Castuera's father is from Mexico, and his ancestors originated from the Spanish city Castuera. Her mother is of Okinawan descent. According to an article published by the Smithsonian Asian Pacific American Center, she was "born at home in a commune to non-hippy parents."
Castuera graduated from the California College of the Arts, and it was at this university that she got involved with Giant Robot, a bi-monthly magazine of Asian and Asian American popular culture. After graduating, she moved to Los Angeles and eventually landed a job as a character designer on the Adult Swim series Metalocalypse after she drew a card for the series' lead character designer, Songgu Kwon. After an indie comic of hers was well received by Pendleton Ward, she was hired as a storyboard revisionist on the Cartoon Network series Adventure Time. She was eventually promoted to storyboard artist, and served in that position until she left in 2013 to focus fully on her art career. In October 2014, however, she returned to the series to temporarily storyboard several episodes during the show's seventh season, and during the show's eighth season, worked as a storyboard revisionist.
