She is Edward Elric and Alphonse Elric’s close childhood friend of ever since their young life in Resembool and is almost like a sister to the two and essentially their only family. An amateur surgeon and mechanical repair specialist/enthusiast, Winry is Edward's rear line support as his personal automail engineer and mechanic, making sure his prosthetic right arm and left leg are always in good working order. Additionally, she provides a great deal of emotional support for the pair and plays the role of Edward's love interest.
