I love a manga that can really put me into the setting, and this one is the world of Yakuza in Tokyo in the '80s through the eyes of a wonderfully slutty, damaged, adorable, and complex male prostitute. The storyline is so interesting and dark. The art is sexy and aesthetically pleasing. Overall, I'd love for this to be made into an edgy, artsy anime... Just so badass.
