東雲 吉野

Classmate of Tarou. 3rd year high school student.
Probably because of her inhospitable atmosphere, she is always alone and is seen as mysterious.
She never attempts to become friends with anyone, but is open with Kotori. Due to her tall height, and her honest nature, she is intimidating to some people.
Doesn’t like that she can’t win against Tarou at studying.
Ouji wants her to join Seishun-bu, in order to meet certain conditions.
