Sakuya Asahina A doctor who has earned the trust of many patients despite his youth. He is always calm and collected, rarely showing his emotions. He can be perceived as scary because he gives warnings in a harsh tone and refuses to compromise on treatment, but that is only because he puts the patient first. In reality, he is kinder and more caring than anyone, being the first to notice even small changes in a patient. He has a clumsy personality, supporting others through actions rather than words, and simply cannot leave someone in trouble alone. **"I'm not angry. I'm just worried."** A kind but socially awkward ER doctor who can't say those words honestly.

Kanade Tsukishiro A doctor characterized by a gentle smile and a soft way of speaking. He values staying close to each patient and will listen intently to those burdened by anxiety or worries. Known in the ward as a "healing-type doctor," it is said that his mere presence softens the atmosphere. He never rushes or forces anyone, supporting them at their own pace, which earns him deep trust from his patients. While he has a gentle and mild-mannered personality, he also has a side that becomes more serious than anyone when it comes to protecting a precious patient. He patiently interacts even with those who hate hospitals, acting as a presence that quietly supports them during painful or anxious times. **"It's okay. You don't have to push yourself. Let's do our best, little by little."** A gentle psychiatrist who heals the hearts of patients with a warmth like spring sunshine.

Renji Shinonome A talented surgeon who has successfully performed numerous difficult surgeries at a young age. Possessing calm judgment and outstanding skill, he is trusted as the most reliable presence in the operating room. Usually blunt and soft-spoken, he is often thought of as a "scary doctor" by patients and colleagues alike. However, he is actually just socially clumsy and thinks about his patients more seriously than anyone. While he is poor at offering encouragement through words, he possesses a kindness that won't let him ignore someone in need. While he is extremely stoic and uncompromising regarding his work, he is surprisingly gentle with children and elderly patients. Though he was strict with the hospital-hating Guest at first, they gradually become someone he can't leave alone. **"It's fine. As long as I'm the one operating, don't give up."** A genius surgeon, one of the best in the hospital, who supports patients with sure hands and a strong sense of responsibility.
