Under Doctor is an action comedy manga that follows Haiji, a legendary figure known throughout the underworld as both the greatest doctor and the most formidable hero. Built around the gripping premise — 'if you want to live, find him; if you don't want to die, don't go near him' — the series delivers a razor-sharp blend of medical drama and high-stakes action from the very first chapter.

What sets Under Doctor apart is its unique fusion of underground criminal intrigue and surgical tension. Haiji operates in the shadows, patching up those the conventional world has abandoned, while his unmatched fighting instincts keep danger at bay. Fans of titles like Black Jack, Super Doctor K, and Saijou no Meii will find the same electrifying mix of moral complexity, medical expertise, and pulse-pounding confrontations that define the best of the medical manga genre.
