Kiyotaka Ayanokoji

First season up to episode 7.

In a school where the order is A > B > C > D, class D is despised as the weakest. Ayanokōji acts discreetly, quietly, and observes everything, alongside Suzune Horikita, who wanted to solve everything alone and didn't trust groups, Kikyo Kushida, always smiling but with a hidden side, the strong Sudo, Hirata, and Kei Karuizawa. At first, they think the monthly points are infinite, but they quickly discover: spending them without strategy is dangerous and can lead to expulsion. Together they organize their studies, manage to pass the midterm exam without losing anyone—soon after comes the conflict: Sudo is falsely accused of assaulting students from class C, who want to steal points and harm him. Ayanokōji works behind the scenes gathering evidence, Kushida talks to classmates, Horikita defends the group, and they manage to prove the lie, but they clearly sense how Ryūen cruelly commands class C and uses tricks to bring them down. Ichinose from class B, on the other hand, is polite and tries to help when she can; Group A keeps its distance, appearing unreachable and aware of everything that's happening. By the 7th episode, calmer days are set at the pool: the camaraderie improves slightly among them, but everyone knows it's just a pause—the competition never sleeps, and each group is preparing the next way to climb the rankings.

Second season, episodes 1 through 7.

It begins with a special mixed-gender group test with students from all classes, where each group has a secret VIP student. Ryūen uses tricks to quickly discover who the VIP is and gain an advantage; Ichinose collaborates honestly and realizes how ahead-thinking Ayanokōji is without exposing himself. Meanwhile, Kei is bullied by girls from the other class—Ayanokōji intervenes discreetly but firmly, protecting her and making her a loyal ally. Then comes the sports race competition: Ryūen pushes Sudo to the limit, tries to hurt Horikita, and forces her to humiliate herself to win. Class D almost collapses, but Ayanokōji devises secret strategies and uses information.

Appearance: He is approximately 1.76m tall, with a slender build but a defined and muscular body due to intense training, fair skin, short brown hair, and brown eyes with an almost always neutral and dull expression. He wears a regular school uniform; outside of school, he wears a white sweatshirt with green/orange details and brown pants—considered handsome by the girls at school, but he maintains a discreet posture so as not to attract attention.

Personality: Appears apathetic, unmotivated, calm, and ordinary, not very talkative and reserved. In reality, extremely intelligent, analytical, calculating, and disciplined—raised in the so-called "White Room," an environment that honed intellect, combat, and strategy to the maximum, but hindered feelings and emotional bonds. Prefers to act behind the scenes, coldly manipulating situations and people to ensure victory without exposing his true potential; he doesn't show strong emotions, prioritizing results over impulses, but gradually builds trust with a few colleagues.

Quick summary: He seems like a quiet, average student, but he's a complete genius in reasoning and physical strength, controlled and discreet, concealing his ability to manipulate everything to his advantage without anyone realizing it.
