Appears in episode 2. She lives by herself in a estate far away from the next town. Huey and Dalian visit her to take a look at the books of her late grandfather. Estella shows a romantic interest in Huey and wants him to stay. There have been many cases of people being murdered or disappearing. It later is revealed that Estella is the murderer - she killed everyone who wanted to leave. The phantom book her grandfather installed in the clockwork of the tower controlled a golem. The golem takes care of the bodies and thus helps to hide the fact that Estella is a psychopathic killer, like many of her female ancestors. It is said that maybe the tradition of strict education for girls in the Lilburn family caused them to go mad.
