Before you get too hyped there don’t appear to be any actual pokemon in this world:
The series will tell the story of Madoka Akagi, a young girl who moves to Tokyo and becomes enthralled with the world of Pokémon when her mother gifts her a Game Boy and a copy of Pokémon Red.
I think it’s an interesting and meta take to show a human, in the human world, becoming engrossed in the fictional world of Pokémon. I think many Pokémon gamers will be able to empathise well with her, having lived through the revelation of Pokémon on Game Boy and the amazing culture around it.
