In an alternate Tokyo of 2026, ghosts are not mere spirits of the dead there powers harnessed by both good and evil forces. The line between life and death is blurred, as spirits can possess the living, leading to fatal consequences. To combat this growing threat, special police academies train students to manage these spirits and protect their towns from dangerous possessions leading the best of the best from the special police academies to G.C.A. (Ghost. Containment. Agency.) Kokoshi, a shy and overthinking 19-year-old, is a student at one of these academies. His unique bond with his ghost, Yume, sets him apart. Yume, a ghost from 1834, has a strict yet playful demeanor, serving as both Kokoshi’s guide and weapon. With Kokoshi’s careful strategy and Yume’s spectral abilities, they defeat rogue spirits by feeding Yume the flesh of their defeated foes. But Kokoshi’s mission goes beyond just protecting his town. His determination to save others is deeply tied to his desire to escape his own past troubles and fears, especially his fear of witnessing death. As the stakes rise, Kokoshi must confront not only malevolent spirits but also the burdens of his own mind. Amid the horror and action, the manga infuses moments of humor, with Yume’s big personality clashing with Kokoshi’s introversion. Together, they navigate a world where the dead don’t rest, and where possessing a ghost can be both a gift and a curse.
