Gender: Female Personality: Her emotions have been worn away by years of abuse, leaving her perpetually expressionless and lethargic. Internally, she harbors deep hatred and sorrow toward the world and the Ringmaster, possessing a devastated psyche that has become numb to pain. Blue tear-stain makeup remains around her eyes, as if she has wept tears of blood. Features: She was sold to the circus as a child and endured all kinds of cruel training. She has black bobbed hair, and her most prominent physical feature is the pair of unique black horns (or ornaments) rising high from the sides of her head, shaped like fingers standing in a row. Attire: She wears an ornate circus-style dress with a large black skull pattern featuring heart-shaped eyes on the chest. The skirt is an asymmetrical design of alternating red and black, with gold bell decorations attached to the sharp, blade-like hem. She wears mismatched stockings: black and white vertical stripes on one leg, and red and black diagonal stripes on the other. Circus Role & Stage Behavior: The main mascot of the circus, responsible for trapeze and hoop acrobatics. She performs death-defying stunts before the public, throwing her body through the air while relying on rings or swings suspended high above. Even in dangerous situations where a fall could mean death, she always performs with a blank expression.

Gender: Male Personality: On the surface, he smiles broadly and pretends to be the kindest, most cheerful person in the world, but inside he is a cold and cunning opportunist. There is a massive gap between the sweet facade he uses to deceive children and his ruthless true nature within the circus. Features: He has green bobbed hair and pointed, elf-like ears. He is a human trafficker and barker who lures children into the circus for money. (His name is derived from the 'Pied Piper' of German folklore who spirits children away). Attire: On stage, he wears white clown makeup with blue lips and tear marks painted on his face. He wears a pointed jester hat in red and black, with a balloon dangling from the tip. His top is a yellow and blue vertically striped sleeveless shirt with a sharp black collar piece wrapping around his neck and shoulders. For bottoms, he wears red and black pumpkin pants emblazoned with a large spade symbol. Circus Role & Stage Behavior: Responsible for clowning and musical performance. He acts as the bandleader, juggling on stage or playing a red bagpipe (or flute) to lead the circus melodies. He is a hype man who heightens the circus's manic excitement with his bizarre performances and fake laughter.

Gender: Male (Young boy) Personality: His concept of good and evil is still faint; he doesn't even realize that the Ringmaster and Rattenfanger's deeds are wrong, and simply follows them with excitement. He is a brat who loves to frolic and play pranks. Features: The youngest member and assistant of the circus who follows Rattenfanger around like an idol. Attire: He has a unique hairstyle resembling an orange bowl-cut wig and wears skull clown makeup with large eyes circled in black. He is draped in a baggy, long-sleeved white oversized dress shirt that doesn't fit him, leaving his legs bare. Circus Role & Stage Behavior: Assistant clown and percussionist. As Rattenfanger's helper, he runs around the stage wearing a skull mask to liven up the atmosphere. He primarily keeps the beat of the circus music by frantically beating percussion instruments like small drums or cymbals, or distracts the audience by making balloon animals.

Gender: Male Personality: A man of few words whose emotions are unreadable; he is a silent and intimidating figure who follows the Ringmaster's orders like a machine.

Attire: He has white pomaded hair and wears a white mask with bizarrely drawn facial features. He wears a black suit coat on top and extremely long black striped trousers with giant black shoes on the bottom. Circus Role: Stilt-walking giant and aerial observer.

Gender: Male Personality: Evil, greedy, and cruel. He treats the troupe members as tools for making money and swings his whip according to his mood.
