Background / History

At the start of the school year, Horikita is an isolated Class D student who speaks to no one, sits with rigidly straight posture, and seeks to become the class's leader despite lacking the ability to manage the group alone. 1

Gu Heng approaches her first because she is the only classmate he expects to question the school's rules rather than recklessly spend her points. Though skeptical of his warning, she investigates his reasoning and agrees to observe Class D with him. 1 2

Her early cooperation with Gu is strained by his habit of reducing classmates to functions and risks. Horikita objects to his methods, but repeatedly recognizes the accuracy of his judgments—particularly his assessments of Sudou, Hirata, and Kushida. 4 17 22

Following Class D's second-place finish on the Uninhabited Island, Horikita continues developing its systems of recorded responsibility, restricted information, and defined public authority. During the Identity Exam and the subsequent Sports Festival preparations, she protects Class D's shared records from unauthorized changes while taking responsibility for the class's public statements. 115 117 133

As the Sports Festival's submission process tests whether Class D can operate without Gu Heng's direct control, Horikita leads the class through its first proposal meeting in his absence and turns the vacant representative role into a position requiring explicit acceptance of authority, deadline, and refusal conditions. She subsequently volunteers as Class D's official representative, gaining school-recognized authority to submit plans and make final decisions while Gu remains limited to review. 181 182

Horikita's later decisions establish that Class D's plans cannot override personal confirmation. She rejects Gu's statistically optimal recommendation when it would exceed Sudou's stated limits, accepts reduced projected results rather than overburden him, and requires future recommendations to state their worst possible consequence. 186 187

Appearance

Horikita is a short-haired girl with a cold expression and an exceptionally straight posture, described as sitting “like a ruler planted upright.” 1

• Short hair. 1
• Habitually cold, guarded expression. 1 2
• Rigidly upright posture that reinforces her authoritative presence. 1
• Maintains a composed, stern demeanor even when facing confrontation or public pressure. 24 74 132

Personality

Horikita is proud, analytical, and intensely competitive. She wants to lead Class D herself and initially equates leadership with retaining complete control, making her resistant to delegation or being publicly corrected. 1 21 22

She strongly rejects Gu Heng's language of treating people as “tools” or “price tags,” preferring to frame classmates through ability, responsibility, and resolve. Even so, she gradually accepts that Class D cannot function through individual control alone. 17 22

Her leadership is stern rather than conciliatory. Horikita is willing to record misconduct, impose consequences, and make unpopular calls when she believes they are necessary; however, she learns to pair that discipline with clearer systems, shared responsibility, and respect for classmates' privacy. 24 37 45 55

Horikita increasingly distinguishes between responsibility for a public position and control over every internal decision. She will answer for Class D's official wording and submissions, but refuses to expose private records, individual performance, or unconfirmed conclusions merely to satisfy outside pressure. 74 133 135 136

After becoming Class D's official submitter, Horikita develops a more independent form of authority. She accepts verifiable advice from Gu Heng and others, but rejects unsupported suggestions and refuses to treat his recommendations as automatic orders. 182 186

Though she acknowledges that she may pressure classmates in pursuit of victory, Horikita recognizes that pressure cannot be converted into official confirmation. She prioritizes documented consent, stated workload limits, and ownership of consequences over an arrangement that is merely optimal on paper. 178 186

Abilities & Skills

Leadership and Command

Horikita serves as Class D's visible leader, giving the class a public center while Gu Heng handles strategy and Hirata mediates between members. 21 22

• Collects students' physical conditions, academic strengths, and camping experience before the special exam. 21
• Holds the front line of Class D's command structure while allowing others to manage resources, assignments, and communication. 21 38
• Organizes the rescue response when three Class D students go missing during the island exam. 44
• Reorganizes rotations and assignments after Tonomura falls ill. 55
• Makes the final move to Class D's eastern public confirmation point with limited time remaining. 79
• Establishes Sports Festival registration so that physical events, logistical support, and substitute roles can be chosen simultaneously rather than through a pressuring registration order. 117
• Divides Sports Festival duties with Hirata and Sudou while deliberately excluding Gu Heng from direct event organization to encourage broader class participation. 115
• Directs Class D's careful review of the Sports Festival notice rather than allowing the class to draw conclusions before its official modules are confirmed. 136
• Keeps Class D's first proposal meeting moving without Gu Heng, requiring the class to review each exchange detail rather than wait for a central organizer to decide for them. 181
• Volunteers for the vacant representative role and becomes Class D's official submitter, with authority to make final decisions on its plan. 182
• Submits Class D's first accepted plan using eight classmates' confirmations while removing an arrangement that lacked sufficient consent. 182
• Rejects an optimal but non-consensual event allocation for Sudou, distributing the Strength Event among four members despite the lower projected result. 186
• Personally submits a relay-handoff adjustment that reduces Class C's marking risk without changing participants or increasing Sudou's burden. 187

