Nina

The protagonist of this work. An orphaned girl who lived in the city of Dayah under the Fortna Kingdom. Due to her rare azure-colored eyes, she hid her face with bangs and pretended to be a boy. She lost her parents to an epidemic five years ago and lived with the orphaned brothers Saji and Colin. After Colin's death from illness, she was deceived by Saji and sold to Azure, where she was asked to take the place of the deceased Princess Alisha. As Princess Alisha, she is 15 years old.

She has a cheerful and tomboyish personality. Being an orphan, she had no education, but in less than three months, she learned all the knowledge of a priestess and acquired the manners of a princess, though she is still studying hard. She bears no resemblance to Princess Alisha except for the eye color, but since her face is not well-known, the switch has not been noticed. Her original hair is short, so she hides it with long hair extensions.

About three months after taking the place of Alisha, while intensely studying the knowledge of a priestess and the etiquette and education of a princess, she begins to be drawn to Azure. To protect Fortna, where Azure resides, she sets off alone to Gargada with the cooperation of the Grand Emperor.
