Duke  

Poivre

Duke is depicted as a red and black striped frog who serves as Chocolat's magical familiar. However, it seems that he doesn't always behave as expected, as you frequently observe him lounging around on your bed or sleeping instead of helping you collect hearts. Instead of providing advice, Duke often makes discouraging comments, ending his sentences with -kero, which is similar to the sound "ribbit" in English. Additionally, he has a tendency to fight with Blanca and refers to her as a rat. This behavior can be seen in the manga.
