Concept idea:-
Little is known about Jashinism in the Naruto universe, and what little is known it is twisted and corrupted by those who claim to follow his teachings.
Jashin is viewed as the god of death and destruction, that couldn't be further from the truth, while that may end up being the outcome to the extreme, Jashin is actually a god of Chaos and Change.
Chaos is neither good nor evil, it is truly neutral, as in small amounts chaos can be a good thing, too much and it can be the cause for mass destruction.
Seeing how his image has been perverted and twisted to suit others needs Jashin decides it is time to take action, plucking a soul from the well of reincarnation and sending it into the world to give birth to his chosen one, one who will carry out his will in the world to spread chaos as he intended and with his true blessings
Jashin's blessings:-
Immortality
Enhanced regeneration
Enhanced chakra recovery
Future:-
OC Kills or converts Hidan
OC spreads comical Chaos throughout the elemental nations
