The art for this is almost good. The coloring and atmosphere are rendered with some level of skill, but faces and bodies tend to warp. Like they don't have a totally solid grasp on anatomy or their character's designs yet. The demon lady is actually drawn the most consistently. This is something that tends to improve as they draw more chapters and find a comfortable way to draw though, so hopefully that will be the case here.
As for the story, it's still too early to judge but it looks like it's going SAO bloody mode.
