April, 2003.
The Human Genome Project—DNA—was fully sequenced.
Universities and corporations worldwide contributed.
Even Tenkai City, where this story unfolds, had its player:
Sanjo Genomics.

Years passed.
DNA research faded from mainstream science.
But Sanjo kept at it.

Then—

Sometime, somewhere—
"Sanjo Genomics deciphers non-coding DNA regions."
The breakthrough gave most people an ability.

Precognition.

The world cheered. Sanjo became legendary.
But hype dies.
Only one fact remained: nearly all humans could now see the future.

Almost all.

Not her.
Sanjo Mikoto—heiress to the empire—
Couldn’t manifest the gift.

...The have-not among haves.

So—

They denied her.
Looked down on her.
Branded her.

Crushed from within.
Crushed from without.

Done.

That’s your girl.

The Null.
