My [Repair] Skill Became a Versatile Cheat, So I Think I'll Open a Weapon Shop (Manga) Vol. 5

It's hard for Luke to make a name for himself as an adventurer with all the competition - especially when he's a perpetually low-ranked adventurer whose only skill is [repair]. But when Luke is abandoned by his party and uses that same [repair] skill to survive and escape the dungeon, a new world of possibilities opens up. Suddenly, his despised skill allows him not only to survive but to stand out in a crowded field!
