As Captain of the Northern Guard in X-Zone's law enforcement, he apprehends unsanctioned mountain bike racers. He mistakenly arrests protagonists Sho, Makoto, and Kakeru, believing them connected to the Illegal MTB Riders' Leader. When Kyoichi and the Leader facilitate their escape, he pursues them, leading to a desert confrontation where Sho defeats him in an Idaten Battle to prove innocence.

Later, controlled by Team X via a Dark Emblem, he challenges Sho again on Earth. Sho defeats him, breaking Team X's control before he is forcibly returned to the X-Zone. Freed, he actively defends X-Zone citizens from threats, rejoining the fight against Team X during the conflict on Imperial Island.

Subsequently, he emerges from a portal on Earth, urgently requesting Sho's help to save the X-Zone. Before he can elaborate, a dark force violently wrenches him back through the portal. His operational jurisdiction is specifically the Northern region of the X-Zone.
