Synopsis: Sapphire (voiced by Saya) is the princess of a kingdom that no longer exists. Having lost everything in her homeland of Silverland to the calamity known as “Nergal,” she wanders in despair until she finally arrives in Goldland.

Though burdened by her past, she begins to find a glimmer of hope as she encounters the kindness of the people there. But as if to sneer at her peaceful new life, the calamity Nergal appears once more. The very despair that once reduced her homeland to ashes now threatens to steal the light from this land as well.

Brushing away her tears of sorrow, Sapphire takes up her sword. This is the story of a lone hero who ties her ribbon and resolves to defy her fate.
