It’s 2069. Yudai Sayashi’s ragtag club of “treasure hunters”, Durchhalten, was closer to real treasure than they’ve ever been. Overly eager, Yu’s sister Miho ran carelessly towards the vault and triggered a deadly trap that proved to be fatal. Two years later, Yu comes across a startling discovery. The mythical Noah’s Ark turns out to be a real thing and inside is the Lazarus Protocol – a system that can recreate anything from the past. Yu believes Miho can be brought back to life with it and sets out the bring the disbanded Durchhalten back together.
