About Demon City
Demon City (Oni Goroshi) is a 2025 Japanese live-action action-thriller, written and directed by Seiji Tanaka and adapted from Masamichi Kawabe's manga. Toma Ikuta stars as Shuhei Sakata, a quiet, supremely capable hitman whose ordinary life is shattered when a group of masked assailants storms his home and leaves him for dead. Framed for the very crimes committed against him, he survives against the odds and disappears into the margins of the provincial city of Shinjo.
Years later, Sakata resurfaces with a single purpose: to dismantle the corrupt cabal that destroyed his family and pinned the blame on him. The conspirators hide behind respectable public faces, the masked Kimen-gumi operating beneath the polished surface of civic life, and Sakata methodically works his way toward the men who orchestrated his downfall. The film treats his campaign as a stylized revenge tragedy rather than a simple action spectacle.
Backed by a brooding score from guitarist Tomoyasu Hotei, Demon City unfolds as a moody, propulsive thriller about a framed man tearing a hidden conspiracy apart from the inside. The story keeps its violence in service of its central question, asking what is left of a person once everything has been taken and only retribution remains.
