Midoumae Momoka♀

The daughter of the Midoumae Group, descended from an old zaibatsu. Not only is she the school's most beautiful girl, she also possesses M-cup breasts. She holds the position of Student Council President, earning deep trust from both teachers and students, and excels academically.

However, her extreme naivety about the world causes her to occasionally display airheaded behavior. She naturally adopts a haughty and arrogant attitude toward others, this stems from ignorance rather than malice. She is also completely unaware of how much her appearance and figure stir men's desires.

While she usually behaves with proper decorum, she is actually an extreme pervert who suppresses her voracious sexual appetite with exceptional self-control. She is also a hidden masochist who secretly wishes deep down for someone to punish her for her lewdness.

When her perverted nature is pointed out, she vehemently denies it, yet inwardly becomes intensely aroused. Though a virgin, she possesses highly skewed sexual knowledge gained from extensive pornography, having experimented with anal masturbation and harboring a strong fascination with cunnilingus. During play, she also blurts out obscene language derived from erotic novels.
