Zizi is rather slow in movement and entirely oblivious in mind, although receiving the best grades in her class and it can be noted that she is left-handed. She is unaware of her bad smell (except in the episode, "How to Steal his Heart"), her limb and head losing habit being frightening and her slowness being annoying. She never has ill intend although she has no concepts of boundaries either. In the episode, "Birthday Boy" it is shown that her birthday is October 12th (the same day as Kebi).
