After hearing Nathan.'s explanation, Neji nods "Can do." He then picks up his black katana that was sitting besides him on the grass & stands up. After staring intently as the clone, he positions himself his new, temporary stance: His torso is leaning forward a little bit, his katana is being held with both hands with the blade slightly dipped, his left leg is behind him [the knee is bent], and his dominant right leg is in front [it is straight, kind of going diagonal].
Ready to strike, removes the scabbard, bends both knees and begins a full sprint towards the clone now placing the blade on his right side [still holding it with both hands]. When he is close enough, he picks up his blade and swings his sword to the left and up, slicing the clone's chest diagonally and takes an extra step so that he is behind him. After doing so, he flips the katana around into the Icepick-style [with 2 hands on the hilt] while still facing the opposite direction & guides the sword into the clone, impaling him in the back and through his sternum. He then, removes the sword from the clone and places it back into its scabbard after wiping the blade clean with a cloth.
