Ember 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 Venom.

Ember 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 to.

It is shown that before entering U.A., Ember would condemn bullying in middle school. She is capable of standing up for people even when she herself is scared, going as far as to put herself between her friends and a dangerous, intimidating figure in order to keep them safe, doing whatever she could to prevent the situation from escalating further.
