Kotori can swap places with other people and objects, and she's able to bring others along when she does it—though there's a major catch. She can only use this power once before it basically shuts down, leaving her completely drained. It's a serious limitation, but her ability has pulled through in some surprisingly crucial moments anyway.
Growing up in the lab, Kotori never got the chance to interact with other magicians, so she's pretty unfamiliar with that whole world. These days, she's known for being clumsy and having a genuinely kind heart, even if she's a nervous person by nature. When she gets anxious, she starts stuttering pretty noticeably. On a lighter note, she's obsessed with desserts—like, all kinds of them—and fans often note that she'll eat just about anything sweet put in front of her.
