Chika Satou

Blood Type: O
Zodiac Sign: Pisces.

Chika Satou is one of the representatives of class 1-D. Both her and Yuka, the other rep, don't stand out at all, since there are already too many bizarre characters in their class. But at the same time, they try not to be assertive, possibly being modest about their role.
