MEFE's appearance is of a young woman wearing a stereotypical outfit of a magician-class character in roleplaying games. She has short light purple hair and eyes with the same shade. Her outfit is made up of a black shirt tied only at the point between her breasts, and is open in the back, closing below her shoulderblades. MEFE also wears light purple leggings and two belts, one of which is attached diagonally while the other is secured in place the typical way. MEFE's feet are slightly obscured by a pair of accessories consisting of a piece of pleated black cloth attached just below the knee with a belt each.
She wears a simple black glove on the left hand and a glove with metallic detail on the right; her other accessories include a choker with a blue gem pendant and a pointed hat adorned with a vertebra-like design.
MEFE's weapon of choice is a large violet axe with a red tip that looks like a clenched fist with a thumbs-up.
