Soon, Yui learns that she is the prospective bride, and she tries to run, but ends up in an abandoned room, where she finds her father's diary and discovers that she is adopted. The episode ends with Yui yelling for help as she was cornered by the six brothers. It is the first day at a new high school for Yui, but she finds it strange that the high school is at night. On their way to school, she notices that all the brothers are different from each other and don't seem to get along. Later at school, Ayato forces himself on Yui and sucks her blood and does not stop until Reiji comes and tells him to take his activities to his private room. Later, Ayato throws Yui in the swimming pool and orders her to say that he is great, but Yui can't swim and begs for help. Ayato then has a flashback of his childhood, and after that, he jumps in the pool to save Yui. He kisses Yui underwater to wake her up and suck her blood, but Yui begs him to stop, and he stops, while telling her he will continue later. At the end of the episode, Yui goes back to the abandoned room to see her dad's diary but finds it blank and is confused. Yui has dinner with the brothers and when she returns to her room, Ayato is waiting here to suck her blood. Later, she eventually learns that the brothers are different from each other, since they all have different mothers: Shu and Reiji have the same mother, Ayato, Kanato and Laito are triplets from another mother, and Subaru has a different mother.

After Yui grabs Shu's hand, an old memory comes into his head. When Shu sees that he held Yui's hand tight, he drags her to the tub and says he wants to suck her blood (possibly to make her hate him so she's not too attached to him). Yui is shocked to think he was different, but he tells her he's a vampire. Later that night, Ayato also tries to suck Yui's blood, but is annoyed to find bite marks on her neck. Ayato challenges Shu to play darts with Yui as the prize. Shu wins the match and is about to leave, Laito pushes Yui towards him. Yui tries once again in vain to try to contact her father, but is stopped by Kanato, who later decides to hide her backpack on the roof of the school as "punishment" for not bringing him the accommodations that he had asked for. As Yui goes to retrieve her belongings, she stumbles upon Laito, who seems to be citing strange words to the moon. Laito catches her so he sucks Yui's blood and realized something strange about her blood. Yui later tried to call her father but no use, before fainting on Laito. Later on, Yui wakes up unconsciously and go to the church to pray for help but got trapped with Laito. Laito begins harassing her for his own enjoyment.
