IRYU: Team Medical Dragon is a gripping and intense Japanese drama series broadcasted on Fuji TV in the year 2010 following immense popularity of its previous seasons. The show is based on a sensational manga of the same name by Akira Nagai and draws heavily from the themes and aesthetics of the original work.

The series portrays the ever-evolving field of medical science with a graphic and realistic lens. The plot focuses on the bracing encounters and struggles of a genius surgeon named Ryutaro Asada, popularly referred to as Dr. Dragon. Asada possesses exceptional surgical skills and deeply rooted principles about the preservation of human life. However, his unorthodox approach to medicine often sets him at odds with the harsh realities and the existing bureaucratic system of the medical world that emphasizes more on protocols over patient welfare.

Acknowledging Asada’s extraordinary capabilities, Katou endeavors to assemble an elite surgical staff that would pioneer a new wave of medical care.

His commitment towards patient-centric care and life preservation, regardless of his own reputation or personal loss, makes him a compelling hero.

Akira Katou is shown as a fiery, ambitious woman who brings Asada back from his secluded lifestyle with the purpose of taking on the bureaucratic medical system.
