Horikita Suzune

Biodata

Background and History

Suzune enrolls at Advanced Nurturing High School to follow in the footsteps of her older brother, Student Council President Horikita Manabu. She initially keeps to herself: during Class D’s introductions, she gives only her name, and the school judges her an extreme individualist who lacks teamwork and loyalty to her class 3 4 6.

After a task prompts her to question teacher Sae Chabashira about the next month’s points, Suzune notices that the answer is evasive. She spends 50 points in her Perfect Life System’s shop on information explaining the school’s class rankings and the link between class points and monthly payments. Determined to overturn the school’s assessment, she chooses to pursue Class A by raising Class D rather than transferring alone 3 4 8.

Suzune takes her findings to Manabu, who praises her deductions but challenges her reliance on Nangong Cheng’s hints. A later conversation with Manabu and Cheng helps her recognize that she has been imitating her brother. She asks Cheng to teach her how to earn recognition as herself, and he assigns her to observe and report on her classmates 6 7 19 25.

She gradually takes on practical responsibilities: coordinating tutoring for Class D’s girls, helping Sakura Airi study, and building a connection with Class C reader Shiina Hiyori. At a gathering for the girls, she offers academic help and makes a direct effort to befriend Kikyo Kushida 34 35 39 41 42 47.

Appearance

Suzune has long, straight black hair and is often seen reading. Her reserved manner initially makes her difficult for classmates to approach 13 24.

• She regularly visits the library and sets herself weekly reading targets 35.
• She is not a skilled singer; her awkward karaoke duet helps classmates see a less forbidding side of her 42.

Personality

Suzune is blunt, disciplined, and academically capable, but initially struggles with apologies, small talk, and cooperation. Her confidence falters around Manabu, whose approval matters deeply to her 4 6 19.

She becomes more willing to adapt without abandoning her judgment. She studies Cheng’s methods despite disapproving of some of his behavior, defends Kei Karuizawa from blame after one of his pranks, and apologizes to Kushida for an earlier harsh remark 31 32 43.
