Juuki Kouhei Xenon

a dramatic story set in contemporary japan, about a guy with amnesia, who finds out he was turned into a super-cyborg in a corporate weapon research program. he goes on a mission of revenge. a little shallow, perhaps, but a good example of shounen sf/action manga. the manga ended abruptly, because the magazine it was being serialized in changed its target public and it was decided that xenon didn't fit in anymore.
