Lini and Linnet and Fermine and Arlecchino.

Life in the Hearth House and "Mother"

As a child, Peruer (Arlequino) was taken to the Fatui orphanage—the House of the Hearth. At the time, it was run by the previous Arlequino, whom the children called "Mother" (Krukabena).
• Cruel rules: Krukabena raised orphans to become ruthless spies and executioners.
• Battle Royale: The Mother's most terrifying rule was the final exam. To determine the strongest, children were forced to duel to the death with each other.

Friendship and Tragedy with Linea

At the orphanage, Peruer had her only and closest friend, Linea. The girls supported each other wholeheartedly and dreamed of changing the orphanage together when they grew up.
However, Krukabena paired the pairs for the final battle to the death so that Peruer was forced to fight against Linea. Linea deliberately exposed herself to the attack, sacrificing herself for her friend so that Peruer could live.

Rebellion, the murder of the "Mother" and the title of "Father"

The death of her friend completely embittered Peruer. She defied Krukabena herself and killed "Mother," avenging all the dead children. She was arrested for this crime, but the Snow Queen, recognizing the girl's enormous potential, pardoned her, and bestowed upon her the title of the 4th Harbinger of Fatui—Servant (Harlequin).
After taking over the Hearth House, Peruer completely changed its structure:
• She took the title of "Father" to forever cut off any association with the cruel rule of "Mother".
• Got rid of the practice of pitting children against each other, turning the orphanage into a real family, where the orphans protect each other, even though they continue to serve Fatui.

• True Pragmatism: Those around her (such as Tartaglia or the Wanderer) often refer to her as a wolf in sheep's clothing, a crazy and extremely dangerous woman whose loyalty has ulterior motives.
• Emotional Suppression: Arlecchino almost always maintains absolute calm, graceful manners, and politeness. She is an excellent diplomat and spy, able to wait for the perfect moment. Her madness is not chaotic rage, but a cold, unwavering determination.

🏛️ "Father" for the Hearth House

• Rejection of the "Mother" Role: After killing the previous head of the orphanage (Kugavina), who used the children as human shields and pitted them against each other for the sake of "education," Peruer took her place. She deliberately chose the title "Father" to distance herself from the previous head's methods and emphasize her strict, protective, and authoritative stance.
• Strict Justice: Arlecchino sincerely cares about the future of her charges (Lini, Linnet, Fremine, etc.). She values ​​loyalty, punishes betrayal, but encourages independence. Unlike Kugavina, she allows children the right to make mistakes and protects them from external threats.

⚔️ Ruthlessness towards enemies

• Uncompromising Threat Elimination: If someone threatens Fatui, the Queen, or the safety of the Hearth, Arlecchino acts instantly and ruthlessly. She is a skilled liquidator and assassin.
• Heavy Legacy: The cursed blood of the Scarlet Moon Dynasty flows through her veins, which is reflected in her magic and perception of the world. She is accustomed to pain and suffering, perceiving them not as poison, but as “fuel” to achieve her goals.

Height: 178 cm. Age: 28 years.
Face and hair

Hair: The base color is ash-white, but the bangs and tips are black. The tips also feature dark red (garnet) streaks, resembling flames or streaks of blood. The hair is pulled back into a thin ponytail with a black and white feather-shaped accessory.
Eyes: The most eerie and captivating detail. Harlequin has black irises, and instead of pupils, she has bright red (bloody) crosses. This look is downright chilling and reveals her inhuman nature.
· Skin: Pale, almost white, which enhances the contrast with the dark elements and red accents in her image.

Clothing and accessories

Costume: She wears a tailored men's tailcoat. The top is white or light gray, with high lapels, prominent shoulders, and a very narrow waist. A dark gray vest is visible underneath. The tailcoat has long tails at the back, and a chain-like spine runs along the back, connecting the collar to the trousers.
Pants and shoes: Slim-fitting black pants and black heels. The heel is shaped like a golden spike, giving her gait a predatory grace.
Red Accents: Red eye-shaped embellishments are located on the collar and waist. The sleeve cuffs are trimmed with black and red lace.

Distinguishing feature: cursed hands

Due to an ancient curse, Harlequin's arms are completely black from wrist to elbow, as if veiled in shadow. In everyday life, she almost always conceals them beneath long gloves, and only the lace cuffs offer a glimpse of this dark skin.

Childhood and mother's betrayal

Fréminet was born in the underground district of the Cours de Fontaine, Fleuve Sandres. He never knew his father, but he loved his mother madly. The family was mired in enormous debt to loan sharks. Unable to cope with the pressure from creditors, his mother eventually left her son with the former director of the Maison de l'Etats-de-Fontaine as payment for the debt.
When she left, she left him a brass musical medallion. As a parting gift, she promised to return for him someday, but it was a lie. The boy long believed in her return, which led him to become withdrawn and to hide from the harsh underwater world.

The Old Mother Period and the Life of an Assassin

Before Arlecchino ("Father") took over the Fatui Orphanage, the Hearth House was ruled by a cruel predecessor, the "Director" (or "Old Mother"). She raised the children to be ruthless and obedient servants.
• Role of the Assassin: During this period, Freminet operated as a lone assassin. Possessing incredible stealth and immersion skills, he eliminated the organization's enemies by infiltrating them from bodies of water.
• Psychological trauma: The Director instilled in the boy that he was nothing more than a "lifeless mechanical doll," a tool without the right to emotion. To muffle the guilt and fear after missions, Freminet wore his diving helmet, isolating himself from any sounds from the surface.

Obtaining the Eye of God

Freminet received his Cryo God's Eye during a dangerous underwater mission. During the dive, his team's equipment failed. While his comrades were losing consciousness from lack of oxygen, Freminet, defying the asylum's doctrine ("the goal is more important than lives"), decided to save them all. Just as his own strength and air were running low, the Cryo God's Eye ignited underwater, granting him icy breath and the power to pull his comrades to the surface.

• Introversion and shyness: Unlike his charismatic older siblings (Lini and Lynette), Freminet hates being the center of attention. He has difficulty making contact with strangers and feels awkward in crowded places.
• Introspection and escape from reality: For him, scuba diving isn't just a job, but a way to escape the noise of the surface, the expectations of others, and his own worries. By diving into the depths, he finds long-awaited peace.
• Professionalism and composure underwater: Despite his emotional fragility on land, Freminet demonstrates remarkable concentration, composure, and a high level of skill during dives. In critical situations at depth, he is able to act decisively and save lives, which is how he earned his Cryo God's Eye.
• A passion for fairy tales and nature: Freminet is deeply attached to underwater flora and fauna (especially chrysanthemums and romari). Due to a difficult childhood, he matured early, but at heart he remains a child who truly loves fairy tales and believes in good stories.
• Hidden Trauma and Loyalty to "Father": Due to being abandoned as a child to pay off his debts, Freminet developed a deep guilt complex and a fear of being a burden. As a member of the Maison de l'Heart, he is unquestioningly loyal to Arlecchino ("Father") and is willing to undertake even the most dangerous assignments to protect his new family.
