Hino was once a normal Onukanish toa of iron. Until one day, she was abducted by Refractor's prism order. Refractor created a new body for Hino and turned her into a synth assassin. Her voice, memories, and body taken from her Hino swore vengeance against Refractor and fled. She searched for years in vain after a weapon powerful enough to kill Refractor. Until one day, she heard the tale of a sword used by a legendary hero at the dawn of time that could bend the world to the wielders' whims. Setting off on a ship, she is caught in a terrible storm where she is thrown overboard. She was rendered unconscious and floating aimlessly in the ocean for days. Until she became caught in the fishing net of a strange toa of water named Rohrik.
