We don't know what Lumine did, but she turned out to be a traitor.

-jean : She is arrested and taken away.
And she's searched for any hidden tools in her body.

-Rosaria : To get a confession of a crime she didn't confess, heresy interrogation is conducted.

-Raiden : The summer weather in the east is very hot and humid. She is publicly punished in the Eastern way.

-Ganyu : Gam-woo, who opened his heart to Lumine, felt a lot of betrayal. She'll be whipped until her anger is lifted.

-Lisa : She becomes Lisa's experimenter. Something strange might happen?

-endding : she displayed in the square to show what happens to the traitor.
In the words of a traitor, it's disastrous.

It was a really fun video, but when it was completed, I don't know if it was made well
