Aida Miku

The heroine of the story. She is a first-year female student who attends a private academy.
She is somewhat short but has a curvy body that men find attractive. In particular, her G cup breasts attract lots of indecent stares from men around her, and she herself has a complex about it. Although she doesn't stand out in her class due to her being a late bloomer and shy around strangers, she is popular with male students due to her good-looking face and lewd body, even though she doesn't realize it herself. She loves her father (the protagonist) and wants to support him in place of her deceased mother. She has no romantic experience and gets nervous in front of men other than her father. As one would guess, she is a virgin.
