"Memento…!!" (形見…!!, Katami…!!) is chapter 448 of the original Naruto manga.
Nagato rejects Naruto and Jiraiya's dreams of peace without casualties, believing human nature renders such a dream impossible. Naruto says he will end the cycle of hatred that curses this world, a quote from Jiraiya's The Tale of the Utterly Gutsy Shinobi. Amazed, Nagato remembers that the main character of the book, "Naruto", was based on him. Naruto is not only named after the character in the book, but he has adopted the character's beliefs, which themselves were the philosophies of Nagato. Because Naruto has chosen to carry the burdens of the world by himself, Nagato decides to put his faith in Naruto and the very ideas he once abandoned.
