no clue about the novel but the manga is just shit. 21 chapters out as of now and enough story in them to barely cover 1, maybe 2 chapters. fights drawn out to no end (think dragon ball z style), a TON of narration and self-introspection (that no one ever asked for). overall, just an overblown, overly-complicated and drawn-out manga that will most likely need 100 chapters just for the idiot MC (and i'm not being sarcastic) to make it to the second "day". read if you have nothing to do and like going through chapters in seconds rather than minutes
