In response to the worsening crime rate, Japan creates Tokyo Butei High, an elite academy where "Butei" or armed detectives hone their deadly skills in hopes of becoming mercenary-like agents of justice. One particular Butei is Kinji Tooyama, an anti-social and curt sophomore dropout who was once a student of the combat-centric Assault Division. Kinji now lives a life of leisure studying logistics in order to cover up his powerful but embarrassing special ability. However, his peaceful days soon...
Hidan no Aria adapts the first 3 novels of Chuugaku Akamatsu's light novel series of the same title.
A snarky dropout and a gun‑toting prodigy team up to hunt a campus‑wide serial killer.
When Japan’s crime wave spirals out of control, the government launches Tokyo Butei High—a ruthless academy that trains teenage assassins to serve as elite law‑enforcers. Among its cadets is Kinji Tooyama, a sardonic sophomore who quit the cut‑throat Assault Division and now pretends to be a lazy logistics student. Beneath his apathetic façade lies a volatile power: a hidden gun‑firing ability that he keeps secret for fear of becoming a weapon himself. Kinji’s stagnant routine shatters when a notorious serial killer known as the "Butei Killer" begins targeting the school’s top students. Enter Aria Holmes Kanzaki, a prodigious, silver‑tongued gun‑girl who instantly rescues Kinji from a lethal ambush. Impressed by his raw talent, she forces him into a partnership, thrusting the reluctant duo into a whirlwind of high‑octane battles, snarky banter, and tangled feelings. As they hunt the murderous mastermind, Kinji must confront his own dangerous gift, while Aria’s relentless optimism challenges his cynical worldview. Together they navigate a world where schoolyard politics meet lethal firearms, and where every trigger pull could decide who lives or dies.
