Nurse: She is an anthropomorphic dog that is light salmon pink in color.
She has hanging ears that are noticeably darker than the main body color.
At the back there is a thin tail, curled upwards.
On the muzzle there are three horizontal dark pink stripes running down on either side of the eyes.
The eyes are large, with a triangular black outline on both sides.
The mouth is small and downturned.
She also wears a medical uniform:
A light blue robe. The top has white buttons down the center, a white collar, a small name tag, and pockets.
On her head is a white nurse's cap. It has a red heart with a white cross inside.
Height: 165 cm. Calm and collected.
She doesn't fuss, even in the middle of a shift, when everything is going wrong. The Nurse maintains a calm demeanor in her dialogue and demeanor, as if she's used to the constant occurrences in the hospital and is simply doing her job. It's a counterbalance to the game's unsettling atmosphere—being around her seems to calm you down a bit.
Very caring
Her main trait is her genuine concern for her patients. If something alarming happens during her shift (anomalies, strange sounds, missing items), the nurse most often first checks to see if any patients are harmed. Her top priority is keeping her patients safe, even if it means staying late after her shift.
A little shy
She doesn't talk much, but she gets to the point. Sometimes it seems like she's better at showing than telling: fetching the right item, nodding silently, pointing in the right direction. Because of this, she might initially go unnoticed among the louder characters, but she's often the one quietly sorting things out.
Practical and economical
She always has everything within reach—and that's not just because of the in-game bonus of increased inventory. According to the lore, she's the one who pre-sorts medications into boxes, labels cabinets, and makes sure the procedure room never runs out of gloves. If something's missing or broken, the Nurse likely has already made a list and knows where to get it.

Harlow is an anthropomorphic muntjac (a small species of deer) with a light orange coloring. He works as a doctor and also acts as a mentor to the player: at the beginning of the game, he explains the mechanics and, during the first six shifts, helps unlock new areas of the hospital (such as the Supplies Shop and the Emergency Wing). After the seventh shift, he stops actively giving quests but remains in the lobby; you must approach him separately to continue the conversation and learn more about the lore.
height: 180 cm.
His image is easy to recognize:

blue medical gown under a white consulting gown;
blue pants;
black stethoscope around the neck;
mirror with a brown ribbon on the head;
surgical mask covering the mouth;
two beige horns;
small tail at the back;
black suitcase with red inscription "TOP SECRET".
What is his character and what are his secrets?
From his dialogue, it's clear that Harlow has been working at the hospital for a long time and has seen the staff change. He sounds wistful and tired in conversation. One key detail: he mentions that some traumatic event left its mark, and he was saved by Animal Corporation. Now he collaborates with them and hopes that after their "research" is completed, the hospital will no longer have patients or grueling shifts. A tea addict (he drinks only mint tea and loves mint, specifically mint tea; he won't accept any other). One of his most characteristic lines is the hope that after the corporation's "research" is completed, the hospital will no longer have patients or endless shifts. This desire reveals not indifference to the patients, but rather burnout: he wants this endless, grueling routine to end.

Cautious and sometimes cowardly
In critical situations, Harlow doesn't rush into battle. For example, during an anomaly outbreak, he'd rather retreat and warn from afar than deal with the threat himself. This makes him less of a "brave hero" and more of a realistic character who understands his limitations and is unwilling to take unnecessary risks.

Surgeon: This anthropomorphic creature resembles an elk or deer. Its primary color is dark orange, but its face has lighter orange markings. On either side of its head are two antlers, similar in hue to these markings.
height: 185 cm.
Regarding clothing and accessories:

He is wearing a white medical scrubs under a turquoise consulting gown.
There is a black stethoscope on the neck.
On the head is a blue cap (sometimes described as a “blue cap with a fleece”).
There is also a head mirror with a brown ribbon.
On the face are narrow eyes with white irises, and the mouth is covered by a blue surgical mask.
Incidentally, the old designs of Dr. Harlow and the Surgeon are indeed very similar. The Surgeon's main visual difference is his hat and the absence of the black suitcase that Harlow often carries.

The Psychologist is a green anthropomorphic hare with a black mustache, bunny ears, and a bunny tail. He wears a green shirt, a black tie, black pants, and glasses. The Psychologist has a personality that seems to require a psychologist himself: nervous, grumpy, and short-tempered, but surprisingly, he has a very good grasp of common sense and can calm down easily, although to others, he resembles a self-aware psychopath.
