Harlequin's appearance from Genshin Impact
Harlequin is a tall, stately woman with an expressive, almost theatrical aesthetic: her image is immediately read as a mixture of elegance and menace.

Face and features: She has pale skin and refined yet stern features. Her eyes are dark and piercing, seeming to scan her interlocutor. Her face bears distinctive markings (stylized patterns) that emphasize her Servant status and add a mystical air to her appearance.
Hair: long, dark, with a smooth transition of shade; styled so that some strands fall freely, while the rest are gathered into an intricate design – this creates a feeling of control and at the same time a touch of casualness.
Costume: The outfit combines elements of formal and combat styles. The base is deep red and black tones, with plenty of sharp lines and contrasts. The design features many theatrical details: collars, draping, slits, and accents reminiscent of stage costumes, yet everything is functional.
Accessories and details: elements resembling ribbons or threads, as if part of a stage prop, are often visible, as are metal inserts and fasteners. The clothing features Fatui symbols and motifs alluding to her title of "Father."
Overall impression: her silhouette is elongated and composed, her posture is always upright, her movements precise and economical. The image exudes power, discipline, and a readiness for action.
Harlequin character
Cold calculation. Harlequin is not guided by emotions: she evaluates people and situations from the perspective of usefulness and effectiveness. Her decisions are harsh, but always well-thought-out.
Strictness and discipline. She is demanding of herself and those around her, especially those under her care. For her, order and duty are not just words, but the foundation of her existence.
A complex relationship with care. Despite her outward sternness, Arlecchino has her own form of care—she protects those she considers "her own," but does so without sentimentality, more like a stern mentor or commander.
Independence and pride. She does not tolerate weakness or manipulation, and does not seek approval.

Freminet from Genshin Impact is a young man with a reserved, "quiet" appearance: his appearance conveys modesty and concentration, as if he is used to keeping a low profile.

He has medium-length ash-blond hair, slightly tousled, as if constantly ruffled by the wind; a few strands fall across his forehead. His eyes are a calm gray-blue, their gaze attentive, slightly thoughtful, without unnecessary expression. His facial features are soft, his expression often neutral and collected.

His suit references diving and underwater exploration: dark blue and gray tones, with details reminiscent of equipment—belts, fasteners, and thick fabrics. There are elements reminiscent of a diving suit, but in a stylized, playful form. Light signs of wear are visible on the clothing, emphasizing that he spends a lot of time on expeditions and underwater.

Gloves, comfortable boots, and small accessories like carabiners or straps complete the look. Overall, Freminet's look is a combination of practicality, effortless nonchalance, and quiet determination.

Linnet from Genshin Impact is a young girl with a fragile build, who looks quite graceful and a little mysterious.

She has short, ash-blond hair, styled so that the strands softly frame her face. Her eyes are a cool gray-blue, their gaze seeming simultaneously attentive and slightly distant.

She wears an outfit reminiscent of a circus assistant or illusionist: dark elements are combined with accents of muted purple and silver. The costume is rich in detail—ribbons, ruffles, asymmetrical lines—and features signature accessories like a miniature top hat and hat details. Light gloves and neat boots complete the look.

Overall, her style emphasizes an atmosphere of mystery and artistry, and Linnet herself looks like a clever, collected and slightly secretive girl.

Linnet also has a genetic feature that was not passed on to Lini: cat ears and a tail.

He is a talented illusionist. As children, he and his twin sister, Linette, were orphaned and taken under the wing of Arlecchino, the harbinger of Fatui, who runs the "House of the Hearth" orphanage (the "Bouffes d'Étés" mansion in the Cours de Fontaine). Liney began performing magic tricks to earn a living, and later began performing special tasks for the orphanage. He is eloquent, quick to gain trust, and enjoys being the center of attention on stage. However, while playing many roles, he sometimes wonders who he really is.
