Deathtrap Dungeon (Japanese cover)
Sorry about the quality on this one, it's just pulled from a crappy pic on the net - best I could do. I tried to post it as a comment on one of the other covers, but apparently you can't post images in comments.
Anyway. Yep, this is the Japanese cover, LOL. It's like they didn't even read it.
As a side note, anyone who's ever been in a Japanese bookstore can tell you that most novels have this style of anime-art cover. It's often difficult at a glance to tell the novels apart from the manga. But I guess that's what it takes to sell in this country LOL.
