Monmusu Island Overview
A curse wipes out monsters on Monmusu Island, leaving only Neko, Usagi, and Ushi. To save the island, they summon an outsider—an ordinary, perverted but inexperienced human MC—to help restore normalcy.
Story
On Monmusu Island, a pandemic-based curse has caused the extinction of monsters. Neko from the cat race, Usagi from the rabbit race, and Ushi from the cow race make up the final 3 species of female monsters.
The three race has taken the initiative to restore normalcy to Monster Island. They learn ancient magic that allows them to call on outside beings to assist them in finding solutions. They carry out the ceremony and are successful in calling out assistance.
MC is a regular person who only engages in daily masturbation and eroge gaming. Although he is incredibly perverted, he is essentially a virgin and has never made love.
