Melty Do Granite is a "tsundere" witch with a passion for ice magic. Preferring solitude, she lives in a mansion apart from the village, avoiding both people and sunlight, which she dislikes. Her path crosses with Rick's during his quest to gather ingredients for crafting "extreme ice cream."

In battle, Melty wields her icy magic creatively—her special attacks are ice cream-themed, blending her unique personality with her powers. She also has the ability to transfer damage to her loyal familiar spirit, Sorbet, making him a vital part of her combat strategy.
