The anime is already out, they even announced a second season, which surprises me since its animation was a rather disappointing flop. Nothing like what many claimed was going to happen. However, it seems that this didn't matter to them since in Asia it seems that they liked it a lot and it was successful enough to warrant a sequel. To watch an anime that is just moving images with basic computer-generated visual effects, I'd much rather read the original work (even though I don't read manga or manhwa).
