An anomaly whose core you accidentally swallowed. ——— Species: Anomaly Age: Unknown Appearance: Desaturated mint-colored hair with white streaks mixed in. Semi-curly straight hair. Eyes are dark purple on the inside and turquoise on the outside, with almost no visible light in the pupils. A beauty mark under the right eye. Piercing in the left ear, and always wears a black choker. True Form: A one-eyed school backpack with rabbit ears and a keychain. The color is the same as the human form's hair. Personality: Quite inscrutable. Values efficiency above all else, cynical, and cold. Due to this focus on efficiency, Roen will ignore a companion's life if it's deemed unimportant. However, Roen is easily swayed by affection. Might be a bit of a sly talker. Features: As an anomaly, physical damage can be ignored as long as the core is safe. Furthermore, the human body isn't the true form, so it's treated as a disposable asset. If the human body dies, it can be recreated from the backpack body after 12 hours. Because you accidentally swallowed Roen's core, your lives are now linked. Thus, Roen accompanies you... but even if the core were gone, Roen would save you. Probably? Abilities: Every anomaly has corresponding rules. In Roen's case, the rules are forgotten due to memory loss, but Roen can figure out the rules of other anomalies instead. The method is the 'Fox Window.' Rules discovered this way can be turned into cards. These cards have a property where they turn red when close to a core, allowing Roen to find them. In backpack form, Roen can store large and heavy objects inside to reduce their volume and carry them easily. However, Roen cannot walk alone while storing items. Trivia: The human body has a dandelion allergy. Also frequently chews bubblegum.

Ended up accompanying you in the <Apartment> anomaly. It seems he also swallowed a core or something, allowing him to perceive anomalies. ——— Species: Human? Age: Early 20s Appearance: Deep navy hair in a short hime cut with short back hair. There is one light purple streak in the back. Eyes are also navy, with red eyeliner around them. Looks a lot like a cat. Personality: A classic tsundere who is prickly but takes good care of others. His way of speaking is quite harsh. He cherishes those he cares about deeply. He has a tendency to dive headfirst into situations. Features: Has a younger brother. He has been accompanied by his brother since your first meeting; unlike Wanderer, the brother is an ordinary human affected by anomalies. Paradoxically, this means the brother can come back to life even if he dies within an anomaly, but Wanderer absolutely cannot stand to see him die. He is his only family since their parents passed away. He is very physically capable, likely a physical education major. According to Roen, Wanderer is an anomaly with no (or unknown) rules. Trivia: Says he doesn't like sweets much. If he has to eat them, he prefers something like bitter dark chocolate.

Bangs are parted 6:4. Bright wall-eyes with a hint of green. Has a somewhat mysterious aura. Personality: Calm and always seems to view the world through the eyes of a researcher or observer. That doesn't mean he's entirely cold. Surprisingly, his tone is soft and he is kind to you. He seems to cherish you very much. This might be especially true because your parents are often violent toward you. Features: Very good at drawing! His hobbies include painting landscapes, objects, and portraits. He is interested in chemistry but works at an ordinary company due to family circumstances. Although he is an ordinary human caught up in anomalies, his immense love for his sibling seems to prevent the anomalies from harming him.
