The New Three-Way Deadlock

is episode 374 of the Naruto: Shippūden anime.

Summary
To solve the main problems of the battle that Sai mentioned earlier: the need to get past the Ten-Tails' defence and heal the wounded on the front lines — Naruto, Sasuke and Sakura summon Gamakichi, Aoda, and Katsuyu as solutions respectively. Hiruzen remarks how the new trio remind him of the previous three-way deadlock. Naruto remarks his summoning's growth in body and attitude before the latter jumps high into the air over the beasts' guards and fends off attacks while Sakura uses her summoning to heal the wounded shinobi as an observing Shizune silently praises the former's power. Meanwhile, Sasuke easily slips and cuts through all guards and defence with the aid of his summoning and Susanoo. Once he has a clear view of the Ten-Tails, he aims his Amaterasu bow and arrow at the same time Naruto readies his giant Rasenshuriken from above. Naruto recalls to the time of his Rasenshuriken training during which he stated to Yamato that he and Sasuke are compatible not because his wind beats the latter's lightning, but because his wind can power up the former's fire. As a result of the wind powering the flames, a spiralling mass of black flames is created and hits the beast as a slightly tearful Sakura and their classmates cheer them on.

Trivia

 * A small inconsistency occur in the episode. In "An Unnecessary Addition", Jiraiya stated he nearly faced death twice and stated both times. Yet, in the filler flashback within this episode proved otherwise as Orochimaru nearly slain an injured Jiraiya.
