18+ Haramasete Seiryuu-kun! Jingi Naki Onna no Tatakai

It seems that everyone is fighting over the main character Seiryu-kun's genes!! They've even made a competition out of it! However, little do they know of the suspicious plot behind the whole situation. In any case this is a crazy school love comedy adventure! An adventure of an upperclassman and her friend trying to be impregnated!
