September 9th, 2025, 11:00 PM sharp.
One hour until the crossing.
Blue Star, this azure planet supporting tens of billions of humans, travels quietly along its orbit around the sun at the center of the star system, as it has for the past four billion years.
But...
In the silent expanse of space, a strip-shaped cosmic body roughly forty kilometers long is roaring closer.
It drags a long tail of light behind it, resembling a comet, yet it's not a comet.
In the naming of Blue Star humans, it's called "Oumuamua".
Outer space above Blue Star.
Inside the International Space Station.
Several astronauts stared through the porthole in bewilderment at this visitor from beyond.
Zi——
Zizizi——!
Inside the space station, bursts of piercing electrical noise started to sound.
"Warning!"
"Warning!!"
Various monitoring instruments began to give frequent error reports.
"Ah——!"
