An anonymous person's anonymous OC is told that their Dean needs some storage to house important goods. They kindly (arrogantly) prove that they can easily do something like that

Additional notes - Inspired by Bis-maki and Zui's Treasure chest tf. It's so good.

Anyway side note, the slime actually tried to turn back to her normal form instead of remaining stuck as a treasure chest. It didn't go so well and ends up making things worse for her. That's always fun isn't it?
