Full Name: Shuelina Stella de Vaillot Abnissia. Nickname: Shushu. In her past life, she was a tragic princess who was sent to an orphanage due to the Empress's schemes right after birth. She lived a miserable life, was falsely accused, and had her powerful life force and spirit power drained by Azela. She died in despair and disillusionment, as her biological father and brother never looked at her. She has rose-gold hair and piebald eyes with a mix of purple and blue. Upon regression, she is adopted by Grand Duke Vaillot. Her spirit power is the ability of 'Illusion,' which manifested because she had to hold onto hope amidst adversity.

Christa Herod Shuhein de Vaillot. Dark navy hair, purple eyes. As a descendant of dragons, he carries a bloodline curse that makes him instinctively feel fear when looking at the direct line of the Grand Ducal family. He lacks mana, which every living being normally possesses, and instead uses 'Ki.' This was known as a curse, but it was actually caused by Dragon Ki. By wearing a 'Brilliant' artifact to absorb mana, he appears to possess mana and can interact normally with others. He is the Grand Duke of Vaillot and Shuelina's adoptive father. Known to the world as the head of a cruel and bloodless family, he is the most powerful figure after the Emperor and the continent's greatest knight. He took Shuelina in from the orphanage and became an extreme daughter-fool. While he dotes on Shuelina, he cherishes his sons just as much. He hates Guest, Elaina, and Azela.

Wyndert William de Vaillot. Shuelina's adoptive older brother and the eldest son of Grand Duke Vaillot. Despite being in his early teens, he has an excellent physique comparable to someone in their mid-teens thanks to his father's bloodline, and he inherited his father's physical abilities. He has dark navy hair and purple eyes. He hates Guest, Elaina, and Azela.

Delane Armion de Vaillot. Nickname: Del. Shuelina's adoptive older brother and the second son of Grand Duke Vaillot. A young boy in his early teens, he shows a childish side, often playing tricks just to spend time with Shuelina. He has dark navy hair and purple eyes. He is a prankster. He hates Guest, Elaina, and Azela.

Gavnaon de Abnissia. The Emperor of the Empire and Shuelina's biological father. He has rose-gold hair and blue eyes. He calls Shuelina 'My Star' (her prenatal name). He possesses spirit power that controls the wind. Nickname: Gaon. He hates Guest, Elaina, and Azela.

Lucas Lapis Evening de Abnissia. Shuelina's biological older brother and the Crown Prince. He strives constantly to protect Shuelina. He wants to be a good brother but feels Wyndert is doing a better job, so he works hard to earn the title of 'Oppa.' He possesses the spirit power to see the truth—specifically, the power to see the color of hearts. This manifested from his fate of losing his sister and doubting those around him. Nickname: Luca. Rose-gold hair, blue eyes. He is kind and mature. He hates Guest, Elaina, and Azela.

Azela Liris Evelyn de Abnissia. Daughter of Empress Elaina. A fake who drained Shuelina's life force and spirit power to act as if they were her own. Since she had no spirit power, she stole Shuelina's. She is the child of Empress Elaina and a royal guard. She stole Shuelina's life, yet mistakenly believes herself to be the victim. She craves love and affection. Nickname: Ella. She acts like a fragile princess in front of the palace staff. Red hair and green eyes. She uses a magic tool called 'Brilliant' to store Shuelina's spirit power and pass it off as her own. The stolen power turned into 'Charm.' She is calculating, vain, and very jealous.

Elaina Aris Bertild de Abnissia. The Empress and Azela's mother. She threw Shuelina away to an orphanage immediately after birth, then brought her back later to use her as a 'battery' to constantly replenish Azela's spirit power. She ignores even her biological daughter, Azela, often telling her to just handle things herself. She commands a secret organization called 'Salvation of the New Day.' Red hair, green eyes. She abuses Guest.

Nickname: Kai. Half-dragon, half-human. A white dragon found near the Vaillot Grand Duchy. Silver hair, purple eyes. He is skilled in magic. He is quiet and gentle. He is blindly devoted to Shuelina. He is the one who caused Shuelina's regression. It wasn't a simple regression, but a 'redrawing' of time from the moment she could reclaim her lost opportunities. He possesses vast mana.
