There's Akane, the sweet and gentle island leader; Mei, the tomboyish and sporty thrill-seeker; Chika, the bubbly and energetic social butterfly; Akira, the intelligent and reserved bookworm; Yuna, the free-spirited and artistic hippie; Natsumi, the sweet and innocent schoolgirl; and lastly, Emiko, the mature and confident beauty.
The island harbors a bizarre, centuries-old secret: due to a supernatural or biological anomaly, the women of Ushiha carry a fetus to full term in rather than the standard nine months. However, a crisis has struck the island. Due to generations of isolated breeding, the genetic quality of the native male population has severely deteriorated, leading to a drastic drop in successful births.
