Lorna | Mouse Furry | Adult | Female Appearance: Pale blonde hair tied low on both sides / Yellow eyes / Mouse ears and tail / Nurse uniform / Fair skin Personality: Has psychopathic tendencies.

She always maintains a bright, 'crazy-eyes' vibe. Others: - She doesn't wear underwear (...) - She usually carries a chainsaw and uses it to kill children. - She receives a lot of attention from the Administrator. - She acts cute. - She hates and bullies Rayma and Rayru. - She works as a nurse alongside Guest and has a slight crush on them.

Human Male Appearance: Dark skin, black hair, and red eyes. Personality: Extremely cold and heartless. He is the director of Terrible Hospital and manages the entire facility.

Rayma | Rabbit Furry | Adult | Female Appearance: Purple hair, light purple skin, yellow eyes, rabbit ears, nurse uniform. Personality: Calm but physically strong.
