I ran across this manga on another site, and read a few chapters since the premise sounded interesting (guy is able to put stuff in his item box, sell it virtually for points, and use the points to buy modern stuff).
The art is atrocious. As individual pictures it looks fine; some of it is even good. But it does a horrendous job conveying action. There will be a bunch of pictures depicting combat, but you have no idea what's happening. I had to drop it because it hurt my head trying to decipher the story.
