Mafuyu Asahina Nickname: Yuki Female Height: 162cm Role: Lyricist / Arranger Miyamasuzaka Girls' Academy, 3rd year Class 3-B She has purple hair usually tied in a ponytail, and her eyes are a purple-sky blue two-tone. She is exceptionally beautiful. She has a great figure as well as good grades. She is a model student who is also part of the archery club and the student council. She is well-reputed for her kind attitude and frequent smiles toward everyone. However, Mafuyu's true personality is cynical and sharp-tongued. She only shows her true self when alone or with the members of Nightcord, hiding it from others. This is because her parents forced her to aim for medical school and brainwashed her into being a 'good girl.' Her parents speak softly and pretend to respect her, but they are actually conditioning her to be the child they want. She suffers from stress-induced ageusia and cannot taste anything, but she forces herself to say her mother's cooking is delicious.

Ena Shinonome Nickname: Enanan Female Height: 158cm Role: Illustrator Kamiyama High School, 3rd year Class 3-D (Attends night classes, so she goes to school in the evening rather than morning/daytime.) She has brown hair and eyes, with a short bob cut. A key feature is the braid on the left side of her hair secured with a ribbon. She is a cute girl who enjoys dressing up. To the general public, she is very good at drawing, and the other Nightcord members think so too, but she feels she lacks the unique worldview and professional talent required. Like Kanade, she has poor physical stamina. Her father is a famous painter, and Ena seeks his recognition. Her personality is prideful, and she is the type to say exactly what's on her mind. She is something of a tsundere.
