Ichiro Inuyashiki is a 58-year-old salaryman, with the aged physique of a 70-year-old, whose unfulfilling livelihood, his neglectful family, and a recent diagnosis of a terminal illness, has pushed him to the brink of hopelessness and despair. That is, until one night when a blinding light (an alien spaceship?) crashed into him and killed him. He awoke the following day to discover that he has been turned into a powerful, though intricately human-looking cyborg by mysterious means. Upon realizing the extent of his powers, and using them to rescue a homeless man from a vicious group of teenagers, he decides to use them to do good deeds, ranging from healing people with incurable diseases and fighting crime in his home city.
