Harem Shima e Youkoso

A group of students from an Exploration Club are swept away by a storm and transported to a mysterious island in another world. They are greeted by a village chief who reveals that the island is populated only by women and is in danger of dying out. The chief asks the boys to help “revitalize” the island by fathering children with the local women, a request that leads to explicit romantic and sexual encounters. As they navigate this new reality, the group must come to terms with their situation while searching for a way back home.
