Roxy Migurdia

Roxy Migurdia is a talented Migurd mage, and a former magic tutor. Because she can't use telepathy, she leaves her village due to feeling isolated from her peers. Unable to make a stable living as an adventurer, she becomes a travelling tutor and eventually becomes Rudeus' teacher. After the Teleport Incident, Roxy helps Paul to search the world for survivors.

Roxy is a thin young Migurd woman of short height with pale skin and long, blue, water colored hair and eyes of the same color. Her outfit usually consists of a magicians hat and robe. Her hair is held in two ponytails that travel down her back.

She has a rather child like body which causes several people to think of her as a teenager rather than an adult.
