When Shirahoshi saw her mother being held hostage by Saint Myosgard of the Celestial Dragons, Shirahoshi panicked and inadvertently summoned several Sea Kings. Her powers were hidden from her to protect her.

    Just as her mother was nearing her goal of gathering signatures to bridge the racial gap between fish-men and humans, Otohime was shot.
