Father and Son, the Broken Crest

Dragging himself upright after a hard hit, Naruto dares his rival to switch on the Sharingan, certain that even the fabled eyes cannot break the resolve he calls his ninja way. A rush of clones charges in and is scattered almost at once, and Sasuke replies with a burst of flame. That present exchange serves as a doorway into a long look back at the years that shaped the two of them.

In the flashback, Itachi's place inside the family starts to crumble once his kin read his conduct as a betrayal, which nudges Fugaku toward paying closer attention to his younger son. Hoping to earn Sasuke a proper foothold in the clan, the father drills him in the Great Fireball Technique, and the boy locks it down through relentless repetition. Fugaku warns him against walking Itachi's path, since the fallen prodigy has lost the clan's trust, and that rare praise only sharpens Sasuke's hunger to surpass his brother.

Struggling with his shuriken work, Sasuke asks Itachi for help, but the older brother begs off and pokes his forehead on the way out, a small gesture that reassures Sasuke he has not changed too much. Curious about the doujutsu, Sasuke learns from his father about the Mangekyo Sharingan, a rare awakening only two Uchiha have ever reached, triggered under very narrow conditions. Back in the present, Sasuke corners the hiding Naruto, mocks his innocence, and drives a punishing blow into his ribs that sends him plunging into the water below.

An animation slip opens the episode: Naruto first stands beside the valley statues with Sasuke facing him, yet once the Sharingan flares and the shot cuts, the pair have swapped positions and Sasuke's hair looks noticeably different. The installment adapts chapters 223 and 224, sits within the Sasuke Recovery Mission arc, and first aired in Japan on April 13, 2005, with the English broadcast following on January 12, 2008.
