Black Tessaiga

 or Kuroi Tessaiga as it's more commonly known, is the only InuYasha OVA. It was showed on July 30, 2008 in Japan as a 30-minute Inuyasha feature titled Kuroi Tessaiga screened on Takahashi Rumiko's picture exhibitions across Japan.

In January 2010, this special ended up, slightly edited, as episode 15 of Inuyasha: The Final Act.
