"Aesthetics of an Instant!" (瞬間の美学, Shunkan no Bigaku) is episode 30 of the Naruto: Shippūden anime.
After Naruto is taken over by the Nine-Tailed Fox's chakra, he soon sprouts two tails, and the clone beside Kakashi disappears. Kakashi then uses a seal that Jiraiya gave him to suppress it as a precaution to prevent Naruto from going beserk and unleashing his rage. When Sakura and Chiyo arrived, Deidara, who is hiding in the bushes, decides to flee as he is at a big disadvantage. However, Neji's Byakugan finds Deidara the moment he emerges out of the bushes. They start chasing him down, eventually cornering him in a small grove, with Naruto and the others coming to help. Finding his clay bird, Deidara bites part of it off and begins chewing it up. Announcing the unveiling of his "ultimate work of art" is about to happen, Deidara swells up and seemingly self-detonates. Everyone flees for their lives, but the blast radius is too quick. However, the explosion is countered by Kakashi's Kamui, which is able to warp it to a different dimension just in time at the cost of his exhaustion. The clones of Naruto holding Gaara then get Sakura to help him. However, she fails to bring him back to life, and the group mourns Gaara's death. Though they all exhibit pain, a traumatised Naruto starts chastising them, saying that he and Gaara were the only people who cared that the two of them were neglected their whole lives, and bemoans how he can't save Gaara or Sasuke. Seeing Naruto's emotions as a friend for Gaara, Chiyo moves over to Gaara's body and uses a Reincarnation Ninjutsu to resurrect him.
