Blood+

Blood+ is a Japanese anime television series produced by Production I.G and Aniplex, directed and written by Junichi Fujisaku. The series was broadcast on MBS and TBS from October 2005 to September 2006. It is licensed for international distribution in several regions through Sony Pictures Television International (SPTI). Blood+ was inspired by the 2000 anime film Blood: The Last Vampire, though there are only a few allusions and basic elements from the film. The series is initially set in September 2005 in Okinawa City, where the protagonist, Saya Otonashi, lives as an ordinary schoolgirl with amnesia. Her life is disrupted when she's attacked by a Chiropteran, a bat-like creature, and learns she is the only one who can defeat them. Armed with a special katana, Saya embarks on a journey with her family, friends, allies, and her chevalier, Haji, to eradicate the Chiropteran threat and recover her identity. The journey reveals the history of the Chiropterans and Saya's mysterious past, which extends to the mid-19th century. The series has aired in multiple regions internationally, including on Cartoon Network's Adult Swim in the United States.
