Katsuya Jonouchi was blackmailed into rejoining Hirutani's gang. The henchman disliked Jonouchi, but kept quite about it, as it was Hirutani's decision to bring him back.
He picked a fight with a man outside the American Club, after the man accidentally stepped on his foot. The gang was then spotted by Yugi Mutou, Hiroto Honda and Anzu Mazaki, who were searching for Jonouchi. Yugi pleaded with Jonouchi to come with them away from the gang, but Jonouchi denied knowing Yugi. The henchman got fed-up listening to Yugi pleading with and punched him.
Later at J'z, he noticed Jonouchi was staring at him and remarked on how Jonouchi had been acting strange lately. Jonouchi stood up and told the henchman that he could never forgive him for hitting his friend and punched him hard in the face, prompting a fight between Jonouchi and the rest of the gang. The henchman was knocked out in the fight.
While searching for Jonouchi, Honda found the henchman at J'z and demanded to know where Jonouchi was, but the henchman was still unconscious and did not respond.
