I am a being even more ominous than the Nine-Tails - the Zero-Tailed Jinchuuriki, who feeds on the negative emotions of the world. Konoha regarded me as a curse and imprisoned me secretly for ten years.
Until the Kyuubi went berserk, I took advantage of the chaos to escape, and became a ghost wandering in the darkest corner of the ninja world. I feed on fear, hatred and despair, they are a curse and the source of my strength...
It didn't look very happy to me.
