As Sasuke has finally fulfilled his goal in killing Itachi and avenging his clan, he collapses from exhaustion. Naruto and his comrades find themselves held up by Tobi, whose strange jutsu is more than just a simple genjutsu. The Hidden Leaf ninja continue to fight Tobi, but all of their attacks manage to phase right through him. Neither can figure out Tobi's real powers or motive. Zetsu arrives to inform Tobi of the outcome of the match between Sasuke and Itachi, and Tobi drops his goofy persona in order to leave the fight and collect the brother's bodies. Before they're about to leave Kakashi notices Tobi's Sharingan eye, and wonders who he is.
As soon as they leave, Naruto and the others hurry and race towards Sasuke's location. Zetsu then arrives to inform Kisame about the battles outcome and also tell Sasuke's comrades that he's being held at the Akatsuki hideout if they wish to follow. Sasuke wakes up in a cave and Tobi approaches him, introducing himself. Tobi tries to befriend Sasuke by removing his mask and revealing his Sharingan eye and his identity. However, Itachi's Mangekyo Sharingan in Sasuke automatically turns on and Amaterasu is unleashed from Sasuke's eye, but Tobi evades it and mentions how in-depth Itachi's plans were. Tobi later explained that Itachi had implanted Amaterasu in Sasukes eye to detonate upon seeing his Sharingan. Sasuke asks what he means, and Tobi tells him that Itachi was trying to protect him.
