Cleto was born into a world where women hold absolute power and the concept of chastity is entirely reversed. Abandoned by his parents simply for being male, he lived as an orphan until a unique skill awakened within him one day: an Overwhelming Stamina Skill that grows stronger the more he engages in “activity” with women.

Through daily “training” with his dorm mother, Cleto gained strength that even surpassed women. Consequently, he is granted entry into an elite Knight Academy that was previously exclusively for females. To become a highly respected knight and reclaim the life he was denied, Cleto must now face the throngs of female students at the academy. He will have to clash with them not only in the arena but also in the bedroom, steadily gaining power and rising to become the hero of the all-female Knight Academy.
