One of the amazing things about manga is the longevity and continuity that can be attained by a single author working on a single series. Sure SUPERMAN, BATMAN, and SPIDERMAN have been with American comic book readers for many, many years. But none of those have been under the guidance of a single pen. At the very least, the storytelling duties are often split between an artist and a writer.
Quite frequently in the world of manga a single author both writes the story and draws the art, providing a longevity and continuity that makes the work more attractive as the readers come to rely upon how the story will flow and eventually reach a resolution.
CHOJIN LOCKE ("LOCKE THE SUPERMAN"), written by Hijiri Yuki, is a story that has gone on so long that it has outlived four publishers. One rumor circulating is that the story will outlives its publishers just as the main character in the story outlives everything around him.

The Story

At first glance the story is simply about Locke. He has no family name; when asked "Locke what?" he replies "Just Locke." His genesis is before the "Cosmic Year" calendar used in the story. Although there are rumors that the author has an origin in mind for Locke, it is still a mystery to readers as well as to the other characters in the story. All of the stories deal either directly with Locke or with actions only slightly removed from him. The primary plot deals with Locke's involvement in struggles against evil of one sort or another—either human or quasi-supernatural. Frequently Locke is drawn into events that are happening around him. Either he stumbles onto a situation that his heart will not let him ignore, or one of the other players begs him to join their cause. Sometimes he relents and joins their cause; sometimes he ends up opposing them.
As the story slowly grows around the reader (and there is a lot of story!) he finds that it is a chronology of human history in the future. Locke is the medium through which we see humanity as it evolves, travels, discovers, explores, colonizes, conquers, fights, and destroys. He is the eye on humanity. He is also the will to do right.
