In the forbidden lands, Orochi was slain.
It was something that had happened time and again in this world — or so it was supposed to be.
When the hunter Homura struck off its head, the corpse did not vanish.
Instead, a girl appeared. She was alive — but remembered nothing, not even her name.
Abandoning her would have ended it all.
But Homura chose otherwise.
To restore the girl’s lost memories, she chooses to enter her dreams — to walk through a world shaped by memory and search for the source of the nightmare.
Yet once inside, Homura faces a single dilemma: to end the nightmare — or to let it remain.
The scenes witnessed in the dream quietly begin to overlap with reality.
