It was fine. I've seen the concept of barrier magic OP MC, and I've seen the concept of an OP MC that is obviously necessary but still somehow got banished for some reason, and I've seen the concept of the OP banished MC strolling around and collecting women. The only thing noteworthy about the MC is that he actually cannot use his barrier magic offensively. Usually when a character has a cracked skill that everyone dismisses, it just so happens that the MC's cracked skill can be used for just about anything in universe. That's not how it works here, though. Ohter than that, theart is also very good. The design of the MC and other characters is a breath of fresh air compared to the standard shounen art-style. It's a mix between more adult shounen like tokyo ghoul and a seinen. The writing and characters are nothing to write home about, but the dynamics are fine and sensible. "I really want to kill you at some point, but I'm perfectly fine with waiting" allies are really fun when done right. The MC's lack of libido is sort of annoying. Every single character in this story manages to be more interesting than the MC. It's like one punch man.
