Virtua Fighter - Season 1 Episode 13 Arena of Darkness

Akira and the gang travel further through the subway tunnels and discover a secret underground fighting arena and casino. There, they are captured by Clyde, the organizer of the establishment. Clyde strikes a deal with Akira and Jacky promising he will free them and take them to Sarah if either of them agrees to fight in the ring. For Sarah's sake, Akira volunteers after knocking out Jacky, preventing him from fighting and risking his own life. Akira squares off against Wolf Hawkfield, the champion of the arena. Akira doesn't do so well at first, but Pai reminds him of the Eight Stars and he wins. Being a good sport, Wolf congratulates Akira, then Clyde betrays them.
