Deep within the bowels of Naruto's mind, a being long since asleep began to regain awareness of the events surrounding it. No one knew the being's gender, and throughout its existence, no one dared to ask. Seriously, what thinking person would actually ask a nigh omnipotent being its gender and so risk offending it? Hence, the legend of the bijuu being genderless was born out of the desire for preservation of one's culture.
As awareness shifted into consciousness, Kyuubi no Youko, the nine-tailed demon fox, began tossing around its considerable youki stores in hopes of finding a weakness in its jail. What it found instead surprised even it, considering it had lived long enough to see nearly everything.
An emotion so common to the bijuu flooded Naruto's mind completely: rage. Naruto possessed enough of this complex emotion that the bijuu felt sure it could find advantage somehow, yet every attempt was blocked by Naruto's own rage-fueled chakra. The exact opposite should have happened; rage-fueled youki should have melded seamlessly with the chakra, completely overloading the power output. It seemed the ancient beast had mistaken the circumstances. While Naruto's mind was practically saturated with rage, a part of it remained clear and lucid - acting as a command center does for a troop deployment.
Outside Naruto's mind, time once again began its proper course, but certain noticeable differences soon emerged. For one, the silence fled as Sakura screamed bloody murder and Sasuke hyperventilated. The current Central Command (CC) in Naruto's brain quickly blocked out these stimuli, deeming them unimportant to the task at hand. Second, Naruto moved faster, more efficiently and with more grace than he ever had before. It appeared that the chakra and cold rage saturating his system recognized the size of the threat and forced his body to match it.
He weaved and dodged expertly, years of running from angry jounin and chuunin aiding him. Step by step, he inched closer to the two chuunin nukenin from Kirigakure no Sato (Opposing Force - OPPFOR), progress slowed by the sidesteps, blocks and parries he needed simply to stay alive. Slowly, his pace quickened as he grew comfortable with the types of movements required. While he'd already been close to the OPPFOR, his short stature (which translated to shorter appendages and less reach) required him to be closer still. Thankfully by the time he'd reached the required distance, he noticed something of a pattern in the OPPFOR's movements. CC found itself analyzing the information and issuing new orders (in addition to the defensive motions). A strike to left OPPFOR's wrist. A bone-shaking blow to right OPPFOR's ribs. Over and over, the retaliatory strikes flew, some landing, but most missing. The process lasted until one by one they stopped attacking, as Naruto never seemed to run out of energy. He now stood poised over them, ready to drive the final blow home.
