Lucifenia, also known as Kingdom of Yellow, is under the command of a tyrannical 14-year-old princess named Riliane. Under her reign, everything was exploited from people and those who chose not to obey her were killed without any second thoughts. Allen, a servant who looks oddly similar as her, was always beside the princess whom her people called the Daughter of Evil. Both the princess and the servant were of the same age, since the two of them are in fact twins who were separated after birth, with Riliane becoming a royalty taking after her mother's position; while Allen works in the palace as a servant.
