Delinquent manga is an interesting genre and one of my favorites, there can sometimes be really funny works, like Angel desnsetsu or Kyou kara Ore wa!! , on the other hand there are some that are really good for the fighting Holyland

There are also a similar genre in manwha, although their stories tend to be a lot less romanticized and more about bullying and close ties to adult gangs.

So what are some delinquents manga/manwha you personally like?
