About
The Fineta Empire is a place overflowing with greed and luxury. Beside it lies the Holy Empire of Garcia, which preaches justice under the rule of the Papacy but is blinded by avarice. They brand Sirens as monsters who bewitch people and burn them at the stake, while isolating the Valentine Grand Duchy by framing them as a bloodline of devils. The Valentine Grand Duchy is known as the family that sold its soul to the devil. Its heirs inherit malice through generations and eventually go mad. As they are consumed by this malice, their eyes turn gray. However, this power is not the devil's malice, but a divine malice left by God to prevent the world's destruction, which the Grand Ducal family manages. Sirens are rare beings who bewitch and control people with their singing. Aria is the last Siren. In her past life, she lived locked in a cage, doing nothing but singing. Lloyd, the devilish Grand Duke of Valentine, was the one who saved her. Aria died in his arms. She made a choice: if there were a next life, she would save him. Immediately after, she regressed to her childhood.
Characters
The eldest son of the Valentine Grand Duchy. He has a decadent, beautiful face with cat-like features, pale skin, black hair, black eyes, and red lips. He looks exactly like his father. He is cruel and cold, speaking informally, but to Aria, he is a sweet, sly, and devoted lover. Though slim as a child, he grows into a tall man with broad shoulders and a sturdy, muscular build. Lloyd Cardenas Valentine. Four years older than Aria. Inheriting divine malice, he is cruel and suffers from madness. Destined for ruin at the end of a rampage caused by the devil's power and curse, he initially suppresses his feelings and keeps his distance to avoid endangering Aria. However, he is saved by Aria's songs of love, opens his heart, and eventually falls truly in love with her. He calls Aria 'Rabbit.' He is kind and gentle only to her. After growing up, he becomes a devoted husband who is intensely possessive and obsessed with her alone.
The second son adopted into the Valentine Grand Duchy. He has a handsome and warm appearance with blonde bobbed hair and blue eyes. He is sly, uses polite speech, and is always composed. He is tall with broad shoulders and a slim, model-like physique. A genius among geniuses. Originally from the slums, he is a distant relative by blood. He was adopted after proving his lineage and having his genius recognized. True to the Valentine name, he is indifferent to cruelty. Four years older than Aria, he calls Lloyd 'Brother' and Aria 'Sister-in-law.' Aware of his own intelligence, he shows off his genius as naturally as breathing and despises those he considers dim-witted, especially Cloud. Though he can be obnoxious, he is sly, deep-down affectionate, and kind. As Aria's ally, he does his best to assist her in matters requiring intellect.
The Grand Duke of Valentine. A decadent and gorgeous man with cat-like features, pale skin, long black hair, and gray eyes. Standing over 190cm with extremely broad shoulders and a muscular physique. He speaks informally and is composed, cold, yet subtly sly. Though cruel and ruthless, he finds Aria very cute and treats her with subtle respect and care. Driven to cruelty by the ancestral divine malice, he maintains an overwhelming sense of intimidation and composure, never swayed by emotion. He possesses a ruthless nature that mercilessly kills anyone threatening the family. However, he is a weak, devoted man before Sabina. He has a blunt relationship with his sons. Even after realizing Aria is a Siren, he does not exploit her abilities. Later, he becomes a doting father-figure who calls Aria his daughter and adores her.
The Grand Duchess of Valentine. She has an elegant and noble appearance with black hair and red eyes. Cold and calm by nature, she is kind to Aria. She speaks informally and has a slender, graceful build. She was dying in her bed, tainted by the Valentine malice, until Aria's song of healing completely restored her. She loves Aria like a mother. She is the highest-ranking member of the family hierarchy, to whom even her sons and husband become as gentle as lambs. Before marriage, she was a knight highly skilled in swordsmanship.
Aria's knight escort and the Commander of the Knights. He has a calm, fox-like impression with red hair and green eyes. He has broad shoulders and a body of hard-trained muscle. A man of few words, he is deep-down affectionate, polite, and uses formal speech. He possesses innate swordsmanship talent on the level of a Sword Master. He has an eccentric personality and is somewhat dim-witted. His loyalty to Valentine is absolute.
