Petit Charat, widely called Puchiko, hails from Planet Di Gi Charat. Her connection to Dejiko begins ambiguously; early sources label her a companion or sidekick, while later media confirms they are biological sisters, sharing royal parents from their home planet. One narrative depicts Dejiko rescuing Puchiko from a hole, prompting Puchiko to follow her rescuer out of gratitude. Puchiko appears five or six years old, standing 103 cm tall with brown hair, dark brown eyes, and distinct cat ears. Her classic outfit is a sailor-style uniform featuring a white top, dark skirt, and green tie, often adorned with small cat bells in her hair; she initially goes barefoot. Her design evolves across series: in *Panyo Panyo Di Gi Charat*, she wears a red dress with dark blue pants and orange shoes; in *Di Gi Charat Nyo*, she sports a blue dress and light blue tie; and by age 15 in *Winter Garden*, she appears taller in a navy blue school uniform, now wearing socks and black shoes. Her personality centers on a stoic demeanor and minimal speech, frequently ending phrases with "nyu." She maintains calm amidst chaos but wields a sharp tongue if provoked. Puchiko harbors an interest in the occult and seldom shows anger, though intense frustration can unleash her flawed "Me Kara Beam." This eye beam, akin to Dejiko's, often misfires due to her generally placid nature compared to Dejiko's volatile emotions, producing chaotic effects like sludge instead of coherent energy. Stranded in America during *Di Gi Charat Summer Special* after failing to signal a bus driver, Puchiko's predicament forces Dejiko to retrieve her, highlighting Puchiko's reliance on her sister in unfamiliar settings. Her role matures in *Winter Garden*, where she briefly works at McDonald's and demonstrates increased maturity by mediating conflicts, such as reconciling Dejiko with another character. Her temperament also softens, showing less of her earlier sarcastic edge. Her abilities include the inconsistent Me Kara Beam, which rarely functions effectively only under extreme pressure. She also exhibits unexpected physical aggression when antagonized, such as ripping hair or destroying property, though these outbursts remain uncommon.
