Introduction: A Starting Point in a New World

Apart from the students of the White Room, Horikita Suzune was the first person from the outside world with whom Ayanokouji came into contact. The author has repeatedly referred to her as the protagonist’s “starting point” in ordinary society. She did not become his first friend—that place was taken by Yuki and Shiro—but, judging by the development of the plot, she turned out to be the first person with whom he began to feel a genuine bond, no matter how actively he denied it in his internal monologues (the most striking example being his reflections on “tools” in Y1V3). This dynamic lays the foundation for one of the most complex and significant relationships in the entire story.

Chapter 1. Mirror Parallelism: Loneliness Inside Out

Kinugasa deliberately constructed the initial portrayals of Horikita and Ayanokouji as mirror images. Both are loners with severe communication problems, but the causes of their isolation are opposite.

· Ayanokouji strives to make friends so as not to stand out as a social failure.

· Horikita consciously rejects any attempts at closeness in order to remain invulnerable and not show weakness—especially in front of her brother Manabu.

This mirroring is not accidental; it is a conscious authorial device that sets the tone for the entire first year. Throughout Y1, Ayanokouji, in parallel with his own affairs, systematically helps Horikita reconsider her views and grow. As a result, she abandons blindly imitating her brother and begins to forge her own path. Manabu himself, in turn, pushes Kiyotaka to leave his mark on the school so that he will be remembered before returning to the White Room, and passes on his contacts—a groundwork for a future alliance.

Chapter 2. Evolution by Year: From Dependent Ally to Main Adversary

First Year: Investments and First Shoots

Ayanokouji's role in Horikita’s development as a leader is hard to overestimate. He gently but consistently points out her mistakes, pushes her toward cooperation with the class, and gradually draws her out of her brother’s shadow. By the end of the year, she is no longer "Manabu’s little sister" but an independent player whose progress is recognized even by other leaders.

Second Year: Payoff and Unconscious Awakening

In the second year, the training bears fruit. Horikita is officially recognized as the class leader, takes the post of student council president after Nagumo's departure, and even turns Kushida into a genuine ally—with Ayanokouji’s support, but with her own decisive role. Ayanokouji sees the results of his investments and, by some indications, feels pride—a rare emotion for him.

A key moment is the café scene in Y2V10 and the side-story of the same name, “Unconscious Awakening.” Horikita, unexpectedly even to herself, smiled, and Ayanokouji “mirrored” her smile, creating a unique and refreshing moment. But when Suzune pointed out his rare smile, he responded with a serious expression, beginning to reflect: “Why did I smile?” This episode is the clearest illustration of how his true, nascent emotions come into conflict with the “protocol” of the White Room. He himself cannot rationally explain the nature of this warmth, comparing the sensation to “an absolutely white scrapbook into which colors have been added.”

In Y2V12, he sincerely comforts her and embraces her after her defeat by Ichinose. A detail on the illustration is noteworthy: in all the hugging scenes with Kei or Ichinose, Ayanokouji’s face is emotionless and turned toward the reader; only in the scene with Horikita is he depicted from behind, his emotions hidden. This is a visual device emphasizing that here, precisely, there is something the hero is not ready to reveal even to himself.

The end of the second year (Y2V12.5) becomes a turning point: Ayanokouji leaves the class and transfers to the opponents, leaving Horikita to fight alone—armed with everything he has taught her. He was confident that she would withstand the blow. The plan to transfer had been nurtured since the beginning of the second year, and its deep purpose is not merely opposition but an existential proof.

Third Year: Crisis and a Glimpse from the Future

Horikita’s reaction—depression and a temporary loss of class efficiency in Y3V1—is psychologically justified. Her closest ally left without explanation, and now her class faces the cruel truth: “if they cannot defeat Ayanokouji, they cannot graduate as Class A.” To demand immediate mobilization would be to ignore the human nature that the author himself consistently explores.

In Y3V2, no significant development of their dynamic occurs, but the volume ends with a monologue by Horikita from the future. She reveals that she learned about Ayanokouji’s past, speaks of it as though something bad has happened to him, and makes it clear that she has played and will continue to play an important role in his life after graduation. This is consistent with the author's earlier promise that the meeting between Horikita and Atsuomi—Kiyotaka’s father—is not the last.

Chapter 3. Self-Deception as an Authorial Method: The Voice of the “White Room”

Kinugasa rarely writes directly. Ayanokouji is a classic “unreliable narrator,” raised as an ideal tool. Therefore, any deviation from the “protocol” is immediately masked by his mind with rational explanations.

A telling example is the absurd situation where Horikita gets her hand stuck in a thermos and is too embarrassed to call for help. Upon finding her, Ayanokouji, in his monologue, long reflects that this is “a chance to analyze Horikita’s weaknesses” and “understand the limits of her composure for future exams,” while simultaneously complaining that he has to help a would-be leader. In reality, he is simply teasing her and delaying the rescue because he is having fun. This is pure childishness, which he unsuccessfully clothes in the garb of cold analysis. Such a pattern of behavior can be traced in many episodes: every irrational action immediately receives a “logical crutch”—and it is precisely this internal struggle of the machine with awakening humanity that constitutes one of the main psychological layers of the story.

