Background / History

Suzune enrolled at Advanced Nurturing High School to follow the path of her older brother, Student Council President Horikita Manabu. She has admired him since childhood and measures her own worth against his accomplishments, though the siblings had not spoken for two years by the time she entered the school. 19 38

Her academic credentials are exceptional: she placed third across the entire grade on the entrance examination, and her interview was highly rated. Nevertheless, she was assigned to Class D because the school judges more than academic performance; Chabashira Sae identifies Suzune's lack of qualifications in other areas as the reason she belongs there. 23

Before enrollment, Suzune had avoided social connections since kindergarten. She saw friendship as fleeting and unnecessary, preferred reading alone, and initially treated Class D's failures as problems beneath her concern. 19

Appearance

Suzune is a petite, slender student with long black hair and clear, piercing eyes. She is usually seen in the school uniform with black knee-high or over-the-knee socks. 4 19 49

• Long black hair, often falling over her shoulders. 4 49
• Pale complexion and a composed, striking appearance. 49
• Wears the standard school uniform and black stockings. 4 19
• Her sharply angled eyebrows and cold gaze give her an intimidating impression. 44

Personality

Suzune is intensely proud, self-reliant, and focused on achievement. She initially considers socializing tedious and rejects overtures of friendship from both Kushida Kikyo and Ayanokoji Kiyotaka, believing she does not need anyone else. 19

Her confidence is undermined by her placement in Class D and by Manabu's harsh assessment of her shortcomings. Rather than abandoning her goal, she becomes determined to reach Class A and prove herself worthy of standing alongside her brother. 20 23

She is blunt to the point of alienating others. Even when trying to improve Class D, she dismisses classmates as useless, gives orders without tact, and struggles to understand why they resist her leadership. 25 26 31

Over time, Suzune becomes more pragmatic. She begins considering the value of her classmates, organizes tutoring for failing students, and adjusts her approach by appealing to Sudo Ken's dream of becoming a professional basketball player. 43 48 49
