Story
The series begins with Kiichi, aged three, and living with his parents. In the second volume they are killed, and he runs away from home. After living with some homeless people for a while, he ends up surviving in the woods by himself for nearly a year before being returned to his grandparents.

The second arc of the story begins with Kiichi in fifth grade, teaming up with a much more verbal and intelligent friend. They attempt to save a girl from classroom bullies, and then discover her father is forcing her to work as a prostitute. Political pressure keeps the police from doing anything about it, and they are forced to stage a hostage crisis in front of the capitol building to gain media attention.

Kiichi VS takes place ten years later, and finds Kiichi running a large organization dedicated to improving the world.
