The Juinjutsu is a very powerful one, and grants many immense abilities to its' user; at the gradual cost of their sanity. When the cursed seal is active, it transforms the user into something that hardly resembles a human being–a true demon. The most terrifying ability it grants the user is the ability to reattach lost limbs, or seal up injuries quickly without any marks. This regenerative capability is also shockingly present when the Cursed Seal is not activated, making it all the more terrifying.
