Juuki Kouhei Xenon

A man suffering from amnesia in modern-day Japan discovers he is a super-cyborg created by a corporate weapons research program. Seeking revenge, he embarks on a mission tied to his altered identity. The manga, while somewhat superficial, fits the conventions of shounen science fiction and action genres. Its serialization ended suddenly due to a shift in the target audience of the magazine, making the series no longer suitable for continued publication.
