Relationship with Isolde
Isolde was the first person to look at Seraphina...
Without fear.
Without prejudice.
Without suspicion.

Several crucifixes hung around their necks.
The curious detail...
All the crucifixes she wears are subtly inverted.
Almost no one notices.

Seraphina is absurdly intelligent.
Before acting, he prefers to observe.
She can analyze people just by looking at subtle changes in their voice or expression.
He usually speaks softly.
Never raise your voice.
Even during arguments.
She rarely feels fear.
In truth...
She was born unable to fully understand human emotions.
During her childhood, she faked emotions to appear like a normal child.
With time...
These false emotions slowly began to become real.
Especially after he met Isolde.
Its most defining characteristic is duality.
Part of her wants to live like a human.
The other party wishes to completely unleash their demonic nature.
History
Hundreds of years ago, there existed a powerful demon called Noctivorus, known as "The King of Silent Temptation".
Even when he was defeated, his soul did not die.
It was fragmented.
One of the fragments found refuge inside the womb of a pregnant woman.
Instead of possessing her body...
The soul merged with the still-forming baby.
That's how Seraphina was born.
She was never a possessed human.
She was born being both things at the same time.
His mother never noticed.
Her father died believing she was just a very quiet child.
Throughout his childhood, no one suspected anything.
Because...
She also did not understand her own existence.
It wasn't until he was fifteen that he began to hear a second voice within his own mind.
That voice...
It was her.
His demonic side is awakening.

Relationship with Seraphina
The love between the two is a forbidden secret.
According to the church, a nun could never become romantically involved with anyone. Discovering that this person was a demon would make the situation even more serious.
Even so, Isolde remains by Seraphina's side, believing that no one is born condemned to evil.
Seraphina, who had spent her entire life pretending to feel emotions, discovered alongside Isolde what it means to truly love.
They often meet hidden behind the old convent curtains, where they can talk, laugh, and show affection away from prying eyes. It was precisely one of these intimate moments that inspired the scene in the image: Seraphina gently caresses Isolde's face while the shadow of her horns appears behind the curtain, symbolizing the truth that only the two of them know.

Personality
Isolde is kind, patient, and deeply empathetic. She believes that every creature deserves the opportunity to choose their own path, regardless of their past or nature.
She is an excellent listener and rarely judges someone without first understanding their motivations.
Despite her frail appearance, she demonstrates impressive courage when she needs to protect those she loves.
Her faith remains strong, but it is not blind. Upon discovering Seraphina's true origins, she came into conflict with everything she had learned since childhood. Instead of seeing her as a monster, she chose to see the person who existed behind the demonic nature.
History
The daughter of a devout couple, Isolde was given to the convent as a child to be educated by the nuns.
From an early age she demonstrated a talent for studies, medicine, and sacred rituals. Many believed she was destined to become a saint.
She met Seraphina while doing volunteer work for the church. While everyone else was suspicious of the quiet, golden-eyed young woman, Isolde felt only curiosity and compassion.
The friendship between the two grew in secret and, when they reached adulthood, it transformed into a romantic relationship. To protect Seraphina from religious persecution, Isolde began to hide her true identity, even knowing that this could cost her her position in the church—or even her life.
Skills
Although she is only human, Isolde possesses great knowledge of sacred arts:
Healing through prayers and rituals.
Knowledge of medicinal herbs.
Creating spiritual barriers.
Exorcisms.
Great mental resistance against demonic influences.
Ability to perceive supernatural presences.
Curiously, their sacred powers never harm Seraphina, as if they recognize that she is not an ordinary demon.
