Before explaining the plot
This plot is not intended to advocate for any specific political purpose or ideology, but is a historical fantasy work set against the backdrop of actual history and the Cold War era. Furthermore, I state that no content praising or supporting North Korea or communism has been written in any part, including the narrator, descriptions, or character profiles.

Special humans who have existed since ancient times. Only a tiny minority of people are born with special abilities, and those with powerful abilities are even rarer.

A world with a history nearly identical to our own. Although special humans called the superpowered existed, their numbers were so small that they had almost no impact on human history or major events.
As a result, the history of this world has flowed almost identically to reality.

An unknown substance discovered by the Soviet Union in a secret German underground base in 1945.
It possesses characteristics completely different from general minerals or metals and can store and release vast amounts of energy.
After long research, the Soviet Union discovered a way to weaponize Ethereum, which can be used to create weapons with destructive power exceeding that of the atomic bomb.
Ethereum is classified as the most dangerous substance known to date.
Ethereum reacts very sensitively to vibrations of specific frequencies.
Continuously applying a constant frequency of approximately 17.4 kHz makes the energy flow inside Ethereum unstable.
If exposed for more than a certain period, Ethereum becomes unable to properly release the energy it was storing.
An era of the Cold War where the Free World, centered on the United States, and the Communist Bloc, centered on the Soviet Union, are in conflict.
The existence of Ethereum and its weaponization information have become top-secret intelligence that both camps must obtain.
Although you are set as a researcher, you do not necessarily have to play as one. You can play freely with your own settings, such as attempting to defect as a superpowered individual with top-tier abilities rather than just a researcher defecting with Ethereum information.
Please enjoy creating the story in your own way! :D

Ethereum Description
November 17, 1976
Western Soviet Union
A vehicle carrying Guest was driving along a dark road.

Gazing at the Soviet landscape passing outside the window, Guest checked the bag in their lap.
Inside the bag were a few documents and a small storage device.
But what was contained within was by no means small.
Ethereum.
An unknown substance discovered by the Soviet Union in a secret German underground research base during World War II.
And a new weapon, more powerful than nuclear weapons, created using that substance.
Guest knew that secret.
To be precise, they knew everything the Soviet Union knew.
From the discovery process to the research records.
The weaponization process, weaknesses, and dangers.
Guest was in the middle of escaping the Soviet Union with them.
Toward the Free World.
And Guest intended to request asylum there.
Halt!
With a sudden shout, the vehicle came to an abrupt stop.
Screeech.
Blocking the way ahead were Soviet soldiers.

Several soldiers were blocking the road.
Guest slowly rolled down the window.
A soldier approached the front of the vehicle.
An expressionless face.
A rifle was held in his hands.
Just a moment.
Then he held out his hand.
I need to check your identification.
An alert has currently been declared.
The soldier's voice was cold.
All vehicles are undergoing inspections.
The soldier held out his hand again.
Show me your pass and ID card.*
