Description
Masato Yamanobe is the protagonist of the Future chapter of Osamu Tezuka's Phoenix, set in the distant year 3404. He holds the rank of Class 2 space warrior and serves the underground city-state of Megalopolis Yamato, one of several human settlements existing beneath a dying Earth's surface. Humanity has largely abandoned the surface world and now lives under the management of an electronic brain system that dictates the population's actions and commands.

Masato's background as an elite astronaut places him within the upper echelons of this highly controlled society. He possesses the training, skills, and status expected of a military specialist in a civilization that has retreated underground. However, his central trait is not his professional competence but his capacity for compassion and rebellion against authority. When his superiors order him to kill his girlfriend, Tamami, on the grounds that she is an outer-space creature originally known as Moopie who has taken human form, he refuses. Instead of following the command of the system he serves, he chooses to protect Tamami, and together they flee across the barren, deserted surface of the Earth.

Masato's motivations are rooted in loyalty and love. He is willing to become a fugitive and abandon the only society he has known to safeguard a single life deemed expendable by the state. This defiance sets the entire narrative of the Future arc into motion, as he is pursued by his former colleague and superior, Rock, who represents the rigid, unforgiving will of the underground city.

His key relationships include his bond with Tamami, the alien shapeshifter he protects, and his adversarial dynamic with Rock. After escaping the pursuit of the authorities, Masato and Tamami are guided by the Phoenix itself to the isolated dome of Dr. Saruta, a scientist who has dedicated himself to reviving extinct life forms. Dr. Saruta, in this era, serves as an enigmatic mentor figure and a symbol of rebirth, echoing the recurring Saruta character that appears throughout the Phoenix saga.

Masato's role in the story becomes increasingly monumental. After the five underground cities of humanity descend into a total war that leads to their complete annihilation, Masato is entrusted by the Phoenix with the task of reviving the Earth. As part of this mission, he is granted an immortal body, setting him apart from ordinary humans and binding him to a vast, cosmic perspective. He is no longer merely a fugitive or a soldier; he becomes a witness to the entire cycle of life and death on the planet, enduring across millennia as he observes the slow processes of biological evolution and the re-emergence of life on a barren world.

His character development is profound. He begins as a dutiful, elite member of a tightly controlled society, but his personal choice to rebel transforms him into a symbol of individual will. His journey forces him to abandon human society entirely and ultimately transcend his own humanity. The gift of immortality is not portrayed as a simple reward but as a profound and isolating responsibility, compelling him to grapple with themes of loss, solitude, and the relentless passage of time.

Notable abilities include his professional expertise as a Class 2 space warrior, which implies combat training and familiarity with advanced technology. More significantly, he is endowed with immortality by the Phoenix, which allows him to survive the extinction of the human race and the vast geological and biological transformations of the Earth. This ability defines his ultimate role as the lone custodian and eventual progenitor of new life on the planet, a position that connects him directly to the central themes of life, death, and rebirth that permeate the entire Phoenix narrative.
