Story
"This resolve alone, I will surrender to no one."
She was once the beloved daughter of a wealthy man.
But her days filled with light
were swallowed by darkness through an orchestrated tragedy.
Having lost everything,
she returns to her homeland burning with ambition.
There, she meets
heretical young men
who carry the power of witches.
Bonds woven by wounded souls.
Warmth kindled in a frozen heart.
Hope called love,
known only to the lonely.
—But how will it end...
Death is merely a turning point.
Hope is the prelude to despair.
This is a story
of saving fates on the verge of being lost.
Character Introductions
Heroine
The Fate Weaver (Weaver)
Yolca Yulewood (name changeable)
Title: Vy-xen / Living Bait
A girl who was buried as one of the dead. Beneath her frail body lies a will as sharp as a blade, and she makes her way through the world shielded by the looks she inherited from her mother.
She admires her philanthropist parents and longs to use wealth for others' sake just as they did. She works tirelessly to reclaim her place in House Yulewood, though few believe in her bloodline.
Having no real power of her own, she always carries a knife, a stun gun, and other means of self-defense — so well-stocked that her companions jokingly call her an arms dealer.
A thoroughgoing realist who openly declares that "you can't hold onto your ideals without getting your hands dirty," she also carries the contradiction of being moved to pain by other people's tears.
Main Characters
The Trickster of Masochistic Aesthetics (Altruist)
Tilkett Halmshaw
CV: Nobuhiko Okamoto
Title: Vy-xen / Physician
A cheerful, easygoing young doctor with a friendly smile — and a former delinquent. Even now that he's turned his life around, traces of his old rough speech still slip through.
He wields a "Gift" that lets him manipulate his own blood, carrying the dual nature of attack and healing. Using his power requires self-inflicted wounds, and he shows no hesitation toward the pain — he even harbors a dangerous ecstasy in the act of saving others.
He grew up in an orphanage that the heroine's parents once supported, and knew of her from a distance. The admiration he felt for her back then hasn't faded, and he still falls easily for her forced smiles and crocodile tears.
The Sacrifice of Order and Sin (Tribute)
Kanoa Fortis
CV: Kohei Amasaki
Title: Vy-xen / Gravekeeper
A "Grimnal" hailed as the strongest of his kind. His "Gift" allows him to control wind, letting him even turn his own body into wind.
He has used this power to hunt down many other Grimnals, but to ordinary citizens he too is simply an object of fear, and he's required to wear a restraint device on his finger whenever he goes out.
Sharp-tongued and perpetually cynical, he's extremely bad at expressing his true feelings. He often clashes with the heroine, calling her "ugly," but he does respect her belief in "fighting with the cards you're dealt."
The Innocent Desire for Submission (Submissive)
Heath Crescent
CV: Hikaru Midorikawa
Title: Vy-xen / Housekeeper
A housekeeper of overwhelming beauty. He oversees all household duties at Vy-xen and keeps a busy schedule serving several wealthy patrons as well.
He accepts his own beauty as an unshakable truth, and can even carry off a maid's uniform offered to him in jest. He always wears a hard, cold expression and harbors an intense hatred of human greed and corruption.
His "Gift" is nullification — it reduces any Grimnal's attack to nothing. Yet his icy, fortress-like composure quietly melts, for some reason, whenever he's with the heroine. He devotes a pure sense of devotion he has shown no one else to her alone.
The Dreamer of the Final Curtain (Amorist)
Eugene
CV: Takuya Sato
Title: Vy-xen / Trader
A sociable, deeply accepting trader who lives freely and stays true to his own desires. His warmth and deep empathy bring energy and harmony to Vy-xen.
He pours affection out to everyone without distinction, though poison lurks beneath it. He only ever says that he has lost his "Gift," and reveals nothing further about it to anyone.
He shows no interest in the heroine's mission or filial devotion, taking a morbid interest only in the moment she breaks down and falls apart. He toys with her using sweet whispers and mischievous fingertips.
The Violator of Destiny (Illegal)
Orsem Helhand
CV: Tomoaki Maeno
Title: Vy-xen / Lawyer
A lawyer who walks in the shadow of the law. Skilled in negotiation and scheming, capable and merciless. He always wears a calm smile and speaks politely to everyone.
Yet that demeanor masks an arrogant, overbearing attitude — even high-ranking officials shrink before him.
His "Gift" is foresight, though his low compatibility with it means the power is rarely put to use. He contributes to Vy-xen not through power borrowed from a witch, but through his intellect and violence.
He maintains surface-level courtesy toward the heroine, but no mercy lies behind it. At times, he even directs fierce, harmful intent toward her.
