Kakashi und Guy haben Tobis Maske zerstört. Jetzt müssen sie sich damit auseinandersetzen, wer er wirklich ist.
Naruto enters Tailed Beast Mode and attacks Tobi, causing both Kakashi and Guy to look on, stunned but Tobi later emerges from the blast, unharmed. Meanwhile, a hesitant Kakashi is in disbelief of the masked man's identity but Guy snaps him out of it. As the battle rages on, Kakashi is finally motivated to fight and prepares to join the fray. 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. Watching on, Kakashi and Guy are shocked to see that the masked man is their former comrade, Obito Uchiha who as a child had dreams of becoming the Hokage but who would never beat Kakashi or Guy. During his time at the Academy, Obito was later placed into a team consisting of himself, Kakashi and a young girl named Rin Nohara with the team being led by Naruto's father, Minato Namikaze. Obito had romantic feelings for Rin who actually loved Kakashi which in turn fueled Obito's desire to defeat Kakashi. However, Obito was left badly injured following a mission in which a boulder crushed the right side of his body. Believing himself to be on the verge of death, Obito gave Kakashi the Sharigan from Obito's own left eye which served as a replacement for Kakashi's left eye which had been left permanently scarred and damaged during a fight against a lone rogue ninja. When more ninja assaulted the cave, Kakashi and Rin were able to escape with Obito being engulfed by the landslide. In the present, rendered speechless, Kakashi is shocked that Obito survived.

仮面の男の能力は“すり抜ける”ではなく、体の一部が時空間へと移動し、あたかもすり抜けるように見せていた。その時空間はカカシの“神威（かむい）”の時空間と繋がっていることに気づく。
