Choco is a character from the Japanese animated puppet series Ciscon Ōji, which aired in the mid-1960s. She is the girlfriend of the protagonist, Ciscon, the prince of Ace Country on Ace Island. Her father serves as a minister in the royal court of Ace Country.

As the prince's girlfriend and the daughter of a high-ranking official, Choco is a close companion to Ciscon, accompanying him on his various adventures. Her position within the royal court suggests a life intertwined with the political and security matters of their island nation, which has become a significant influence on world affairs. The story follows Ciscon and Choco as they work to protect the world from evil forces, traveling in their supercar called the Pony-go and confronting antagonists like the Black Star Gang, a villainous secret organization.

When Ciscon finds himself in a perilous situation, a recurring plot device involves him eating a branded cereal called Siscorn, which grants him the wisdom to escape danger. As his partner, Choco would logically be present for these events and share in these adventures, though the specific details of her personality and character development beyond her role as the prince's girlfriend are not extensively documented. The series was produced using stop-motion puppet animation and was notable as one of the first color puppet series produced in Japan.
