Akane Tachibana, a third-year student in Class 3-A at Advanced Nurturing High School, serves as the Student Council secretary with steadfast loyalty to former president Manabu Horikita. Her role extends beyond administrative support, often positioning her as a protective figure who upholds his decisions even when privately conflicted. This dynamic strains when Manabu unexpectedly invites Kiyotaka Ayanokōji to join the council, sparking her quiet dissent—though a single glare from him swiftly quells her objections. Her devotion faces its greatest trial during a school-wide training camp, where rival council member Miyabi Nagumo isolates her within a group and engineers her potential expulsion. Despite the threat, Akane shoulders the crisis alone, refusing to compromise Manabu’s position. His intervention, sacrificing substantial class and private points to rescue her, underscores their mutual reliance. Initially skeptical of Kiyotaka’s casual demeanor toward Manabu, Akane clashes with him over perceived disrespect. Yet she gradually reveals vulnerability, confiding her concerns for Manabu’s well-being—a stark contrast to her usual guardedness. Sporting lilac hair, orange eyes, and a petite 155 cm frame, Akane balances sharp organizational skills with a quietly independent streak. Her meticulous planning ensures operational harmony, though this rigor sometimes edges into inflexibility. Post-graduation, she continues aiding Manabu discreetly, their relationship carrying unspoken sentiments he dismisses as non-romantic. Before departing, he shares her contact with Kiyotaka, hinting at her lingering influence. Defined by unyielding self-sufficiency, Akane confronts challenges alone, masking stress with resolve—even shedding tears in secret before regrouping. Her arc weaves loyalty and emotional resilience, concluding with her graduation as an enigma, her path forward deliberately uncharted.
