I absolutely love this manga and mangaka. His work reminds me of the films by Takashi Miike, or the novels of Ryu Murakami (particularly Coin Locker Babies). If you enjoy surreal, ultra-violent, atmospheric seinen, then this should be in your wheelhouse. It also happens to be hilarious (in a very dark way).

Upon first blush, the art may appear unimpressive, with its unpolished, sketchy style. However, I feel that this is what gives the manga it's unique feel. Within a few pages, you can see that the artist has a distinct artistic sensibility, and is an intensely talented storyteller, with the movement flowing seamlessly from panel to panel. His character expressions are also on point and hilarious. The only knock I'd have against him is that he tends to draw the female characters similarly (they're all cute af, which might be a pro). All in all, I really respect mangaka's who are able to develop a unique style that is immediately recognisable. Artists like Inio Asano, Hiroaki Samura, Q Hayashida, or Junji Ito come to mind. Its a big reason I can't stand shonen or shoujo manga. The aesthetic is so strongly associated with the genre that artists rarely feel they can deviate from it.

You really need to have an affinity for a particular type of seinen for this manga to be enjoyable. This is not your typical manga.
