Asteroid Yamatoman While most of the Asteroid navis we've seen so far have been repeats from the original series or Axess, Yamatoman is a surprise all on his own. Laika's good friend Iriya travels to Japan for a fencing tournament, and becomes interested in what else, but ancient samurai artifacts. So much so that he begins to use Yamatoman to steal them. Laika and Netto must confront Yamatoman head on in order to stop the thefts, while Iriya must realize the true meaning of his friendship with Laika before it's too late to turn back.

Yamatoman is one of the more ruthless Asteroid navis we've seen, and highly skilled in combat.
