Yumiko

Yumiko is Takuya's and Asuka's classmate. She's a local know-it-all gossipy type of girl that has info on all students and new events at school and she's also good friends with Asuka. Takuya on the other hand seems to not like her that much and considering her personality, that might not be strange at all. After all, it seems that maybe she also kind of dislikes him as well, considering that she willingly participated and maybe even masterminded herself a plot for a prank in which female Takuya was framed for a fake love letter sent to their teacher Sano.
