Background / History

Horikita enters Advanced Nurturing High School as a Class D student. At the school entrance, she confronts Ayanokoji after noticing him looking at her, establishing her direct and confrontational manner. 1

Despite placing third in the grade on the entrance examination, Horikita is dissatisfied with her placement in Class D and demands an explanation from Chabashira. When told that academic scores are not the only criterion, she is unable to accept the answer. 11

Her desire to reach Class A is closely tied to her elder brother, Horikita Manabu. During the island exam, she admits that she wants to gain his acknowledgment. 15 72

Personality

Horikita is highly independent, blunt, and academically driven. After saving Sudo from expulsion, she makes clear that she acted for her own goal of reaching Class A rather than out of personal concern, and insists that she can rise through her own strength. 17 18

She is initially dismissive of cooperation, often rejecting classmates' attempts to involve her socially or strategically. Even when her popularity rises, she refuses invitations and maintains distance from Class D. 17 21

Her island-exam failure forces her to confront the limits of this outlook. After losing her key card and collapsing from illness, she acknowledges that having a companion might have allowed her to protect it, beginning to recognize the value of friends and teamwork. 63 72

Story Role / Major Arcs

Academic Crisis and Sudo's Expulsion

When Sudo fails English by two points, Horikita questions Chabashira about the consequences of expulsion and finds a way to purchase the missing points. Her intervention prevents Sudo's removal and the associated class-point penalty. 16 17

Although her actions greatly improve her standing in Class D, she rejects the gratitude and social attention that follow. Sudo becomes especially loyal to her and promises to listen to her going forward. 17 18

Sudo's Assault Case

Horikita helps investigate the case against Sudo and identifies Sakura as the witness. 24

She later joins Hirata in confronting the Class C students involved. Their threats of exposure and expulsion compel Class C to withdraw its complaint, resolving the incident without a deduction to Class D's points. 30 33

Uninhabited Island Special Exam

Horikita accepts the hazardous role of Class D leader after the class selects its base. 41

During the exam, she works with Ayanokoji to scout rival classes and coordinate Class D's strategy. As her illness worsens, she continues pushing herself to participate rather than withdrawing. 68 71

Ibuki steals Horikita's key card while she is washing at the river. Horikita pursues her, confronts her beneath a marked tree, and fights to recover the card, but collapses after being defeated. 61 62

Ayanokoji finds her unconscious and takes her for medical treatment. Class D subsequently uses a leader-change strategy involving Yukimura, while many classmates later believe that Horikita orchestrated the successful plan. 63 71 72 75
