A touch of seinen/noir artwise. The artist's style (check out their Xtter) is heavily influenced by noir and seinen themes (tough guys, gangsters, blood, dark colors, dark themes, tragedy, violence, etc).
On NovelUpdates, the source material (novel) is continuously compared to Omniscient Reader’s Viewpoint -- like in every single comment. --> I've never ever read stuff like that, so concepts like 'constellation' and 'contractor' are new to me.
I put it here bc I freaking love it! It's a very smutty 18+ BL.

Taiwanese BL.
Elegant noir yakuza/businessman style? Call it how you want. :) -- Evidence: https://tangemichi.com/intelligence/gallery/
Also my rant: 10 f*cking volumes and it's not licensed?!

------------
Maybe it'll be removed from this list, but based on the artist's Xtter account, they are really into manly men + noir/seinen/shounen style.
One of the best omegaverse BLs I've ever read.
Looking at the mangaka's Pixiv and Xtter accounts: heavily infulenced by seinen and shounen + they are also a JoJo and Golden Kamuy dj mangaka.
It's the manwhaka's first BL, so far they have published seinen and shounen stories.
Also after checking out their Xtter account: they are a big fan of retro Japanese seinen/shounen anime/manga (e.g., Berserk, Ghost in the Shell, Dragon Ball, Akira, Elfen Lied, Slam Dunk). They also like Western superhero comics and M/M fanart (e.g., SuperBat).
