Shinmachi Momo

A popular idol whose fan club the main character is a member of.

Her personality is cheerful and positive, and she is more like a girl you would like to have as a younger sister than an idol.
Originally, she was an idol from an unsuccessful agency that held small live shows, but her character and dance performances were picked up by TV and she began to gain popularity, and now she often appears on TV.
However, she has always valued her close contact with her fans, and her popularity is further enhanced by the fact that she holds live performances and handshake events, both large and small, to maintain a close relationship with her fans.
The main character, who became a fan even before she became popular this way and enthusiastically supported her with handmade goods, is treated a little more specially than other fans and called "Onii-san.
However, this has not become a problem due to his cheerful and unpretentious character, and in fact, it has become a tradition at handshake events, where other fans take a favorable view of him.
