Appearance

Personality

Suzune begins her school life intensely independent, disciplined, and dismissive of the school’s lax atmosphere. She initially regards friendship as unnecessary, sees students from other classes as future rivals, and struggles to accept help without suspecting an ulterior motive. 35 60 125

Her greatest source of motivation is her older brother, Horikita Manabu. She models her conduct after him and is determined to prove that she can reach Class A, though his expectations initially make her anxious and insecure. 50 78 131

Despite her bluntness, Suzune is earnest and principled. She refuses to spread Kushida Kikyo’s secret, remains composed when pressured, and is willing to stake her own future in pursuit of her goals. 186 252

Over time, she becomes more receptive to cooperation and companionship. Her work with Hashiba Hikaru, Student Council duties, and leadership responsibilities gradually force her to consider other people’s circumstances rather than relying solely on individual competence. 145 207 504

Background

Suzune entered Tokyo Metropolitan Advanced Nurturing High School in Class 1-D. The school’s perceived laxness immediately frustrated her, and she approached student life with the same self-discipline she associated with her brother. 35

Horikita Manabu believed that Suzune’s personal flaws were obstructing her potential and asked Hashiba Hikaru to assist her development. Suzune initially resisted the arrangement but accepted it because she wanted to prove herself to Manabu and reach Class A. 28 41

Her early determination to surpass Manabu made her treat peers as obstacles or assets rather than friends. This isolation became a recurring weakness: she possessed ability and drive, but lacked the interpersonal understanding needed to lead a class effectively. 78 125 131

Story Role and Major Arcs

Sudo Deliberation

Suzune becomes Class D’s leading representative during the case against Sudo Ken. After refining her argument with Hashiba’s input, she uses convenience-store surveillance footage to expose Ishizaki and Komiya’s false injury claims. Manabu rules Sudo not guilty and suspends the two accusers for lying. 51 56

Uninhabited Island and Sports Festival

During the Uninhabited Island Exam, Suzune falls ill but recovers after taking herbal medicine prepared by Hashiba. Rather than rest, she scouts other classes’ camps for intelligence. 93 94

At the Sports Festival, Kinoshita Minori intentionally causes Suzune to fall during the obstacle race. Suzune recognizes that someone may have leaked her event information, later confirms Kushida’s involvement through the Cavalry Battle, and confronts her over the betrayal. 164 167 185 186

Suzune proposes a wager: if she wins the next Special Exam, Kushida must stop targeting her; if she loses, Suzune will drop out. 186

Twenty-Million-Point Plan

After declaring her goal of reaching Class A through Private Points, Suzune cooperates with Hashiba on the Sudoku Plan. She acts as his assistant, records challenge activity, helps establish the club, and gradually accepts him as an important partner. 143 145

The plan changes Suzune’s priorities: while she still competes for her class in the Sports Festival, she becomes focused on building a personal reserve of Private Points sufficient for a class transfer. 150

Student Council and Drama Club

Suzune decides to join the Student Council after Manabu advises her to work for her own growth rather than merely seek his approval. 195

She is assigned Club Management Department work to improve her social skills, though her blunt manner initially creates friction with club leaders. 207

When Drama Club president Sakurami Ryoko demands that Suzune produce a replacement script within six days or face impeachment proceedings, Suzune accepts the challenge. Her completed script ultimately passes with twelve of fifteen executive votes. 225 242 243

Relationship with Hashiba Hikaru

Suzune’s relationship with Hashiba develops from reluctant cooperation into reliance and affection. She begins calling him her companion, seeks his support in personal and Student Council matters, and eventually confronts her feelings directly. 222 226 244

During the Forest School period, Suzune confesses her love to Hashiba. The two become an official couple after sharing their first embrace. 296 297

She later plans dates herself, purchases Hashiba a bracelet, and studies how partners can improve their relationship. 417 418 421

Disciplinary Committee Leadership

Hashiba appoints Suzune as Chairperson of the newly created Disciplinary Committee. Her uncompromising personality suits the position, and her work earns increasing recognition among students. 374 376

She conducts recruitment interviews, prioritizing candidates’ competence and suitability for demanding committee duties. 455 456

Transfer to Class A

With roughly four million Private Points of her own, Suzune receives twenty million points from Manabu as an investment in her future and accepts his support. 406

She announces her transfer to Class A, where students welcome her for her academic ability and athletic potential. Her application is later approved, and her profile is updated to Class 2-A. 411 435

Uninhabited Island Strategy

For a later Uninhabited Island Exam, Suzune proposes intensive stamina training for weaker students and mixed-gender teams led by stronger members. Shiina Hiyori points out that Suzune’s plan initially overlooks interpersonal compatibility among team members, highlighting a remaining gap in Suzune’s social judgment. 503 504

Relationships

• Horikita Manabu — Her older brother and lifelong benchmark. Their relationship begins under the pressure of his high expectations, but he later acknowledges her growth and finances her class-transfer plan. 28 131 406
• Hashiba Hikaru — Initially Manabu’s chosen helper and Suzune’s creditor; later her Sudoku Plan partner, trusted companion, and boyfriend. 78 145 296 297
• Kushida Kikyo — Former middle-school acquaintance and persistent adversary. Kushida targets Suzune to protect her past, leaks information that endangers her during the Sports Festival, and becomes bound to Suzune through their Special Exam wager. 186
• Ichinose Honami — Hashiba’s official girlfriend and Suzune’s Class A classmate after the transfer. Their interactions are strained by their shared connection to Hashiba, though they agree to get along. 411
