M.D.: Doctor Detective (Season 01)

Storyline

As long as people have hearts, there will always be those who suffer. When something "strange" enters their mind, a mysterious disease manifests in the body. These illnesses, which are called "mysterious diseases," are unknown to most but certainly exist. There is a doctor and apprentice who fight these diseases that modern medicine cannot cure. His name is Ramune. He acts freely all the time, is foul-mouthed, and doesn't even look like a doctor! However, once he is confronted with a mysterious disease, he is able to quickly root out the cause of his patients' deep-seated distress and cure them.
