Monsters known as "Horrors" have invaded the world, entering through gates from the Makai Realm of Darkness. These corrupt, demonic creatures have the ability to seize human bodies and feed on their souls. Citizens who are out past sunset will likely never see the sun rise again, but those who live in the capital city have no need to worry—they are protected by a spiritual force field created by the sorcerer group Onmyouji. In possession of legendary armor, the Golden Knight Raikou proclaims that he will protect everyone from the Horrors. Accompanied by his attendant Kintoki and the mysterious Makai Alchemist Seimei, he strives to become a formidable Makai Knight, but Raikou is ill-prepared to handle the side effects of the armor. Disappointed by his own shortcomings, he sets out on a journey of self-discovery to master his weaknesses and prove his worth. [Written by MAL Rewrite]

Serving as a spinoff gag manga of the original Hokuto no Ken series, the story is a parody of Fist of the North Star by Buronson and Tetsuo Hara. It consists of page-long gags centered mainly on Souther, both within his final battle with Kenshiro and inserting himself into other parts of the series where he doesn't belong. One recurring gag involves the kid with a turban repeatedly stabbing Souther in the leg every time he climbs the pyramid's staircase, and another involves Rei suddenly transforming into Souther in his iconic moments.

Many people have fond memories of meeting a certain teenage boy in their younger years. However, their ages vary widely, and each remembers him as a teen. This story follows the intricate intertwining of their various stories and how this young man, who apparently lives outside of time, has affected each of them.

The story focuses and revolves around the 108th Guard Squad, stationed in Aomori. A poorly equipped unit with very little military standing, it is often viewed as a 'reject camp' for pilots not making the grade for the elite units based in Hokkaido. The apparent helpless nature of this force is hardly a deterrent for the encroaching enemy armies, ever closing in on both the 108th and the rest of the empire. The young pilots of the 108th, who had dreamed on returning home, are plunged forcefully and unwillingly into a war.
