Arifureta Shokugyou de Sekai Saikyou Novel

Seventeen-year-old Hajime Nagumo is an average otaku whose ordinary life is disrupted when he and his entire class are transported to a fantasy world. Presented as heroes destined to save humanity from extinction, the class receives powerful abilities to combat the world's monsters and demons. However, Hajime's job assignment as a Synergist grants him only a single transmutation skill, essentially making him a blacksmith. Lacking the godlike powers of his classmates, Hajime becomes the target of ridicule and bullying, quickly descending into despair. Forced to navigate a dangerous realm of monsters and demons with minimal strength compared to his peers, Hajime must find a way to survive and overcome his circumstances. His journey tests whether he can endure in this hostile fantasy world despite being vastly underestimated and underequipped compared to the rest of his class.
