A very fluffy crossdresser who is able to create a soothing atmosphere without even trying. Although he joined POP'N STAR under Kokoro's invitation, he's still not used to wearing women's clothes. He switches back to boyish speech and sits with his legs open, which ends up with Kokoro scolding him for it. The plush toy he holds around, Ricky, was given to him by Kokoro to create his idol image. His hobby is gardening, and the school has a flower bed exclusively for him. He prefers that people call him "Momo" instead of "Momosuke" and becomes angry when people don't.
