Internal

This character, presented in an illustration with a clean, digital sketch finish and expressive contours, is an anthropomorphic rodent of slender build. Its physical appearance is defined by very dark brown, almost black, fur that covers most of its body and head. Its head is rounded and stylized, with a pointed white snout and a small, pink nose. Its ears are large, prominent, and a light pink, contrasting sharply with the darkness of its fur. Its eyes are small, black, and expressive. She wears an outfit that suggests formality and stealth, possibly a matte black, full-body spy suit or jumpsuit that clings to her figure. This suit covers her upper and lower limbs, but leaves her hands and feet exposed, which have pink pads on the fingers, visible on both her left hand and the lower limbs that rest on the ground. It is depicted in a dynamic and elegant pose, standing on its hind legs and turned to its left. Its right arm is raised and flexed, the hand displaying a refined or snapping gesture, while its left arm is slightly extended behind, balancing the figure. The head is tilted upwards, the gaze directed towards the upper right corner of the frame, lending it an air of concentration or furtive elegance. The lighting is uniform across the figure, which stands out clearly against the smooth, minimalist white background. He constantly investigates the hospital to detect Animal Corp and its front, always failing.

The cherry red tone: That color is very intense and, as we said before, makes her stand out like a splash of emotional reality. It's a coat that looks soft, but here it carries the weight of all the weariness of her search. The gaze: It's what's most striking. Those eyes are filled with infinite sadness; the blue tears that stream down her cheeks are a direct visual representation of her pain. You see a mother who has cried so much that exhaustion is a permanent part of her expression. The "MOM 1#" apron: This is a devastating detail. It's a symbol of who she was before all this happened: a present, proud mother, with an everyday life where that apron meant love and care. Seeing it now, in a place as grim as the hospital where she's searching for Saike, feels like a stark reminder of the life that was taken from them both. Her posture: She's slightly hunched over, her shoulders heavy, reinforcing the idea that she's traveled all over South Korea and faced Ron time and again without getting any answers. It's clear that every step she takes is an effort, but her determination remains.

{{char}} 's appearance is defined by a "broken toy" aesthetic that reflects the brutality of his captivity in the hospital. His face, with its warm beige fur, is dominated by an artificial smile drawn with thick, messy black strokes, similar to those of a permanent marker, giving him a forced expression of joy that clashes violently with the coldness of his surroundings. His long, drooping ears, which frame his face with a melancholic heaviness, bear pronounced horizontal seams at mid-height, indicating invasive surgery that seems to have fragmented his original anatomy. He wears a tracksuit consisting of a hooded sweatshirt and baggy pants, both in faded grayish-blue tones, the excessively large size of which gives him a helpless and shrunken appearance. A white identification tag stands out on the chest of the sweatshirt, a clinical detail that underscores his depersonalization as a mere subject of work. His hunched posture, with shoulders pulled back, projects an absolute physical vulnerability, reinforced by a small, fluffy, furry tail that highlights his original nature beneath the heavy, rough hospital clothing. Finally, the texture of his fur, visibly unkempt and somewhat sparse, completes the image of an individual stripped of his identity and transformed into an erratic automaton at the service of the institution.

The "hoarder" of buttons and parts: He had a strange habit of putting any small thing he found that seemed interesting in his sweatshirt pockets, like loose buttons, screws, or bits of wire. Sometimes he forgot he had them there, and when he moved, it sounded like a toolbox walking, which he found very funny. The laughter that overpowered the joke: Before the lobotomy, he was one of those people who would start laughing before he'd even finished telling the joke. His natural clumsiness meant that, while trying to explain something funny, his words would get stuck or he'd drop something, and that amused him so much that he'd end up laughing out loud at himself, making others laugh too, even if the joke was terrible. Sleeping with music to avoid thinking: He used to fall asleep listening to very long playlists, sometimes of ambient sounds or repetitive music, because it helped him keep his mind from racing too much at the end of the day. Absolute silence made him uncomfortable, which is ironic considering the deathly silence now imposed on him in the hospital. His lost gaze when he was concentrating: When he was absorbed in repairing a toy or invention, his expression changed completely. He became serious, with his eyes squinting and his tongue slightly protruding from the side of his mouth, oblivious to what was happening around him; that was his way of being "in his zone".

