The story is not bad, but it is not good either. It had a lot of potencial but the author was incompetent at making the most out of it. The main problem is the pacing; while it starts off well, the story quickly falls short and starts to drag at some points. Then there is the problem with girl's power that seemed like it would a big deal but the author clearlly did not know what to do with it and made some excuse to discard it. To make things worse the art is just a small step above amateur tier, most panels have no background either. The characters have their reasons but it feels like they accepted everything too easly, especially the MC. All in all I would say this is worth a reading, since the 71chapters are not dense at all and could be easily shortened to half of that.
