The narrative centers on Kinoshita Suguri, a nine-year-old third‑grade student who adores animals and crafting jewelry. While shopping for supplies in the bustling market, she spots a peculiar stone. Believing it would add charm to a bracelet, sparkle on wrist, she picks it up and encounters a being called Kappy. Kappy is actually the three‑year‑old sovereign of Kapimeshia, who rules with gentle kindness.
