Beatrice

Beatrice (ベアトリス) is a member of the Emilia Camp and the former caretaker of the Forbidden Library at Roswaal's Mansion, until its destruction in the climax of Arc 4. She is one of the main supporting characters in Re:Zero, with an especially large role in Arc 4.

She is an artificial spirit created by the Witch of Greed for unknown reasons. 400 years ago, she was told to wait in the library for "That Person" who would grant her salvation. However, in Arc 4's climax, Subaru convinced her to live and she became his contracted spirit.
