Protagonist

Reina kurashiki is exactly like the character Reina Kurashiki, not only the name but the appearance

Reina is one of the protagonists of Hentai "saimin seishidou", I personally recommend it a lot

secondary characters of greater importance;

friend Rebeca Santos, Brazilian exchange slut, black skin and sensual body

friend Sakura Miyajima, strong bitch and president of the school dojo

friend Tomo Aizawa, Tomboy girl, dresses and acts like a boy but is a big hot bitch

Brother Akira Kurashiki, inherited the family's good genes but wasted them on fatty foods and social phobia, is a hidden pervert with love for his sister

---------

(the list will be expanded in the future)
