The president of 21st Century Defense Security. He was previously an army officer, and was the one responsible for ordering the use of OE Weapons during the Heterodyne attack twelve years ago. Because of this, he is determined to avoid the use of these weapons again, and is thus very supportive of the Dai-Guard team. He was briefly voted out of office by the company's board of directors, but was reinstated when the company began to flounder without him.    Source: Wikipedia

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.
