|The kids call me "Ms. Yumi" but you can call me "Aiko"|
Aiko Yumi is a character from the 2015 dating sim "'HuniePop". Jack would consider her as his 3rd favorite from the game. 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.
