The queen who despises all beings on the Blood Throne, the demon girl who seduces the world on the head of the giant dragon, the first female head of the imperial medical family, and the girl next door who was childhood sweetheart but could not step into the alien world. Stepping out of a small corner of the year, it becomes the most dazzling sun in the world. No matter whether the light it emits is golden or red, people can feel its light and heat even if they raise their heads or not.
