Yuu Kamishiro was a boy who didn't exist. Pushed to the brink by relentless bullying, he vanished from society, spending his days in a dark room and his nights wandering the streets. But in that darkness, Yuu found a lifeline: a boxing textbook and a desire to stop being a victim. He practiced a single straight punch thousands of times until it became a part of him. Now, when the predators of the night come for him, they don't find a victim they find a ghost who hits back with the force of a professional. This is the story of a boy carving out a Holyland in a world that never wanted him.
