Sherry is another member of Lyon's group alongside Yuka, she uses Marionette magic which is somewhat similar to Celestial Spirit Magic where the user has someone or something fight for her. Marionette magic however uses inanimate objects and turns them into animate creatures such as rocks creating a golem, or a tree making them into "Marionette dolls". This type of magic is a very advantageous magic to have when going against a Celestial user as the Marionette user can CONTROL the spirits.

Ref: (there was no good references sadly so, I would love to hear what you guys come up with, she is a kind of power crazed woman but also down to Earth, can get a bit insane sounding but also similar to Perona from One Piece)
