Black Tessaiga

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

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