Mikado Azusa

A member of the track team and Yuto's childhood friend.
When they were young, they were quite close and frequently went to each other's houses.
However, as Yuto became more shy as he grew up, Azusa, on the other hand, became more active.
After entering school, she joined the track team, where she excelled in the short-distance race.
She has a cheerful and active personality and is sometimes harsh with Yuto, who does not try to exercise at all.
She secretly has a crush on Misa, a senior member of the same track team.
