Sidenote, in response to those mentioning the manga. Not quite accurate...
There is not only one, but three different manga based on Blood+ mythology being published by Kadokawa Shoten.
* The official adaptation of the TV series, by Kumiko Suekane, serialized in Monthly "Shonen Ace".
* A story focused on Saya and Hagi's past in Russia, by Asuka Katsura, serialized in "Beans Ace".
* A Hagi solo story, prior to the events of the TV series, by Hirotaka Kisaragi, serialized in "Ciel".
