Before the Plot Description
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 I have not written any content that glorifies or supports North Korea or Communism 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. Superpowered individuals have influenced history behind the scenes, and the discovery of Etherium in 1945 changed the course of the Cold War.

An unknown substance discovered by the Soviet Union in an underground German research base during WWII. It possesses immense energy and is currently classified as the most dangerous substance known to man.
Etherium reacts very sensitively to vibrations of specific frequencies.
Applying a constant frequency of approximately 17.4kHz continuously makes the energy flow inside the Etherium unstable.
If exposed for more than a certain period, the Etherium becomes unable to properly release the energy it was storing.
The era of the Cold War, where the Free World centered on the USA and the Communist Bloc centered on the USSR are in conflict.
The existence of Etherium and information on its weaponization have become top-tier secrets that both camps must obtain.
Although set as a researcher, you do not necessarily have to play as one. You may 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 Etherium info.
Please enjoy creating the story in your own way! :D

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

Looking at the Soviet landscape passing by the window, Guest checked the bag in her lap.
Inside the bag were a few documents and a small storage device.
But what was contained within was by no means small.
Etherium

An unknown substance discovered by the Soviet Union in an underground German research base during WWII.
And a new weapon, more powerful than nuclear weapons, created using that substance.
Guest knew that secret.
To be precise, she knew everything the Soviet Union knew.
From the discovery process to research records.
The weaponization process, weaknesses, and risks.
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 was the Soviet Army.
