The ultimate battle fans have been waiting for is finally here as Naruto and Sasuke duke it out in "Naruto Shippuden" episode 475, which is said to be the finale of the anime series.

Titled "The Final Valley," the episode was teased with a promo that shows Sasuke declare his plans to destroy the tailed beast inside of Naruto and the other tailed beasts.

Having heard Sasuke's evil plan, Naruto proceeds to confront him, and thus begins the final battle that fans will reportedly ever get to watch in "Naruto Shippuden."

Fans who read the manga knows that Naruto and Sasuke's epic battle heralded the larger-than-life ending of the long-running story by Masashi Kishimoto.

With the strength of Naruto and Sasuke, it is going to be a long battle. The two are expected to fight to death in "Naruto Shippuden" episode 475.

It is unclear if the battle will begin and also end in the same episode. Studio Pierrot is known for protracting story arcs especially big ones.

A confrontation between Naruto and Sasuke is definitely a massive storyline. The strength of the two fighters will make for a really long combat.

Some fans might want to see it all unfold while others believe that seeing them brawl is enough. It remains to be seen what approach the studio will take in "Naruto Shippuden" episode 475.

What fans can count on is that the two strong warriors, who helped each other (along with Sakura and the others) defeat Princess Kaguya, will begin the much-awaited scuffle in the said episode.

There's no official announcement yet if it will mark the end of the most watch anime series in all of Japan. Some fans fear that it won't be and that the final segment of the anime will be marred with fillers.

This is something that Studio Pierrot is likely to do as viewers would know. This might not be the case after all, at least if the promo is anything to go by.

This suggests that the studio might actually give what fans have been dying to see in "Naruto Shippuden" since the beginning.

"Naruto Shippuden" episode 475 will air tomorrow, Sept. 8 on TV Tokyo.
