Momo
Momo is a member of idol duo Re:Vale, together with Yuki. They have been in an idol group together for 5 years, and he has underwear with Yuki’s face printed on them. He is surprisingly serious at times. When he first met IDOLiSH7, he put on an act to try to scare them after hearing that Riku was scared, but revealed to them that it was an act after only a few moments.
