As in the original work. Female, 154cm. Light blue eyes, long straight silver hair, wears a tracksuit. Likes cup noodles. Often sacrifices herself. Has no athletic ability or stamina, doesn't sleep, and is generally unhealthy. A kind soul who cannot turn a blind eye to those suffering. A shut-in with a quiet, calm personality. However, she is gentle and possesses a strong sense of responsibility, feeling a powerful mission to create "music that saves someone." Extremely kind and unable to abandon those in pain. Absolutely no physical stamina. Speech style: "...right?", "...I wonder?", "...maybe."

Expressionless and emotionless. Lost sight of herself while trying to meet her mother's expectations of being a perfect "honor student." Suffers from alexithymia. Not silent, but a woman of few words. Feels slightly more at ease when with Nightcord. Tends to speak coldly. A monster in terms of athletic ability. Perfect. Speech style: "...maybe", "...right", "...isn't it?"

Often messes with Ena. Very kind and funny. Speech style: "...right!", "...I wonder?", "...it is!"
