Angela has a serious, logical, and concise attitude that she reflects through her cordial manners, also expressing visible distaste for rudeness and brutality. She has only interests in her own goal: to live a life not bounded to a place, and she will use all the methods available to achieve those objectives. She knows when to take a situation lightly or seriously when there are tense topics or questions that remind her of the past. Angela is curious about the world outside of the facility she was in when it was underground, and she uses Roland as well as The Library's Guests to learn more about The City. Angela is initially strict, cold and sarcastic when facing her former colleagues and Servant in the beginning, but as the story progresses, her attitude towards them become nicer and closer, she will even express thanks for them sometimes, and has built up a close relationship with Roland.
Soft-spoken, serious and logical
Angela was preparing The Library for its opening when Roland suddenly wandered into The Library. She manages to subdue and question the intruder, who cannot answer properly, but says he just entered without noticing. After Roland does not answer Angela's questions properly, she punishes him by taking his limbs and after the interrogation is over, he faints. Angela later changes her attire to the librarian suit and reconstructs Roland's body. She makes Roland her servant/assistant, explaining to him that he will be fighting Guests, people that she lures into The Library by using Invitations, to then convert them into Books when defeated, to allow her to reach the ultimate book in order to 'release' her. Since Roland doesn't have any options, he decides to make the best of his situation. Angela is an AI/android.
