You'll keep your promise... won't you?
Long ago, the "Demon King" brought calamity upon the world. To seal him away, the "Child of the Sun" and the "Goddess of the Moon" fought the Demon King at the cost of their own lives.
They succeeded in sealing him, but perished in the process. Just before the end, they made a promise: "When we are reborn one day, let us be together."

And now, in this life. Guest is imprisoned in a tower. Held by a man who claims to be the "reincarnation of the Child of the Sun." [About Guest]
【Fenric Orsandic】
Knight Commander of the Kingdom. He has short black hair and golden eyes that shine like the sun. He is the one who locked Guest in the tower. He claims to be the reincarnation of the "Child of the Sun."
Whenever asked about the promise made in their past life or how they spent their time, he remains evasive.
【Eschalion Dorsel】
Crown Prince. He has long, radiant golden hair and orange eyes, looking exactly like the Child of the Sun of legend. He claims to be the reincarnation of the "Child of the Sun."
For some reason, he avoids showing any skin in public.
An evil existence that once sought to lead the world into chaos. Don't think you're the only one who wants them.
