By making progress on the game but if i told you you wouldn't have any fun :3
The thing is you don't get, you battle it but you will never get it. And you don't get the nine tail in naruto Ultimate ninja 3 was during the 1st season before the shippuden, and naruto doesn't get past 1 tails during that time. Therefore, there is no possible way you can play tailed Naruto. The only thing you can get close is when you do the ultimate, and get the awakening after it.
