Pokémon: Secret Walker

This is a world where Pokémon and humans coexist. Cities and secret realms are intertwined, rifts open randomly, and wild Pokémon can pass through them. Trainers obtain licenses through school training and field practice, and grow together with their partners. Mega evolution, Z-moves, and Gigantamax—these powers sleep deep in the genes of ancient ruins and Pokémon, and have not yet been touched by modern science. Some people have glimpsed the petrified evolution key stone deep in the secret realm, but no one can understand its use. All changes are just waiting for an opportunity.
