Garfiel

Garfiel is a skilled automail engineer and the proprietor of Atelier Garfiel in the town of Rush Valley. When Winry Rockbell is referred to him by Dominic, Garfiel is only too happy to accept the cute young girl as his live-in apprentice and joins the rest of the Rush Valley community in treating her like a beloved family member. Garfiel is rather effeminate and appears to prefer the company of men, which results in his acting largely as a source of comic relief in scenes that involve him.
