Mine Kuramae works at Ayame Sohma's clothing store as a designer and seamstress, and lives with him in an apartment above the store. She is passionate, cheerful, and determined to do anything for Ayame; she takes care of details he neglects in his enthusiasm, such as getting permission to visit Yuki's class. According to Natsuki Takaya, "she is an amazing person" for being able to keep up with Ayame. She is depicted as especially enthusiastic about dressing girls up in her outfits, sparkling at the thought of doing so, and she herself is always shown wearing a frilly maid's uniform. According to Ayame, Mine is someone he "can confide in."
SpoilerWhen Ayame is freed from the curse, the first thing he does is embrace her.
