Untitled Episode 7

Yuma is a bit curious about Shu, so he asks Yui what she knows about him. At school, Yui almost falls down the stairs, but is saved by Yuma. He carries her off, only to soon come across Shu who is sleeping in the corridor, so he makes him move by biting Yui. When Yui returns to the Mukami's mansion, Ruki appears and grabs her in order to suck her blood, but he suddenly refrains. This confuses Yui and Ruki quickly leaves. In his room, Ruki is beginning to become aware that he and his brothers may not be able to become "Adam" after all...
