Yamato has short, blond hair, which is described as being porcupine-like, with a single red streak on the left side. He usually wears a dark grey suit and a black shirt which makes him identifiable as a host.
Yamato is a skilled pickpocket who makes a living off what he manages to steal. However, since he does not quite make enough money by doing this, he works as a host at Club Adams on the side.
Light Novel Volume 1Edit
Yamato bumps into Banba, managing to steal his wallet before attempting to run away. However, Banba is quick to realise what he has done and asks Yamato to give back his wallet. But upon doing so, Yamato reveals he had also managed to get his hands on the photo of the mayor Banba had been given as part of an investigation.
Yamato immediately recognises 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 rumours 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 organisation. Yamato also tells him where the club is before Banba pays him for his information.
Later, Yamato runs into Lin, successfully stealing his wallet from him. Nevertheless, while Lin does not realise what he has done, he does not take kindly to Yamato bumping into him. Lin punches him and threatens him with a knife. After assuring Lin that he will get revenge, Yamato heads to Enokida, getting him to use the stolen wallet to find out Lin's identity. With this information, Yamato contacts Jiro in order to get revenge on Lin by hiring the avenger to punch him.
