Unfortunately Naruto lost his cats ears in front of two guard cats; taking advantage of it Sasuke and Sakura entered the fortress but they left Naruto behind. Sasuke and Sakura split in two teams to find Nekomata faster. After some time, Sasuke was able to find Nekomata before his team-mates. Sasuke told him to agree to give him a print of his paw, however Nekomata used his genjutsu on Sasuke. He was able to cancel it with his Sharingan. After that, Nekomata and Sasuke started to fight with taijutsu, just when Nekomata was about to crush Sasuke with his paw, Sasuke is saved by Naruto and Sakura who managed to find Sasuke. Sasuke revealed that he didn't need to be saved and he activated exploding tags on the roof that fell on Nekomata. Once Nekomata fainted, Team 7 printed his paw and took it back to Nekobaa. In the end, Itachi was revealed to have defeated Nekomata in the past, and had asked it to fight Sasuke one day with all its might.
