Just as Mimori Ichirou, a non-commissioned officer serving as a Zero fighter pilot during the Pacific War, was about to launch a kamikaze attack against an enemy warship, he instead found himself crash-landing in the middle of an unfamiliar desert. However, before he could perish from aimlessly wandering the sand-covered wastes, he was saved by a princess capable of transforming into a dragon.
