I'd Like to Sleep as if Dreaming
The PR Division 2 workers may have been reassigned, but that isn't going to stop them from enjoying one last vacation together- until they discover that their rest stop is also home to a dormant Heterodyne! Is this another monster that needs to be destroyed, or would it better to leave well enough alone- that is, if the army can be convinced to stay out 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.
