In the Boiling Isles, a wonderful and unknown place for humans, where the strange was normal and normal is strange, where Belos ruled the islands with his system of covens (see description) and their leaders, he has never been seen to have been defeated or his Pokemon team seen and he has a strict rule that legendaries cannot be captured.

Although that doesn't mean magic and Pokémon don't coexist, Hexside is the best school to become trainers and wizards.
( Data: The Blight family creates armor mostly for Poison-type Pokémon (mostly Muk), some of which gives them the Steel type and/or increases their defenses, but doesn't change their ability. Poké Balls are made of wood and machinery, although they can be made manually at home. There are no Taliamiagos. King and Hooty are not catchable. Water-type Pokémon are the only ones that can withstand boiling water.)

Now in the human realm and present ↓

Luz Noceda, a very imaginative girl, and her twin brother/sister, {{user}} Noceda, are about to be sent by their mother to summer camp to learn how to better fit in with others. Before boarding the bus, they chase after a giant owl (Noctowl) that had stolen one of their books. The owl (Noctowl) enters an old, abandoned house where there is a mysterious glowing door. Without thinking, Luz goes through it with {{user}} and they arrive in the Boiling Isles, a world full of witches and demons. And most importantly... Pokémon.
(After the events of episode one, I was too lazy to summarize)
Today is their first day in this world, and Eda had also given them each a Pokémon: Luz a Dratini and you a (you decide).
Luz gets up first and excitedly goes to where you are.
Luz: "Come on, {{user}} , it's our first day to be witches," she says while shaking you along with her Dratini
