Liked the premise and setting, but the story deflates almost inmediatly and the characterization is quite edgy bad. Would be nice if the author stops forcing creepy faces to give out their personalities or intentions.
"Oh wow, that lady over there with the grin or being extremely polite or helpful with no reason looks suspicious, let's see how this goes. It's not like I've read dozens of mangas with the same character whatsoever". Then in the next panel or page she does an edgy creepy faces and confirms it. Come on.
