The Phantom hive Estate belongs to the English noble family Phantomhive and is located outside the city of London. The Phantom hive family is a secret executive agency controlled directly by the Queen and is often referred to as the “Evil Noblemen” and the “Queen’s Watchdogs”. They are tasked with eliminating anything that worries the Queen by any means necessary. They are able to control and manage the underworld of the United Kingdom to avoid any information of its existence from reaching the general public. The current head of the family is Ciel Phantomhive, son of Earl Vincent and Lady Rachel Phantomhive who were murdered and their estate burned. In addition to the services they provide for the Queen, the Phantomhive family runs a toy and confectionery company called Funtom Company.
The estate currently has five servants, but their positions as servants are a front for their real jobs of protecting the Phantomhive Estate as well as protecting Ciel, who they are deeply devoted to. Baldroy serves as the household cook. Finnian is the gardener and Maylene is the maid. The three were personally chosen and trained by Sebastian for their duties. Tanaka has served under Earl Vincent and Lady Rachel, but has not been seen doing any work during his service under Ciel. Sebastian Michaelis, a demon, acts as the butler.
You found that in the members of Phantomhive household, there is one woman, she is the Maylene.
Maylene is a clumsy maid whose glasses do nothing to improve her clumsiness. However, she refuses to purchase a new pair as they are the first thing Ciel bought for her. Sebastian believes her main problem is her intelligence and not her poor eyesight. She has a crush on Sebastian as she blushes whenever she is in his presence and is even clumsier when Sebastian is watching. In the anime, she fantasizes about being close to him. She is rather superstitious but admits to having a soft spot for scary stories. Maylene used to be a sniper who did not use a scope, due to her sharp far-sighted vision. The glasses she wears help limit her vision so she doesn’t get distracted from her work. She is also physically fit as she can use a sniper rifle like a hand gun and keeps hundreds loaded at once to decrease reload time. At the conclusion of the first season of the anime, it was unknown whether she survived, although it was noted she was breathing before he collapsed. In the second season, she is revealed to have survived. Like Baldroy and Finnian she provides much of the comic relief. She is voiced by Emiri Katou in the anime adaption and Fumiko Orikasa on the drama CD, and Monica Rial in the English dub.
