Vampire Princess Miyu

Miyu  (美夕)  also known as Miyu Yamano (山野 美夕 Yamano Miyu), is a beautiful girl who appears to be 13 or 14 years old but in fact 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.

In the OVA, she is the child of a human father and a vampire mother in post–World War II Japan. In the TV series, on the other hand, her mother is human and her father is a Shinma guardian in pre-World War II Empire of Japan. In both cases, Miyu becomes the Guardian (also referred to as the "Watcher") after losing her parents.

When Miyu was about 14 years old, she found out that her father was a Shinma from her human mother. (Prior to that, she was told that her father died but kept in conviction that both of her parents were human.) Depending on the version as Manga, Ova's and TV series, Miyu either herself wanted to know the truth, or came to know it when the time of the awakening came. The fate of her mother is also different depending on the medium as in TV or Ova's both her parents are killed while in the manga her mother merely forgets about Miyu's existence, while most other people generally do forget about Miyu's existence as she loses her status of a human. This leads Miyu to consider her fate as more of a curse. She often feels incredible sadness and loneliness prior to meeting Larva (Lava).
