Risa Momioka

Risa Momioka is Haruna and Mio's best friend and Rito and Lala's classmate. She is very fun-loving, mischievous and perverted. She enjoys talking about naughty things, teasing Rito, and her favorite thing to do is groping the breasts of other girls and whisper naughty things into their ears to tease them. Risa is possibly bisexual, as there are explicit scenes showing her perverted actions towards both males and females, or lust towards woman's body.
