When Naruto awakens, he comes into contact with his father (the future Fourth Hokage, Minato Namikaze).

One trailer has shown that during this period, Minato was on a team with Shibi Aburame and Chōza Akimichi, seeking to intervene in the conflicts enveloping Roland, with its princess Sarah in the middle of the crisis. A young Kakashi Hatake is tagging along with them.The same trailer also shows Minato charging up a Rasengan - curiously, its color is green rather than blue, as Naruto's.

In the trailer, Naruto is seen wielding a chakra infused kunai and fighting unknown mechanical figures. Minato is also seen interfering in the fight, aiding Naruto. He asks Naruto if he is a Konoha shinobi.

In the other trailer, Naruto and Minato combine their Rasengans against a giant puppet.
