Chapter 1 - Ninja in the New World

Naofumi Uchiha, current acting clan leader of the Uchiha Clan and Jonin of the Hidden Leaf Village, is thrust into a knew world against his will. With a new weapon in the form of a magical shield, and a lot of life experience to go off of, he will guide himself and his allies in the trying times to come, against a devilish princess, a horrible king, and a conspiracy involving a whole country.

Meh, not like he hasn't done similar stuff before on his missions.
