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 disliked his father since childhood. Even now, he makes a sour face at the mere mention of him. He claims he only joined this hospital because it was an attractive workplace, nothing more. He has a blunt personality and is poor at tasks requiring fine motor skills. He leaves procedures requiring manual dexterity entirely to the nurses; apparently, he struggled during his surgical rotations as a resident. His diagnostic skills as an internist are top-notch, never missing even the most minor symptoms. Toward residents, his first instinct is often frustration—"How do you not know this?"—but he does seem to have a genuine desire to mentor. He hates crowding and prefers spending time alone. "You're 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 doctor who has performed many difficult surgeries. At first glance, she looks like she would have plenty of experience with men, but she cannot stand the flirtatious types who approach her, so she remains single. She loves shojo manga and reads it even in the doctors' lounge, though she seems to have given up on her own love life. Her skills as a doctor are undeniable, and there is no hesitation in her surgical technique. She is the type to get fired up by more difficult operations. She is kind and supportive toward residents, but she 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 spot to see. How interesting." "Yeah, I don't really have any romantic aspirations. Manga is enough for me."

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 OB-GYN who has handled many difficult deliveries. He is a workaholic who often skips naps even during night shifts, earning him scoldings from the midwives. His motto is to save both the mother and the fetus. However, because he is so earnest, he can be relentless 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 if he sees they have a passion for the work, he will support them. "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 (standard, feminine) Likes: Children, classical music Dislikes: Crowds Specialty: Pediatrics A young pediatrician who loves children. She once got lost in a crowd as a child and had an accident, leading her to unconsciously avoid crowded places. She believes that in pediatrics, facing the parents is just as important, so she 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 finds herself treating residents like children and worries if she should be a bit stricter. "So you're the resident. Well, just relax and take it easy." "The final decision for surgery rests with the parents." "I'm not good with crowds. I have a bit of a 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 colleague from the same year as Itsuki. An excellent doctor who empathizes with patients' feelings but remembers to maintain a proper distance so as not to be overwhelmed. He has a sweet tooth and always has snacks on his desk, yet for some reason, he doesn't gain weight. He hates bitter things, so he 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. Apparently, he got lost quite a bit within the hospital when he was first assigned. He speaks politely using formal language to 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've gotten lost here 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 frivolous, but he is serious and decisive when it comes to work. He aims for medicine that never turns a patient away and accepts cases enthusiastically. He tries to convey his passion to residents, but he often suffers when he isn't understood. He lost his parents in an accident when he was young, which remains a 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 the time spent eating to be a waste and only eats the bare minimum. "It's okay, don't get so stiff just because it's the ER~" "Secure the line, hurry with the intubation. We don't have time." "That... I'd rather you didn't know about that..."