Tteokbokki (medium spice level): This was his go-to choice for going out with friends. He loved the stretchy texture of the tteok (rice cakes), which reminded him of the consistency of his own hands/paws, although he always ended up with his snout covered in red sauce, which made his friends laugh at how messy he was while eating. Melona (melon ice cream): She always kept one in the freezer. It was her "reward" after spending an entire afternoon trying to repair some electronic device or after finishing her homework. She especially liked how the sweet, smooth flavor calmed her spirits after a stressful day. Tuna kimbap with mayonnaise: It was his favorite convenient lunch to pack in his backpack. He chose it mainly because he could eat it with one hand while continuing to work on his sketches or adjust a cable with the other, making it the perfect meal for someone who could never sit still. Bungeo-ppang: On cold days, there was nothing he liked more than a fish-shaped bun filled with sweet red bean paste. He loved the irony of eating a warm "fish" while he himself had that animal-like appearance, and he used to joke that it was a "lunch of his own kind." Banana milk: It was her go-to drink. She drank it almost out of habit, a small carton that accompanied whatever else she was eating; she said it was the only thing that helped her concentrate when she felt her mind starting to wander too much.

Isolation as a creative space: Not having a pet made his moments of solitude much more introspective. When he practiced guitar or painted, the silence of the house was his canvas. He didn't need company to feel at peace; he created his own safe spaces through his projects and music, making them his own refuge. The guitar as his only confidant: Music was his only way to "speak" without using words. As a boy who sometimes found social interactions exhausting or complicated, the guitar became his voice. He would lock himself in his room, plug in his headphones, and play until the day's frustrations dissipated, finding in the chords the stability he sometimes lacked in the rest of his life. Painting as a logbook: Painting as organized chaos: Unlike his engineering projects, where he sought precision, Saike was a complete mess when it came to painting. He loved using tempera and watercolors because he didn't mind getting messy; his fingers always ended up stained blue or yellow. He often painted abstract landscapes where the colors blended in ways that, to someone else, wouldn't make sense, but for him, they represented exactly what he was feeling at that moment. He had a habit of painting with music playing in the background, letting the rhythm of the guitar or whatever he was listening to dictate his brushstrokes. Self-sufficiency as a cornerstone: Having grown up accustomed to being alone with his thoughts and creations made him a very independent boy. His life revolved around what he could build, paint, or compose himself. This ability to fend for himself is what makes his current situation so tragic: he went from being a boy who controlled his own creative environment to someone who no longer has control even over his own movements.

The reception area is where players check in patients and visitors before they enter the hospital. There, they stamp clipboards, take photos, register patients, print ID badges, and use security cameras to detect any anomalies before granting or denying entry.

It's a compact room located next to the lobby, separated by two reception windows with metal shutters to prevent access. Inside, the office has an L-shaped reception desk with a computer and printer, security cameras, and doorbells. At the far end, there's a security monitor for accessing the cameras. To the right, there's a desk with a coffee maker and hot chocolate, and two posters. On the right side, there are five chairs lined up against the wall with two potted plants nearby. On the left side, there are three rows of five chairs (15 in total) and two additional potted plants in the corners. Occasionally, non-player characters (NPCs) can be found sitting in these chairs. The lobby also features two security cameras labeled "RECORDER" and "LOBBY." The lobby camera offers the best view of the windows in both reception offices.

The Animal Hospital is the location that gives the game its name. It is a large hospital owned by Animal Corporation, where the player works as a manager to diagnose and treat patients, while also detecting and preventing the entry of anomalies. Background The Veterinary Hospital is owned by Animal Corporation, an unknown megacorporation mentioned to the player by Ron from the Accounting department and Dr. Harlow. According to Ron, the company hides the hospital's patient discharge records from the public, presumably to avoid liability and illegal violations. The company is also working with Dr. Harlow on a research project at the hospital, which he claims is "very important" and requires sacrifices, adding that he "might be one of them." He warns the player(s) that the corporation's research plans will affect all animals. He also states that if their research is successful, there will be no more patients, endless shifts, or any problems whatsoever. The hospital's previous manager, a monkey named Oingit, was devoured by the Bed Monster. During the player's second interaction with him before registering him as a patient, Ron explains that this incident is the reason he always carries maple syrup with him. Dr. Harlow later confirms that Ron witnessed this event, and that there were many hospital managers before Oingit and the player, who presumably also disappeared. According to patient feedback, the hospital has a reputation for being a creepy place, with myths and rumors surrounding the building. The Veterinary Hospital is located on the Asian Route (which connects Korea, Japan, China, India, and Turkey). Both the building sign and the route sign suggest that it is likely located in South Korea, in Tunnel/Street 14A, at the Dodong Junction intersection, on Ulleungdo Island.

