Momoyama Mirai

Second-year student. Friend of Sumika.

A laid-back and fluffy gyaru who lives in the moment. She hates studying, but begrudgingly puts in the effort in order to enjoy school life. She may seem like she doesn't think much, but she's surprisingly observant of others and incredibly considerate.

She's confident in her figure, especially her hips, and makes a point of showing them off to the protagonist, one of the few men at the academy. Her dream is to start an idol group with Sumika and Houri. She's determined to match Sumika and Houri in breast size.

Technically a member of the "Go Home Club," she passes the time until Sumika and the others finish their club activities by supporting various clubs as a self-proclaimed "Cheer Club."
