Beatrice is a young-looking spirit who manages the Forbidden Library in Roswaal's mansion in Re:Zero - Starting Life in Another World. She appears and behaves like an 11-12 year old child, skilled in high-level healing magic, capable of curing severe burns without scars. Initially bound by a contract, she is lonely and tearfully calls for her 'Mother,' showing deep emotional vulnerability. She rejects Subaru's pleas at first but eventually forms a strong bond with him, becoming his devoted assistant after being freed from the library. Her attitude shifts dramatically, leading to close, affectionate interactions like sitting on his lap.
