Four years ago, Kazuma Kannagi was defeated by his cousin Ayano Kannagi for the right to be the successor of Enraiha, a sword passed down in the Kannagi family. His defeat, along with his lack of talent for En-Jutsu, the fire arts, the Kannagis’ specialty, resulted in his banishment from the family. Now, Kazuma returns as Kazuma Yagami, a skilled master of Fū-Jutsu, the wind arts.

Shy Natsu awakens as part of a group chosen to ensure the survival of humanity. Together, they have to survive on a changed Earth.

Witchblade is an anime series based on the American comic book by the same name. Instead of an adaptation of the original story, the producers decided to create an entire new setup, with all new characters. This co-production between Japanese studio Gonzo and American publisher Top Cow, who owns the rights for the Witchblade franchise, was licensed for release in the United States. The English dub premiered on the US cable network IFC in January 2008. The show aired on Tuesdays & Wednesdays at 3:30 AM ET, and the series finale aired on June 13, 2008, on IFC. The show is also available on a purchase-to-download system on Xbox Live and PlayStation Network. The first twelve episodes are also available for download via Amazon’s Unbox service. The show is also available on Netflix Instant Stream. As of June, 2011, it was available free on Hulu.

As of December 2008, in the USA and Canada there were 6 Volumes on DVD available, with Vol. 1 having been released in September 2007. There is also a full boxed set containing all 24 episodes and an extra disc with special features. A Blu-ray box set was released on November 3, 2009.
