Kyoukaisenjou no Horizon

In a distant future, humanity has abandoned a ruined Earth for a new, artificial world. Yet, even there, history repeats itself. With the original homeland now viable once more, a war-torn humanity must return to reclaim it, but only after re-enacting history one more time, following the guidance of the sacred Testament. However, when the floating city-ship Musashi arrives, its students find themselves at the center of a brewing conflict, as their nation attempts to forge its own path, defying the prophecies of the past. Caught between the strictures of history and the desire for a new future, the students of Musashi, led by their eccentric but powerful student council, must navigate a world of political intrigue, fantastical technology, and ancient mysteries. As battles erupt and alliances shift, they'll find that the true meaning of history might be far more complex — and dangerous — than any of them could have imagined.
