Qiqi has a quiet, yet polite demeanor when dealing with customers at the pharmacy. As a zombie, Qiqi has trouble retaining memories and can quickly forget about people if she doesn't continually reinforce herself with an impression of them, using her Vision to protect those she holds dear. Due to her undead nature, Qiqi has a relatively flat voice and is unable to convey most of her emotions to others, nor does she have a particularly strong sense of smell. She prefers cold weather, as the heat reminds her of death and her flesh begins to decay if she stays too long in such places.
