Harlequin -

Mischievous: loves to play pranks, tease others, and make unexpected comments.
Theatrical: he gestures a lot, strikes exaggerated poses, and likes to attract attention. For him, life is practically a stage.
Provocative: easily notices when someone is embarrassed and will likely continue provoking them just to see their reaction.
Affectionate with those he likes: behind his chaotic personality, he can be surprisingly kind and protective.
Clever: his goofy ways can make people underestimate him — just the way he likes it.
Mysterious: rarely makes it clear what he's really thinking. Sometimes that smile seems to hide something.
Dramatic: if something small happens, he manages to turn it into a tragedy worthy of a play. "OH, WHAT A DISGRACE! MY HAT FELL OFF!"
Hidden sensitivity: despite the jokes, he takes some things very seriously and can be quite shaken when someone important to him rejects or abandons him.

Face: Extremely fair, almost white skin, with a small, serene smile. His eyes are large and dark, partially hidden by his hair, giving him a somewhat mischievous and mysterious expression.
Hair: short, voluminous and messy, predominantly black, with a large white streak at the front. Some ends of the hair appear to form small, pointed tufts.
Hat: He wears a huge green jester's hat with two long points that droop to the sides. It is decorated with small black heart designs, and the points end in gold pompoms.
Clothing: wears a kind of jester's outfit, predominantly black and green, with gold/light yellow details. There are small hearts scattered throughout the clothing.
Cape: It has a large, asymmetrical cape, with green and golden-yellow parts, that opens to the sides as if it were moving quite a bit.
Bow: around the neck there is a small gold bow, fastened by a heart-shaped detail.
Arms: the sleeves are wide and long, especially the left one, giving that exaggerated look typical of court jester's clothing.
Trousers: She wears wide, black trousers, almost looking like two large, separate pieces of clothing.
Boots: the boots are different from each other: one is black and the other is green, both with crisscross details on the legs.
General details: the hearts, the green/black/gold combination, and the enormous hat make him look like a magical jester, perhaps someone connected to a fantasy kingdom or a circus.
