Di Gi Charat, commonly called Dejiko, is an alien princess from Planet Di Gi Charat. She is the daughter of the planet's Great Chief and Queen, with a younger sister named Petit Charat (Puchiko). Her family was targeted by the Analogue King and Queen, leading to Dejiko and Puchiko being sent to Earth for safety. They arrived with their guardian, Gema, and took residence above a Gamers store in Akihabara after the manager offered lodging in exchange for assisting with store operations. Dejiko's real name is Chocola, though she dislikes chocolate and prefers broccoli. Her father gave her the title "Di Gi Charat" to signify her royal status as heir. Dejiko's appearance features bright green hair, large green eyes, and cat-like attributes including a white cat-eared hat, a tail, and paw-like sleeves and socks. Her signature outfit is a blue maid dress adorned with three bells and ribbons. This design persists across most media, including the original anime, OVAs, and later series like *Di Gi Charat Nyo* and *Reiwa no Di Gi Charat*. Variations occur in spin-offs: *Panyo Panyo Di Gi Charat* depicts her in a plain pink dress with matching shoes, appearing younger. *Winter Garden* portrays her as an adult with less vibrant hair, dressed in human clothing like a plaid skirt and brown jacket, while retaining subtle nods such as a cat-themed headband. A 2008 redesign briefly altered her eyes to red and modified her maid dress before reverting in 2013. Her personality merges a cute exterior with volatility, laziness, and self-centeredness. Quick-tempered, she often fires destructive laser eye beams at those who annoy her and shows little respect for others, including fans. Despite this, she deeply cares for Puchiko and acts protectively toward her. In *Panyo Panyo Di Gi Charat*, her characterization shifts toward spreading happiness and kindness, though she retains stubbornness. *Winter Garden* further evolves her into a mature, soft-spoken maid café employee displaying responsibility and empathy, particularly toward Puchiko. This series also introduces her romantic relationship with Takurou Senba. Across all iterations, she ends sentences with "-nyo". In the *Summer Special 2000*, Dejiko confronts rival Piyoko and the Black Gema Gema Gang, who open a competing store across from Gamers. Initially dismissive, Dejiko grows concerned when loyal customers defect. Her competitive nature drives schemes to undermine Piyoko’s store. She demonstrates loyalty to Gamers by thwarting Piyoko’s destructive plans, including an attempted demolition. Her interactions highlight trademark aggression—like blasting non-purchasing customers—and fleeting teamwork with the Black Gema Gema Gang during seasonal events. Her abilities center on laser eye beams generated from intense anger or frustration, capable of destroying buildings. This power remains consistent across media but varies in use: frequently weaponized in the main series, rarely appearing in gentler spin-offs like *Panyo Panyo Di Gi Charat*. Relationships include a rivalry with Rabi~en~Rose (taunted as "Usada") and a protective bond with Puchiko, whom she guides in *Winter Garden*. She also shares a dynamic with guardian Gema, who endures her outbursts.
