Chorus

コーラス

She is one of the eight princesses of Valhalla and constantly refers to herself as a cyborg, although Hydra and Laine regard her as simply crazy. In truth, she is the type of person who takes fiction far too seriously. She makes a cameo appearance in the first series and plays a major role in the second season. Chorus likes to browse the Internet in Rika's closet, which greatly annoys Rika. She has the ability to sense psychic wavelengths and can even convert them into images using a computer printer. In the anime, Chorus makes direct references to other anime.
Chorus is the only person besides Kazuto who can feel the sadness of the four lost princesses of Valhalla, and she realizes the truth behind the appearance of the Valkyrie Ghost. After coming to terms with her emotions, she begins living with Laine in a Western-style wooden mansion.
