The story isn't so bad (the MC is really dumb, but other than that, it's OK), but damn the art is shit.
Just look at how the necklace was drawn... it looks more like a storyboard than a finished and published manga.
It's one of those rare instances where the art is soooooo bad, that I think I'd rather read the novel.
I mean, check this shit out... the first one is the cover of vol.01 of the manga.
And the second one is a similar cover for volume 2 of the novel drawn by Nardack :
And that's the fucking cover, where artists spend extra time to make things better.
By the way, the mention of Nardack on the cover of the manga is for "Character Design", because the other crap artist didn't even think of the characters, but just butchered the design from someone else.
