Mina Ashido is an upbeat girl with pink skin and horns in Class 1-A whose Quirk is Acid, which allows her to excrete an acidic fluid from her body. Mina is a cheerful and easygoing girl who displays a smile on her face most of the time. Highly social and excitable, she loves to hang out with her friends and is shown to become very upset when denied an opportunity to be at a gathering. She possesses a strong fashion sense and likes to go shopping. Mina enjoys and is very skilled at dancing. Her demeanor becomes more strict and perfectionist when teaching others how to dance, in direct contrast to her usual happy-go-lucky nature. Mina is somewhat of a romantic and holds a lot of interest in the love lives of other people, to the point of being obnoxiously curious and intrusive about them. Her suspicions, however, tend to be rather baseless most of the time, as she seems to view any instance of a pairing as possible proof of a relationship regardless of compatibility.
