Waking up from a dream, I suddenly find that I have lost my name. I'm scouting around but the world becomes odd and weird, leading me back to somewhere familiar...
A, the last human on the planet. X, the god, demon, or the future in A's nightmares. In 1972, a futurologist book precisely predicted the human destiny manifested in East Asia. In an unknown era, the last human found a mysterious message from an electronic device and embarks on a quest for a future from the past. In ten chapters, the audience explores this dream-like prophecy.
