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

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

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

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

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

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

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

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
• 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
• 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
• 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
• 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
• 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
• 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
