DelinquentsLink to this section
DiU Delinquents.gif
These four delinquents are seniors at Josuke Higashikata's school known for walking around Morioh bullying freshmen. They demand that Koichi Hirose and Josuke greet them as part of the "the rules of school" or they would end up in the hospital just like three guys who previously refused to do it. When Josuke ignores them because he was busy trying to conquer his fear of reptiles by getting close to a turtle, one of the delinquents grabs the turtle and throws it away, smashing its shell open. Josuke was trying not to attract attention and even apologizes, but decides to retaliate after one of them mocks his hair. He immediately uses Crazy Diamond to punch the guy's face, "fixing" his nose into a different shape. The delinquents then run away in fear of getting beaten up.
  • In the live-action film, they demand Koichi to pay them 5000 yen if he wants to pass the alley to get to school. Koichi turns back but another delinquent corners him and says turning back means he has to pay 10,000 yen (he beats one of the delinquents up and heals him afterwards just like in the anime and manga, but heals his face properly).
  • They are generic enemies in Diamond Records.
