The Rising of the Shield Ninja

Naruto always wanted to be a hero. He just never expected he would become one because of a book hitting him during the thief of the Forbidden scroll. Together with Iruka, both have to survive this new world where everything is ruled by numbers and odd rules. Yet, it seemed ninja exist in this world, and their mysterious master wants to assist them after they bolted from the summoning room. However, the road to return home was long and dangerous. Far dangerous than they ever could imagine.
