"Koumi-jima Shuu 7 de Umeru Mesu-tachi" (also known as "Island of Childbearing Where Women Give Birth After 7 Weeks ") is an adult-oriented anime series that premiered in 2023. The protagonist, Seiichi Ozaki, is a teacher with a passion for exploring remote islands. He is invited to Ushiha Island, colloquially known as the "Island of Childbearing," to assume the role of the chief inseminator. Historically, women on this island have had the unique ability to conceive and give birth within a week. However, due to genetic issues among the male population, this phenomenon has been declining. Seiichi's task is to revitalize the island's population by impregnating its female inhabitants.
