Hikari to Yami no Espressivo
Sofia Rosenberg serves as the game's main antagonist.

Due to the busy nature of her parents' work, they had little time to dote on their daughter. A corrupt maid, who would often harass Sofia and shame her for telling on her claiming that the little girl's words were lies, stained Sofia's reputation among the servants of the Rosenberg mansion. Because of the circumstances, Sofia had little to no interaction with the people at the mansion and grew up lonely.

Some time before turning 12, Sofia attends the first prince of Efenia's birthday party and meets the second prince and one of the game's capture targets, Alforth Efenia, and falls in love with him at first sight. Her father the Marquis Grave Rosenberg notices this and decides for the two to enter into a political marriage that also happens to follow the desires of his daughter. Unbeknownst to him, Prince Alforth meets the game's protagonist, Alicia Lindbell, on the night of the party, which serves as the first interaction of the player and the prince.

In all routes of the game, the prince falls in love with the protagonist instead of Sofia, who is driven to insanity upon noticing it. Yearning for the prince's attention and affection once again, Sofia harrasses her love rival until the prince finally notices this and takes it the wrong way. As punishment, he sentences Sofia along with her butler, Cyril, for his complacency, to death.

Early life
Sofia is born to Marquis Grave Rosenberg and his wife the Marchioness. Due to the busy nature of her parents' work, she seldom interacts with them. A maid would harass the young lady and accuse her of telling lies whenever Sofia tells on the maid and the maid explains her side. This caused other servants to avoid interacting with her, making her feel lonely and socially isolated. Those feeling feel especially amplified on her birthdays, for good reason.

On her sixth birthday, however, an apprentice butler named Cyril introduced himself as her exclusive butler and friend. Cyril promised to protect her and stay by her side forever as her friend. Sofia received a crimson rose wrapped in a lace cloth from Cyril as her birthday gift and thanked him for making her genuinely happy after all her years of loneliness.

One day, Sofia was tripped by the maid who would often harrasses her in her earlier years. Her face was bruised and she became dirty with dirt and foliage, especially on her hair. Crying, she ran over to Cyril to tell on the maid. Cyril comforts her and the maid immediately explains that Sofia only tripped and was embarrassed, making the girl pin the blame on her. Having had enough of the maid's lies, Cyril accuses the maid of betrayal against their master and calls over the guards to have the maid arrested and taken in as a lifetime criminal slave for suspicion of embezzlement and ruining the young lady's reputation by telling lies. Overjoyed, Sofia jumped into Cyril's arms for believing in her.

From then on, Sofia had Cyril to stay by her side. Cyril became her teacher in many subjects: etiquette, grace, housewifery, music, dancing. By the time she reached 10 years old, Sofia was already a refined lady to the point that she could pull off being a debutante without shame. Cyril also taught her the dark side of nobility, negotiations, self-defense techniques, and magic. Sofia put in major effort in learning all the things Cyril threw at her, no matter how complex they were for her age.

As expected of her as nobility, Sofia would often attend tea parties. She had learned to speak to others with flattery and nobles from other houses would send matchmaking requests to her, invitations that Sofia had all turned down.

A fine young lady
Six years have passed since she had met Cyril, and, with her and her butler's best efforts, Sofia had become a fine young lady, mannerly and beautiful, inside and out.

One night while preparing for bed, Sofia had Cyril brush her hair for her. She took a brief gaze at his face before getting noticed by him, who assured her that his face was not that interesting. Cyril diverted the conversation by reminding Sofia of her upcoming twelfth birthday. Upon hearing from Cyril that her parents sent only congratulatory gifts and messages, Sofia figured that they were most probably preoccupied with work, as usual. Although, she immediately recovered from the thought after hearing Cyril's confirmation that he and all the servants will be celebrating it with her. In reply, Sofia emphasized that what matters most was that he will be there with her, flattering Cyril.
