He is one of the three top members of the Shachihoko Group.
He faced Dragon Ryu in the quarterfinals of the Duel Carnival tournament and lost. After their boss lost his duel, Rikishi and Shachihoko attempted to break their way into the vault in order to steal the prize card, Prin Prin, the Eternal.
Luckily, Mimi managed to trap them and lock them in the empty vault so they are unable to steal it.
He is revealed to have been manipulated by the spirit of Thrust Sumo, Strongest Yokozuna. He has fallen unconscious while Katta duels against Onsen.
