However, his simple life of pulling all-nighters and sleeping in school is suddenly turned upside down when he, along with the rest of his class, is summoned to a fantasy world! While the rest of his class are blessed with godlike powers and tasked with saving the human race from extinction, Hajime's job, a Synergist, only has a single transmutation skill. Will he be able to survive in this dangerous world of monsters and demons with only a glorified blacksmith's level of strength?
Long before any child of Earth came to the world of Tortus, the Liberators fought their own war: a struggle against the gods themselves.

But when the powerful magician Miledi Reisen barges into his life, he's swept up into the tides of history. When the two of them meet, sparks fly that will set the whole world ablaze!
