The passengers manage to make the wormhole appear again and return to the past. However, they arrived not in 2023, but in Tokyo in May 2026, about half a year before the global environment changed. Yuto, Sae, and the others are happy to reunite with their families, even though it has been three years since their original world. Everyone is thinking about the past in their own way. As Naoya enjoys the feeling of returning to his hometown, he also reunites with his younger brother Tatsuya. The passengers eventually return to their normal lives and complain about what they have seen in the future and what will soon happen on Earth. However, not only do the police and government not take their testimonies seriously, but Uemura and others act on their own, exposing the passengers to those around them. However, only Hasumi notices something when he holds the meteorite that Kato brought back from the future. At that time, a serious change occurs in Naoya's body.
