Background / History

Suzune is assigned to Class D, a placement she openly contests after Chabashira Sae characterizes the class as the school’s collection of “defective products.” She refuses to accept that Class D cannot surpass Class A and makes clear that she intends to rise through the rankings. Her determination is connected to her older brother, Student Council President Horikita Manabu, whose footsteps she came to the school to follow. 21 22 28

Manabu initially treats Suzune as an embarrassment and pressures her to leave the school, but she refuses to drop out. When Uesugi Gen threatens to reveal Suzune’s presence to Nagumo Miyabi, Manabu is forced to abandon the confrontation and asks Suzune to return to her dormitory. 28

Following the midterm crisis in which three Class D students face expulsion, Suzune proposes using personal points to restore their scores. She ultimately accepts Uesugi’s open-ended condition for the next special exam in exchange for saving all three students, prioritizing Class D’s future manpower over her personal dislike of them. 31 32

Appearance

Suzune is a cold-looking beauty with long, straight black hair and a sharp, guarded gaze. Her usual expression and bearing project an unapproachable, self-contained demeanor. 21 27

• Long black hair. 21 27
• Sharp gaze and a “don’t talk to me” aura. 21
• Often maintains a cold or expressionless face, though anger can break through it. 21 35 36
• Wears black over-the-knee socks with her school uniform. 21

Personality

Suzune is intensely ambitious, disciplined, and unwilling to accept failure. Though she initially considers Class D’s advancement unrealistic, she refuses to abandon her goal of reaching Class A and repeatedly acts to protect the class’s competitive potential. 22 32 48

She is blunt toward classmates she considers irresponsible. During the expulsion crisis, she criticizes Class D for violating rules and refuses to excuse their failures; similarly, she loses patience with Yamauchi Haruki’s boasts and decisively exposes his inability to back them up. 31 33 35

Despite her detached manner, Suzune honors her agreements. She accepts Uesugi’s harsh terms to preserve Class D’s members and later agrees to transfer 150 points’ worth of supplies on the island because she signed the contract. 32 48
