Shinobi by Trade, Mage by Design

Life's never easy when it comes to being Uzumaki Naruto. Destiny? Fate? Such concepts were nothing but a crock. Instead of achieving his goals and becoming Hokage after ending the 4th Shinobi World War, he winds up being subsumed into the sky by a celestial phenomenon never before seen in the Elemental Nations. To adapt to this new world, it'll take more than just guts. AU. Harem.
