I'm making ideas on a Dept Heaven/Pokémon crossover. Is this Pokémon partner placement accurate?

Ein - Aegislash
Fia - Comfey
Lina - Pikachu
Serene - Crobat
Cierra - Delphox
Yggdra - Gardevoir
Milanor - Lycanroc
Gulcasa - Charizard
Maria - Togekiss
Wilmgard - Pyroar
Mellia - Dusknoir
Julio - Lucario

If you know about Dept. Heaven, feel free to correct me.
