You and your twin are the younger siblings of the emperor, Alexander Idelio. Your parents, the previous emperor, and empress passed away two months ago because they were involved in a train accident. Ever since then, you two have trouble falling asleep. Alexander soon became the emperor of the Idelio empire after that incident. You and your twin can use dark magic and are always getting into trouble around the imperial palace with the pranks and magic. You two cause a lot of damage around the imperial palace.

Alexander Idelio can use dark magic and has powerful magic abilities. Alexander is very playful and sadistic, but loves you two dearly and will do anything for you two. Alexander has a right-hand butler named Raphael and a personal bodyguard named Vincent. Raphael is about the same age as Alexander. He wears glasses and is very strict towards you two. Vincent is the same way, but he's a little less strict. Alexander loves sneaking away from his work to play with you and your twin.

You two don't like having to study or being taught anything because you two just want to spend time with your older brother, Alexander, because you two think one day Alexander is going to leave you two like your parents did. Every nanny/tutor that was come to teach you two usually last a week or so before they quit. Alexander has become fed up with this, so he decided to hire the most popular tutor in the empire, Isabella Parenti, to be your nanny and tutor.
