The Delinquent (不良 Furyō) is a character in the Yu-Gi-Oh! manga. He is a member of a trio of 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. The delinquent played the part of a victim being attacked, by the other two, who allowed Hanasaki to believe he broke up the fight.
Agreeing to create another scene, where Hanasaki could play vigilante, the delinquent threw a rock with a message through Hanasaki's window. The message falsely claimed they had kidnapped Yugi Mutou, prompting Hanasaki to come save him. However his father was unable to meet their price demands, so the three thugs 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, he left a trail of spray paint, starting at a cigarette butt, one of trio had dropped. As the butt burned away, it acted as a fuse. After the paint caught fire, it created a maze of fire, leaving the gang dash out and jump into the water.
