I also have a theory on the Epitome of Envy incident concerning Elluka/Irina (or to make it easier Ma).

My theory is that Both of their souls swapped into Kayo's body due to it being a Body Swap, meaning that whatever was in the body got switched into the other indiscrimanantly. All of Kayo's soul and the demon got swapped into Lukana's and Ma took Kayo's body.

This is also why a man that lives in the exact same town that talks all about Kayo and her talent talked to her like she was a 'Stranger', the song states she is talked about by everyone, if the man lived in the town he would know about Kayo for her talent.

The other part is that Irina specializes in using the Vessels, she would be able to use Kayo and use the vessel, along with calling on the demon in the scissors.
