Who Are You?.Naruto enters Tailed Beast Mode and attacks Tobi with Kakashi and Guy looking on, the former initially hesitant to join the fray due to disbelief of the masked man's identity before Guy snaps him out of it. Tobi unleashes a shower of gigantic chakra receivers, paralyzing B and Gyūki. Naruto creates a shadow clone and it charges forward with Rasengan while the original prepares a Tailed Beast Ball with B and Gyūki acting as a shield. As Naruto launches his technique, Tobi simply phases through and with that, fully enters the other dimension. There, he witnesses the clone earlier and realizes that Kakashi did not just teleport the Rasengan but the clone itself. With little time to react, Tobi curses Kakashi before he is hit by Naruto's Rasengan; his mask shattered into pieces. Kakashi and Guy were both shock to find the masked man to be their former comrade Obito Uchiha, who was student Minato alongside Kakashi and Rin Nohara before the events at Kannabi Bridge where he was assumed to have died. As Guy informs Naruto of their opponent's true identity, Kakashi is devastated when Obito saw he no reason of revealing himself as Kakashi failed to protect Rin. Naruto motivates a devastated Kakashi that Obito needs to be stopped before intercepting his Fire Style: Bomb Blast Dance with Kurama's tails. Just then, Madara appears alongside Obito to the others' surprise.
