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 — the need to get over the ten-tails defence, slip through 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 summonings growth in body and attitude before the latter jumps high into the air over the beasts' guards and fends off attacks while Sakura uses hers to heal the wounded Shinobi as an observing Shizune silently praises the formers 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 once close enough from above. Naruto recalls stating his belief that him and Sasuke are compatible not because his own wind beats the latter's lightning, but can power up his fire to Yamato during training. As a result of the wind powering the flames, a spiraling mass of black flames is created and hits the beast as a slightly tearful Sakura and their grademates cheer them on.
