Yui Omori has always been able to see ghosts, and all sorts of weird things happen around her. She has been abandoned by her priest father, who convinces her to go live in the house of an old acquaintance of his, the Sakamakis. Vampires are taking blood from the students in her new high school, and the suspects are the six Sakamaki siblings that Yui will have to live with in the boarding house. As she she spends more time knowing them more, she discovers a shocking secret inside her body.

** Shuu, [[spoiler: a ExtremeDoormat since childhood, one day befriended an human boy named Edgar. Both became best friends, but Reiji, disapproving his brother being friends with an human, burned the whole village Edgar lived in, leaving Shuu traumatized and feeling useless upon not doing anything to save Edgar. The nail in the coffin was Reiji twisting his mind by constantly telling him that because of his failure, he is not apt to be the family head.]]

** Laito, [[spoiler: often having sex with his own mom, due to her being an EthicalSlut. He growed up believing she loved him and got jealous of all the men she screwed. When Karl found out the relationship between Laito and Cordellia, he locks up Laito in the basement prison and when Cordelia came to see him, she has sex with Ritcher in front of him, traumatizing Laito and becoming a sexual deviant.]]

** Shuu, [[spoiler: a ExtremeDoormat since childhood, one day befriended an human boy named Edgar. Both became best friends, but Reiji, dissaproving his brother being friends with an human, burned the whole village Edgar lived in, leaving Shuu traumatized and feeling useless upon not doing anything to save Edgar. The nail in the coffin was Reiji twisting his mind by constantly telling him that because of his failure, he is not apt to be the family head.]]

* Jerkass: All of the Sakamakis, but mostly Ayato.

* Bishonen: The Sakamaki siblings.

* {{Kuudere}}: Shuu. The emotions were always there, deep down; he just never had anyone to bring them out because nobody except for Edgar, who died shortly after has ever bothered to treat him like a person instead of the family heir.
