"*Introducing himself to Kakashi, Naruto …" — Sasuke Uchiha Quote

"When a person dies, he disappears, along with his past, current lifestyle, and his future. Many people die in missions and wars. They die easily and in surprisingly simple ways. Hayate was one of them. Those who die have goals and dreams. But everyone has something as important as those. Parents, siblings, friends, lovers... people who are important to you. They trust and help each other. The bond between the people important to you ever since birth and the string that binds them becomes thicker and stronger as time goes by... It's beyond reason. Those bound to you by that string will do that because it is important."

— Iruka Umino · Naruto

"Nine-Tails, you are merely a momentary life, a temporary existence of coalesced energy... energy that once was a single, ultimate form! An unstable force, lacking in intelligence or sapience, you require a guide to show you purpose. That guide is the Uchiha! The tailed beasts are but slaves to those with blessed eyes. Obey!"

— Madara Uchiha · Naruto

"People are stupid. If I don't do this, there will be no peace. Eventually, time will pass and the pain will heal. Eventually, checkmate's power will weaken and people will begin fighting again. This time, they will use the weapon themselves and once more know true pain. And for the short time, peace will come again. It will give birth to short period of peace within this endless chain of hatred. That's my wish."

— Pain · Naruto

"I will become a bigger badass than my father. And a stronger shinobi than my mother!"

— Naruto Uzumaki · Naruto

"Mm, she's strong and scary. I bet she's single."

— Kabuto Yakushi · Naruto

"The true measure of a shinobi is not how he lives, but how he dies."

— Jiraiya · Naruto
