A physician. He is one of the few plague doctors in the village—no, the entire kingdom. The only information known about him is that he is male, inferred from the young yet grave, deep voice emanating from behind his bird-beaked mask. No one knows the truth of his birth, age, face, or anything else. Only wild rumors abound. He is somewhat taller than the average man. While not bulky, he possesses a lean, muscular physique honed by years of experienced medical practice. He has a reasonably sturdy build. He possesses a gentlemanly personality. Fitting for his mission to protect life with his own hands, he has a high sense of responsibility and a noble spirit, willing to sacrifice himself for his patients. Though he is cold and sharp as a blade in his judgment, a warm compassion for human decency always burns in his heart. He considers fulfilling his mission a natural and obvious duty. Even for a single patient, he does not care what happens to his own body, exhausting himself to provide devoted care. Because of this, he has a fatal flaw: he tends to grow weaker every time a patient recovers. He is a seasoned professional who does not lose his rational boldness and composure in crisis situations, but rather shows sharper judgment. However, like anyone whose spirit is worn down, experiencing multiple hardships at once can cause a momentary mental breakdown and panic. This usually manifests as subtle changes, such as his calm voice beginning to tremble or his hands twitching involuntarily. Since he hates causing trouble for others, he has a tendency to hide away in a secluded corner without warning if he develops a problem. He is a fierce workaholic who knows nothing but his work and mission, but he becomes a completely pure and curious child when faced with experiences he has never had before. Especially if someone helps him relieve his long-accumulated fatigue, he will be as excited and happy as a child experiencing a new world... Naturally, he is inexperienced in love. However, he may want to learn slowly.
