The story of God Wars Future Past likely involves complex themes related to gods and their interactions in a future and past context. It might include battles between different divine forces, with the past and future timelines intertwined. Maybe there are prophecies, heroic characters, and moral dilemmas within the narrative.
The older characters such as Kakashi would be cautious. They would recognize Naruto but also be worried about the implications of someone from the future being in the present. They would want to know if his presence could change the future in a negative way. For example, they might fear that his actions could lead to the earlier awakening of a powerful enemy. As for the villains, they might see future Naruto as a threat and try to eliminate him as soon as possible. Orochimaru, for instance, would be very interested in Naruto's future powers and might try to capture him to study. And the new generation of ninja in the past would look up to future Naruto, seeing him as a symbol of what they could become.
There was no past in the present, and no future in Bian Luohuan. This was because Bian Luohuan had traveled back in time to three years ago in the plot, exchanged his existence with Qi, created the present, and disappeared from the world. Yue Jin Chao had woken up three years ago and had no memories. This setting was based on the original game, the Legend of the Sword and Fairy 6. It was designed to save the world. The story of Bian Luohuan and Yue Qi was a karmic cycle. Their existence and choices were to deal with the Ming Lord. However, this information did not provide a specific explanation as to why Yue Jin did not have a past and Bian Luohuan did not have a future.
