Zazie is a young Letter Bee who was introduced in chapter seven. He is very skilled at killing Gaichuu. Zazie's parents were killed by Gaichuu when he was young, leading him to become a Letter Bee so that he could seek revenge against all Gaichuu. Because he is so focused on killing Gaichuu, delivering Letters is of course of little interest to Zazie. Zazie is very fond of cats. At one point, he was mad at Dr. Thunderland because he thought that the Doctor killed an alley cat he was feeding. However, when he found that Dr. Thunderland quarantined the cat because of a disease, Zazie forgave him.
