"Ultimate Defence: Zero Blind Spot!" (死角ゼロ!もうひとつの絶対防御, Shikaku Zero! Mō Hitotsu no Zettai Bōgyo) is episode 61 of the original Naruto anime.
Iruka worries about Naruto since he is fighting Neji Hyūga. Outside of the battle arena, Kabuto kills an Anbu in order to impersonate him as a disguise. Naruto's clones fails to hit Neji, and Neji aims for what he believes is the real Naruto, but is unsuccessful. Then Naruto uses more clones of himself to attack Neji, only to fail when Neji uses the Eight Trigrams Palms Revolving Heaven. Hiashi and Hinata are shocked to see it, since it is a move taught only to the main branch of the Hyūga clan. Naruto makes seven more clones, which encircle Neji, and charges at him again, only to be repelled once more by Neji's revolving technique. Neji then takes the Eight Trigrams Sixty-Four Palms stance, which surprises Hiashi (since this technique is an elite move exclusive only to the strongest of the Hyūga main branch) and proceeds to strike all of Naruto sixty-four chakra points. Genma then walks up to the two to determine whether the match is over or not. Kiba then asks Hinata if she is okay, since Hinata is coughing up blood. Neji is surprised that Naruto is still conscious following the attack. Naruto feels dizzy but remembers when Lee and Hinata had critical injuries due to their matches, but still managed to stand up and continue giving it their all. Naruto manages to get back on his feet, shocking Neji. Naruto then 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 the circumstances surrounding his father's death and the Hyūga clan's branch family and says that Naruto's fate in their match was already decided when Naruto was chosen as his opponent.
