Naruto… I’m going back to where our teacher waits for me. To watch how your story ends. I think you’re the third part of this trilogy… The first was Jiraiya and he was a masterpiece. But I, I was garbage, I was a bomb, an utter failure. My way was wrong, even our master wouldn’t acknowledge me as a true part of the series. The third and final part is here. Wrap it all up! Be so stellar that everyone forgets how terrible the second part was, Naruto!
