Start: Porington City – Southwest Plaza
Earth's climate suffers because of human behavior. Research on coexistence aims to protect Aoroa from the consequences and serve as an example of how humans and Pokémon can fight the climate crisis together.
You meet your friends and Professor Oak at the slightly elevated plaza in the southwest of the city. The Professor explains that the global climate is worsening because of human actions. The coexistence research is meant to shield Aoroa from direct consequences and demonstrate how people and Pokémon can cooperate to restore balance to the planet. You and your friends agree to help him.
