It’s 2069. Yudai Sayashi’s ragtag club of “treasure hunters” (referred to as looters by those who know them), Durchhalten, was closer to real treasure than they’d ever been before. Overly eager, Yu’s sister Miho ran carelessly towards the vault, triggering a trap that killed her.
Two years later, Yu comes across a startling discovery. The mythical Noah’s Ark, borne of legend by those who believe the Old World can be restored, turns out to be a real thing.
With the help of the kid genius Toshio, Yu learns about the existence of the Lazarus Protocol inside Noah’s Ark – a system that can recreate anything from the past – a machination developed during the time when humanity’s survival was uncertain. Using the Ark, Yu believes Miho can be brought back to life.
Before setting out to find the Ark, however, Yu wants to reunite the now defunct Durchhalten. The group had disbanded after the tragic incident two years ago, and he wants everyone to be there when Miho opens her eyes once more.
