Now that three of the brothers have found their "Soul Mates," Reiji realizes that their father, Karl Heinz, is sending each brother a bride ... hand-selected. But when his bride-to-be shows up on the manor's front porch in a hospital nightgown and apologizes for her utter lack of manners, Reiji finds his curiosity about this girl goes deeper than a potential test subject. Part 3.

With the Cordelia troubles over and the boys' Uncle Richter gone, Reiji sees no harm in allowing Kimi Kasimoto to stay. Unlike Yui, however, this bride is not entirely human, and she is well aware of the brothers... otherworldly characteristics. How will the brothers fare with another bride in the house? What adventures lie ahead for Kimi? Part One of a six part series.
