Well, just saw this several days ago:
courtesy of the anon who provides us this.
I don't know whether all covers are suffered from the wrong bending/folding, but at YenPress' site someone who's called Bweb confirmed that all covers are like that. It's quite unfair for the people who were still willing to buy the magazine to get the cover only. What is the meaning of this? Can someone else confirm that's really the truth?
