Hiroshi (ヒロシ) claims to be part of the Dollars. He first appears in episode 3, when Izaya trashes his girlfriend Youko's phone. Izaya shaves his head with his flick-blade, and he and the girls flee. A short while later, when Izaya is facing off with Shizuo, Hiroshi appears with an armed group who claim to be members of the Dollars. He and his fellow thugs instigate a fight with Shizuo and are easily beaten.
An image of him is shown in episode 15 on a cover of the tabloid Tokyo Warrior with Takeshi.
