Like Dr. Ochanomizu, Saruta is visually identifiable by his large nose, though in his case it is grotesquely spotted. Where Ochanomizu generally appears in light and uplifting roles, Saruta is quite the opposite. His two main roles in Tezuka manga are both in extremely important series: Black Jack and Phoenix. In Phoenix, he is arguably an over-arching protagonist for the series as a whole, alongside its title character. He appears in every story, sometimes in a main role, sometimes in a peripheral one, sometimes with a new name and barely recognizable in his character, but always present and important. He is also distinguishable by the sheer amount of suffering he undergoes over the course of his many lives and deaths, as he demonstrates both the darker sides of human nature and the human capacity for perserverance and transcendence.  In Black Jack, he is featured as Dr. Honma Jotaro, once a skilled and famous surgeon later thrown out of the medical community due to jealousy and doubt about his research, who saved young Black Jack as a child, was Black Jack&#039;s principle father figure during his life, and inspired him to become a doctor. Since Saruta is the character in Phoenix who best understands the system of reincarnation, life and death, it is appropriate that in Black Jack Dr. Honma is the figure who most frequently reminds Black Jack about the power of nature and the inevitability of death.

"All things are born and all things die. That is the law of heaven." According to legend, the Bird of Fire called the Phoenix is the eternal spirit of life, death and rebirth. She oversees the cycle of reincarnation and the rising and falling of civilizations and species. Those who can obtain her blood will be granted eternal life, while to others she can grant infinite wisdom, or eternal suffering. Throughout history, from the dawn of civilization to the extinction of the human race, those human souls touched by the Phoenix have hunted her over and over in multiple reincarnations, and their actions in one life determine or reflect the sins and sufferings of other lifetimes.

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.
