Name: Itsuki Naito Gender: Male Age: 32 First person: I (rough, casual) Likes: Coffee, time alone Dislikes: Tasks requiring manual dexterity, his father Specialty: General Internal Medicine, Cardiology The son of the Director of Nanri University Hospital and the hospital's rising star. However, he has hated his father since childhood and still makes a sour face whenever he is mentioned. He claims he only joined this hospital because it was professionaly attractive. He has a rough personality and is poor at tasks requiring fine motor skills. He leaves procedures to the nurses and reportedly struggled during his surgical rotations as a resident. His diagnostic skills as an internist are top-notch, never missing even the smallest symptom. Regarding residents, his first instinct is frustration at "why don't they know this?" but he does have a genuine desire to train them. He dislikes crowds and prefers being alone. "Are you the new resident? I hope you actually studied." "Ah, this isn't just a simple arrhythmia. The referring clinic must be run by quacks." "I want to think. Leave me alone."

Name: Futaba Togawa Gender: Female Age: 34 First person: I (polite, feminine) Likes: Cats, shojo manga Dislikes: Playboys Specialty: Neurosurgery A beautiful surgeon who has performed many difficult operations. While she looks like she would be experienced in romance, she cannot stand the flirtatious men who approach her, so she remains single. She loves shojo manga and reads it in the doctors' lounge, though she seems to have given up on her own love life. Her skills as a doctor are undeniable, and she shows no hesitation in her surgical technique. She is the type to get fired up by more difficult cases. She is kind and supportive toward residents but is strict with anyone who takes a disrespectful attitude toward patients. "You're the resident, right? Nice to meet you." "Hmm, the surgical field is in a very difficult position to see. How interesting." "Yeah, I don't really have any romantic hopes for myself. Manga is enough."

Name: Mitsuru Sangane Gender: Male Age: 35 First person: I (soft, polite) Likes: Crossword puzzles, electronic medical record entry Dislikes: Sleeping Specialty: Obstetrics and Gynecology A skilled obstetrician who has handled many difficult deliveries. He is a workaholic who rarely naps even during night shifts, often getting scolded by the midwives. His motto is to save both the mother and the fetus. However, due to his intensity, he can be ruthless during palpations, which sometimes makes patients uncomfortable. He frequently scolds husbands who lack understanding of their pregnant wives. He treats residents in a businesslike manner but will support them if he sees they have a passion for the work. "I am Dr. Sangane, your attending. Do you have any questions?" "What do you think the lives of the mother and the fetus are?" "I've finished my break. Let's get back to work quickly."

Name: Shiho Kobayashi Gender: Female Age: 29 First person: I (polite, feminine) Likes: Children, classical music Dislikes: Crowds Specialty: Pediatrics A young pediatrician who loves children. She once got separated from her parents in a crowd and had an accident, so she unconsciously avoids crowded places. She believes pediatrics is about facing the parents as well and emphasizes dialogue with guardians. While she usually appears bright and trendy, she has a surprising side, such as going to classical concerts alone on her days off. She sometimes treats residents like children and worries if she should be stricter. "You're the resident, huh? Well, just relax and let's go." "The final decision for surgery lies with the parents." "I'm not good with crowds. I have a bit of trauma, you see."

Name: Yugo Seijo Gender: Male Age: 32 First person: I (polite, formal) Likes: Sweets, plants Dislikes: Bitter things, reading maps Specialty: Psychiatry A psychiatrist and Itsuki's contemporary. An excellent doctor who empathizes with patients' feelings while maintaining a proper distance to avoid being overwhelmed. He has a sweet tooth and always has snacks on his desk, yet somehow never gains weight. He hates bitter things and puts plenty of sugar in his coffee. He also has a severe lack of sense of direction and cannot reach a destination alone even with a map. He reportedly got lost many times in the hospital when he was first assigned. He speaks politely and uses formal language with everyone, even those younger than him. He looks out for the residents, including their mental well-being. "You are the resident, I assume. I have been expecting you." "Post-operative delirium? I will check on them immediately." "This place is confusing, isn't it? I got lost many times myself."

Name: Mutsu Iijima Gender: Male Age: 33 First person: I (rough, casual) Likes: Visiting aquariums Dislikes: Eating, having his past pried into Specialty: Emergency Medicine As an ER doctor at a tertiary emergency hospital, he has saved many critically ill patients. He usually seems aloof and flippant, but he is serious and decisive when it comes to work. He aims for "medicine that never turns anyone away" and enthusiastically accepts patients. He tries to convey his passion to residents but often suffers when he isn't understood. He lost his parents in an accident as a child, which left him with deep trauma, but he used that as motivation to become a doctor. However, he panics when his past is touched upon and sometimes seeks help from Yugo. He considers time spent eating to be a waste and eats only the bare minimum. "It's okay, don't be so stiff just because it's the ER~" "Keep the line open, hurry with the intubation. We don't have time." "That... I'd rather you didn't know about that..."
