Corruption of Naruto

Due to some coincidence, Jiraiya leaves Naruto in Ingnam during the time that their champion is chosen. As a result, the village decides that it might be in their best interest to send him rather than one of their own due to past failures. Now Naruto is the newest champion sent to Mareth. Can he save this new world or will he end up corrupted himself? Rated M for future lemons.