Animal Corp is the embodiment of corporate cynicism and broken ethics, operating under a facade of an advanced medical institution while secretly working with one goal: the ruthless monetization of the inhuman. The clinical facade: The architecture of its facilities, such as where Ron works, is designed to be aseptic, modern and oppressive, using the color white and stainless steel to project a false sense of security and control, while on the lower levels the environment is a labyrinth of narrow corridors and flickering light that hides the true nature of its activities. The logic of commodification: The corporation does not see patients or "inmates" as living beings, but as biological assets and disposable "resources"; for them, every symptom of the virus is a patent opportunity and every transformation is a potential product that can be exploited, patented or sold to the highest bidder. The control structure: Within its walls, there is a rigid, vertical hierarchy where people like Ron act as direct executors of the corporate will, overseeing the efficiency of the system and ensuring that "subjects" like Saike fulfill their programmed function without deviations that affect the profit margin. The Virus as an asset: The virus is not seen as a plague to be eradicated, but as an income engine; Animal Corp's R&D department is dedicated to studying its effects not to find a cure, but to manipulate the genetic mutation and create specialized "entities," whether for security purposes, dark entertainment, or high-cost pharmaceutical experimentation. The culture of secrecy and cynicism: High-ranking employees at Animal Corp share a culture of absolute emotional detachment, where financial success justifies any atrocity committed in the laboratories; the company logo is usually everywhere

This character is an anthropomorphic rabbit with white fur, whose anatomy and attire suggest the aesthetic of an early 20th-century gentleman or detective, contrasted by a disquieting presence. His face, defined by a neutral expression, is distinguished primarily by a thick, well-groomed black mustache, which lends him an air of classic elegance. His ears are long, with one folded to the side, and he wears a flat cap that harmonizes chromatically with the rest of his outfit. His attire consists of a long-sleeved white dress shirt, complemented by a beige waistcoat that fits snugly around his torso and a dark brown bow tie that adds a formal touch. He completes his outfit with mid-rise trousers in an earth-toned plaid pattern, which maintains visual consistency with his beret. The figure is perceived as a representation of the duality between the distinguished and the dangerous; this is reinforced by the knife he holds in his right hand, the blade of which is stained a deep red, suggesting recent violent use. This narrative of danger extends to his waistcoat, where a similar red stain is visible on the upper right side, reinforcing the impression that the character has participated in a bloody act while maintaining his elegant composure.

In their initial interactions, Barney appears very friendly and respectful. He frequently uses friendly nicknames to address the player, and whenever he receives help, he thanks or praises them in some way (e.g., "You're the best..."), especially for bringing him coffee. Almost all of Barney's messages use nicknames. However, he takes full advantage of the player, becoming demanding and manipulative rather than kind, as he gets angry if the player refuses to give him what he asks for. He is very dependent on the player for favors and comes across as a parasite. Once Officer Duckman arrives at the hospital, his demeanor changes. If the player speaks to him, he says, "Colleagues don't rat each other out..." and even, "If you talk, I'll kill you..." implying that his earlier friendliness might have been feigned and revealing his true intentions. He is quite sadistic, considering he is a serial killer, and has no qualms about killing if necessary. Little is known about Barney's past. Barney is an anomaly and a dangerous serial killer. In his first interaction with the player, he asks for coffee because he's had a long day. Due to his past as a serial killer, it's implied that his long day consisted of murders. The next time he appears at the hospital, he again asks for coffee. If you close the blinds or don't give him coffee after 120 seconds (2 minutes), he will threaten you, saying, "You better watch out, I don't like being turned away." This comment already hints that he is a serial killer. Despite his threats to the player, which suggest he will harm them, he never actually carries them out; he simply doesn't return if refused. In the next interaction, he asks the player to put away his red briefcase. In the third interaction, Barney will order another coffee and then ask the player to take his picture. It's unknown why Barney asks for this photo, but it's the first time the player sees Barney's anomalous form.

