Kenka no Gokui 5

Genji and his victorious G.P.S. alliance find themselves facing down a new challenge by the students of Hosen Academy, feared by everyone as 'The Army of Killers.' The two schools, in fact, have a history of bad blood between them. And the simmering embers of hatred are about to flare up again, burning away any last remnants of the truce they had so rigorously observed until now.

Shinji and Masaru spend most of their school days harassing fellow classmates and playing pranks. They drop out and Shinji becomes a small-time boxer, while Masaru joins up with a local yakuza gang. However, the world is a tough place.

Despondent over the closing of his karate school, Cobra Kai teacher John Kreese joins a ruthless businessman and martial artist to get revenge on Daniel and Mr. Miyagi.

Nick and Ruben are hoodwinked into a "shootfighter" (no-holds-barred, to the death) martial arts match by the evil Mr. Lee, who has a grudge against world shootfighter champ(and teacher of Nick and Ruben) Shingo.

Kai—an outcast—joins Oishi, the leader of 47 outcast samurai. Together they seek vengeance upon the treacherous overlord who killed their master and banished their kind. To restore honour to their homeland, the warriors embark upon a quest that challenges them with a series of trials that would destroy ordinary warriors.
