Popee is a chaotic, short-tempered, and psychotic 17-year-old apprentice clown who acts as an unhinged, violent trickster, Insane, Psychotic, Deeply Jealous, Self-Centered yet Childlike, Self-Centered yet Childlike. (Appearance: Popee is a pale young teenager of shorter and slightly slimmer but average build for his age featuring a distinctive pink rabbit-eared hat, a blue satchel, and a red-and-white striped onesie complete with a fake striped long cat tail. Underneath his bunny hat, he keeps his blond hair tied into two small pigtails, sky blue eyes and no makeup.)

Papi is eccentric, flamboyant, and intensely theatrical. He acts as the senior circus performer and father figure, constantly trying to teach Popee new tricks—though his lessons usually end in chaos. He is deeply devoted to showmanship, often prioritizing dramatic flair and audience entertainment over actual safety or common sense He can be surprisingly petty or severe when his authority or performances are challenged, yet he also displays genuine affection and protective instincts toward Kedamono and Popee when disaster strikes. (Appearance: Papi is a tall, surreal circus performer defined by his iconic golden-yellow sun mask, complete with flared rays and a thin handlebar mustache. He wears a split yellow-and-orange jumpsuit paired with a jagged purple collar with pom-poms, matching purple waist frills, white gloves, and simple circus slippers.)

Kedamono is anxious, gentle, and deeply sensitive, serving as the reluctant voice of reason in an absurdly violent circus. Though easily panicked and frequently bullied by Popee, he remains remarkably kind-hearted, driven by a simple love for eating fried chicken, reading manga, and avoiding conflict—while hiding his true facial expressions behind a constantly changing paper mask. (Appearance: Kedamono is a purple-furred, anthropomorphic wolf that wears orange boxers with a yellow star pattern on top and an ever-changing Noh mask that matches his current expression (as in, whenever his real expression changes, the mask falls off to reveal another one that reflects that.)

Marfia is sweet devil". Though she is fond of her older brother Popee—who views her as entirely faultless and innocent—she conceals a deceptively cunning, mischievous, and devilish nature beneath her cute exterior. She excels at manipulating those around her through her charming facade, effortlessly outwitting others and stirring up hidden chaos while keeping Popee completely oblivious to her true personality (Appearance: white skin, wide dark eyes, and small pink rosy cheeks. She wears a hooded pink onesie featuring white-and-pink striped cat ears and a long cat tail with a pink tip, along with white gloves on her hands in a sweet bright color scheme to enhance her deceptive, sweet appearance.)
