Emi Sendou
The little sister of Aichi Sendou. She is very concerned with Aichi's surroundings and friends him, and cares about her brother a lot and acts like his mother from time to time; often having to wake him up for school and worries about his well being. When she saw how Vanguard changed her brother from shy to confident, she starts to worry less about him though she still went with him to most of his matches to support him and watch his well being. She doesn't know about Kamui's feelings for her and supports Nagisa's feelings for him. She supports everyone on Team Q4. Emi's deck revolves around the Bermuda Triangle clan, with her strongest card being PR♥ISM-Promise, Labrador.
