Yamato immediately recognizes one of the people in the photo as a host for Club Miroir, who was killed in his apartment along with his lover. He then explains that there are rumors going around that it was the work of a killer, who had been sent in to kill the host for stealing from his employers. Yamato goes on to tell Banba that Miroir is not only a high-class club but a dangerous organization. Yamato also tells him where the club is before Banba pays him for his information.
Later, Yamato runs into Xianming Lin, successfully stealing his wallet from him. Nevertheless, while Lin does not realize what he has done, he does not take kindly to Yamato bumping into him.

Niwaka Samurai Imposter Arc
Yamato joins the Tonkotsu Nine in a practice game in early summer, where he protests Genzo's suggestion of a punishment game based on base runs due to being a sacrificial bunt hitter. Lin's penalty from his poor performance on defense saves him, and during the team's pre-tournament get-together, he, Banba, and Jiro are the center of the party and get drunk quickly.
He introduces Lin as a hostess at Club Eve as a favor for Banba. A few weeks later, this backfires on him when Lin threatens to ruin his name by messing up badly at the hostess club in order to blackmail him for a favor. Unable to let Lin destroy one of his careers, he begrudgingly accepts Lin's request to steal money back from Abe and Yamamoto.
Some time later, he bumps into Abe and manages to take his wallet, but it does not contain all the money Lin had requested. After Jiro and Misaki paralyze Abe and José Martínez rams his vehicle into the pair's white van as part of his avenger mission, Yamato walks up to Yamamoto lying on the ground and brazenly takes the injured man's wallet, to the disgust of his friends looking on.
