Touka is a member of the Fairy Tail Guild.

Touka is a slim and petite woman of average height. The ends of her hair are sausage curled, bundled into four thick strands in the back and two thick strands in the front. She dons a corset over a layered dress, as well as dark colored stockings. Touka has many ribbons on her person, including two in her hair and one around the frilled neckline of her dress containing a stone in the middle. She also wears a headband with a decorative rose design and a small jewel. Her guild mark is on the back of her right hand. Touka also appears to have a striped tail, which she hides under her dress.
