This is one of the strongest of Orochimaru's cursed seals, the other being its counterpart: the Cursed Seal of Heaven. It was given to Kimimaro. The seal consists of three slightly curved lines, which spread in a square pattern.
When the second level of the seal is active, Kimimaro takes on a dinosaur-like appearance complete with a tail. Several large bones also protrude from his darkened brownish-maroon skin. Like all cursed seals, Kimimaro receives increased chakra levels and physical capabilities when the seal is active.
