梶矢 彩乃

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.

Ayano has almost no weaknesses, except for one. Never being treated like a girl by others, she is very sensitive to everything that can be complimented by positively touching her femininity, making her very nervous, embarrassed and happy (especially when it is Ichio who does it). She is particularly embarrassed when Ichio delights himself in the smell she has deposited in the blankets in which she sleeps, calling him a pervert. 

She knows the entire erotic collection of Ichio, including his AVs, mangas and computer content as well as his preferences for "onee-san" type girls.

She is apparently a masturbation practitioner, "with the same frequency of use as Ichio"./
