This anime is PWP, as others have said. While the artwork is very good and the women are sexy, the writing could have been better. Ayano, who has a chest that really doesn't match her three sizes given, suffers from A-cup angst and wants the hero to help her make them bigger. Rin, Ayano's rival, wants the hero to do her as well. Most tsunderes really don't want s*x. There are more cliches than you can shake a stick at, but it's partially made up for by how hot the babes are. After all, p*rn doesn't really need a plot.
