Wanderer

Wanderer opens a filler arc as the team encounters a mysterious traveler tied to a forbidden jutsu, a self-contained story slotted after the Itachi arc's weight. The episode sets up its anime-original premise — a wanderer, a dangerous technique, a guest cast with their own stakes — within the sealed frame. It gives the cast a standalone thread while the manga advances offscreen. Competent filler setup, it builds toward a self-contained conflict, every consequence held inside the arc and irrelevant to the canon timeline.
