The Delinquent (不良 Furyō) is a character in the Yu-Gi-Oh! manga. He is a member of a trio of grungy youths who, were paid to stage scenes of violence that Tomoya Hanasaki could break up.
The delinquent and two of his friends were paid by Hanasaki's father to create false crime scenes and allow Hanasaki, dressed as Zombire to fight them off. At first he and one of the others pretended to attack the third in front of Hanasaki. When Hanasaki intervened, they pretended to attack him, but deliberately fell back, pretending to have been hit, when he flinched.
The next day at school, he and his friend that had pretended to fight Hanasaki questioned Yugi about knowing Hanasaki. However Hanasaki arrived and told them to leave.
When Hanasaki's father was unable to meet their price demands, the three attacked Hanasaki and revealed that his father had paid them to let him beat them earlier. Dark Yugi then arrived to save Hanasaki. As the gang chased him, one of the trio left a trail of spray paint, starting at a cigarette butt, the delinquent had dropped. As the butt burned away, it acted as a fuse. When the paint caught fire, it created a maze of fire, leaving the gang dash out and jump into the water.
