Benriya Saitou-san, Isekai ni Iku

Saitou spent his life as a handyman, repairing locks, tools, and countless small problems without ever feeling that anyone truly valued what he could do. After losing his job, he suddenly finds himself in a world of swords and magic and joins a party made up of the warrior Raelza, the fairy Lafanpan, and the forgetful mage Morlock.

Saitou has no overwhelming magic or heroic strength, but he can pick locks, repair equipment, and notice practical details everyone else overlooks. Inside dangerous dungeons, those ordinary skills repeatedly become the reason his companions survive. For the first time, Saitou experiences what it means to be genuinely needed, while his travels connect him with eccentric people whose separate stories gradually begin to fit into something much larger.
