ミモサ

Small body, big attitude!
A devil who's all bark and no bite!

Chihuahua owned by the gyaru sister. A dog who sneers at the protagonist. The gyaru sister raised her like a friend, so she never taught her to respect authority.
Because of that, she looks down on the protagonist and treats him with contempt.
However, she's all talk and has no particular knowledge or skills. Filled with weak points, she digs her own grave on a daily basis.

"Wha? Of course I know! I've done it before! I-I've got plenty of experience, lmao!"
