Trapayne

Ms. Trapayne, also romanized as "Madam Trapine", is the radio operator of Seraphix, a division of Chaldea Security Organization. During the incident where Kiara takes over, she is one of the four last survivors with Arnold Beckman, Mable Macintosh, and Holly. She acted as the secret helper of BB who, despite being cowardly, managed to reach the communications room alone and send out an SOS to Chaldea even while being decomposed into data. BB buried her with care out of respect for the strength of humanity Trapayne showed in her last moments. After the defeat of Kiara, BB makes the event an imaginary numbers phenomenon, so it is if "nothing had happened" and all staff besides Kiara are saved.
