This is one of the strongest of Orochimaru's cursed seals, the other being its counterpart: the Cursed Seal of Heaven. This cursed seal is particularly strong even amongst the other already powerful cursed seal with Kimimaro being the only known user. It consists of three slightly curved lines, which spread in a rip-like pattern. The seal is located of the upper portion of Kimimaro's chest over his manubrium.
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 skin. Like all cursed seals, Kimimaro receives increased chakra levels and physical capabilities when the seal is active.
