Ayano is a third-year student and a friend of
Tomoko. She has been
Ichio's best friend since kindergarten and she treats him and considers him as her little brother, making their relationship a little ambiguous in the eyes of others, taking him by the neck and really being close to him (physically). However, neither she nor he sees the other as actually a member of the opposite sex.
Having an extraordinary personality, Ayano is appreciated by everyone in the school. However, no one sees or treats her as a girl because of her extraordinary personality. In fact, she is quite similar to Ichio but in worse because she has no embarrassment with the girls, which allows her to tease her friends a lot. When Ayano learns that Ichio is surrounded by pretty girls with whom he is preparing the Christmas party, she decides to join the group as a volunteer to help them, supposedly because "things might get fun".
For some time now, Ayano has been getting closer to
Seiji because they have Ichio as a common friend, which has given birth to rumours about them saying that they are dating, which is completely false and impossible.
She is a great food lover, especially of ramen, a passion she shares with Ichio. She'd eat tons of it if her money would allow her to.