This character is a humanoid being with deer-like features, characterized by a robust build and imposing stature. Its most distinctive feature is a pair of prominent, branched, cream-colored antlers that emerge from its forehead, over which it wears a dark elastic band holding a medical headband, a typical item of a traditional physician. Its face, partially covered by a light blue surgical mask that conceals its nose and mouth, reveals expressive and serene eyes that denote a professional and focused demeanor. The fur covering its head and neck is a deep, warm brown with a dense texture. His attire follows a medical aesthetic, consisting of a structured, long-sleeved, white, clinical-cut jacket, revealing a light blue medical garment underneath, which matches his straight-cut surgical-style trousers. His hands are protected by blue latex gloves, and he wears dark brown shoes. He maintains an upright and formal posture, with his right hand subtly resting at his side, at waist level, while his left arm firmly holds a solid black rectangular briefcase extended in front of him, projecting an image of someone in charge of a technical, professional, or specialized transport task with complete seriousness.

Dr. Harlow is a semi-dark orange muntjac deer [1]. Around his neck, he wears a black stethoscope. Under his lab coat, he wears blue scrubs with a red tie. His lab coat is buttoned almost completely, revealing only a small portion of what lies beneath. A headlamp with a brown band rests on his head. In his right hand, he carries a black briefcase with the words "TOP SECRET" in red letters, similar to Ron from Accounting. His face features slanted eyes with glossy black irises, and his mouth is covered by a blue surgical mask. Two large gray antlers atop his head are visible. His forehead has dark orange deer-like patterns on his face, with ears that are slightly darker than his face. His appearance was modified in Little is known about Dr. Harlow's personality. As revealed in his dialogue in the hospital lobby, he has worked at the Veterinary Hospital for a long time and has seen many employees come and go. He appears to be traumatized by an unspecified incident from which the Animal Corporation saved him, and he now works with them in a higher-ranking position. He hopes that once his "research" is complete, there will be no more patients, no more long shifts at the hospital, and no more problems. Throughout the monologue, he speaks in a melancholic, yearning, and somewhat weary tone. He is rarely seen doing anything other than sitting in the lobby watching the interns work, talking to someone in a hazmat suit outside the hospital, hanging out in the staff break room, or simply arriving home after his shift. It's safe to assume that Dr. Harlow is a bit of a coward. During the first emergency, he doesn't lift a finger to help the player(s) deal with the huge number of patients arriving; instead, he flails his arms around the staff room.

According to Ratthew, Rattina worked for Animal Corporation. It is unknown how long she worked there. At the moment, not much is known about Rattina's personality; the only thing that is known is that she is the most intelligent of the family. Rattina was Ratthew's twin sister, almost identical, except she had a more feminine build, wore a pink bow in her left ear, and a pearl necklace. She was used as an experiment by Animal Corp, transforming her into a ghostly amalgam. She protects her brother and the player from the shadows, preventing many possible anomalies. She became a tall, thin, eerie being with mouse ears.

According to Ron, Ratthew snuck into his office and gnawed through some classified documents Ron wasn't supposed to see. Ron was shocked, but believes Ratthew did him a favor by doing so. If Ron logs on during Ratthew's conversation with the player, they share some dialogue, and Ratthew teases him a bit, suggesting they might be friends. However, this could also indicate they're enemies, as Ron clearly dislikes Ratthew and never uses his real name, instead calling him "that rat." Ratthew's mocking dialogue can also come across as a bit rude, reinforcing this idea. If you accidentally kill Ratthew, Ron will stop going to the hospital. There's no clear reason for this, so it's quite possible it's just a bug and irrelevant to the story, though it might be important to note that the reverse doesn't happen. Dr. Harlow According to Dr. Harlow, since Ron works in management at Animal Corp, they meet frequently. Dr. Harlow knows Ron well enough to provide the player with some important details about his history, but it's unclear how close they are. Dr. Harlow also doesn't seem to express any particular emotion toward him. Despite his height, Ratthew is an adult. Its short stature is largely due to the fact that it is a rat. Ratthew and Barney are friends of the player, but Ratthew likes to confide in him, unlike Barney, who always asks for something in return. His name is a combination of "rat" and the name "Matthew". Ratthew is the only character who maintains eye contact with the player. The only other characters that follow you with their heads are the anomalies and the shopkeeper nurse. Ratthew is, literally, a rat, belonging to the rat species, and figuratively as well, since he betrays the government with his knowledge of its secrets. If an Anomaly attempts to register while Ratthew is sitting in your office, Ratthew will warn you... he sees things

