I read about 60 chapters over the course of a couple hours and I feel like I have a pretty good grasp on this series enough to review it.
Art: So you can tell the artist put a lot of time into the art and it shows, but something about this style is just unpleasant to look at. Not sure how else to explain it.
Story: Story is nothing to groundbreaking, reminds me of Gantz. There is a lot of rape and stuff like that that this series could do without. Robachan in general is just pointless to have in here at all.
Character: I appreciate that the main character is not some perfect hero, and even messes up sometimes. Nothing groundbreaking though, he's fine.
Overall: 6/10, seems like it tries to hard to be edgy at times, and while I know that the art is objectively good, I just find it unpleasant and messy to look at a lot of the time.
