Ten Fighters Of The Underworld
Gaia sends them out to find Gin, the dog who is able to perform Zetsu Tenrō Battōga, and also to find Reima's palace. On their way looking for information, they kill Bill and Bemu and also wound Hakurō badly. They find Reima's palace after the trainer Noroi tells them. Mugen almost kills Noroi and sends his fighters to Reima's palace. They are stopped by the blind gatekeeper, Mukonga. One of them, Thunder Wolf, challenges Mukonga and both of them died in the battle.
Right after Reima and his Hakkenshi arrived, they easily defeat the fighters. Their leader Mugen escapes and is never seen again.
