Yu Yu Hakusho - Season 2 Episode 14 Crushing Revenge

Kurama is unconscious, and getting beaten to death by Baken. The announcer Koto tries to give a 10-count to stop the fight, but Baken ignores her and kicks her out of the ring. Just as Baken is about to kill Kurama, the team captain, Risho, tells him to stop. As it turns out, Yusuke was about to fire his spirit gun right at Baken if he had tried to kill Kurama. Kurama then is tossed out of the ring. Baken is declared the winner. Yusuke then gets onto the ring to confront him. Baken uses a technique built from his sweat to cover the entire arena in mist, so Yusuke won't be able to see now. Baken delivers a few blows, but the barely harm Yusuke, and he then fires a spirit gun through the arena, causing the mist to vanish.
