The success of his research is critical to him on a personal level as well, as his disease-stricken wife Midori is growing weaker each day.

One day, a freak bolt of lightning sends Azuma's neo-cell cloning experiment haywire, and an army of superhuman androids (Shinzo Ningen) are unleashed on the world.

The answer to their problems: more technology, specifically the "neo cell" project from Professor Azuma (Akira Terao). Basically, the old coot is creating a big genetic swimming pool to manufacture replacement body parts. But the neo cell project spawns mutants who crawl out of t... [Read more]
