Based on looks alone, Maria is an ordinary, hard-working student who's not particularly concerned with the sexual realm. Her grades are top of the class, and so is her popularity with boys. In secret, however, she's been selling her body at school every day since she started. She's never once been discovered, possibly because she's good at deceiving men. She and Mio are both in the same class, but to keep up appearances they don't really interact. She's quite strict on pricing and seldom responds well to haggling attempts.

A dumb, excitable gal.

A typical gal who, based on looks alone, one probably would assume is mired in sex. However, she's also a friendly girl who's good at cooking and very family-oriented, so she doesn't make too big an impact in class.
She has decent grades and is pretty good at other things, so she's a sort of middleground type-person.
Maria turned her on to selling sex at school, and she's gotten really into it on account of her love of sex. Her payment is usually based on how much fun she had.
