Beatrice

Beatrice (ベアトリス) is Natsuki Subaru's contracted Artificial Spirit and a member of the Emilia Camp. She used to be the caretaker of the library until its destruction.

Appearance
Beatrice is a petite girl with long cream colored hair that she has tied in two twin drills along with blue eyes that have a butterfly pattern at the center. She wears a frilled dress with pink ribbons, tights, and shoes. A tiny crown lays latched upon the rear right side of her hair, with a butterfly-shaped ribbon joining her cape at her sternum.

Personality
Beatrice generally looks down on others and is bad at dealing with people who try to get close to her. Despite being full of bravado, she's a lonely person, and is softhearted beyond her perceived stubbornness. She is affectionate towards Pack because of their similarities and favors him over the others in the Roswaal household. She has a distinct way of speaking, adding kashira (かしら, "I suppose") at the end of her sentences.

History
Around 400 years ago, Beatrice was created by Echidna. She helped her with her experiments, such as the Sanctuary Barrier, though she wasn't told everything as she didn't know that Lewes Meyer would be sealed in a crystal. Sometime later, Echidna ordered her to stand guard over the library while she waited for "that person", an order which she diligently followed.

Abilities
Yin Magic: Beatrice is a master at Yin Magic and is capable of casting all Yin Magic, even those that have been long since forgotten by people in the present. Her power is far stronger than Subaru's own Yin Magic and she is capable of doing various things through it such as teleporting, freezing time, tearing space, and fixating her existence, however as she is currently low on mana she can't use most of her magic.

Contract Spirit: Beatrice is currently contracted with Subaru, though according to her he isn't a true Spirit User. She also has a terrible mana consumption rate and formerly got around his by draining mana from people in the mansion using the library as a medium. As she is an Artificial Spirit, she also has several conditions Subaru is forced to follow:
 * Subaru cannot form a contract with other Spirits
 * Beatrice cannot restore mana on her own
 * Beatrice cannot use the mana in the atmosphere
 * Beatrice can only drain mana from Subaru
