Saitou gets a new life as an adventurer in another world. He joins a party with armored warrior Raelza, the fairy Lafanpan, and the wizard Morlock. As he begins his adventures, he makes full use of the skills he cultivated in his last life as a handyman.

When the wire cutters that Saitou brought with him from his last life break, he asks a dwarf named Dohnbain to fix them. Later, when Saitou can’t stop wondering about the golem they defeated, he and the rest of the party head into the great labyrinth.
