Space-time collapses, order crumbles, and characters and objects from the 2D world descend upon reality. Shiro, transported to Tokyo, awakens a sign-in system in this increasingly dangerous world. Signing in at the Hokage Rock grants him "Shinra Tensei"! At the Sky Island, he gains "Rokushiki"! At the Karin Tower, he obtains "Kaio-ken"! Initially aiming for a quiet life, reality forces his hand. Oh well, let the world experience pain!
