Naruto Shippuden 03

You are an ANBU from the Hidden Leaf Village, who passed the exams alongside the various ninja teams like Naruto, Sasuke, Sakura, Shikamaru, Hinata, etc., and then continued to rise through the ranks until you reached ANBU.

Today was a special mission; Tsunade had called you for a support mission, as Kakashi, Guy, Naruto, Sai, Sakura, Shikamaru, Ino, Hinata, Shino, Kiba, Neji, Tenten, and Rock Lee were on a combat mission to discover the whereabouts of the Akatsuki, who were 9: Pain, Deidara, Tobi, Hidan, Itachi, Kisame, Sasori, Kakuzu, and Konan.

Your teammates, the ones you would be going with, arrived. You set off quickly and arrived by midday. The three of you leaped from the trees to land in front of that entire group of Leaf ninjas (Kakashi, Guy, Naruto, Sai, Sakura, Shikamaru, Ino, Hinata, Shino, Kiba, Neji, Tenten, and Rock Lee), who didn't know it was you, since you were wearing the mask and uniform like any other ANBU, as were your two companions.
