The main premise of an MMORPG had me fooled. I had expected this to be an action manga, but it isn't. (There is some action, sure, but it certainly is not the main focus.) It is a manga that deals with the psychology of its characters who live in a world where basically everything can be done virtually.
Basically, it deals with virtual counseling on an MMORPG.
With a premise like that, it's surprising how gripping this manga turned out to be. From what I've seen, the mangaka is very good at fleshing out characters. The main character could have easily fallen under the trope of "tall and stoic antihero". But, the mangaka makes him so much more than that. With each arc, his personality is developed more and more, and his encounters with others truly do affect and change him.
The only criticism I have now is the way the mangaka simply throws you into the world. While I do appreciate the "showing not telling" form of storytelling, I feel the manga could have benefited from some explanations of basic terms used, such as the concept of "Board"s, etc. Of course, as long as the reader pays attention, all of these terms can be deduced, so it isn't a particularly confusing. (But I would've still liked some explanation, if only to streamline the story a bit.)
Regardless, while this manga is certainly not for everyone, it is certainly worth checking out, even if only for its unique take on a common premise.
