Cursed Seal of Hell (RobonUzumaki)

A forbidden Juinjutsu, one of Orochimarus hidden techniques. It was only implanted in Sakebu Kanakirgioe. The technique has the advantages of the Cursed Seal of Earth and the Cursed Seal of Heaven, however, it grants a much different appearance. For example, instead of turning purple, the user turns black, and does not look like a mutated human anymore, instead looks like that of a demon, with eyes all over the body. Their hair disappears for the time being, and when activated, the Technique boosts chakra points in the body, making their chakra level higher, and darker. It also reduces pain by giving the user a more resistant body, and the users speed, jutsu, and strength increases almost double by what it was before. As always with curse marks, the user is left body strained, and some muscle tissue can tear.
