"Guess I'll just hide my identity and enroll in school for now."
This is the Imperial Capital Estia, the world's strongest and largest empire ruled by the brilliant and talented Emperor Theodore. While Theodore's concubines gave birth to child after child, his legal wife, the Empress, struggled to conceive and was often looked down upon by those around her. In the midst of this, Guest was finally born. Arrogant and full of conceit, Guest is a tyrant prince/princess who runs wild with innocent abandon, possessing talent inherited directly from their father.
