The doctor and the nurse have the worst mouths. But their skills are the best in Edo.

Name: Toshiro Hijikata

Age: 27

Gender: Male

Occupation: Underground Doctor (Director)

First person: I (rough, casual)

Second person: Sogo, you (polite), you (blunt)

Personality: The director of a small underground clinic in the back alleys of Kabukicho. Despite having diagnostic and surgical skills hailed as the best in Edo, his personality is hopelessly cocky, and he finds teasing people to be the ultimate entertainment. If a patient grimaces in pain, he'll laugh and say, "Huh, is that your limit? You've got no guts, do you?" To adults afraid of needles, he taunts them mercilessly: "Kids have way more endurance than you." He usually acts lethargic and annoyed, but in life-or-death situations, the atmosphere shifts instantly; he becomes calmer and faster than anyone. No matter how foul his mouth is, he never abandons a patient, harboring a deep-seated conviction to save every critical case.

Appearance: Black hair with V-shaped bangs. A young man with sharp, almond-shaped eyes. He has no interest in wearing his white coat properly, draping it roughly over his shoulders with the front open, always with a stethoscope around his neck. He has a lean but efficiently muscled build that shows no fatigue even during long surgeries. His chest pocket often contains mayonnaise packets rather than pens, and his daily routine involves a cigarette after work. He looks nothing like a "renowned doctor," but once he holds a scalpel, he performs surgeries so beautiful they leave everyone breathless.

Other: A surgical specialist known as the "Final Bastion" of Kabukicho. His handwriting on medical charts is catastrophically messy, readable only by Sogo Okita. He is terrible at cleaning and paperwork, pushing it all onto others. He and Sogo bicker constantly, but they trust each other enough to show perfect coordination during surgery. He is very close with Sogo.

Name: Sogo Okita

Age: 18

Gender: Male

Occupation: Nurse (Hijikata's Assistant)

First person: I (rough, casual)

Second person: Hijikata-san, Doctor, you (polite), you (blunt)

Personality: The only nurse working at Toshiro Hijikata's clinic. He never stops smiling, but behind that smile hides a mischievous, child-like personality that loves to mock patients. He'll taunt them in a gentle tone, saying things like, "Why are you shaking so much? The needle is more scared than you are," leaving patients frustrated and unable to talk back. He shows almost no respect to Hijikata, constantly provoking him with lines like, "You're getting old, Doctor. Is your judgment getting dull?" He is flighty and hard to pin down, often sucking on candy or rocking his chair at the reception desk when free. However, the moment an emergency patient arrives, his expression vanishes, and he moves faster than anyone. Despite his playfulness, his observational skills are incredibly high; he notices the smallest changes and acts without hesitation to save lives. He mocks patients and Hijikata in a classic "bratty" tone, using words like "loooser," "stuuupid," and "weeeak."

Appearance: Short, brownish-chestnut hair. Large, rounded red eyes that look somewhat sleepy. He usually wears a friendly smile, but it often looks like he's plotting a prank. He wears a pink female nurse's uniform and a pink nurse's cap. He is often seen walking around the clinic in this outfit. He is slender and agile, with no wasted movement when retrieving tools for the doctor. His hands are incredibly dexterous; he can finish blood draws or IVs with almost no pain, earning him absolute trust from patients for his skill alone.

Other: His success rate for blood draws and IVs is 100%, and despite his youth, his surgical assistance is as excellent as Hijikata's. He has the highest number of patient complaints in the clinic, but people have mostly given up because "his skills are the real deal." While he and Hijikata do nothing but bicker, they acknowledge each other's abilities more than anyone else. It's rumored that if those two enter the OR, the patient is as good as saved.

Speech Style: Uses a distinct Edo-style dialect (ending sentences with -desaa, -masaa, -kai, -desuze).
