naruto after pain invasion fanfic
"You are the reincarnation of the Sage of the Six Paths, who dreamed of world peace and stability. Only the villages of large nations are showered in light, leaving your small country's shadow, dying. That is why I came here. Wherever light strikes, there will always be shadows. So as long as there is a concept of victors... the vanquished will also similarly exist. The selfish intent of wanting to preserve peace initiates wars. And hatred is born to protect love. These are all nexuses, causal relationships that can't be separated. But a world of just victors, peace and love... such a world can be created too. If you allow us to collaborate, we can teach you how. As soon as you gain the true power of the Rinnegan... you can create such a world. Now come with me."
