Known as the “Galactic Fairy,” she is a pop idol from Macross Galaxy fleet. She constantly tops music charts, and it is said that it is impossible not to hear her songs if you live in this galaxy. Naturally, her popularity is soaring high in Galaxy’s sister fleet, Frontier. Due to her beauty and singing talent, she is a very proud and self-assured person. Sheryl has recognized the singing talent of Ranka Lee and often offers to help her ‘behind the scenes’ to realize her dream of singing. Sheryl’s first encounter with Alto Saotome was when he served as a backup ‘performer’ at her first fleet concert. Eventually she also develops a crush on him.
Sheryl is apparently a failed experimental subject called Fairy 9 and was “discarded” by Grace O’Connor in Gallia 4, but she made it back to Frontier because she was in Michael’s VF-25. Grace O’Connor revealed to her recently that she used to be an anonymous and homeless orphan girl living in Galaxy’s slums in the past. Grace also revealed that she gave the name Sheryl Nome to her and that Sheryl is suffering from a terminal “V-Type” infection and will die soon.
In Sheryl ~Kiss in the Galaxy~ it is revealed that Sheryl is the daughter of Abel Coureaux and Sally Nome. Sheryl’s trademark earings were a gift from her mother who received them from her own mother, Mao Nome. Sheryl’s parents were killed by Galaxy because they opposed a project involving mandatory implants for all citizens. After their deaths, Sheryl is rescued from the streets by Grace O’Connor.
