 * Alpha Bitch: : Ījima Yuka from the second game is this in contrast to the first. Though it's largely a facade for her own deep-seated issues.
 * Chivalrous Pervert: At least this is what Professor Hitosuji believes himself to be.
 * Cool Teacher: Professor Hitosuji's cultivated this reputation for himself. Though he admits quietly that he's only in it for the money and sex.
 * The Ingenue: Shirakawa Reiko, the "heroine" of the first game, is this. She's portrayed as sheltered and incredibly naive.
 * Jerk with a Heart of Gold: While he has no qualms seducing the girls he's "tutoring," he still tries to understand them.
 * Lonely Rich Kid: The girls Professor Hitosuji seduces tutors in the series generally come from wealthy families.
 * Teacher-Student Romance: The premise of the whole series in a nutshell is taking this to its logical, sexual conclusion in various ways. All the while making sure no one else knows about it.
