Iruka Umino

“[About Naruto] Well that's typical. Not happy unless he's giving people a heart attack.”

“[when Naruto transforms into a woman in front of the whole class] CUT THE STUPID TRICKS! THIS IS YOUR LAST WARNING!!”

“I hate the fox, but the boy - I don't hate the boy.”

“[as a child] Why should I be sad?! My parents died protecting the village from the monster fox. They're heroes, and I'm the son of those heroes! If I cry, it's because I'm happy! I'm not even sad that they went and left me all alone...”

“So I acted like an idiot. It was tough, has it been lonely for you Naruto, was it tough Naruto??”

“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.”

“It seems like the small leaves in the Village of Konoha have inherited that "will of fire" you spoke of, Third. The fire on the leaves will eventually burn greater and stronger... It will flash its light and protect this village.”
