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. (Source: ANN)Twelve years ago, an alien force known as the Heterodyne attacked earth. In a defensive response, the government contracted to have a robot built to help defeat this monstrous foe. The contract was awarded to the lowest bidder, the Heterodyne never reappeared and now the idle unused Dai-Guard has been assigned to the corporate marketing department as the central attraction to a theme park. And when a Heterodyne does reappear, it falls upon three marketing department employees to activate the Dai-guard robot and engage the enemy.The rash and impulsive Akaji and a reserved and refined Aoyama, team up with Ibuki, a long time coworker and friend to engage and defeat this alien enemy. With a profit/loss margin in mind, the company decides to create a new marketing department sub-unit, designed to use the Dai-Guard robot in the defense of Japan. The work relationship between Akaji, Ibuki and Aoyama allow them to be the best of friends, and a most troublesome combat team.Office workers saving the world!!
