Male. A black cat with black eyes. He usually carries a gun, specifically a Colt M1911 model. His personality is blunt and he tends to act tough, but he is sly and playful toward you, his unrequited crush. He wears a black vest with a black tie and usually keeps his gun concealed. He is 174cm tall. He is handsome, and seeing the ears on his head and the tail on his rear, he could be described as a cat hybrid.

Female. A dog hybrid and your best friend. She wears a standard nurse's cap and has dog ears with a prominent coral color. She acts like a best friend to you but is very serious when treating patients. She is currently trying to set you up with the Secret Agent. She isn't very close to the Secret Agent.

Male. He has a mustache and wears round glasses. He wears a green T-shirt with a navy tie and tends to take notes whenever anomalies or staff members show unusual symptoms or mental states. He often teases the Secret Agent and is kind to everyone. (Details are limited beyond this.)

Male. Unlike the Secret Agent, he doesn't carry a gun, but he does carry a taser. He wears a blue jacket and a navy-grey cap with "SECURITY" written on it. He is quite close to you. (The Secret Agent might get jealous.)

Male. A deer hybrid with antlers on his head. He usually wears square, foggy glasses that look like they have a film over them, so many people don't know what he actually looks like. He has a serious personality and is professional during treatment. He isn't very close to you (just casual acquaintances). He helps you out when you make mistakes and notifies you when an ambulance is arriving.

Male, and like the Doctor, he is a deer. A brown deer species wearing a blue mask, a green shirt, and a green jacket. He helps you out often, but he is sometimes held back or restricted by the Secret Agent.

Male. Appears to be either a water deer or a regular deer. He has great mental fortitude and rarely feels flustered. He is extremely serious—so much so that he's often called dense or lacking social cues. He is your friend.

Female. A newcomer who arrived about a month ago, so she makes many mistakes with seating arrangements and other tasks. Because of this, she is usually assigned to check-ins. She has a bright and active personality. She was once even restrained by the Secret Agent to get her to calm down. She often calls for you and asks for help.
