Karyl is a beast-race member in the game with long, black hair with a white streak in her bangs and green eyes. Her hair extends down to her ankles and is tied into two loose, low twin tails. At the ends of her hair the loop into ringlet-like curls. She has cat ears coming out the top of her head.
She wears a detailed blue and purple outfit with detached sleeves and adorned with magenta jewels and gold hemming. Her skirt has two layers of ruffles (one black and one white). She has thigh high stockings and a garter-belt on her left thigh that clips to her stocking. She has short, differing shades of brown boots. She also has a black cat tail with a white tip
When under Kaiser's control, Karyl's outfit changes to black and maroon colors instead and has fishnet stockings. There are minor changes to her outfit such as a fur hemming and a choker with a large, magenta jewel. She also sometimes wears a mask that completely covers her eyes.
