Well... I think it's just the first arc, so after this I don't think they'll for us on them anymore.
┐(´ー｀)┌
Based on the he raws that I can find (not complete, so I can't read it chronologically ( ；∀；)) theyll do other stuff too cuz they're in a different location (probably, I can't read Japanese)
Goddamit

I think the problem lies within the readers. Manga are normally focused towards younger generation. So, a master assassin secretly hiding in the neighborhood, fighting bad guys all day for justice is the normal shounen approach. The psychological dilemma of fable, his struggle to adjust to normal life, boring day to day job, lack of action is the adult literature approach. If I was 5-10 years younger id jump on this manga.
I wanted this manga to be mostly silce of life genre. Like the way it started. A killer in hiding. Enjoying his peaceful life, doing new stuffs his never done before, enjoying his free time. But now its getting more and more about those stupid thugs and their gang trying to mess with mc. especially the ex pornstar girl...meh.
