The manga adaptation of the bestselling light novel series–with an anime coming in 2019! Seventeen-year-old Hajime Nagumo is your average, everyday otaku. 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?
