I followed this manga for a bit, and I even read abit of the novel for a while. Though I gave up on the novel when he met his old friends again, basically what happened last chapter. I just don't like the whole hiding ones own power thing. Just never sits well with me. That and he's got Schnee who obviously loves him but he does nothing about it.
Overall, a pretty lame MC. Neat world and game mechanics / stuff, but I don't think I like the manga / novel enough to keep trying.
