Momo is a member of Onigarashuu. She has got a black hair and always wears a bandit scarf. The others think that she is mute because she didn't speak from the very begining. In the first part of the manga she works as a caterer or something like that and wears a big Piyouta costume. By the way, she loves Piyouta. She is the only one who knows everthing about Saya and Tadashi's relationship.
