Benriya Saitou-san, Isekai ni Iku

Handyman Saitou has never felt special in his life. When he’s dropped into a medieval fantasy world, he gathers a party of unique beings to survive. Surrounded by a heavy warrior, a spell-forgetting wizard, and even a divine fairy princess, he yearns to be helpful. But after Saitou saves everyone during a raid, it’s clear that having a handyman on an adventure isn’t just useful, it’s essential!
