is episode 61 of the original Naruto anime.

Synopsis
Iruka worries about Naruto since he is fighting Neji Hyūga. Outside of the battle arena, Kabuto kills an ANBU to use as a disguise.

Naruto's clones fail to hit Neji, and Neji aims for the real Naruto but is unsuccessful. Then the two more clones of Naruto attack Neji, only to fail when Neji uses Eight Trigrams Palms Heavenly Spin. Hiashi and Hinata are shocked to see it. Naruto makes seven clones, which encircle Neji and charge at him again, only to be repelled again.

Neji takes the Eight Trigrams Sixty-Four Palms stance, which surprises Hiashi, and strikes Naruto sixty-four times. Genma goes up a bit and says the match is over. Neji goes up to Naruto. Kiba then asks Hinata if she is okay. Neji was suddenly shocked to see that Naruto is trying to stand up. Naruto feels dizzy and remembers Lee and Hinata when they had critical injuries due to their matches. Neji is surprised to see Naruto quickly recover from the attack.

Naruto asks about the Hyūga clan and Neji's hatred for it. Neji takes off his forehead protector and reveals the Hyūga Main Family's Juinjutsu. Neji then explains about the cursed seal and says that his destiny was decided when Naruto was chosen as his opponent.
