A large orange cat who serves as Zhenyi's companion and personal guard. Ju Zi is intelligent and observant, often following Wang Xichen and noting his mood. She worries about Zhenyi putting things in her mouth and slaps her hand back. She is described as elegant in her steps despite her mischievous behavior, such as scratching Zhenyi's pigtails. She had a nightmare comfort experience where she landed on Zhenyi's forehead during a bad dream. The narrative suggests Zhenyi may have been a cat in a past life, or that whoever raised her resembles her, since Ju Zi raised Zhenyi.
