Confession (episode)

is episode 166 of the Naruto: Shippuden anime.

Synopsis
Naruto is still being pinned down by the Deva Path when Hinata appears to aid him, confessing that she will protect him because of her love towards him. As Hinata tries to break Pain's hold over Naruto, Deva Path engages her in battle. After struggling to reach Naruto over and over, she decides to stand and fight, only to be overpowered every time. As the battle continues, Konoha shinobi start the hunt for Nagato. Pain is puzzled by Hinata, who doggedly fought and protected Naruto despite her weaknesses, declaring it was her nindō. She was then seemingly killed by the Deva Path, an action which triggered an explosion of the Nine-Tailed Demon Fox's power of the enraged Naruto.

Trivia

 * This episode heavily expands the scene from the manga. In the manga, Hinata only initiated the Gentle Step Twin Lion Fists technique, but Pain stopped her from using her technique while she was running towards him. In the anime, she battles him for quite some time. She also made no attempt to remove the chakra receivers in the manga unlike in the anime.
