In 2055, Tokyo was lost.
Now, it is a city of ghosts.
The year is 2155, precisely one hundred years since Tokyo was ravaged by a ghostquake.
Sealed off from the rest of Nihon, Sector 13 is now a place only spoken about in whispers.
Kichi Honda is a young woman living in Osaka sector, the capital of Nihon City. To escape her unhappy family life and mundane job, Kichi spends her off days visiting Mister Tanaka, an old man who tells her ghost stories and about the last days of Tokyo; information that could lead to both of them being incarcerated, or worse.
Following a hover cab accident that strands her on level one of the city, Kichi meets a young girl named Miaka, who claims to have come from Sector 13.
It is Miaka who leads Kichi to the truth about what really happened in Tokyo and that history is about to repeat itself.
Time is running out.
Kichi Honda may be the only person who can save Nihon City.
That's if the serial killer, Red Raku, doesn't kill her first.
