My [Repair] Skill Became a Versatile Cheat, So I Think I'll Open a Weapon Shop (Manga) Vol. 1

A plucky adventurer finds his true calling with crafting in this twist on a dungeon crawl fantasy! It's hard for Luke to make a name for himself as an adventurer, especially when he's perpetually low-ranked and only possesses the skill [Repair]. But when Luke, abandoned by his party, uses that same [Repair] skill to escape a dangerous dungeon, the skill levels up with him, and a new world of possibilities opens up. Maybe he doesn't want to risk his life adventuring at all. Maybe he can open a weapons shop where [Repair] empowers other warriors instead! Will this be the start of a peaceful new life, or a prequel to unexpected trouble?
