Naruto and co are impressed that Kakashi has declared the match over. Zabuza taunts him, declaring that Kakashi won’t be able to capture him so easily. He then appears behind Kakashi and kicks him backwards. Kakashi disappears into the river as Zabuza chases him with his big-ass sword (think Cloud in FF7). He sees makibishi (throwing nails) in the dirt and dives in the river. Kakashi emerges, trapped in Water Prison no Jutsu, as the tide has turned in Zabuza's favor. He then clones himself and goes after the three young ninjas. He strikes Naruto and knocks the headband off his head.
