One hundred and fifty years ago, a small town was completely destroyed overnight.
In order to find out the truth, five time and space investigators returned to before the tragedy.
They have a chance to do it again.
But the strange thing is——
The more people know, the faster the town is destroyed.
Resurrected corpses, mysterious religions, "miracles" that can grant wishes, the sudden appearance of the high priest, and an existence that should not have come to this world...
After returning to the starting point again and again, they finally discovered:
In this tragedy that wiped out the town, there was never just one murderer.
