Fiore's Sage, Brother of Prophecy

Naruto, after being told hes to be banished after bringing Sasuke back to the village, finds a seal in his apartment that Kushina used when she first arrived. As he activates it unknowingly, he is summoned to the mountains of the Land of Iron, where the seal explodes, sending him flying through the air, across the ocean. Thanks to an old man and Kurama, he survives.
