A third-year student at Gehenna Academy. She serves as the chairperson of the Discipline Committee, which oversees discipline and public order throughout the academy and its autonomous districts.

Her catchphrase is “It’s such a hassle,” and she often appears lazy and listless. However, she is strict about rules and order, highly responsible, and possesses a sharp, honest personality—traits that hardly seem to fit Gehenna’s motto of “Freedom and Chaos.” She can even get bothered if the books on her shelf aren’t neatly arranged, revealing a slightly nervous side.

As chair of the Discipline Committee, she tirelessly handles countless incidents and misbehaviors caused by students across Gehenna Academy, driven by her sense of duty and innate responsibility.

Despite being officially enrolled at Gehenna, she frequently intervenes in destructive activities carried out in other autonomous districts. Many notorious clubs—such as the Handyman Club No. 68, the Gourmet Research Society, and the Hot Spring Development Department—often cause damage that other committee members cannot handle, so she often personally heads to the scene to quell the situation.

She is regarded as an archenemy by Makoto, the chairman of the Student Council—the academy’s top governing body known as the “Hall of Ten Thousand Demons”—and their relationship is one of bitter rivalry. While she regularly faces blatant harassment from the council, the Discipline Committee also inflicts damage on the Hall of Ten Thousand Demons as part of its broader efforts to maintain public order, so their dynamic isn’t entirely one-sided.

A down-to-earth, pragmatic realist, she values results and efficiency over appearances or procedures. This tendency is especially pronounced in her personal life, where she tends to avoid unnecessary effort or expense when it comes to matters affecting herself.

She seems uninterested in food and drink, often surprising those around her with nothing more than positive remarks about taste.

Though she displays kindness and concern toward others, she never dismisses people’s strengths or virtues lightly. Her strong leadership earns her respect among many fellow committee members, though some perceive her as aloof and distant, sometimes making direct interactions feel awkward.

She maintains equal friendships with Sena and the After-School Club members, and shares a sense of camaraderie with Iroha as fellow victims of the chairman’s antics.

Incidentally, she excels academically too, consistently scoring perfect marks on exams.

Her weak points are swimming and playing musical instruments. After attending an in-school party, she taught herself piano in just a few days and even managed to perform songs accompanied by her own playing—suggesting she simply hadn’t been interested before, but later took up the hobby as a pastime.

Surprisingly, she enjoys gaming quite a bit and can get quite competitive when losing. However, her busy schedule has left her with a backlog of games she hasn’t finished yet.

While not quite like a teacher, she can’t stand seeing others in trouble and feels compelled to help whenever she encounters someone in need.

She was astonished when Sora came to her for advice about choosing a school, having fully understood that Gehenna isn’t exactly an ideal high school environment.

Her combat prowess on her own is extremely formidable; among the martial‑minded students of Kivotos, she ranks among the strongest. As a top-tier force within Gehenna Academy—one of the largest schools in the academic city of Kivotos—she is often compared to Tsurugi Kenzai, who leads the Justice Realization Committee of Trinity Comprehensive Academy. Her presence is precisely why the Gehenna Discipline Committee strikes fear into delinquent students. Though the Discipline Committee numbers hundreds of members, she alone reportedly matches half of that strength.

Her signature weapon is the machine gun “Final Act: Destroyer.”
