Story Role / Major Arcs

Early Class D Conflicts

Sudo refuses to participate in Class D’s self-introductions and later leaves when Hirata discusses a possible school-wide assessment. His lack of discipline, absences, and confrontational behavior contribute to Class D’s poor standing. 2 7 8 16

He also confronts three second-year students outside the convenience store and kicks over a trash can after they leave, establishing the reputation that later makes accusations against him believable. 4 42

Midterm Study Group

After Class D learns that failing students may be expelled, Sudo becomes one of the class’s most vulnerable students academically. Horikita’s hostile teaching approach leads him to quit her study group temporarily, but he later returns and studies seriously. 16 22 29

Sudo passes the midterm examination and thanks Horikita for helping him. During that conversation, he realizes that he has fallen for her. 35

Class C Assault Case

Sudo is accused of assaulting a Class C Basketball Club member. He maintains that he acted in self-defense after Komiya, Ishizaki, and another Class C student attacked him for refusing to leave the Basketball Club. 41 42

The case is complicated by Sudo’s reputation: his classmates and circulating rumors readily assume that he is capable of violence. 42 45 Konoe obtains surveillance footage indicating that Class C deliberately injured Ishizaki further to inflate the apparent severity of the incident. 44
