As the sole human living alone with six handsome vampires, beautiful young Yui Komori is slowly becoming used to being the constant focus of all of their attentions, both amorous and otherwise. However, if she was feeling pale and weak before, her ordeal is about to become even more emotionally draining as four new vampire brothers appear with the intention of making Yui their own permanent dinner guest. Who are the Mukami brothers, and why are they so dead set on keeping Yui for themselves? Why do they keep referring to her as "Eve" and whose master plan are they following? How will the original six Sakamaki brothers react to having Yui stolen out of their clutches?
