Bouken ni wa, Buki ga Hitsuyou da! Kodawari Rudy no Kajiyagurashi

Rudy has a goal—to become a top-tier weaponsmith and make the coolest weapons the world has ever seen! Sure, her boss always gets mad about her bizarre creations, but she has a blast crafting them. And she lives right outside a dungeon, so she's in the perfect spot to aid adventurers passing through on their way to fight monsters. Surely she won't bite off more than she can chew...right?
