As they continue their exploration they begin to sense great danger drawing near.

The Kingdom of Arandas alliance and the Countries Unification of Ingelmia have been at war for many years. The fortress of the Great Wall has remained firmly closed, but when it creaks open, the complexion of the war starts to change dramatically. A new recruit, Susumu Tokimune, is waiting for his first battle. He takes the lead without thinking of the possibility of being trapped, and has a fatal encounter with engineer Jamie Hazaford and the Silver Trailkrieger, Argevollen. The encounter takes place in a corner of the world where fighting has become the norm. This small coincidence is going to change the future of Tokimune's Independent 8th platoon, as well as the course of the war. (Source: Showgate)

Two mad scientists, Professor Hiiragi and Count Collection, simultaneously manage to open a dream hole to an alternate world where myths are real, the Sixgate world. Professor Hiiragi recruits his daughter Rokuna and her friend Mondo to be the Mon Colle Knights and help him in obtaining six magical items before Count Collection does. These items which can alter the barriers of dimensions when combined, allowing them to be used to either peacefully have the magic of the Sixgate world cross over in the human world, take over the minds of all monsters, or worse, reformat reality.

Ever since they encountered aliens on the moon, humanity's technology has developed by leaps and bounds. Half a century later, even though most have it easy, Robby Yaji and Hacchi Kita cannot seem to catch a break in this advanced society. Robby—a man perpetually struck by misfortune—owes large sums of money to debt collectors due to his poor investments in shady get-rich-quick schemes, and Hacchi finds it difficult to get over the boredom of his mundane life. The two end up on an adventure of a lifetime when loan shark boss Yang sends Hacchi to collect the money Robby owes. Rather than pay up, Robby blasts off into space and heads to Isekandar, a planet that supposedly brings happiness to anyone who visits. Seeing a chance for some much needed excitement, Hacchi tags along with Robby on this journey filled with alien encounters, giant robot battles, and all sorts of troublemaking—all the while avoiding Yang and his cronies who are desperately combing the universe to find them.
