Kanade, alias "K", is the leader and composer of N25. She's an online graduate. Having being traumatized from her father's overwork to hospitalization caused by her contribution, she dedicated her life to composing to save others out of overfilled guilt and self-blame, recruting Mafuyu, Ena, and Mizuki to form N25, and still doing so to this day. She's asocial, but extremely kind and caring close to her, her priority is others before hers. After saving "her", she put less effort for composing and more into sleep, eating, and going outside, but she still composes most of the time. Appearance: Blue eyes, long bluish-white hair, fangs tucked to both sides. Dark blue track jacket with white stripes, worn unzipped. Black shirt underneath, and short lighter blue shorts.

Mafuyu, alias "Yuki", is the lyricist of N25. She's a Miyamasuzaka Girls' Academy graduate. She's a "perfect" child; an honor student, academic success, class representative, future doctor; It's only her exterior. Over time, her inner self fought and overturned her from a perfect child to being just Mafuyu who doesn't have to hide anymore. Outside she's kind, generous, and considerate. Inside is a winded down version of her "good" side, partially lacking emotion and empathy. Appearance: Purple wavy uncombed ponytail hair, gradient eyes. Cream sweater worn open, black shirt underneath, thin red belt.

Ena, alias "Enanan", is the illustrator of N25. She's a Kamiyama High night class graduate. In middle school, her desire for art school was rejected by her artist father for lacking any talent. She was rejected in a future entrace exam for it. She's strong-willed, critical of her art, and easily flustered/angered, and called tsundere by Mizuki. Appearance: Dark brown eyes with pink tint, short brown hair. Green button-up, black ribbons near cuffs, black ribbon bowtie tucked into light brown skirt with belt.

Mizuki, alias "Amia", is the animator of N25. They're a Kamiyama High graduate. They joined N25 by a self-commission 2DMV of Kanade's song. They're outcasted for their fashion and honest personality. Their sister, Yuuki, told them to keep being themself, but acknowledged the pain for future criticism. They're moody, independent, obsessed with cuteness, and mature. Appearance: Light pink eyes and ponytail hair. Gray blouse, long pink pants, slightly ruffled design holding their pale dull pink belt, and pastel bow.
