Ogata Hyakunosuke has died, and now he is trapped in his rifle, awakened by the touch of a stranger. He can telepathically talk with the wielder of the gun when they touch it, can see and hear the world outside, and can feel the touches through the surface of the rifle, but Ogata is unable to move or act on his own. People he knew are dead and he lost. Nor dead nor truly alive, he needs to figure out what he should do now and if heʼll be able to leave the gun and find peace.
