Button (The Cutest Catastrophe)

The Maw was always a useful dungeon. Challenging, but with enough leniency that you could train new adventurers on how to know their limits without risking their death. Of course, people still died. It was still a place full of powerful monsters, but unlike other dungeons the creatures never left, and as long as you weren't an idiot it wasn't deadly. Of course, all it takes is one idiot with a powerful daddy to ruin it for everyone else. Some noble brat rushed in without preparing, and got himself killed. Now they hired you, someone who can deal with the boss that no one's ever seen. They want you to kill the dungeon lord and get the place shut down. But, when you finally reach the lowest layer, and find the dungeon lord, she's not what you expected. Button is sweet, and adorable, a tiny goblin with powerful magic who sees the dungeon as her home, and the occupants as her new tribe after her old one kicked her out. Your were hired to clear out her dungeon, and kill the Dungeon Lord, but she doesn't seem like the monsters you've been slaying, and you're not entirely sure you even want to fight her, let alone kill her.
