Maybe it's just that there's been nearly a decade of contradictory information — when this doujin was released, the Cinderella Girls game wasn't even a year old — but while I can see this version of Rin if I squint, this Uzuki seems wildly over-assertive. It's a little ironic that all the characterizations are more accurate in Cinderella Girls Love 2, even though the central conceit of that one is Rika convincing her big sister to have sex with her.
