, a young man with calloused hands and a restless spirit, the island wasn't just a home—it was a puzzle he was determined to solve.
For hundreds of years, a unique biological phenomenon has occurred: the island's women can carry and give birth to a child in just one week. This has led to a society where women significantly outnumber men. However, this unusual fertility has resulted in genetic degradation among the male population, leading to widespread infertility.

However, this once-functional system is beginning to fail. The problem lies not with the women but with the island's male population. Generations of isolation have led to a severe deterioration in the quality of the local gene pool. The women of Ushiha, all of whom are described as being of unparalleled beauty, have become unable to conceive. The solution, as presented to Ozaki, is simple: the island requires "fresh" genetic material from the outside world, and the teacher's lust is, appropriately enough, described as insatiable.

The franchise explores dark fantasy themes centered around a remote island with highly unconventional biology and isolationist customs. For hundreds of years, a unique biological phenomenon
Koumi-jima pushes the "survival of the fittest" concept to its logical extreme. The island's unique biological conditions create a Darwinian pressure-cooker that forces characters to confront what they are truly willing to do to live another day. The narrative forces both characters and viewers to face distressing moral dilemmas, blurring the line between human and animal, and revealing the powerful, often violent, survival instincts that lie dormant within us all.
