After the great war, people left their home planet and moved to another, perfect "celestial world." Soon it collapsed, and the seers discovered that humanity must return home and experience ten thousand years of history anew—only then will it earn forgiveness and restore the path to the stars. On Earth, the "returnees" found only one livable corner (of course Japan!), inhabited by a few remaining natives. Not wanting to be cramped, the "advanced" created a parallel dimension and began an ambitious project of recreating world history. Unfortunately, at the level of the 17th century of the New Era someone made a mistake; the pocket world collapsed, and its inhabitants found themselves on old good Earth. Without ceremony, the "new earthlings" expelled the local residents, whose science—resembling magic—could not compete with the power of the aliens. Now the outcasts live on huge flying ships and amass strength to deal with the "masters of life" and return home. The only way to do this is not total war, but participation in the renewed historical reconstruction—exactly from the era of Warring Lands. And here on the ship "Musashi" gathers an elite of young fighters from far future Japan—from the revived Ganda to the formidable dango bun. Their leader, Tori Aoi, a chosen one of destiny and genetic general, is preparing to perform an act that will turn the course of history. And after that—whoever wins is right!
