The protagonist of the hentaiji Amano by an unbelievable coincidence drinks the precious blood of Aoe Kuon, who is the most popular sex girl of the academy. Because of the blood of the heiress, our hero (or rather his sperm) has become very seductive to semi-humans. The mere sight of Taichi made a hundred beauties wet. The House of Aoe took it upon itself to protect our hero from the attacks of the half-humans. In exchange, Taichi was to cooperate with Aoe and help her awaken. In order to do so, however, he must cum profusely right into her pussy... The hunt for the hero's sperm gathers pace!
