Shoutarou Akaboshi

An immature, obsessive watch collector who steals the rare D-Shock watch that Mutou Yugi got for Honda Hiroto, as Honda was going to buy it for Nosaka Miho. Dark Yugi comes to get it back, challenging him to a Game of Darkness, in which the players have to stop the watch after letting it run as long as they can before a pendulum swings down. Despite losing his first game against Yugi fairly, Shoutarou demands a do-over, thinking that he will have an advantage if he plays from the opposite side, which Yugi accepts. His attempt to stop the watch fails because of his not taking account of the pendulum returning from the oppisite side, and he is cut on his hand as a result. Despite having lost twice fairly, Shoutarou refuses to acknowledge his loss, and tries to snatch the watch anyway. At this point Dark Yugi gives him a Penalty Game, making him think he's made out of clock parts. Some time later, Shoutarou returns home and silently destroys his entire watch collection, with his mother desperately begging him to tell her what happened.
