"It was my influence that caused the endless war. It was my influence that lead to her stealing its fruit. It was my influence that caused her child to change the world. It is by my influence that I will rise again."
— Rengokuki
Rengokuki(煉獄鬼, Purgatory Ghost,) is an ancient spirit, hiding under the guise of a tailed beast, going under the name Zero-Tails (零尾, Reibi). Appearing as a Noh masked leech-like spirit sealed within the Land of the Sky.
Despite the beast referring to itself as Zero-Tails and Shinnō referring to it as a tailed beast, it is not really one of the original tailed beasts due to the fact that it was not born from the Ten-Tails.It's also noteworthy to comment that, during the movie, when the Zero-Tails latched onto Naruto, the Nine-Tailed Demon Fox reacted aggressively to its presence and attempted to expel it.
