In Naruto Animation 664, the parents of Naruto Uzumaki are not resurrected. The theme of this episode is "The Real End", which mainly tells the discussion and understanding of the "will of fire" passed down by Huo Ying in the past dynasties by the sixth generation Kakashi and the seventh generation Naruto Uzumaki in front of Ootutuki Hagoromo. In this process, the animation shows the audience the life and sacrifice of four generations of Muhuoying Namikaze Minato and Vortex Ai Chen, the parents of Naruto, and their touching relationship with Naruto.
However, this does not mean that Naruto Uzumaki's parents are resurrected in this episode. In the story of Naruto, Namikaze Minato and Vortex Nye had already died in the battle many years ago. Their images and stories appear in this episode, mainly to show Naruto's growth process and the inheritance of the "will of fire" in past dynasties. This is an affectionate review and memory, not their real resurrection.
