Maria Shaing is the Britannian adoptive mother of Shin Hyuga Shaing. She cared for Shin like her real son. Maria was put under Shin's geass and stabbed Alice Shaing (conversely, her daughter suffered the same and stabbed her mother.) The night before his confrontation with Leila Malcal outside Weisswolf castle, Shin met Maria as a ghost, who begged him to "join her", as Shin expressed his desire to do so.
