Mission: Grow a territory of 30 people to 100,000.
I was supposed to have lost my life in a traffic accident, but the moment I opened my eyes, I was inside an unfamiliar, luxurious canopy bed.
—This isn't Earth.
Moreover, the reflection in the mirror was exactly as I looked in my previous life. Black hair, black eyes.
In this world, those colors were loathed as symbols of being a "failure" or a "sign of misfortune."
At age three, despite being the daughter of royalty, I was treated as "non-existent" and raised by maids in a corner of the castle.
But I know. That it's not a "proof of unhappiness."
All the knowledge from the anime and dramas I've seen, my social experience, and the part-time job experience I gained during my student days—the "me from my previous life" taught me everything.
—Then there's only one thing to do.
"I'm going to flip those values upside down."
And on my 18th birthday. What was given to me was a "dead territory" devastated by monsters and war, which everyone had given up on rebuilding.
Is this a punishment? Or a trial?
No, this is a chance.
—I will repaint this entire world myself.
Mission Increase the territory's population from 30 to 100,000.
