A former pro-wrestler, after he hears of his thugs being defeated by Miu, he sends his entire gang out to look for her. The three thugs who were defeated by Miu are seen interrogating Izumi Yuuka and Himeno about Miu's whereabouts when they spot Kenichi and Akisame. The thugs recognize Kenichi and mistakenly believe that Akisame is Miu's father. After Akisame dislocates the joints in the hand of one of the thugs, the thugs call the Wrestling Boss.

The Boss bends a stop sign in a failed attempt to intimidate Akisame, who in turn provokes the boss in to fighting by fixing the sign with just one finger. The Wrestling Boss attacks Akisame who effortlessly defeats him, all the while using him as a training sample for Kenichi, on how to deal with larger opponents. After the thug who got his hand joints dislocated fires a gun at them, Akisame corners the thugs in an alley and easily defeats them in such a harsh fashion that Kenichi said that he never thought bodies could bend like that.

The Wrestling Boss later appears at a race track where he is knocked out in one punch by Sakaki.

When Yomi is dispatched by Yami to hunt dojos across Japan, the Wrestling Boss mentions that his old training ground was burned and along with others, and declares himself allied with Ryozanpaku.

He calls Sakaki "Leather Jacket" and Akisame "Grim Reaper with a Mustache" and considers them monsters.
