Miyu Yamano is a girl who appears to be 13 or 14 years old, but in fact, she is much older, being a vampire. Even though she is a vampire, Miyu isn't harmed by sunlight, holy water, or crucifixes, and her reflection can be seen. Though she does need to drink blood to survive, she chooses her "victims" carefully. She chooses people who have suffered a tragic loss, and offers them their greatest wish—to be with their lost loved ones, at least in their dreams—in exchange for their blood. These people live an endless dream state forever.
