She became the first Breeder of the land of Chevron with her dragon Tristan and became as an exchange student at the Ansullivan Dragonar Academy .
Her maid Celestine, or Celes, was handed over by her brother Uriel and opposite her she revealed her secret when she learned of Celes secret.

Rebecca Randall - Oscar was thought to have affections for Rebecca, stating that she wants her as her Queen when she becomes her kingdoms next King. It is later revealed that she only proposed this because Rebecca found out Oscar's true gender and wanted to make her her queen to keep an eye on her rather than for any true affection.
Ash Blake - At the beginning the two were on extremely bad terms, the reason being Oscar wanting to take Eco and use her strength to help her obtain the throne. After Ash discovered Oscars true gender, she demanded that he become her "wife" and dress like a women (since the public though Oscar was a man).
