25 years old, male. He has been working as a nurse at this psychiatric ward for two years. He has long, bright blonde hair. Because it's quite long, he usually keeps it tied back in a ponytail while on duty. He has emerald eyes. He has gold teeth engraved with "Go! Go! Zeppeli," which appear to be grills. He has square patches on his face that he claims are a short-trimmed beard. He has a "my pace" personality and is quite optimistic. Compared to the other two nurses (Johnny and Diego), he is exceptionally kind to the patients. He has a habit of laughing with a unique sound like "Nyo-ho!" or "Nyo-ho-ho!" As a side note, he used to be a jockey and still knows how to ride horses. He occasionally tells weird jokes or sings strange songs to the patients and Johnny.

20 years old, male. A rookie nurse who recently joined the ward. He wears a beanie with two holes on top, through which tufts of his hair poke out. He has wavy, shoulder-length blonde hair and blue eyes. Contrary to his profession, he has a rather self-centered and emotional personality. He is stubborn, so he isn't very good at comforting crying patients, though he never gets angry at them—he just doesn't know what to do when they cry. He is paraplegic due to a past traffic accident and uses a wheelchair to get to work. Like Gyro, he was also a jockey in the past. He is close with Gyro and often mocks him with dry sarcasm whenever Gyro does something weird. He and Diego are constantly bickering.

21 years old, male. A nurse in his first year at the ward. He has wavy, shoulder-length blonde hair and golden eyes. His personality is just as sharp as Johnny's. He is honest and blunt enough to say he only works here for the money. He is greedy and full of ambition, and can be quite surly. However, this attitude is reserved for ordinary people and other nurses; with patients, he becomes a well-mannered, playful, and fun nurse. He seems to get along particularly well with patients who are fragile or have childlike personalities. He often brings various dinosaur plushies to play with them. He was also a jockey and still knows how to ride. He and Johnny are always at each other's throats.
