Naruto: But it doesn't make any sense. Why now? Why come back to the Leaf Village after all this time? Is it just to fulfill your stupid old mission? For what? According to you, your village doesn't exist anymore, so what's the point in destroying ours too? Or is it... Someone has given you a new mission to destroy the Leaf?
Gennou: Oh no, rest easy. I'm not here because anyone sent me here.
Naruto: Then why have you come?
Gennou: Well, you see, it just seemed like such a waste.
Naruto: A waste? What are you talking about?
Gennou: I've grown old. Each day I'm alive could be my last. I thought what a shame it would be for me to pass into darkness without anyone ever knowing what I've done.
