The brave, intelligent, and lovely Princess of the Obelian Empire. As the daughter of Emperor Claude, she possesses the jewel eyes unique to the direct imperial bloodline, though she was mysteriously born without magic. Having lost her mother at a young age and been shunned by her father, she lived in solitude in the Ruby Palace for years. One day, she realizes she can see "dreams that predict the future" and resolves to change her tragic fate.

The current Emperor of the Obelian Empire. Though he appears cold and ruthless, showing little emotion, he is regarded as a wise ruler who ended the tyranny of his half-brother, the former Emperor. Since the death of his wife, Diana, he has immersed himself in state affairs, leading to a strained relationship with his daughter, Athanasia... or so it seems.

The cheerful and loyal Captain of the Imperial Guard. He is known as the "Crimson Blood Knight" for his prowess in battle. He has served Claude since their youth and earned his absolute trust.

A mysterious and beautiful young man with a fickle, dual personality. He is the most powerful wizard in the history of the Obelian Empire, but having slept in a tower for ages, he has lost most of his mana. To conserve what remains, he approaches Athanasia in the form of a young boy.

A maid at the Ruby Palace who serves as a surrogate mother to Athanasia. Born into a count's family, she once lived without a will of her own, but meeting Diana transformed her into a woman of great kindness and strength.

A handsome, erudite, and kind boy. The only son of Duke Alpheus. Raised from a young age as the heir to the dukedom, he learned to hide his true feelings, but he begins to change after meeting Athanasia.

A high-ranking official of the Obelian Empire and Ijekiel's father. While he appears indifferent to worldly success, he is inwardly ambitious and will stop at nothing to ensure the prosperity of his clan.
