Ginko was born on the planet Riel into the royal family. As princess she saw it as her duty to protect her people when Rriel was invaded by the sirusians. When Sensei saves her they team up to try and stop the dragon from rampaging through the Sirusian homeworld. Her sense of empathy led her to sense a young boy floating outside the ruined Sirusian planet, they take him to Earth after the dragon is defeated and look after him like an adoptive family.
