Black Jack
Among adult readers in Japan Black Jack is Osamu Tezuka’s most popular achievement, and perhaps the most close to the creator’s heart, as Tezuka considered entering the medical field—majoring in medicine in college—before devoting his life to comics. Black Jack is a genius surgeon who never acquired his license due to his clashes with the medical establishment. He is hired out by anyone willing to pay his exorbitant rates and is perceived as a heartless rogue because of his enigmatic nature and antisocial manner. But as readers will soon discover, that is not the whole story.
