He attends Tsujido High & when the Oni-baku transfers to his school, he quickly befriends them, initially for their fame.
To the Oni-baku's delight, he always has endless schemes to hook them up with girls. He offers to introduce them to Keiko & Mayumi, two delinquent girls who wants to hook up with the Oni-baku. He meets Eikichi on the train & picks a fight with Enoshima High students, not knowing that Eikichi's wig is stuck between the doors. He gets beaten down by the bullies to discover Eikichi's position. He later takes Eikichi to meet the girls, who flee upon seeing Eikichi's bald head.
He later tries to make it up to Eikichi & presents the Oni-baku with tickets to the Culture Festival at the Ferris School for Girls, known for it's easy girls. His ability to pick up girls at the festival is admired by the Oni-baku. He later offers to help Eikichi take down Machida, but is refused. His next scheme to help the Oni-baku get girls is the Valentine's Day Parade, but his cute animal themed car gets beaten by the Oni-baku's stolen Koenig Benz 500SL.
When the Kamakura Mad Dogs return to Tsujido, he gets beaten by Saejima, who manipulates him into betraying the Oni-baku & luring Eikichi into an ambush. As Eikichi gets ambushed by Saejima & his friends, he thinks back to his junior high days where he was bullied & attacks Saejima from behind with a shovel to save Eikichi. He is quickly beaten down, but allows Eikichi a chance to attack Saejima. He thanks Eikichi for later covering up his betraying & telling Ryuji that he helped Eikichi beat Saejima.
He later hears about the Oni-baku's plan to get laid with Itou Yui & her friends & invites himself, much to the Oni-baku's dismay. He & the Oni-baku Gumi compete for the new blonde girl, Kaoru & is the 2nd to be eliminated. He later finds out about Kaoru's secret from Kamata. Sometime later, he comes up with his next scheme & presents Eikichi tickets to the grand opening of Jaharama, promising lots of girls. During the Fumiya arc, he, along with Tsukai & Abe, stop the police for Ryuji to escape & rush to Eikichi's aid.
During the Okubo arc, he accompanies Eikichi to meet up with Otsupo of Kyokuto High, who warns them of Okubo. After finding out Eikichi's decision to give in to Okubo's threats, he & Saejima head off to confront Okubo & his men on their own, despite Eikichi's protest. They get beaten easily & are saved by Eikichi. The fight is postponed by Otsupo, who tells Okubo not to fight Eikichi when he is still injured. He & Eikichi later get ambushed by Okubo, who disregards Otsupo's words. He gets his fingers broken & held at knifepoint before Eikichi is able to defeat Okubo.
Sometime later, he is confronted by an old girlfriend, Mami, who tells him that she is pregnant. He goes to Eikichi for help, but realises the trouble he's in upon discovering Eikichi's hatred towards men who abandon their responsibility. To his horror, all of his friends offer him money for the baby, which is instantly spent by Mami. After Mami's father threatens to kill his family for getting involved with his daughter, he is saved by Eikichi & finally accepts responsibility, deciding to run away with Mami. As the Oni-baku Gumi step up to fight Mami's father's men, Mami tells him that she is not pregnant after all.
He shaves his head for all the trouble he caused the Oni-baku Gumi with Mami's father & gets moved up to 2nd year, while the Oni-baku held back. He watches the fight between Ryuji & his 1st year homeroom teacher, Minamino. During the Idaten gang arc, he arrives as backup with the rest of the Oni-baku Gumi during Eikichi's fight with Takezawa Akira. His role during the Midnight Angel arc is minimal, only visiting an injured Ryuji in hospital.
During this time, he runs into his friend, Tsunoda, who asks him to use his friendship with the Oni-baku to scare off Haramurata. His plan backfires when Haramurata's friend from the Kamakura Massacre Unit, Samehara, forces him to bring the Oni-baku to Samehara, or get beaten. With the Oni-baku nowhere to be found, he goes to the other Oni-baku Gumi members for help, who refuse & tell him to act like a man. He solves his problematic situation by asking his father for two mean dogs, of which he introduces to Samehara as Oni & Baku of the Oni-baku.
Sometime later, he settles down with Mami, who becomes his girlfriend. During their date, he is ridiculed for his Yamaha Jog & yearns for a 400cc bike. He is tricked by Saejima into buying a pink Kawasaki Zephyr, unknown to him that it was stolen from Katsuyuki. He tries to dispose of the cursed bike, without success & modifies it to make it unrecognisable after hearing a suggestion from Mami. He helps Katsuyuki & the Oni-baku Gumi attack Enoshima High, whom Katsuyuki suspects to be the thieves of his bike. The identity of his bike is finally revealed by Nakajo, to his horror. He later reluctantly follows Katsuyuki as he takes out his anger on random bystanders.
