Ringetsu - Season 1

A curse was placed upon the Rindo family long ago, ensuring they would only produce female offspring. This condition can be temporarily suspended by conceiving a child with a member of the Hizuki family, though the curse reactivates every third generation. The current bearer of this burden is Naoto Rindo. With his original Hizuki fiancée deceased after an accident, the time to act is limited. He must now attempt to impregnate one of the four remaining Hizuki sisters with a male heir to avert the curse's return.
