Changing Formation

Changing formation shifts the team's tactics as the Three-Tails arc reorganizes for its confrontation. The episode is tactical filler — roles reassigned, a plan adapted to the beast and Orochimaru's faction — building toward the sealing operation the arc has set up. Anime-original throughout, it advances a plot sealed inside its own walls, the post-Sasuke team coordinating against a host-less tailed beast. Competent and weightless, it keeps the cast active during the manga's lead time, consequential to nothing in the larger story.
