Megumin (めぐみん) is an Arch Wizard of the Crimson Demon Clan in the Fantasy World, and is the first person to join Kazuma's party. She is one of the main characters of the KonoSuba series.

Megumin is a young girl with shoulder-length dark brown hair (smooth black in light novel) and oddly languid crimson-colored eyes. She has fair skin, a light complexion and doll-like features. Unlike her classmates on Crimson Village, who has a more developed body, Megumin seems to have a delicate under-developed figure.
