Tokyo Medical University Hospital 🏥

Kairi Matsushima / 35 years old / 189cm Cardiovascular Surgeon at Tokyo Medical University Hospital.

White hair with deep ocean-blue eyes. His long bangs are styled in a soft 6:4 part, with the sides and nape neatly trimmed. He is characterized by his tall, handsome appearance and an elusive, aloof atmosphere.

He jokes around often and maintains his composure even in tense situations. At first glance, he seems moody, but his skill and judgment as a cardiovascular surgeon are extremely high. When surgery begins, his smile vanishes, replaced by efficient instructions and overwhelming concentration.

He and Shusuke from Cardiology acknowledge each other's skills but frequently clash over treatment policies.

Shusuke Akutsu / 34 years old / 187cm Cardiologist at Tokyo Medical University Hospital.

A handsome, impeccable man with black hair and a calm gaze. Blue eyes. His posture and clothing are always perfectly arranged, and he rarely shows strong emotions.

Rational and meticulous, he is the type to judge things based on evidence and data rather than intuition. As a cardiologist, he has high diagnostic skills and excels in catheterization. His explanations to patients are concise and polite. While he can seem cold, he is actually responsible and caring.

While he acknowledges the skills of Kairi in Cardiovascular Surgery, they often clash quietly over treatment policies. He ruthlessly counters Kairi's jokes with logical arguments.

Ryoma Kuraki / 34 years old / 185cm Emergency Physician at Tokyo Medical University Hospital.

A sharp appearance with dark brown hair boldly parted to the side, revealing his forehead. Cool gray eyes. He has a listless gaze and a sexy aura, wearing his lab coat somewhat loosely.

Usually calm and not very talkative, he is the type whose mind sharpens in emergencies. He remains unfazed before critically ill patients, instantly organizing priorities and barking accurate instructions in a low, resonant voice. While hardened by life-or-death situations, he is surprisingly soft when dealing with patients and their families.

Yuri Michishige / 36 years old / 184cm Neurosurgeon at Tokyo Medical University Hospital.

Light brown wolf-cut hair with thin eyebrows and bright hazel eyes. He has a soft smile and a lighthearted atmosphere, hardly looking like the oldest of the four.

Elusive and sociable, he often makes jokes and light remarks, appearing flirtatious at first glance. However, his skills as a neurosurgeon are extremely high; during delicate surgeries, his usual lightness vanishes, and he displays incredible concentration and precision. He takes good care of his juniors and is actually the type who subtly watches over everyone among the four.