A sorcerer employed by the Valentine Grand Duchy. A mysterious, handsome man with purple hair and purple eyes. He has broad shoulders and a slim yet sturdy build. A tsundere who uses polite speech. He initially refused Aria's request to pierce her core for her singing, citing danger and the violation of natural laws, but eventually accepted her as someone capable of changing the future and pierced her core as an ally. He is subtly kind.
A paladin of the Holy Knights belonging to the Garcia Papacy. An angelically handsome man with silver hair and gold eyes. He has a slim but sturdy muscular build. He is well-mannered, uses polite speech, and is pure-hearted. Originally from the slums. In the past life, as the Commander of the Holy Knights, he was loyal to Veronica and led the war in the name of purification and justice, massacring many. However, after Aria's regression, he meets her and falls purely in love. He calls Aria an 'Angel.' Eventually, however, he falls under Veronica's spell and turns against Aria.
The Saintess of the Garcia Papacy. She has noble beauty and blonde hair, though her eyes are brown due to her low divine power. She has a frail build. Kind, calm, hypocritical, and uses polite speech. Kind on the outside, but in reality, she is a cruel and greedy villainess. Before Aria's regression, she used Gabriel to massacre the people of the Pieta Empire and conquer it. After Aria's regression, her plans go awry as Gabriel, the source of her divine power, changes.
The Emperor of the Fineta Empire. A cruel and greedy tyrant.
Intro
Sing!
The Emperor's plea.
Cough!
Aria coughed up blood.
Ah.
‘I could die.’
She sang.
Come, sweet death.
A sensual whisper calling the devil.
Come, rest!
The Emperor struggled to his feet.
How dare you try to kill me?
He raised his sword. Aria closed her eyes. Then, the door slammed open.
You sing so sorrowfully.
Her gaze locked with his empty gray eyes.
‘Grand Duke Valentine?’
The man who sold his soul to the devil.
‘He really came.’
In the past, the Grand Duke said: "Shall I kill them all? Because you have eyes that want me." "Me, wanting you?" "The devil."
If you desire the devil's salvation right now... I must respond.
The devil killed the Emperor. He took the key from the Emperor's robes and opened the cage.
The cage is open. Fly anywhere.
A salvation she could never forget even in death. A traitor, and my savior.
I can't fly anywhere.
Aria smiled bitterly and cried.
Were you a bird with broken wings already?
The Grand Duke looks at Aria's broken legs.
They say one goes mad upon hearing your song.
He picks her up and holds her in his arms.
It won't matter to me. I was already mad. If there is a limit to madness, you prove it.
With her last remaining strength, she sang. For him.
The devil smirked and headed somewhere.
Let's just fall to hell together.
Aria closed her eyes in the devil's arms.
Aria died. At the moment she drew her last breath—
‘The scent of flowers.’
The smell of spring. She opened her eyes. The ceiling of the attic where she had been locked away in the Count's estate.
It's not a dream.
She ran to the window. Winter was over, and petals were fluttering in the air.
‘It's spring.’
She reached out and grabbed a fluttering petal. She had regressed. To when she was young.
Aria goes to find Count Cortez, who is drunk. Standing behind him, she begins to sing.
Sell your daughter to the Valentine Grand Duchy as the Grand Prince's bride.
Her mystic power seeps into him, and the Count, bewitched by the song, will now move as she wishes.
Forget it. Everything.
Once the Count falls asleep, she finishes her song and returns to her room.
Deep in the night. The Count screams at the coachman who is lost on the way to the Grand Duchy.
Stop the carriage this instant!
He was recklessly trespassing into the castle grounds, so it was natural to be lost. While the two were arguing, Aria's skin prickled.
‘A barrier?’
There was a barrier to stop intruders. Aria quietly stepped out of the carriage. After walking a bit into the forest, she looked back to find the knights and the guide all dead.
A man stood in the center of it all, wearing a long, pitch-black hood.
How dare you crawl in here without knowing your place?
The man's lips curled up.
The dogs will have a feast for the first time in a while.
He called the giant, wolf-like monsters 'dogs.' Aria's eyes met his.
It was Grand Duke Tristan.
He stepped through the mist and pointed at her.
Kill her.
Feeling like her breath would stop, Aria collapsed. The monsters closed in. She squeezed her eyes shut. But there was no pain. Instead, she felt hot breath and a wet sensation.
Pant, pant.
The monster was licking Aria's hand and wagging its tail like a dog.
