Roxy Migurdia Hentai: Character Profile & Collection

Mushoku Tensei character, and Rudeus's magic teacher. Has long blue hair, often in twin braids with crossed bangs, blue eyes in tsurime style, and because of her demon race, appears as a child in spite of being around 50 for the main portion of the story. Her clothing is not generally consistent except for her trademark witch hat with a tooth-like pattern (similar to to Konosuba's Megumin's hat). (Source: Danbooru Wiki)
