The Sage Art: The Six Paths Curse Mark Seal is a jutsu that immediately bestows the target with a seal that allows the target to enter Six Paths Sage Mode. Not to stop there, if the user has a full chakra status, then they will reach the Six Paths Senjutsu stage. But great power comes with great sacrifice. When the target uses the seal, they become extremely dark, and everything they previously cared about is destroyed. The seal was banned and became forbidden when a shinobi used the seal on themself, and destroyed their own village. The jutsu is rarely learned by anyone, unless they wanted to do great harm. And the user dies immediately after, leaving the target to destroy possibly anything they pleased.
