"The Risks of the Reanimation Jutsu" (穢土転生のリスク, Edo Tensei no Risuku) is episode 333 of the Naruto: Shippūden anime.
As the Kage continued their battle against Madara, they seemingly gain the upper hand in the battle, meanwhile elsewhere Chōza keeps a trappedDan in the loop about what exactly was happening on the battlefield. Upon hearing that the real Madara had been reincarnated as well, Dan exclaimed that the situation had taken a turn for the worst and urged his former comrades to focus all their energies into stopping the Impure World Reincarnation user, to which the Akimichi noted that the Allied Shinobi Forces was doing all they could. Upon seeing his brother, Sasuke tries to stop Itachi so that he may speak with him, but the elder Uchiha pressed for time opted to use his crow summons to evade his younger brother. Arriving at the cave where Kabuto was located, Itachi makes his intentions to stop the technique clear, though a haughty Kabuto informs him that it is a technique with nearly no risks to the user. The Kage's battle takes a turn for the worst when the ever-cynical Madara turns the tides against them after they make a mockery of him. Creating multiple wood clones, Madara sends five to each Kage to turn the five on one advantage against them. Pressing forward his advantage, he nonchalantly asks the Kage to decide whether or not the clones should each use Susanoo. Back at Kabuto's hideout, Sasuke who has pursued his brother thus far decides to fight alongside him, adamant to get the answers he sought from Itachi for so long much to Kabuto's amusement as he himself readied for battle.
