Kuro no Utahime

In a peaceful kingdom, the country is governed by the five royal sisters who are also mystical songstress. The gentle oldest sister - the diva of the earth, the second sister who is also the leader of the knights - the diva of the fire, the third sister - the diva of the light, the fourth sister - the diva of the water, and the fifth and youngest sister - the innocent diva of the wind. From generation to generation the divas sing the song of peace, leading the nation against the power of the devil. But a man resurrected from the grave. And along with him, the shadow of many demons appear at the peaceful kingdom. Against the hord of demons, the diva of light serving as a guardian of the kingdom sings, and all demons disappear in an instant. The revived man who saw that demonstration of power gets startled. "If I get that power... I can dominate everything!" And beside the man, the figure of a succubus arises. And so the man who is the revived demon king began to move in order to dominate and rape them all.
