My list of delinquent, mafia, yakuza, assassins, etc. http://www.mangago.zone/home/mangalist/347760/
Yessss that is one of my favourite things to see!
Here's the ones I have bookmarked:
http://www.mangago.zone/read-manga/apron_yankee/
I read it a while back, former delinquent seme and delinquent uke who looked up to him, finds him working at a nursery(?)

Omegaverse. I'm preeeetty sure the omega is a delinquent and the Alpha is yakuza so bonus points for that! It's complete and the sequel stars the two main pairing's kids so aw.

Oneshot by the same author as Abareno Honey. Uke is a delinquent with lightning powers and Seme is a scientist who wants to "study" him ;).

Again, when it comes to "Yankee" in the title, chances are you're gonna get a delinquent. The Uke is a yankee, who repays a debt to the Seme, who works as a gay porn star. You can guess what happens next. It's now complete!

Omegaverse again! If you're looking for a delinquent, this guy definitely fits the bill. He even wears a face mask. Uwa~ scary! The omega controls his heat through sheer willpower. If only i had that kind of dedication to my grades ( ̄∇ ̄")

Think most fucked up game of cards you've ever played. If you've been anywhere on the site recently, you've probably heard of Caste Heaven. I'm not sure if MC even counts as a delinquent when pretty much everyone in the cast is. (excluding a character here and there) Maybe it doesn't, but if you want an uke who's a sassy little shit, tough as nails, and has an temper shorter then my fingernail, then you might wanna give it a read.
I can't quite think of any manhwa. Peach Love has a cast of delinquents. I don't think mc "Love" is a delinquent personality wise. He does look like one and is generally treated like it though (in thr first chapter some people run from bim cause they think hes one). i think it's been implied he used to be part of something bigger but idk havent read it in a while.
Addiction doesnt have a delinquent mc, but he also has a sick-of-your-shit attitude, if you like that kinda thing.
Anyway I hope you like them! These are just what i have bookmarked, so there's probably some more good ones out there too. I also love that kind of uke, so I figured I'd do a fellow fujo a favour.

Does someone have reccomendations for yaoi's where uke is a delinquent? Piercings, dyed hair, all that jazz.
