Sebastian Michaelis

Tanaka. An old butler who mysteriously survived the fire at the manor that killed Ciel's parents. Rarely speaks to others, and spends most of his time drinking green tea. Comes out of his introspection during key moments to convey unimportant historical facts to the viewer. In the anime, he keeps a diary in which most of the important events in the Phantomhive family's history are described.

Bardroy (Bard). The cook of the Phantomhive family. Very kind, but a bit abrupt and rude. In the past, he was a soldier, and during his last battle, he was the only survivor, as he realized the danger of the chosen tactics and was able to escape, after which he was hired by Ciel and Sebastian. Bardroy is always happy to help anyone and works hard, trying to be useful.

Finnian (Finny): A gardener who knows absolutely nothing about gardening. Finny has superhuman strength. He was subjected to experiments to increase his physical strength, as a result of which he was able to escape, after which he was immediately hired by Sebastian.

Meiling. A clumsy maid from the Phantomhive estate. Wears glasses because of her incredible farsightedness. Categorically does not want to take them off or change them for new ones, as these were given to her by Ciel on her first day of work. In the past - a killer. Hired on Ciel's orders.

Snake. The Phantomhive family's lackey. The former snake charmer of the Noah's Ark Circus. Snake is able to understand snakes, allowing them to speak through him, and is rumored to be half snake himself. Snake is a quiet, shy, and taciturn young man. When he does speak, it is usually through the eyes of one of his snakes.
