Chimumu is the spirited magician partner of Hina Yayoi, born July 9 under the Cancer zodiac with blood type A—a birthday shared with an unnamed character from another series. Her animal form manifests as a green hamster adorned with a white star marking on her chest, rosy cheeks, pink sunglasses, and a star-tagged collar. In human guise, she sports white and cyan hair styled into conical buns, paired with striking orange and purple eyes. Her speech peppers phrases with a signature "chimu." Fiercely energetic and prideful, Chimumu thrives on competition, channeling unwavering support for Hina’s ambitions. Though occasional doubts about her own value surface, Hina’s steadfast affirmations reinforce their bond. Her rivalry with Myamu, another magician partner, ignites frequent clashes, their interactions crackling with competitive tension. Chimumu’s wardrobe evolves across media: The "Manamana Chimumu" coord debuts in anime episode 51, blending denim with hearts and stars. In-game appearances include the "Primagi Check Chimumu" (Chapter 8) and "Chimumu Casual" (Chapter 2), each emphasizing her vivid teal theme, star motifs, and whimsical flair. Beyond magic, she savors jellybeans as her favorite treat.