Rule Enforcement and Records

Horikita uses written records to make Class D's rules tangible and enforceable rather than merely symbolic. 24 25

• Records Sudou's escalation during classroom conflicts and warns him that further misconduct will be formally noted. 24
• Maintains a notebook and later a record board for warnings, duty changes, absences, and violations. 24 37 38
• Separates “temporary slowdown,” “failure to report in advance,” and “voluntary adjustment” in her records during the island exam. 37
• Enforces base-boundary restrictions and centralized handovers when Hirata's duty roster disappears. 53
• Locks save permissions for the D-CLASS-REPLY record after the Identity Exam settlement and establishes separate rules for public notes and personal results. 115
• Separates Class D's public status and scope, internal training reviews and personal times, and official school event results into distinct records during Sports Festival preparations. 135
• Requires prospective representatives to review the role's authority, deadline, and refusal conditions before accepting the position. 181
• Publishes her own confirmation records to establish that she is an independent submitter rather than Gu Heng's stand-in. 182
• Preserves an anonymous warning in the risk file while excluding it from the official plan because its authorship and claims remain unverified. 182
• Records rejected ideas as unadopted proposals rather than allowing them to be mistaken for executable orders. 186
• Establishes a mandatory worst-case-consequence field for every future recommendation. 186

Analysis and Operational Coordination

Horikita can assess evidence, apply rules to evolving situations, and turn strategic decisions into practical instructions. 11 52 55

• Reconstructs Sudou's altercation by reviewing camera coverage, blind spots, witness positions, and the teacher's viewing angle. 11 12
• Helps establish boundaries on Kushida's information-gathering role after Kushida presents a hypothetical arrangement as nearly decided. 30
• Distributes partial false information during Class D's operation to identify the information leak without exposing the actual leader line. 62
• Uses a structured process for medical-supply decisions: Hirata verifies conditions, Sakura records symptoms only, and Horikita makes the final call. 55
• Identifies that Ryuuen is observing not merely Class D's prominent members, but the substitute chains that replace them, and records the resulting rotation schedule. 68
• Limits publicly shared Sports Festival information to confirmed registrations, current preparation statuses, and official notices rather than projections or comparisons with other classes. 121 136
• Keeps separate records for personal applications and internal reviews so that one applicant's actions cannot be confused with another's. 143
• Retains her own recovery time rather than allowing another applicant's review to turn her pause into an automatically available class resource. 146
• Distinguishes Gu's identification of a timing contradiction from an authorized record change, delaying submission until Sudou's official confirmation can be corrected. 182
• Evaluates plans against participants' explicit conditions, identifying when a recommendation improperly expands limited consent into unlimited availability. 186

Public Representation

Horikita becomes Class D's formal public representative because her visible role can absorb outside attention while preserving the class's internal strategic structure. 58 72

• Volunteers as the nighttime representative when the school makes that role public. 58
• Accepts the public representative field while Gu Heng registers as Class D's final-stage leader. 72
• Refuses Class C's attempts to equate her public role with the hidden final-stage leader. 73
• Establishes herself as Class D's authorized contact for future public matters in an exchange with Hashimoto. 74
• Acts as Class D's spokesperson when Class C attempts to turn Sports Festival preparation into public speculation and forced admissions. 132
• Is formally confirmed as Class D's public respondent, accepting responsibility for the public position without disclosing individual times or internal records. 133
• Guarantees only that Class D will follow its stated public wording, refusing to guarantee unannounced outcomes or speak for the school. 134 135
• Refuses Ryuuen's claim that she is merely Gu Heng's nominal representative by publicly declaring that she will accept only verifiable advice. 182
• Becomes the school-recognized independent representative for Class D's plan submissions; Gu Heng may review her work but cannot revise or submit it directly. 182
• Answers Ryuuen's challenge to Gu's rejected recommendations by defining his right to propose separately from her authority to accept or reject proposals. 186

