It just bugs me how repetitive the mafia involvement plot lines get in this genre, it is in virtually in every single one and when it gets there it does it in the most stupid or unnecessary ways.

Loved your analogy, I didn't think it that way before but 21 jump street × fight club fits it really well. I'm probably gonna start using it to describe it lol

One last thing just in case you get somewhat interested, the korean delinquent manwhas are a completely different genre from the manga ones. Like, manga is usually more romantic about the figure of the delinquent, it also treats it as a weird in between of the worlds of adults and teenagers, stories usually show the protagonist as a noble delinquent. Manwhas are more like trashy entertainment, there is an absurd amount of bullying going around, lots of them are revenge stories from weak to OP, here the protagonist s usually act vigilante-like, and the fights are usually phenomenal, it feels like it is the biggest focus on most works and most manage to make shonen tier pacing of fight after fight being entertaining.
