Horikita Suzune

Biodata

Appearance

Horikita is a long-haired girl with a cold, ethereal expression and a notably composed presence. Her hair reaches her waist. 15 19

• Fair, slender hands and long hair. 15 19
• Usually maintains an icy, emotionless gaze and tone even under pressure. 15 23
• Her composure visibly breaks only in extreme situations, such as Ryuen’s intimidation and the stadium riot. 15 34

Personality

Horikita is highly independent, direct, and intolerant of recklessness. She prioritizes consequences over emotional reactions, repeatedly stopping Class D from escalating conflicts that could cost the class points or lead to expulsions. 15

She is also principled and protective. Despite her hostile history with Kushida, she intervenes to protect her from Ibuki and Ishizaki, explaining that she will not stand by when someone is in danger. 19 Her concern extends to classmates such as Sudo, Karuizawa, and Hirata, whose unusual behavior she investigates rather than dismisses. 10 29 30

Later events make Horikita more cautious. The riot exposes the limits of relying on others’ goodwill, while Ayanokoji’s advice leads her to question whether her growing detachment is necessary for Class D. 34 48

Abilities & Skills

Analysis and Rule Awareness

Horikita carefully assesses situations through school rules, evidence, and potential consequences.

• Identifies Sakura Airi’s withdrawn behavior as evidence that she may have witnessed Sudo’s alleged assault. 10
• Prevents Class D from attacking Ryuen’s group by pointing out that Ryuen had not clearly trespassed or committed an actionable assault. 15
• Warns that footage, class-point deductions, and disciplinary consequences could turn Rinya’s actions into a liability for Class D. 21
• Notices suspicious links between Hirata’s resignation, the cancelled fund plan, and Karuizawa’s sudden absence. 29
• Detects Karuizawa’s prolonged crying and presses her about possible trouble involving Hirata. 30

Physical Conditioning and Combat

Horikita has superior physical training and can fight defensively when necessary.

• Matches Ibuki Mio’s kick and holds her position long enough to tell Kushida to escape. 19
• Attempts a full-force counterattack against Ryuen after being cornered. 15
• Knocks out several attackers during the stadium riot while trying to protect endangered students. 34
• Is outmatched by Ryuen, who blocks her kick and throws her to the ground. 15
• Becomes exhausted and severely injured when overwhelmed by multiple out-of-control students during the riot. 34

Crisis Intervention

Horikita is willing to place herself between others and danger.

• Stops Sudo from throwing a punch at Ryuen’s group and explains why restraint protects the class. 15
• Intervenes when Ibuki attacks Kushida, despite Kushida’s hostility toward her. 19
• Calls for emergency assistance when Ishizaki’s use of a stun baton threatens Ibuki. 19
• Continues trying to restrain violent students during the stadium riot rather than immediately retreating. 34

Relationships

• Ayanokoji Kiyotaka — Classmate and uneasy ally. Horikita challenges him over suspected score manipulation, later relies on his judgment during several mysteries, and receives his support for her changed outlook after the riot. 7 21 29 48
• Horikita Manabu — Her older brother and the student council president. Their relationship is strained; an alleyway confrontation leaves Suzune distressed before Ayanokoji intervenes. 7
• Rinya — Classmate whom she distrusts and repeatedly confronts over his secretive, potentially damaging actions. She tries to reimburse half of Sudo’s saved-exam cost, later withholds Rinya’s combat abilities from others despite suspecting his involvement in multiple incidents. 8 20 21
• Kushida Kikyo — Former middle-school acquaintance and personal rival. Horikita nevertheless protects Kushida from Ibuki and Ishizaki, and later helps her escape pressure to lead Hirata’s fund-support project. 19 22 31
• Sudo Ken — Classmate whose impulsiveness she regularly restrains. She helps resolve his assault case but firmly rejects his unwanted interference and romantic attachment. 13 15 23
• Ibuki Mio — Rival from Class C. Horikita fights her while protecting Kushida, then shows concern for her safety when Ishizaki’s violence escalates. 19 20
• Karuizawa Kei — Classmate whose emotional distress Horikita notices and investigates in connection with Hirata’s resignation. 29 30
• Hirata Yosuke — Class D’s representative. Horikita grows suspicious when he abruptly closes the Study Fund Support Plan and resigns. 29
• Koenji Rokusuke — Horikita provokes him accidentally while helping Kushida evade attention; she later accepts responsibility and apologizes. 22 23
