Akatsuki Ayase

Introduced in the second year of the story, she is a second year student and the Archery Club's ace. She is a classmate of Akiho and Haruka. She has short dark blue hair, and wears short athletic tights under her school uniform. She is a childhood friend of Yū, and immediately rushes to Yū's side should something happen to her. One of her grievances is that she is completely flat-chested, and once attempted to increase her bust size along with Akiho following bad advice from Mafuyu. (Source: Wikipedia)
