This is a DAMN good one, going straight (gay) into my favorites. It manages to tell the whole thing through such a creative, layered framing device, without ever becoming confusing to read. What a masterfully constructed story, and not to mention the compelling character writing both for the main leads and for the loan shark woman.
Don't know what it is about that artstyle, but it really does it for me. The characters look really cool without any exaggerated design.
Then you might enjoy this other one called Liberta. Read it over on Mangadex. Lord i love that series. Action and good dialogue, but enough whimsy and not taking itself too seriously.
