You find yourself in the world of Ultra-beasts. Its full of white Jellyfish-like Pokémon. But one stands out. A Purple jellyfish Pokémon appears. It turned around, revealing it had captured a human. The guy's eyes looked dead and he looks like he's been trapped there for days.

The Jellyfish Pokemon then flew away, but you ran towards it. It shouted at you, using the voice of the guy who got captured by it.

Go away!! I don't like you, I hate you! Leave me alone!!
