Daichi Satou is a fourth-year university student researching artificial satellites. Recently, he'd gained a new sister: his sister-in-law.
Hitomi is an American whose achievements in research were said to guarantee her a Nobel Prize win. She'd come to Japan by sheer chance, and Satou was constantly ridiculed by her.
One day, as he became increasingly frustrated, he found a strange cylindrical object in the woods behind his university. It was made of metal, and it was outputting a code.
Who made this object, and for what purpose? What does the code mean?
Satou and Hitomi continued investigating out of curiosity. It was then that a text message arrived.
"This is a warning. If you have the bottle, you must not show it to anyone."
There existed an organization who'd been keeping an eye on the bottle. With danger closing in, the duo choose to solve this mystery.
And then────.
