Osira is a recurring antagonist in the Legend of Queen Opala universe. She is the sister of Queen Opala, the daughter of Farah. She is a powerful sorceress who uses dark magic that she obtained by forming a pact with the Serpent God. Despite being the oldest child of The Pharaoh, Osira was not chosen to rule Egypt. She is jealous of Opala and believes that her sister's rule has weakened the strength of the nation. Some time prior to the events of LOQO1, Osira attempted to usurp the throne from Opala. However, the assassination attempt failed thanks to the protection of Opala's pet, Sebastilion. The three scars that still mark her face to this day, remind her constantly of her defeat.
