Story Role / Major Arcs

Bus Journey

When Sakura Airi struggles to untangle her camera strap, Ike laughs and draws attention to the risk of damaging the expensive camera. His comment contributes to Airi's embarrassment before Orikasa resolves the problem. 1

Opening Ceremony and Early Class D Life

At the opening ceremony, Ike repeatedly yawns and appears unfocused, reflecting Class D's lack of discipline. 2 In the classroom, he brags animatedly to Yamauchi and introduces himself by enthusiastically discussing his preferred type of girl. 3

After receiving 100,000 points, Ike immediately begins planning where to splurge with Yamauchi. 3

Lunchbox Incident

Ike is among the classmates who turn to stare after Hasebe Haruka teases Sakura Airi about giving Orikasa Yuu a handmade lunchbox. 6

Class D Betting Incident

Ike joins Yamauchi and Sudou in discussing the girls' bodies, then participates in Sotomura Hideo's point-based betting pool on Class D girls' chest-size rankings. 7 Hirata Yosuke orders Ike and the others to stop, arguing that the class needs basic respect; Ike returns to his seat while still grumbling. 7

Swimming Class

Ike is impressed by the school's indoor swimming complex and complains alongside Yamauchi when Sakura and Hasebe remain in the stands rather than joining the pool. 8 In the changing room, he is stunned by Orikasa's unusually balanced, powerful physique and calls him a “monster.” 8

Trivia
