High-schooler Hajime Nagumo is bullied by the rest of his class for his relationship with the class idol, Kaori. When he and the rest of his class are transported to a fantasy world, all of his classmates get powerful magical abilities, while Hajime only gains the ability to transmute solid materials, a common ability usually found in craftsmen and smiths. During a dungeon raid, he is betrayed and left for dead, but survives. He must work to create weapons and tools to escape the dungeon and become stronger. On his journey, he meets and forms a relationship with the imprisoned vampire Yue, and later is joined by the bunny-eared Shea, the Dragonoid Tio, and others.
