The pattern of quakes suggests that the worst Heterodyne yet is about to appear, but when it shows up five thousand metres above Shinjuku and does nothing, no one is quite sure what to make of it.

Dai-Guard
Thirteen years after their sudden disappearance, an alien race known as the Heterodyne resurface without warning. To combat the Heterodyne, three office workers from the 21st Century Security Corporation operate Dai-Guard - a giant robot no longer regarded as an oversized paperweight. Unfortunately, Dai-Guard is somewhat obsolete and in disrepair. It's a tough job, but salarymen can also save the world.
