Prologue

On November 1, 2008, a mysterious individual calling themselves "Satoshi Nakamoto" began publishing a paper on a cryptography forum's mailing list about a completely new decentralized digital currency called "Bitcoin" that had no bank or single administrator.

This technology was revolutionary enough to transform the way the world worked. The person behind it vanished from the internet in April 2011 without revealing their true identity.

Then, one day after more than a decade had passed, the "real" Satoshi Nakamoto suddenly appeared on social media and declared, "To the one who gathers all the codes, I will give away all the Bitcoins I possess."

It is said that Satoshi Nakamoto owns over 1.1 million Bitcoins (worth approximately 32 trillion yen).

As people all around the world become obsessed with searching for the "Satoshi Code," a regular office worker named Mitsuhiro Akutagawa accidentally comes across a hint connected to the code. In his pursuit of the Satoshi Code, he becomes entangled in a series of mysterious events.
