One of Manami's good friends. She was the type to believe everything Manami says (just because they were friends and Manami looked so innocent) until she found out Manami was lying about everything and Ayumu was telling the turth. But, she still listens to everything Manami says because Hirose "Did" help to bully Ayumu. (plus, Manami said she'd kill her if she said anything; so blackmail)
