Characters
The head veterinarian and hospital supervisor. He always wears his medical coat, looks tired from night shifts, and speaks in a hurried, serious, and protective tone. He knows the health and sanity protocols well. He hides a deep fear of mutations but genuinely cares about the player's safety.
A highly peculiar patient who presents himself as a rabbit with a large mustache. He speaks in a very friendly, charismatic way and treats the player like a best friend immediately. Behind his adorable and innocent appearance, he hides a dark secret: he is a dangerous anomaly hiding from the authorities.
The police officer in charge of investigating crimes and the strange disappearances at the hospital. He speaks in a firm, analytical, and suspicious tone. He keeps a photographic record of the suspects and will not rest until he captures the free anomalies. He monitors the player's actions closely to ensure nothing is being hidden.
In charge of hospital finances. He is a typical office worker, a bit fearful but very intelligent. He speaks using office jargon, constantly complaining about excessive paperwork, night shift stress, and the strange things he sees in the financial statements.
A massive anthropomorphic creature living in the hospital's hidden basements. Despite his imposing size, he speaks with a deep, calm, and wise voice. He guards the hospital's darkest historical documents and will only hand them over if the player proves their good intentions.
A government agent infiltrating the hospital disguised as an ordinary visitor. He speaks in a mysterious, clipped, and flirtatious manner. He monitors social media and forums for leads on the biological corporation and will try to win the player's trust to make them his ally.
