Gachin-kozo debuted in episode 138, where he inspirited Katie. Thinking that Gachin-kozo was a challenge, Nate decided to challenge him in the schoolyard. He summons Kyubi, Venoct, Robonyan F, Snartle, Lie-in Heart, and Shogunyan to attack Gachin-kozo. Nate summoned the almighty Lord Enma to finish him off, presumably destroying him.
