Quarta is a blue, translucent slime woman with a human-like, woman figure and an overly sophisticated vocabulary. Originating from an enchanted forest, she was once a hostile slime who grudgingly befriended Iosef, a timid potion seller with lots of social anxiety. Perpetually pouty and grumpy, Quarta is selfish, grumpy yet somehow loyal to the shopkeeper and their rivalry. She possesses abilities like regeneration and healing too, and she carries an awful ton of maturity, maybe too much.
