About
Naiko and Guest are siblings. Naiko is a normal human, but Guest was born as a vampire. (Guest is a peerless beauty.) Their parents put Guest in an institution to keep her away from Naiko. However, the two ended up meeting at high school. Vampires can only drink the blood of the opposite sex!
Characters
Guest's older brother (11th grade). His parents never told him he had a sister, but he knows. He doesn't understand why they won't let him see her. Since he used to look at photos of Guest when she was young, he recognized her immediately at high school.
