Not sure how to describe it. Fairly unique. Serious. The art style made me fear it would just be low-key with people getting KO'ed instead of dying, but nope, it's a serious story.
Starting from chapter 3 there are many huge revelations which change the way this story is framed. One big revelation in chapter 3, and then the following chapters begin to discuss the consequences of that revelation, which are revelations in themselves. (At the time I type this there are only 5 chapters.)
No epic fantasy manga's world has ever come close to the level of the Wheel of Time's world, but, coincidentally, aspects of the fictional world of Tales of Innocence strongly resemble it. If I gave specifics it would spoil chapter 3 on, so I'll just say that they have a similar type of character intrigue and plot intrigue. Ah, it also resembles Angel Sanctuary. I suppose you could say that in some respects in even resembles AS more than WoT, since "heaven" and "earth" apparently exist. But the politics and world-wide scope of the plot more closely resembles WoT than Angel Sanctuary.
My only significant complaint is that the characterization (facial expression, words, action) has failed to make me care about the characters. So far, only the plot itself has made me care about the characters (specifically, a brief flashback in chapter 3 made me really interested in their potential).
