Kenshiro attacks Toki, who is surprised by his speed and power, but still manages to immobilize Ken. Fortunately, Rei and Mamiya arrive to help Ken, revealing that "Toki" is actually an impostor named Amiba, who is a jealous rival looking to destroy Toki's reputation. Amiba gloats that he is a genius and has imprisoned Toki, but Ken defeats him with a Hokuto Shinken technique that forces him to walk off the roof of his fortress. Before he dies, Amiba reveals that he is following orders from a man known as "Ken-Oh".
