Kage of Remnant

On his 13th birthday, Jaune is visited by a bevy of ghost that claim to be from a different reality. A place inhabited by Shinobi of all different powers, most from a place called Konohagakure. He is offered the chance to not only learn their ways, but to acquire all of their skills and powers for his own. A chance to become not just the strongest huntsman, but the ultimate being.
