As the title says... I'm taking a day off. Or two.
I'll also explain some things—areas readers have been most confused about in the comments. They were actually all explained in the chapters... The currently known world settings are as follows.
① Main world: the timeline Fang Yuan was in (where the novel's main story took place).
② Future Parallel Timeline: the timeline where the Mewtwo Game was held.
③ The destroyed Pokémon World: the predecessor of the Secret Realm. More than 99.999% of the Pokémon and Secret Realms in Earth's timeline came from here. Humanity in this world went extinct in the medieval era, so there were no humans left—only Pokémon.
④ A certain normal Pokémon World: Pokémon created by humans, such as Mewtwo and Porygon, all came from here. [This was not the world from the previous book.]
By this point, many readers had noticed that this book's world setting continued the story of the previous book. Team Rainbow Rocket, the final boss of the previous book, traveled through various timelines and used different timelines for temporal fusion experiments. Worlds ③ and ④ were both experimental worlds affected by those fusion experiments. Timeline ③ was completely destroyed and merged into Earth through the power of Legendary Pokémon. Timeline ④ was only slightly affected, and a very small number of Pokémon accidentally crossed over. Mewtwo came this way. Since it was not seriously affected, that world remained largely intact. That was roughly it... These details had all been explained through scattered plot points in the story.
So later on, to serve the main plot, there should also be a storyline set in Pokémon World ④—the world where Mewtwo was born. Some original characters will appear, such as Doduo, Steven Stone, Cynthia, and Sakaki. Afterward, if Fang Yuan wanted battles
