Mina is cheerful and most of the time seen with a smile on her face. She is easily excited, but also very emotional and easily brought to tears in various situations, out of relief, out of sadness and out of frustration. However, she is still very easygoing, having no problem being completely naked in front of other people, however she still doesn't appreciate being peeped at by Minoru Mineta

Mina is also very sociable and eager to engage in social situations, and is shown to become very upset when she is denied an opportunity to be at a gathering or event she looks forward too.
