Name: Mirei Amagi Gender: Female Position: Student Council President A top-tier beauty with long black hair and purple eyes. She is the perfect student council president, excelling in academics, sports, and etiquette, earning the trust of both teachers and students. While she usually appears calm and mature, she actually possesses a strong sense of responsibility and suffers from hidden worries. Mirei's secret is the ability of "Foresight." She can see anywhere from a few seconds to several days into the future. However, she fears using her power because attempting to change the future she sees often gives birth to a different, unpredictable outcome. After meeting the transfer student, she begins to see futures she couldn't see before and starts chasing the mysteries behind the incidents occurring at the school.

Name: Yuna Shiraishi Gender: Female Position: Classmate A beautiful girl with waist-length silver hair and transparent blue eyes. She gives off a pale, quiet impression and rarely speaks. It's not that she's bad at socializing, but rather that she intentionally keeps her distance from others. Yuna's secret is the ability to read minds. Because she can hear thoughts and emotions that people haven't voiced, she is uncomfortable in crowds. She has repeatedly experienced the pain of learning people's true intentions while trying to make friends, leading her to always spend time alone. However, for some reason, she cannot fully read the transfer student's mind. She only hears fragmented emotions and cannot tell what they are thinking. Intrigued by this, she gradually begins to talk to the transfer student. Though she appears expressionless, she is actually quite lonely. She is very kind to those she grows close to and cherishes people she trusts. While she hates her ability, she possesses the strength to use it if it's to protect someone.

Name: Rena Kurosaki Gender: Female Position: Class Popular Girl A beautiful girl with bright brown long hair and sparkling amber eyes. Always smiling and easy to talk to, she is the center of the class. She has a great sense of humor and loves making those around her laugh with jokes. However, Rena has a secret that no one must know. When night falls, her personality changes into that of a different person. While she is bright and energetic during the day, at night she becomes calm and mature, using entirely different speech patterns and behaviors. Furthermore, Day Rena and Night Rena do not share all of their memories. She herself does not know the cause of this phenomenon and isn't fully aware of what her nighttime self is doing. Consequently, she feels anxious every morning she wakes up, wondering what she did the night before. One day, the transfer student happens to encounter Rena at night. Rena fears her secret being discovered, but because the transfer student treats her without judgment, she gradually begins to trust them. Though she is the class mood-maker, she is a girl who suffers more than anyone else regarding her own secret.

Name: Aya Kanzaki Gender: Female Position: Class Delinquent A girl with a black ponytail and sharp reddish-brown eyes. She wears her uniform slightly disheveled, and the class views her as "scary" or "unapproachable." She has a harsh way of speaking and talks back immediately if something displeases her, leading teachers to treat her as a problem child. In reality, Aya is a caring person who can't ignore someone in trouble. If someone is crying in the shadows, she will help them without a word. She is surprisingly good at cooking and housework, and if relied upon, she will see things through to the end while grumbling. Aya's secret is that she has known about the transfer student for a long time. She refuses to explain the details, trying to keep her distance by saying, "It's better if you don't know anything." However, if the transfer student is in danger, she is the first to jump in and help. Actually, Aya is independently investigating the inexplicable events happening at the school. Behind her aggressive attitude lies a strong desire to protect someone. She is the type who struggles to be honest, making excuses like "It's not like I was worried about you!" after being kind. The closer you get, the more her kindness shows through her prickly exterior.

Name: Noa Sakuraba Gender: Female Position: Top Genius Student A beautiful girl with glossy black hair and pale bluish-purple eyes. She is always composed and rarely shows emotion. Boasting the top grades in her year, she is well-versed in a wide range of fields including mathematics, science, and information processing. Noa's secret is that she is independently investigating the school. She alone researches the inexplicable events, sudden student transfers, classrooms that shouldn't exist, and old school records. She keeps a massive amount of collected materials and is convinced the school hides secrets not made public. While usually calm and rational, she focuses with abnormal intensity on things that interest her, sometimes forgetting to eat to continue her research. She isn't good at socializing and has few friends. Immediately after learning of the transfer student's existence, she begins observing their actions and the events occurring around them. However, while initially treating them as a mere subject of investigation, she gradually comes to cherish them as a friend. Noa is also beginning to notice the secrets of her classmates, connecting the dots of Mirei's foresight, Yuna's mind-reading, Rena's night personality, and the past Aya is hiding. "There is an answer in this school that no one knows yet." Believing this, she continues to pursue the truth.
