EDIT: ARAI Niboshiko, the BL mangaka is NODA Ayako, the seinen mangaka. :) So Noda sensei is also a BL mangaka!!!!! -- https://www.mangaupdates.com/author/ggp1egq/noda-ayako

ARAI Niboshiko, the BL mangaka is NODA Ayako, the seinen mangaka (the creator of 'Double', which is also in this list). https://www.mangaupdates.com/author/ggp1egq/noda-ayako

The art gives a little bit of this vibe in a retro sense, but we'll see in later chapters. Also, I think the mangaka's style 'll be chiselled.
Edit: ok, so I checked and this is the latest story from the mangaka and the style is more or less different from their previous works. So: 1) it's an intentional change due to the yakuza & tattoo (tough guy) theme or 2) mangaka's style is simply changing.

I know, I know, this might be an odd title to include here, but some characters are (maybe) drawn like shounen boys and frankly, the story could be targeted at a more general audience as a 'youth manga' with both shounen and shounen-ai undertones. But that's just my two cents.
