Blood Moon, the night that changed Yui Komori's life forever. Twelve vampires in the same room as her that night, a wicked plan brewed up by Karlheinz. They were all so wild, cruel, hungry, and sadistic...Yui finally had enough and managed to run away from that god-forsaken house before they could have their way with her again. But their animal-like hunger left an effect on Yui, forcing her to give birth various of times to their children even though they weren't there. But does Yui despise these children? No, they were hers and she would love them till the end of time. Even though they remind her sometimes of that horrid night. Years have passed and when Yui thought she finally had her life together with her adorable children...They come back into her life.
