Awakening

When Mizuki tells Naruto about the Kyuubi, he finally snaps and wanted nothing with this village, the betrayal of his Jiji not telling him, the beatings given by the villagers and shinobis, the mistreatment all because he was the jailer. When Iruka was knocked out due to the loss of blood, Naruto accidently kills Mizuki and runs away with the scroll of seals, whilst awakenening a leveling system. Making a new friend whilst traveling through the elemental nations and then to a different universe.

This is similar to an RPG game, but I don't own Naruto and other anime that I include here.
