Two thousand eras ago, humanity achieved immortality.
One thousand eras ago, humanity discovered a shuttle left behind on a planet by an advanced life form.
But the shuttle could only be used one hundred thousand times.
Two girls became the first test subjects to travel through it.
But since it was the first attempt, none of the technology was fully developed.
An accident happened. To save the other girl, one of them chose to stay in this world forever.
Time passed: ninety-nine thousand nine hundred and ninety-nine years.
She kept traveling through time. At one point, the government abandoned the project.
She used the savings she had accumulated over tens of thousands of years to buy it.
But none of the first ninety-nine thousand nine hundred and ninety-nine journeys could recreate the first one.
So, on this final, hundred-thousandth journey, will she... find her?
