Sacred Haven of Debauchery

Mold, the main point of this quote was somewhat different: to highlight another topic where the strength of characters is discussed, how absurd it is (there are interesting discussions sometimes, but not often), and what ridiculous posts can be found.
Regarding plagiarism - maybe. I could give an unpleasant example, if I said that covers of songs are often better than the original, but I won't, because I haven't watched One Piece yet.
In general, it's difficult to judge such things. Maybe the author blatantly plagiarized with a selfish motive, thinking that such a character would definitely appeal to readers. Or maybe he was simply inspired.
