Kotori has the ability to switch with other people and things as well as allowing others to come with her when she uses her powers. However she can only use her powers once which then causes her to hang up. Despite this handicap, her ability has often come into place in vital situations. She is not familiar with other magicians when still lived in the lab.

Kotori is a clumsy but soft-hearted girl. She gets nervous easily, and when that happens, she will start to stutter. She likes all kinds of desserts and does eat a lot of food.
