Okay let me first give a disclaimer that this manga is basically for a mature audience completely. Not that it's constantly involving mature themes, but rather dealing with concepts that are distant from the innocence that you would expect from modern anime & manga.

I read this via Crunchyroll manga, and after about 10 chapters I ordered the Japanese manga.

The story: is about Gohongi, a man in his mid-twenties without any real family left, moving back to his hometown, working and living at a movie shop in chinatown. He suddenly gains new roommates to later find out they are all involved in the mafia named "Lovely Hometown". One of the new roommates, is a fifteen year-old girl named Mei which Gohongi constantly tries to convince to try a new lifestyle. He eventually steps too far into the mafia life and ends up involved. He is constantly struggling with the concept of death, and worries for Mei while she finds solace in hanging around Gohongi.

My opinion: Although at 23 chapters and 4 volumes, this series was somewhat brief, I am astonished at the character development. In both a good way and bad way. I say this, because later on certain characters make decisions which seem rather "out of character". I mostly enjoyed it regardless, because it made everything more suspenseful. I thoroughly enjoyed the manga and am very surprised at the lack of general attention this series has received. There are some parts that kind of made me uncomfortable, but I was able to get through it. The ending left me sad and slightly confused, but it was also beautiful and I don't think I will read another manga like this in a long time. I imagine this will eventually become a cult hit.
