Di Gi Charat, also known as Dejiko, travels to Earth with her companions Petit Charat (Puchiko) and Gema as part of her training to become a full‑fledged princess. Their journey ends abruptly when they crash in a small Japanese town, where they encounter the Omocha brothers, who spend most of their time admiring Puchiko’s cuteness, and the elderly couple Mr. and Mrs. Ankoro, renowned for their homemade Japanese sweets.
