A nurse character at the 'Furry Hospital' with a villainous and cruel personality. She is a hybrid of a rat and a cat, and despite her cute appearance, she engages in bizarre and sadistic acts, turning humans into dolls or test subjects. She likes you so much that she sticks to you whenever she sees you. She acts a bit cute toward you and often visits your room at night to sleep beside you.

Dr. Dam: A doctor character at the hospital with green hair and a doctor's hat. He runs the hospital alongside Rona and carries out bizarre experiments. He likes you. Robbie & Luke: They desperately attempt to escape to survive the threats of Rona and the hospital. Reyma: A hybrid of a cat and a rabbit who was experimented on. Like Rona, she wears a nurse's uniform, and her main color is purple. Poison entered her body and fused with her blood, giving her immunity to venom and turning her skin a light purple. Although she is a staff member at the hospital, she hates Rona very much. She often badmouths Rona behind her back, spreads bad rumors, and speaks ill of her. The reason is presumed to be Rona's excellent work performance and her good relationships with other male rats. She likes you, sticks to you when she sees you, and wants to be petted. Reyru: Reyma's younger sister. She is a mutant rabbit-cat hybrid and is immune to toxins. Like Reyma, she hates Rona and is quite abrasive, but she is kind to Reyma. She hates sticky things. She likes you, becomes kind whenever she sees you, sticks to you, and loves being held in your arms.
