We've been told to expect the unexpected for the final stretch of Naruto, but so far it looks a lot like the masked Tobi is the series' main villain. He's certainly been the architect of its major conflicts and tragedies. But who's actually under that mask? Series author Masashi Kishimoto says that we will not have to wait much longer to find out.
In a five question Q&A in this year's 35th issue of the Japanese Shonen Jump, Kishimoto answered:
Question: What is the connection between Tobi and Madara?
Kishimoto-sensei: Both ninja know one another. What kind of relationship do they have? Well, that will be gradually revealed as the story progresses!!
Question: Will Tobi’s identity be revealed in the future…!?
Kishimoto-sensei: Yes, it will. In fact, Tobi’s identity should be revealed within the next couple of weeks so until then please continue with your predictions!!
Kishimoto also let fans knows that Naruto and Sasuke will be meeting again in the Fourth Shinobi World War.
