Plot Yukito Kirihara is a high-school student who loves tabletop role-playing games. He gets reincarnated into Everworld, a fantasy world with swords and magic alongside his sister, who goes missing after being reincarnated. Yukito has a curse that makes his HP limit one, meaning that any damage can instantly kill him. Using a book he stole from the evil goddess Nephilia, he exploits loopholes in the rules of the world and other tricks to defeat his enemies. Yukito's fighting style resembles the munchkin style of pursuing optimal solutions.
