So. Just why did kakashi hide his face anyway?

Because if they see his face the world will explode. ╮(￣▽￣)╭

maybe because it's better for a ninja not to be recognisied?

Because he was a part of the anbu and even without that a well known ninja but i don't think that that was all too good for him so he hide his face

But before he was anbu he also hid his face... I think he was just born with the mask on.

Haha yeah maybe ^_^ kishimoto must have liked him better with the mask on because it makes it misterious
