Obito and Kakashi faced off. Obito attacked first, rushing toward Kakashi at incredible speed and throwing a punch at his face. Kakashi leaned left and slapped Obito's right hand aside with his left. As the momentum carried Obito slightly off balance, Kakashi drove his right fist toward his chin.
Obito reacted instantly, pressing down on Kakashi's fist with his left hand. At the same time, he planted a foot on Kakashi's bent thigh and flipped forward over his head, drawing a kunai in midair and slashing at Kakashi's throat.
The instant Obito passed overhead, Kakashi knew he would never waste such a perfect opening and was already prepared. His expression did not change when the kunai suddenly appeared before him. He smoothly whipped a kunai from his ninja tool pouch and raised it, blocking Obito's slash. Sparks flew as the two blades collided.
They traded taijutsu blows, neither able to gain the upper hand. Both were panting by the time their fists collided in another heavy exchange. Kakashi used the impact to spring backward, forming hand seals as he retreated. "Lightning Release: Chidori!"
Kakashi landed on both feet and braced one hand against the ground, the Chidori in his right hand roaring continuously. He quickly arrested his backward momentum, then pushed off with both feet and charged toward the still-retreating Obito. As Kakashi's Chidori drew closer, Obito knew it was too late to defend. He could only activate Kamui and make his body intangible.
But Kakashi seemed to have anticipated this. He activated Kamui as well and thrust his Chidori into the black hole. Seeing Kakashi use Kamui, Obito knew his own technique could no longer stop him. With no other choice, he twisted aside and released a barrier, forming hand seals. "Fire Release: Great Fireball Technique!"
