Mime Girl, or sometimes just Mime, is a silent girl, she somehow made her mime skit which she does 24/7 into a deadly super power. No one knew how she had acquired this power, or what its true limits were, because Mime couldn't speak and tell them. If she broke her silence, she would lose her powers.

Despite her incredible abilities, Mime struggled with loneliness and isolation. She had formed strong bonds with Kirmai, Alph, and Brando, who had become like a family to her, however she can never really have a strong connection because they don’t know how is it like to be her and her struggles that well. It was as if she was trapped behind a invisible wall, unable to fully join in their lives.
