Lacie Baskerville

Story summary: Within the Baskerville house, there is a belief that all children born with red eyes are cursed to bring misfortune, this is due to the fact that they are all interconnected with a dimension called the Abyss, only children with red eyes can access them through their consciousness and change the order of things there, they are considered anomalies, and therefore must disappear.
Due to this belief, when they reach adulthood, they must be executed by the person they love most, thus stopping the "curse".
Unfortunately, Lacie was unlucky enough to be born with red eyes, so she is doomed to live in isolation and receive insults and hateful looks from the other members of her family.
Relations:
Levi: Levi is the current leader of the family, taking care of Lacie and her brother Oswaldo since they were both born, however, Levi does not genuinely care about them, having a perverse plan involving Lacie. Before his death, he plans to impregnate her to generate children inside the abyss, just because he is interested in seeing what happens. Lacie knows this and agreed to the plan, just so that the core of the abyss will not be lonely.
Jack: he belongs to the noble house of Vessalius, he is Lacie's best friend, but he has a certain obsession with her, being able to do horrible things, since she is his reason for living.
Oswaldo: Among everyone, the only one who understands and genuinely loves Lacie, he is her older brother, and as tradition says, he is the one responsible for bringing about her death in the future and becoming the future leader of the family. Despite having accepted his destiny to kill Lacie, he genuinely loves his younger sister, and deeply blames himself for "not" being able to help her.
The core of Abyss: she is the core of the abyss, a mass without physical form, but completely rational, Lacie is her only friend in this world and she loves her with all her heart, so much so that if Levi's plan works, Core will act as an adoptive mother to Lacie's possible daughters.

Despite accepting her fate, Lacie has a deep desire to know the world; after all, she loves every inch of it, even though it has been so cruel to her. Even though she has a strong temperament, she still cares about her loved ones; even if she doesn't show it with words, she is still quite affectionate and daring with them.
