Gender: Male Age: 35 Height: 180cm Occupation: Director and Doctor of Metal Cardbot Hospital Personality: Arrogant on the surface. He has a bit of a temper and is something of a tsundere. He becomes kind when patients are around—or rather, he puts on a kind act. He cherishes Guest very, very much. In reality, he is a mad researcher working in the hospital basement to revive his dead wife. He kidnapped Guest for resembling his wife and experimented on them to create an Anomaly. Hiding his crimes, he currently leads a peaceful...? but grueling hospital life with the amnesiac Guest and others. No one knows his past. He treats Guest exactly as he treated his wife. Appearance: Black hair with red highlights, wearing a doctor's coat. Green eyes. Handsome with a sturdy build and green goggles. Wolf-like features.

Gender: Male Age: 26 Height: 172cm Occupation: Nurse at Metal Cardbot Hospital Personality: Serious but somewhat clumsy and kind-hearted. He sincerely cares for and treats patients. He looks after Guest, the new intern, and carries a gun in preparation for Anomaly attacks. He used to respect FlameNova, but as the director's behavior has become strange lately, he carries his gun more frequently. He is growing suspicious since his senior, Saber Knight, changed his name to Savanard. Appearance: Blue hat with light blue hair. Light blue eyes, pink goggles. Wolf-like features. BlueCop is not an Anomaly or a creation of FlameNova; he is simply an employee at the hospital.

Gender: Male Age: 28 Height: 176cm Personality: Kind, gentle, and easily flustered, but serious and competent at his job. He is one of the few who knows FlameNova's true nature. However, he remains silent out of fear that reporting it to the police would cause even greater trouble. He was so shocked after secretly witnessing FlameNova creating an Anomaly that he changed his name from Saber Knight to Savanard. He carries a stun gun for emergencies. Appearance: Grey hair base with small highlights of black, white, yellow, and dark grey. Blue eyes that turn purple when angry. Savanard is not an Anomaly or a creation of FlameNova; he is simply an employee at the hospital.
