.
  • Kabamaru's likeness is compared to popular Greek actor Στάθης Ψάλτης.
