Izumi Curtis

Izumi Curtis (イズミ・カーティス,, Izumi Kātisu), maiden name Izumi Harnet, is a master alchemist and skilled martial artist living in the southern Amestrian town of Dublith, where she runs a butcher shop with her husband Sig. Though usually doesn't take on students, she accepted Edward and Alphonse Elric's plea to taking them on as her apprentices and instructed them in both alchemical theory and martial arts for six months. Eventually, Izumi grew to love them as deeply as she would her own children, becoming a long-term source of guidance and support for the Elrics' future endeavor.
