Kakashi Hatake, a shinobi from the village hidden in the leaf has always hidden his face behind his mask but recently in a Naruto exhibition, which officially opens today in Japan, had a guestbook which finally revealed his face (i think).
It hasn’t been confirmed yet on whether or not its real but honestly I don’t think anyone actually cares anymore, instead now a whole new question arises…why the hell was he hiding it in the first place
