Ooura Miyuri

Transfer student. First year student at Meirin Academy.
Miori's younger sister.

Shy and quiet.
Shy, not good at talking to people, and has few friends.
Good at studying, always gets high grades.
On the other hand, she is physically weak, so she often watches PE classes.

Like Miori, she is also childhood friends with Suzune. She was physically weak when she was little, but thanks to training at the Ayajo Dojo with Suzune and Miori, she was able to get to school normally.
Miori has always protected her since she was little, so she wants to somehow repay her kindness.
