it probably wise if it wasnt mentioned at all. Why should Pain has anything to do with the 6th element. Sure, pain has mastered them. But if the sixth element is anything but on the same level with the other elements, then it should belong to a different class. I also explicitly mentioned that void is a posibility, but void is way too out there for me. If you ask me I can create nothing out of nothing anyday. j/k. Oh Light is off, please explain why, not that it has to be Light as I already said.
Killing time while waiting for the next chapter. OnePiece, that is.
