Yaya is a shy girl who doesn't have any real friend. Her mother passed away back when she was still very young and she is now living together with her father who is very strict 'cause he is afraid that something could happen to Yaya. Yaya loves music a lot, she always wanted to become an idol but because people around her never supported her, she lost her self confidence.
Back to Yaya and her classmates. At the beginning she is often hanging around with Moe and Seri who make her feel worse than she already felt. But there is also a person who seems to really like her:
Moriyama-kun. Yaya enjoys listening to his music and she soon realizes that she loves him, but she would never dare to tell him about her feelings.
Yaya's biggest hobby is the former Visual Key band "Juliet" and their front singer Shohei. Together with other Shohei/Juliet fans she's cosplaying in Harayuku on Sundays, the only day in the week when she can be her real self. On the right you can see Yaya as Cosplay girl.
