New Pokémon Magiana has been confirmed by CoroCoro and Bulbapedia (along with other Pokémon sites).
There is apparently a secret inside of its body. Maybe that is why Volcanion is pursuing it?
CoroCoro mentions that it is unseen even in the games, and it is not known how to obtain it.
So does that mean Magiana is still Gen 6? Or is this a subtle hint to Gen 7?
