I just wanted to ask a few questions regarding some minor things that are sorta bugging me, sorta. Contains some Spoilers.

1-Why does Zetsu have the hidden grass tag? At first I was going to ask about this, but I didn't know for sure it was the grass village tag, even though I recognized the symbol, later someone got him on my server, and the tag was indeed, Hidden Grass. As far as I know, Black Zetsu's just a physical manifestation of a certain somebody's will, which they had no ties to any village. and White Zetsu's just a...modified human that's pretty darn old, and doesn't originate from the grass village, as far as I know.

2-I found this while playing around with font color and stuff in the little spoiler thing, with weird colors that make it look repulsive, the colors were in a completely different language. That's right, there's a text bug in the forums.

3-For a ninja to qualify as a Sword user, they have to use a blade of some kind, excluding Kunai and shuriken, right? Normal Orochimaru counts as one, through his snake sword which is used in his mystery, right?...then how come Traitor Orochimaru doesn't count, despite in his full combo standard, he uses a sword to cause high float to an enemy, so shouldn't he also be a sword user? Just...wondering

Edit (1/2/2018)-So...umm...why?
