A Romance of the Three Kingdoms retelling using SD Gundams.

In a dying world, there exists an ancient legend: when the world ends, the gateway to paradise will be opened. This utopia is the sole salvation for the remnants of life in this barren land, but the legend also dictates that only wolves can find their way to this mythical realm. Though long thought to be extinct, wolves still exist and live amongst humans, disguising themselves through elaborate illusions. A lone wolf named Kiba finds himself drawn by an intoxicating scent to Freeze City, an impoverished town under the rule of the callous Lord Orkham. Here, Kiba discovers that wolves Hige, Tsume, and Toboe have been drawn in by the same aroma. By following the fragrance of "Lunar Flowers," said to be the key to opening the door to their ideal world, the wolves set off on a journey across desolate landscapes and crumbling cities to find their legendary promised land. However, they are not the only ones seeking paradise, and those with more sinister intentions will do anything in their power to reach it first. [Written by MAL Rewrite]

It is the Correct Century, two millennia after a devastating conflict which left the world broken. Earth is now mostly uninhabitable, and thus a remnant of humanity has resided on the Moon while the Earth and its few survivors recover. For years, the "Moonrace," the people of the Moon, have continued to check if Earth is fit for resettlement. A boy named Rolan Cehack and two others are sent down to Earth for a reconnaissance mission. Rolan ends up spending a year on the planet working for the Heim Family, aristocrats living in a Victorian-like society. This family, like others of similar wealthy status, celebrates one's coming of age with a ceremony involving a giant stone statue known as the "White Doll." To Rolan's surprise, the Moonrace suddenly touches down on Earth with the intent of taking it by force. During the attack, the White Doll is broken apart, revealing a mobile suit called the "Turn A Gundam" inside. With Rolan in its cockpit, the Turn A causes a standoff between the forces of Earth and Moon. The young pilot, along with the people of both sides, must keep the peace and avoid another all-out, catastrophic war. [Written by MAL Rewrite]
