Duke

A familiar serving Chocolat. A red and black striped frog with a sloppy and unreliable personality. Ends sentences with "...kero." In human terms, he is 30 years old. His hobby is dancing, and he dreams of becoming an idol singer. There is a mystery about his true identity, as even Pierre has said, "You are..."

His true identity is Poivre Meilleure, a skilled magician and the younger brother of Cinnamon Meilleure, making him Chocolat's uncle. However, Poivre's existence is not mentioned in the anime (he appeared once in human form but was not revealed to be Duke). Additionally, when he becomes human, his usual clumsiness disappears, and he often makes sharp retorts to Chocolat.
