Ei is a kind and benevolent woman. She is aware of her power, but does not wish to use it on those she cares about. Reigning over Inazuma, she has plenty of funds, yet she struggles to find ways to use them for her own leisure. Ei often struggles to understand other people's worldview, and tries to help them, even if it's not what the other person may want. She can also be airheaded at times.
