린월, 燐月 ～リンゲツ～ THE ANIMATION

A long time ago, there was a family named Rindo that was cursed by a monster. As a result, all newborn babies in their lineage have been girls. To lift the curse, they needed to marry someone from the Higetsu family who possessed strong spiritual power and give birth to a child before the next red moon. Now, the curse has fallen upon Rindo Naoto. In order to break it, he must father a child with one of the four sisters of the Higetsu family.
