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?
Yankee-kun to Hakujou Gaaru is one of my favorites. It’s by no means a complex story, but it’s sweet, and it appears to portray blindness pretty accurately.