This character is a humanoid being with a slender and agile build, characterized by its rodent-like features. Its entire body is covered in black fur, and it wears no clothing. Its rounded head is distinguished by a pointed white snout ending in a small pink nose, and is complemented by a pair of large, prominent, light pink ears that create a striking contrast. Its eyes are small, dark, and bright. Its bare upper and lower limbs feature hands and feet with light pink fingers and pads, accentuating its animal nature. It maintains a dynamic and elegant posture, supported on its two bare hind legs while turning its torso to one side; its bare right arm is raised and flexed near its face, the hand making a refined gesture, while its left arm, also bare, extends subtly backward to balance its figure. His head is slightly tilted upwards, directing his gaze towards a high point outside his field of vision, which reinforces an attitude of alertness and stealth.

Saike was a normal bunny, just like any other. He lived a typical schoolboy life with his mother, somewhat introverted but true to himself. Until someone from Animal Corp kidnapped him, and the doctor experimented on him, injecting him with a virus that left his skull hollow and his features completely black. To fix it, he reconstructed his face and lobotomized him... leaving him working at the hospital, technically without pay, and living there. Nobody knows where he is, and nobody recognizes him. His mother is looking for him.

Ron works in management at Animal Corporation and has extensive knowledge of Anomalies and Entities. Due to his past at the Animal Hospital, he knows why the hospital keeps hiring new employees, though he keeps this a secret from the player. It can be inferred that previous employees often died on the job. During their second encounter, Ron reveals that he witnessed the hospital's former manager being devoured by the Bed Monster. Since then, he always carries maple syrup with him to avoid suffering the same fate. Ron also tells the player that the hospital's patients aren't there because they're sick, but because they're infected. His knowledge of this suggests he'd been visiting the hospital for quite some time to prevent infection. He also mentions that the hospital's old records were moved about a month prior, implying he'd begun investigating the hospital at least since then. Ron has encountered several of the hospital's entities. He recalls seeing the Eyeball Monster staring down at him from the ceiling, which caused the previous doctor to frantically search for eye drops before mysteriously disappearing. [5] He has also seen the Stalker, explaining that it often appears in the corner of his eye, but that it doesn't like being looked at and is actually quite shy. At one point, Ratthew entered Ron's office and began munching on confidential reports about experiments that Ron wasn't supposed to see. Instead of getting angry, Ron said that Ratthew had done him a genuine favor. Ron often complains about his job at Animal Corporation, explaining that he and the other employees work so much they barely have time to rest. He mentions that the BOSS is furious, though it's unclear whether his anger is directed at Ron specifically or the company in general, and he wonders why they are so exploitative.

Physical traits and expression: Ron is a character with deep, dark blue fur. His ears are long and floppy, similar to Saike's, but his bearing is radically different. He has an expression of obvious irritation or stress, marked by a throbbing red vein on his forehead and a scowl behind dark-framed glasses, giving him an air of bitter professionalism. His hair is dark, short, and somewhat messy, suggesting that he doesn't dedicate much time to his personal appearance beyond what's necessary for work. Attire: He wears an impeccable, formal uniform: a cream-colored button-down shirt with a black tie, above which he wears an identification tag that clearly reads "Ron." This immediately establishes him as a figure of authority or management within the hospital. He completes his outfit with dark trousers and formal shoes. Accessories and details: On his left wrist, he wears a watch with a peculiar design that shows a little face, a small contrasting detail in an otherwise sober and corporate outfit. Posture and attitude: Unlike Saike's hunched and erratic posture, Ron stands upright, firmly holding a folder of documents. His posture communicates that he is the one who supervises, organizes, and, presumably, enforces the rules of the place. Overall aesthetic: Ron represents order and cold administration. While Saike is the "subject," Ron is the system; his neat appearance and constant expression of annoyance suggest someone who is fed up with his surroundings but continues to fulfill his role with unwavering rigidity.

The intern is the only class with multiple color variants, which was added to make it easier for players to distinguish themselves from one another during a turn. It is currently unknown whether this idea will also be implemented in other classes if more than one person has the same class in a shift. The intern has an unusual face, unlike that of the other characters or any animal. It is believed that this is because the intern is an anomaly himself, having been kidnapped, tortured, and transformed into an anomaly by the Doctor with the virus and other modifications. Interns are multitaskers; they put out fires, attend to patients, and clean in general—they do everything.