Chapter 4. Strategic Intent: Proof Through Defeat

The entire arc of “cultivating” Horikita has a clear ideological underpinning. Ayanokouji wants to lose to her honestly in the finale in order to refute the dogma of the White Room: “an artificially grown genius is incapable of losing to an ordinary person from an ordinary environment.” Horikita thus becomes not merely an ally but living proof that environment and freedom can create a personality equal to or surpassing the “masterpiece.”

That is precisely why his transfer to another class is not betrayal in the usual sense, but a harsh yet necessary condition of the game. By concealing his motives, he seems to issue her a challenge: “If you want answers—defeat me.” Horikita has accepted this challenge.

Chapter 5. Parallel Lines and Their Function

Kei Karuizawa: “A Textbook of Love”

In the afterwords, Kinugasa asked readers to separate Ayanokouji’s romantic experience from his main life goal. He explicitly called his relationship with Kei a “textbook of love”—it was needed in order to understand the mechanics of paired relationships from a scientific point of view. Kei fulfilled this function, and in the third year, as we know, their paths diverged. The author himself emphasized that with Horikita a different, more fundamental process is underway—a mental and strategic partnership that shapes Kiyotaka as a person.

Hiyori: First Love or a Dangerous Experiment?

There is a well-founded theory that in the third year, Hiyori becomes the object of Ayanokouji’s first romantic attraction. He becomes aware of emotions that are new to him, but herein lies a trap: his interest in emotions is unhealthy, almost investigatory in nature, encompassing not only positive but also negative experiences. There is a risk that he will want to deliberately cause her pain—for example, by bringing about her expulsion—in order to study the full gamut of feelings.

1) Authorial hints point to this: at the beginning of the story, Horikita gives him the book “Farewell, My Love” to return, and in the library he meets Hiyori for the first time.

2) The Language of Flowers: In the classical language of flowers (hanakotoba), the poppy has several meanings, but in the context of a single flower, the dominant ones become “farewell,” “consolation in suffering,” and “fleeting, ephemeral love.” In Western symbolism, the red poppy is also often associated with remembrance of those who are no longer here and with sleep-oblivion.

3) In her inner thoughts, there flickers a clear presentiment that one day she will disappear from his life. If we regard Horikita as the final point of development, then the line with Hiyori may play the role of a “cathartic” episode: having passed through destructive experience, Kiyotaka will rid himself of the unhealthy thirst for emotions and approach the final bond as a more whole person.

Chapter 6. The Author’s Words and Meta-Narrative: A Look Beyond the School

Kinugasa has stated that by the end of the second year, approximately 50–70% of the whole story has passed. This means that the three-year school arc is not the finale, and after graduation a continuation connected with the confrontation against the White Room will follow. In this phase, Horikita’s role will likely extend beyond the school. The scene of the meeting with Atsuomi and the author’s promise that they will meet again allow for the most varied options—up to and including Horikita and Manabu eventually entering a political struggle against Ayanokouji’s father and the White Room in order to free him, since the work itself pits the two viewpoints of the White Room and the Advanced Nurturing High School against each other.

In interviews, Kinugasa avoids direct answers to the question of whether they will become a couple, but he provides weighty hints:

· In one interview, he stated that Horikita, among others, “has the possibility of being with Ayanokouji,” which is a direct authorial intention.

· Horikita is the only character whose tears Kiyotaka has seen twice, and both times he was alone with her (Y1V11.5 and the end of the second year).

· The sincere smiles and warmth he displays next to Suzune are, in the author’s words, what “the third year is being written for.”

Taking into account all the facts of Horikita and Ayanokouji’s relationship and where everything is heading, one can say with certainty: if the author plans to create a relationship, it will be after the third year in the battle with the White Room at the finale.

There is also an amusing circumstance: in parallel with the light novel, a mini-manga “√Horikita” was released, offering an alternative development of events in the genre of romantic comedy, where the romantic elements were much more noticeable. Kinugasa admitted that the story was originally conceived precisely as a romantic comedy, but in the process transformed into a psychological thriller. This gives some readers grounds to consider that mini-manga as a “beta version” of a possible finale—with due allowance for the depth and complexity of the main plot, of course.

Conclusion: An Answer Written in Action

From the very first pages, the author posed the central question: “Can a person change because of their environment?” Horikita and Ayanokouji are two sides of a single experiment. Suzune changes under the influence of the environment and with Kiyotaka’s help; Kiyotaka, without fully realizing it himself, changes under the influence of his bond with her. Their final confrontation in the third year, according to the author’s design, will become the culmination of the entire structure of COTE—and the definitive answer to that question.

Until then, it remains to watch how the flawless machine learns to smile—and how the girl who was once afraid of being vulnerable becomes the strongest argument against an entire system.
