Space–Time Hole

The Black Hole is negative space that can swallow everything around it. It can only be summoned by a member of the royal family in the chamber where the Book of Gelel describes, by offering a small amount of the member's blood, in order to destroy the Vein of Gelel, but the summoner will also die, as nothing that has been sucked into the black hole has ever came back out alive. Temujin summoned the black hole to seal the Vein of Gelel, at the end of Naruto the Movie 2: Legend of the Stone of Gelel. He was ready to accept his death, but Naruto saved him from being sucked in as well.
