Handyman Saitou in Another World

便利屋斎藤さん、異世界に行く

Saitou, an underappreciated handyman from modern Japan, wakes up in a fantasy world and joins a dungeon-crawling party: Raelza the swordswoman, Morlock the elderly wizard who forgets his spells mid-cast, and Lafanpan the stingy fairy. With no combat magic or swordsmanship, Saitou contributes by picking locks, repairing gear, and rigging solutions from hardware-store instincts. Short vignettes follow the party and surrounding townsfolk through the Great Labyrinth's floors, anchored less in overarching plot than in the small satisfactions of being genuinely useful.
