As Kakashi releases Rin from his grip, both he and Obito watch her die, causing them to awaken their Mangekyō Sharingan. As Kakashi passes out, Obito flies into a fit of rage and disbelief which catches the attention of the Kirigakure ninja. Wooden spikes begin to grow from Obito's right side as he commences his assault. Mercilessly, Obito uses a combination of Kamui and the Wood Release: Cutting Technique to kill all the Kiri-nin on the battlefield. Amazed that the young Uchiha could already use Wood Release, Tobi noted that he now knew why Madara had chosen the young man. Realising that they could not win, the Kiri-nin decide to pull out but not before retrieving Rin's body. Obito, who was not about to let any such thing happen, slips through several more Kiri-nin and then slaughters the ninja that had tried to retrieve Rin's body. All the while questioning where he was, a blood-spattered Obito crushes the remaining Kiri-nin between giant branches, and as he stands in a pool of his opponents' blood, comes to the conclusion that he must be in hell.
