Saionji Mizuho

"I'm sorry. I'd really love to, but I have to study..."

The daughter of the school board chairman, and niece of Saionji-sensei. Mizuho is also the class representative for Yuuto's class.

She's a serious bookworm who's far too shy to look other people in the eye. She also has a rather weak constitution, which often causes her to have to go to the nurse's office due to anemia.
