Asuka Tooyama
This blue-haired wunderfrau may play tennis, but she is not self-made. She plays tennis and can swim all because of the player character. She is obsessed with him and almost totally subservient except for when she gets flustered. Then she might put her foot down. Also has a dysfunctional relationship with her mother.
The way she reacts to being harassed gives young men the wrong idea about consent, and despite not having been spied on in the school nurse's office, the player decides to impregnate her, an underage girl.
Kaoru Saionji
A character who would be dismissed as "frigid". The player character spies on her while she's changing for an inspection from the school nurse and decides to impregnate her and twenty other girls, and yet she confides in him.
Like Asuka, Kaoru has a dysfuntional relationship with her parents.
Ren Kagami
A beautifully-designed character with wavy golden bunches. Fits into the "dependent" fantasy. Written with an older brother complex. Father is barely around, and her mother's affair with the player character, also her childhood friend, risks tearing apart her family. And they say her game has no plot.
Ai Ogitsu
Scruffy blue-haired bike-riding tomboy. Does obscene things to the player character and is brainwashed into sex. Is a punishment fantasy towards girls who disrupt the established order.
Irina Putina
Is part of the "taming the Amazon" fetish, deludes the player into believing any strong girl is "playing hard to get".
Ai Rohan
Like Irina, Rohan is characterised as a conquest, a "tamed Amazon". The most I can say about her is that she's definitely smarter than the Girls Book Maker version of Arsène Lupin.
Miyako Andou
Another punishment fantasy, this time for a girl characterised as a know-it-all loudmouth percieved as stepping out of line.
Touko Shiranui
Like Kaoru, Touko is a character who would be dismissed by a real life man as "frigid". The real twist in her character is that for some reason she wants to be trapped in that cabin in the woods. Or was it a temple in the mountains? This sends the player mixed messages "No means yes" messages. Furthermore, like Ai Ogitsu, she is subjected to magical brainwashing.
Nanako Kugayama
Same as Touko, but Nanako has the strange side job of doing voice acting for dirty cartoons, adding to the "asking for it" delusion. So much emphasis in the dialogue is put on her alleged "playing hard to get" personality that she's as much of a stereotype as the rest of them. She is also a victim of surprise harassments as part of the gameplay.
