Affiliation	Class D; Basketball Club
Occupation/Role	Student; basketball player
Status	Active student; returned after a three-week suspension 121

Background

Sudo was raised in a broken family. After his mother, a hostess, left home, he resolved to become strong; seeing his janitor father as submissive further fueled his rejection of weakness. In an environment of school bullying, he adopted a volatile, confrontational persona to ensure others would not target him. He gave up on academics early and focused his efforts on sport because of his exceptional physique. 67

Before enrolling at Advanced Nurturing High School, Sudo received an offer from a prestigious basketball school, but a violent incident caused the offer to be revoked. Sudo later maintained that both sides had been at fault and that the investigation unfairly relied on his prior record. 97 99

At Advanced Nurturing High School, he joins Class D and the Basketball Club. His goal of becoming a professional basketball player motivates him to seek academic improvement despite his weak foundation. 62 64

Appearance

Sudo is a tall, heavily built student with conspicuous red hair and an athletic build shaped by regular training. 62 66 121

• Flamboyant red hair that appears ready to “shoot skyward.” 121
• Muscular physique, noted by classmates during the swimming competition. 66
• Often appears in a wrinkled uniform after workouts, with sweat still on his forehead. 62
• After his suspension, his posture becomes more relaxed and solid, while his formerly impatient gaze appears subdued. 121

Personality

Initially, Sudo is hot-blooded, blunt, and easily provoked. He recognizes that he has a short temper and poor communication skills, which makes him reluctant to approach academically stronger classmates directly. 62 His aggression began as a defensive survival habit, but it repeatedly creates problems for both himself and Class D. 67 89

Despite this, Sudo is capable of gratitude, loyalty, and self-reflection. He pays Ayanokoji for preventing a fight with upperclassmen, asks for help organizing tutoring, and gradually learns to restrain himself during conflict. 62 64 Horikita’s detailed study notes become a turning point: Sudo recognizes her sincerity, apologizes for storming out, and recommits himself to studying. 67 72

Following his suspension, he becomes noticeably more patient and considerate. He acknowledges that his impulsiveness hurt the people who supported him, seeks to make amends, and values opportunities for improvement over immediate status. 99 121 122 124

Story Role / Major Arcs

Academic Improvement Arc

Sudo seeks help from Ayanokoji to organize more effective tutoring so he can improve academically and pursue professional basketball. He initially endures Horikita’s demanding teaching style, then storms out after she challenges his perseverance. 62 64

Horikita later gives him carefully prepared notes. Touched by her continued effort despite their argument, Sudo apologizes and resumes studying with renewed commitment. 67 72

Class C Assault Incident

Ryuen targets Sudo because of his violent reputation and his importance to the Basketball Club. Class C lures him to the Special Teaching Building, where a fight is staged to portray Sudo as the aggressor. 85 89

Class D mobilizes to find evidence, forms alliances, and offers a 500,000-point reward for reliable information. Although Horikita exposes inconsistencies in Class C’s account, Sudo’s prior violent record undermines the defense. 90 95 97

Sudo is suspended until summer vacation, Class D loses 30 class points, and he must pay each of the three injured Class C students 30,000 points. 98

Return and Reconciliation

After the ruling, Sudo apologizes to Class D and personally returns Ayanokoji’s spare key cards, admitting that he wants to change his behavior. 99

Following three weeks away from school, he returns more restrained and reflective. He invites Ayanokoji, Hirata, Yamauchi, Kushida, and Horikita to dinner to apologize and thank those who supported him. 121 122

Though barred from becoming an official starting player, Sudo accepts a substitute role on the Basketball Club. He chooses to value training, match experience, and future opportunities rather than immediate recognition. 123 124
