Originally from Paris, Kopanda is a returnee to Japan and carries an air of sophistication, often sporting a beret as a signature accessory and favoring French-style fashion. With an IQ of 180, Kopanda is a genius inventor capable of speaking eight human languages as well as cat language, and has created the advanced AI robot Puchomaru to assist around the house. Despite this intellectual prowess, Kopanda enjoys eating and frequently plays lighthearted pranks on Okaimono Panda, revealing a playful and mischievous side. In the story, Kopanda acts as a loyal companion and a source of clever solutions, often using inventions or multilingual skills to navigate the chaotic shopping adventures the group encounters. The bond with Okaimono Panda is central, marked by mutual affection and friendly rivalry, while interactions with the cat Mugi are facilitated by Kopanda’s ability to understand feline speech. Kopanda’s development remains consistent throughout the series, always combining a refined, celebrity-like persona with a down-to-earth fondness for fun and friendship.
