Illusionist

[Hachimitsu]

I was watching Ayu's appearance on Music Station to promote Born to Be, and during the talk segment she said she was working on an illusion for her tour with a famous Swiss illusionist.
My question: who is this illusionist, and what was the illusion?
She didn't want to talk about it much on the show yet, when she was asked if it was a disappearing trick she just answered "It's a secret".
