Background / History

Suzune enrolls at Advanced Nurturing University intending to catch up to her older brother, Student Council President Horikita Manabu. Her pursuit of his approval defines her early outlook and her determination to prove herself. 20

During the Club Orientation incident, Suzune reacts strongly to the suspected slander of Manabu and recruits Ayanokoji Kiyotaka to investigate Nanumo Miyabi. She pressures him into helping with a metal compass, reflecting her blunt, forceful approach to solving problems. 18

Manabu responds harshly when Suzune confronts him, ordering her to withdraw from Class D and striking her. Though devastated, Suzune refuses to abandon her goal of proving herself. She later learns through a recording that Manabu privately asked Kitagawa Kai to protect her, complicating her view of their relationship. 20 22

After Chabashira Sae explains that Suzune's placement in Class D stems from personal flaws rather than academic or physical shortcomings, Suzune begins confronting her poor social skills and inability to cooperate with others. 35 36

Appearance

Suzune is a tall, slender girl with long, straight black hair and a notably cold, composed presence. Her usual maroon school uniform and rigid posture reinforce her initially unapproachable image. 18 47 136

• Long, straight black hair. 18
• Tall stature and a slender frame. 18 118
• Sharp, cold expression and gaze. 18 59
• Often carries herself with an upright, disciplined posture. 47 59
• Wore her hair in a high ponytail during the Sports Festival. 170

Personality

Suzune is intelligent, proud, direct, and highly self-disciplined. Early in the story, she measures herself against Manabu and believes individual ability should be enough to overcome Class D's circumstances. Her lack of patience and empathy makes her an ineffective teacher despite her academic ability. 20 35 47

She is stubbornly independent and resists being treated as someone who needs protection. Even after learning of Manabu's request to Kitagawa, she insists that she can handle her own affairs. 22

Over time, Suzune becomes more willing to take responsibility for Class D, cooperate with classmates, and acknowledge emotional bonds. She remains blunt, but consciously tries to become more tactful and learns that people may act from malice rather than simple incompetence. 59 136 243 248

By the cruise-ship arc, Suzune reevaluates her fixation on elevating Class D to Class A. She decides that personal development and responsibility for her own future matter more than pursuing a class rank at any cost. 136