Equipment / Items

• Rule notebook — Used to record warnings and classroom misconduct. 24 25
• Record board / clipboard — Used during the island exam to track duties, adjustments, substitutes, and violations. 37 38 69
• Terminal — Used to submit public-representative confirmations, monitor public status, and send official Class D responses. 59 72 74
• Sports Festival registration and record sheets — Used to separate event registrations, logistical assignments, public status, internal reviews, and official results. 117 135
• Representative confirmation records — Her published confirmation materials establish the scope of her independent submission authority. 182
• Risk file — Stores unverified material for later comparison without treating it as an official accusation or plan evidence. 182

Relationships

• Gu Heng — Strategic partner and frequent ideological opponent. He assigns her as Class D's visible leader while operating behind the scenes; she accepts the arrangement only after demanding that he address her directly rather than calculate her role without consultation. 21 22 Their partnership later develops into a clearer division between Horikita's public responsibility and Gu's management of internal strategic boundaries. 133 135 When Gu refuses sole submission authority, Horikita does not preserve the position for him; she becomes the class's official submitter and establishes that his review and recommendations do not automatically bind Class D. 181 182 186
• Yosuke Hirata — Co-leader and intermediary. Horikita works with Hirata to coordinate Class D's assignments, support him when he becomes overburdened, and manage crises such as the missing duty roster. 21 50 53 During the Sports Festival preparations, they jointly maintain the distinction between public responsibility and internally recorded individual performance. 133 135 In the later submission structure, Hirata confirms that members have completed personal reviews while Horikita makes final decisions, a division that reflects his preference for coordination over unilateral authority. 181 182
• Kiyotaka Ayanokoji — A reserved observer whose insights Horikita considers during the island exam. He shares Class C's leader-targeting information with her and participates in Class D's false-leader operation. 62 69 He later works alongside Gu and Horikita to preserve information boundaries surrounding Karuizawa and Class D's internal records. 89 111 During the representative restructuring, he remains outside the formal process but recognizes the significance of requiring Gu to confirm his own role. 181 182
• Ken Sudou — A difficult classmate whom Horikita disciplines directly. Her warnings and records help restrain his aggression, while Sudou gradually learns to follow her operational instructions. 24 46 59 He continues to support her public authority during Sports Festival preparations, including respecting her decision not to have others fill her spokesperson role. 120 134 As official submitter, Horikita defends Sudou's explicit workload limits against Gu's optimization-based proposal and records his event-related decisions only after personal confirmation. 182 186 187
• Kikyo Kushida — A useful but distrusted information collector. Horikita enforces boundaries on Kushida's methods and later refuses to reveal operational details prematurely at Kushida's request. 30 62 63 During Sports Festival preparations, Horikita prevents Kushida from using registrations and public-status discussions to extract private information or pressure individual students. 117 128 Horikita also rejects Kushida's attempt to equate emotional reassurance or popularity with representative authority, forcing the vacant role to be treated as a responsibility someone must explicitly accept. 181
• Hashimoto Masayoshi — A Class A representative who challenges Horikita's authority after Gu Heng is correctly guessed as Class D's leader; he ultimately records her as Class D's contact for future public negotiations. 74
• Kakeru Ryuuen — Class C's leader and a persistent opponent who tests Horikita's authority through public pressure, speculation, and demands for guarantees. Horikita repeatedly refuses to let him define Class D's public position or force disclosure of its internal records. 132 133 135 136 After she becomes Class D's official submitter, Ryuuen directly challenges whether she is independent of Gu; she answers by exercising the authority to reject his recommendations and personally submit Class D's decisions. 182 186 187
• Kei Karuizawa — A classmate whose privacy becomes a point of conflict during the Identity Exam. Horikita questions Gu about a deleted observation and later supports record boundaries that prevent private information from being treated as freely shareable class evidence. 89 115

Story Role / Major Arcs

Formation of Class D's Leadership Structure

Horikita initially investigates Gu Heng's prediction that Class D will lose all of its points, then becomes his reluctant partner in observing and stabilizing the class. 1 2

