|“||The kids call me "Ms. Yumi" but you can call me "Aiko"||”|
|Alias||Ms. Yumi, Asian Chick Ms. Professor|
Aiko is shown to have black hair with a part stuck up at the back, two strands hanging either side of her face and glasses. She dresses rather inappropriately, first shown wearing a green jacket over a white shirt, black tie, white shorts and high heels.
During one of the dates in episode 4, she is dressed in a purple top with red shorts and high heels.
Jack would find it really hard to reach out to Aiko through conversations and compliments. While viewing Aiko's first photo, Jack said she would be fired if she wore knee socks during teaching sessions.
