Marie Shaderan
Voiced by: Rena Motomura
The heroine, who lived a very Cinderella life. Having spent her life being called ugly and stupid, Marie is frustratingly unable to understand that Anastasia was never whom Kyros wished to marry; even when he states to her face that he got their names wrong because of her poor wording. She is meek around others and tries to conform to what she thinks is appropriate, which only makes things worse for her; everyone at Kyros’s estate cannot figure out what she likes in order to help her adjust better. However, as she spends more time free of her parents’ abuse, Marie begins to discover how much she enjoys being free to choose.
In truth, she has been running her family’s estate due to her father being too much of an imbecile. All the abuse she suffered was to keep Marie from ever desiring to leave after seeing just how bad a shape her home was in.

Kyros Granado
Voiced by: Daiki Hamano
The duke whom fell in love with Marie. He was born to his father’s foreign mistress Liu-Liu, while the official duchess never bore a child; with the untimely demise of his father, along with Kyros’s own accomplishments on the battlefield, he became the next duke without any backlash. He’s loathed noble women who only ever wanted to marry him for status, which is why he was so drawn to Marie; she didn’t care about status and had a caring heart. Even though he repeatedly explains to Marie that he got their names mixed up, Kyros is left utterly frustrated with her being unable to accept that she is NOT a replacement for her sister. This comedically leads to him showering her in unnecessary gifts and learning Marie has no clue as to how to choose what she likes on her own.
Kyros ultimately decides to bring the abuse Marie has suffered to the public eye, believing it will also help save her homeland from her father’s incompetence.

Anastasia Shaderan
Voiced by: Minami Tanaka
Marie’s younger sister. She was close to Marie as a child, but her parents forced them apart in order begin conditioning Marie into being their slave; while pampering Anastasia to make her ignore what was going on. Anastasia noticed the horrible things, but because she took Marie’s face value word that she was fine, she tried to ignore it for years. Once the engagement to Kyros arrived, Anastasia could tell from the dress sent as a gift that he had gotten her and Marie’s names mixed up. She used the carriage ride to run away and hide out as a boy, getting a job as an apprentice professional sewer.

Head maid of Kyros’s household. She is polite and very no-nonsense, but looks after Marie with kindness; seeing she has such poor self-esteem that she has to constant direct her into not overreacting. Within the early days of her serving Marie, Mio fires two maids sent by to be the ladies-in-waiting; they had be exacerbating Marie’s confidence issues in a long term plot to become Kyros’s mistresses. This not only angered Mio, but made Kyros so upset her gave them a death glare.

Liu-Liu
Voiced by: Sayaka Ohara
Kyros’s mother and the mistress of his late father. While she is fluent in both her native and the local language, she has trouble writing and reading the latter. Liu-Liu very much likes Marie and makes the effort along with Kyros and Mio to help her get past her unnecessary self-doubts. When Marie explained she did most of the talking and paperwork for her father, Liu-Liu realized that the entire reason that her parents didn’t want her to go was because they couldn’t do the work themselves.
Liu-Liu can often be found in the library, where she bonds with Marie over their love of literature.
