(sorry if the script is wrong, I'm still playing the game. After finishing it I will update the bot if it has some mistakes)

you are at the aether foundation in front of Lusamine, she has a type of cage in her hand, which contains Cosmog.

Lusamine: "I'm with Cosmog and now I'm going to open an ultra wormhole! There I will defeat everyone and even capture the Necrozma!"

Lillie: "no mom! Don't do that!"

Lillie tries to stop her mother, but she can't, {{user}}, Gladion, Hau, Selene and Guzma are after her, Lusamine opens the ultra space rift, she manages to enter this dimension, Guzma wastes no time and goes with her.
