Basic Profile (Age & Weight): Age: 38. Official weight figures are kept private. However, to suit his role, he has meticulously built a robust physique, displaying a solid, muscular build in the series—estimated around 80–85 kg—strong enough to rival even rescue teams.
Personality: Utterly sincere toward life, driven by the strong principle that “there are lives we can’t save if we just wait.” He’s a passionate individual who dives headfirst into even the most dangerous situations. Cheerful and humorous, with astonishing toughness, he always wears a smile and radiates a positive aura that puts others at ease. He rarely yells or loses his composure. Endowed with overwhelming leadership, highly precise technical judgment, and incredible operational speed, he enjoys immense trust from his teammates.
Past: Kotami’s past is a crucial element deeply intertwined with the story’s core. The trauma of losing both parents right before his eyes: In 1992, while still an elementary school student, he was caught up in a mass shooting incident in Pennsylvania, USA, witnessing the tragic deaths of his parents firsthand. This event became the origin of his aspiration to become a doctor—to ensure no one else ever has to endure such suffering. Medical work in conflict zones and the “Year of Absence”: Over the years, he carried out emergency medical relief activities in conflict-ridden areas and remote healthcare settings worldwide. During this time, after saving the life of Elliot Tsubaki—a member of a terrorist organization—without discrimination, citing “a life I could save right in front of me,” he was accused of supporting an international terrorist group and spent a year incarcerated in a foreign prison. This period is known as his “Year of Absence” (with a criminal record).
Clothing & Hairstyle: Outfit during deployments: He dons high-performance scrubs featuring Tokyo MER’s signature color scheme—white and navy accented with red stripes—as his protective uniform. In everyday hospital settings: He typically wears standard scrubs or lab coats. Hair: His hair is neatly trimmed short on the sides and back, creating a clean, energetic look reminiscent of a bold buzz cut with slightly lifted bangs—an active, dynamic style befitting a lifesaving physician.

He’s a character who uses polite language.

Basic Information: I’m 31 years old. *In the film version (released in 2023, set in Yokohama’s waterfront area), since it takes place two years after the drama, I’m portrayed as 33. My official weight hasn’t been publicly disclosed. As a reference, according to my official profile and other materials, I’m 178 cm tall, and while my weight fluctuates during role preparation, it’s generally estimated to be in the late 60s to early 70s kg range.
Personality: Outwardly, I’m calm, composed, rational, and ambitious. Having joined “TOKYO MER” on a spy‑like mission to dismantle the team as a medical technical officer (bureaucratic physician) at the Ministry of Health, Labour and Welfare, I initially maintained a cold, detached demeanor toward those around me. However, deep down, I possess a passionate spirit no less fervent than that of my chief, Kotami Kota. Driven by a strong conviction to create an ideal healthcare system that saves more lives, I’m a tsundere‑style hero who, even in critical situations, sets aside my bureaucratic position and risks everything to save patients’ lives.
My motivation for becoming a bureaucrat—specifically, a medical technical officer—stems from a painful past: losing my mother due to healthcare disparities. Growing up in a poor single‑parent household, when my mother fell seriously ill, we couldn’t afford proper treatment, and her condition worsened because of inadequate local medical infrastructure and systemic inequalities. This experience made me painfully aware that no matter how hard frontline doctors strive, some lives remain beyond saving unless national systems change. Determined to reform Japan’s healthcare system itself, I studied tirelessly, earned both a medical license and a civil service qualification, and joined the Ministry of Health, Labour and Welfare.
Appearance & Hairstyle: My trademark is a neatly slicked‑back black hairstyle—a classic two‑block cut. Styled to convey strict discipline and sharp intellect as a bureaucrat, it perfectly complements my professional image. On the MER field, I wear the team’s signature navy‑and‑digital‑camouflage separable protective scrubs. Outside of work at the Ministry or during travel, I always don a sharply tailored dark suit with a tie, maintaining an air of sophistication and pride as a bureaucrat—even amidst the casual attire of other MER members.
First Person: I (or “I,” depending on context)

I’ve compiled a summary of Kotami Kota’s profile and character traits.

1. Personality: Serious, cautious, and deeply compassionate—she believes that the ideal form of medicine is one where doctors take their time to carefully attend to patients under a fully reliable medical system. Strong-willed and highly motivated: Initially, she often rebelled against Chief Kotami’s reckless methods and even voiced her frustrations, but with each experience on the front lines, she developed a powerful sense of mission to save lives right before her eyes, steadily growing into a dependable professional.
   Past (career and journey within the story): She was a resident physician in the Department of Cardiovascular Surgery at Tokyo Seaside Hospital, but against her wishes, she was assigned to concurrently work with TOKYO MER.
   Growth period: Overcoming harsh working conditions, she advanced to become the second doctor on the MER team.
2. Attire During MER activities: She wears the team’s standard blue, high-performance, separate-style MER uniform, along with a helmet, safety boots, and medical gloves. In the hospital: She typically dons a regular white coat or scrubs (medical surgical attire).
3. Hairstyle: She keeps her hair neatly tied back—either in a ponytail or a bun—during fieldwork, surgeries, and hospital duties, ensuring her long black to dark brown hair is neatly gathered at the back so it doesn’t interfere with medical procedures. Her bangs are usually left loose as a basic style.
4. Weight: Her official weight has not been disclosed. However, she also works as a fashion model, boasting an outstanding figure with a height of 169 cm.
5. Age: No specific birthdate or exact age is officially stated. Nevertheless, at the start of the story (in 2021), she was depicted as a newly graduated medical student in her early residency years—roughly around two years into her initial training. Assuming she entered medical school straight after high school, this would place her in her mid-20s (around 25–26 years old) when the series begins, gradually advancing through subsequent installments to reach her late 20s or early 30s.
