InuYasha

Sesshōmaru wants to see if Inuyasha is worthy to wield the Meidō Zangetsuha, so he challenges him to see if he can take the technique he worked so hard to master. Naraku decides to make use of Sesshōmaru's hatred of Inuyasha by giving him a familiar unfair advantage, hoping the fight will end with Inuyasha's death. Black Tessaiga or Kuroi Tessaiga as it's more commonly known, is the only InuYasha OVA. In January 2010, this special ended up, slightly edited, as episode 15 of InuYasha: The Final Act.
