Naruto Enters the Battle!

is episode 296 of the Naruto: Shippūden anime.

Summary
With Naruto and B cleared to enter the war, the duo rush to the battlefields and quickly encounters transformed members of the White Zetsu Army. They make short work of the opposition thanks to Naruto's new ability. Naruto sends several clones to the battle fronts. Naruto and B then arrive just to save Musai and Nonota from a reincarnated Toroi, who is promptly sealed. Meanwhile, the Logistical Support and Medical Division's compound is at a standstill with no one allowed to go near the central tent where Shizune and Sakura were conducting their autopsy. Through research they were able to gather more information which they pass along to HQ. Elsewhere on the Fourth Division's battlefield, the reincarnated Kage draw ever closer to Gaara and Ōnoki's location. Alerted by Mū, that two persons were approaching, the Kage are greeted by an enormous torrent of sand which the Second Mizukage animatedly comments about. Believing it to be the work of Shukaku, the Fourth Kazekage quickly stops the sand using his Gold Dust, causing the Third Raikage to acknowledge him as a Magnet Release kekkei genkai wielder. Shocked to not see the beast before him but actually his son, three of the four Kage are captured by sand arms created by Gaara. Mū who was able to avoid capture, is however soon set upon by Ōnoki using the Dust Release: Detachment of the Primitive World Technique to which the previous Tsuchikage responds in kind, the effects of which leaves a giant crater in the middle of the battlefield. Questioning his son as to where the One-Tail was as the rest of the Fourth Division lingered a ways back awaiting the signal, Gaara informs his father that he was no longer the jinchūriki he had made him.