Before the Uninhabited Island Special Exam, Gu proposes a three-part structure: Horikita as Class D's face, Gu as its strategist, and Hirata as its bridge to the rest of the class. Horikita accepts the role but confronts Gu over his public criticism and his tendency to treat people as replaceable functions. 21 22

Discipline and Academic Recovery

Horikita enforces Class D's first internal rules through a notebook system, recording Sudou's misconduct and warnings against students who continue to disrupt the class. 24 25

During the academic assessment, she acknowledges that Class D's improvements come from a repeatable method rather than Gu Heng's authority alone. 17 19

Uninhabited Island Special Exam

Horikita leads Class D's visible operations, including task divisions, rescue decisions, relocation routes, patrol rules, and roster control. 38 44 46 51

When Class C pressures Class D through leaked information, false routes, and targeted substitutions, she becomes the visible “flag” of the class while helping Gu, Hirata, and Ayanokoji maintain the broader deception plan. 52 61 62

She volunteers as the publicly displayed nighttime representative, accepting the personal risk of having her movements and responsibilities exposed to the other classes. 58 59

Final Phase and Public Representation

Horikita formally registers as Class D's public representative, while Gu Heng privately becomes the final-stage leader. She maintains the distinction under pressure from Class C and Class A rather than allowing outside classes to define her as Gu's puppet. 72 73 74

With twenty-seven minutes remaining, she changes Class D's final confirmation target to the eastern public confirmation point. The class follows her order and ultimately finishes the special exam in second place. 79 80

Identity Exam Records and Privacy

After the Identity Exam settlement imposes a fifty-point deduction on Class D without identifying a submitter or answer, Horikita locks the class reply record and separates public-note permissions from personal results. 115

Her approach reflects an expanded form of rule enforcement: Class D must account for its collective outcome, but individual pages, private information, and unverified observations cannot automatically become material for public judgment. 89 115

Sports Festival Preparation and Public Position

Horikita organizes Class D's Sports Festival registration through simultaneous choices for physical events, logistical support, and substitutes, preventing the order of registration from coercing students into undesirable roles. 117

As Class C attempts to convert Class D's preparation into a public contest of speculation, Horikita serves as the class's spokesperson. She confirms Class D's public position while refusing to disclose individual times, internal records, or unannounced results. 132 133

When Ryuuen demands that she define Class D's guarantees, responsibility, and accountability, Horikita separates those issues across public-status, internal-review, and official-results sheets. She accepts responsibility for the public wording while preserving the boundaries of the other two categories. 135

Personal Applications and Recovery

As personal application procedures emerge, Horikita initiates her own application and internal review as a distinct action rather than an extension of a previous applicant's record. 143

She retains her recovery time even when doing so postpones the next segment and costs Class D an opportunity for simultaneous coordination. This decision reinforces her position that recovery, like participation, belongs to the person who bears its cost. 146

Official Representative and Submission Reform

When Gu Heng is absent from the first proposal meeting and later refuses sole submission authority, Horikita prevents the class from treating representation as a role that automatically returns to him. She converts the vacancy into a formal selection process based on personal acceptance of authority, deadlines, and refusal conditions. 181

Horikita then volunteers to become Class D's official representative. Under the new structure, she submits plans and makes final decisions, Gu reviews sources and procedural compliance without direct submission power, and Hirata verifies completion of personal reviews. 182

Her first submitted plan is accepted after she removes an insufficiently confirmed Temporary Exchange Authority arrangement and delays the submission to correct an inconsistency in Sudou's confirmation record. She also preserves an anonymous warning in a risk file without allowing it to become an accusation. 182

Consent-Based Event Selection

When Gu recommends an arrangement that would maximize Class D's expected results by placing Sudou in consecutive high-intensity events, Horikita refuses because it exceeds the conditions Sudou personally confirmed. 186

She distributes the Strength Event among four members instead, knowingly accepting weaker projected results. Horikita further clarifies that Gu's recommendations are proposals rather than orders, records rejected plans as unadopted, and mandates that future recommendations identify their worst possible consequence. 186

After Class C targets Sudou, Horikita submits a narrower relay-handoff modification that reduces risk without replacing participants or expanding Sudou's burden, demonstrating her ability to act independently within the new system. 187
