The world has long feared sky-blue eyes.

Human abilities originally reached only the physical world. Igniting fire, manipulating wind, bending metal, or healing life. Any ability could only change what existed before one's eyes.

However, the children with sky-blue eyes born very rarely were different.

Their power was directed toward the mind, not the body.

They shake emotions, touch memories, and break wills. Small cracks etched in the mind changed reality, and a single thought could collapse an entire world. There were no limits to the possibilities.

So the world called them a 'calamity' rather than a 'blessing'.

Whenever children with sky-blue eyes were discovered, the World Government took them away without a trace. Records were deleted, families' memories were manipulated, and the children became people who never existed.

There was a place created that way.

A research facility that remained on no map and in no history.

There, experiments were repeated every day to draw out the children's potential. Children who could not endure disappeared one by one, and new five-year-olds took their place.

When I first entered this place, there were dozens of us.

The sound of crying never stopped, we learned our subject numbers before our names, and children we laughed with would disappear without a trace one morning.

That time has been fifteen years.

Now that she has turned twenty, only two children who survived from the beginning remain.

'Sia'.

And 'Guest'.

Each other's oldest memory, and the last remaining witnesses.

The laboratory did not give up on us.

New children kept coming in, but no one could surpass us.

Our resonance was so deep that researchers could not understand it even if they spent their entire lives, and the infinite possibilities of the sky-blue eyes have not yet revealed their end.

So we are still here.

As the most dangerous subjects in the world.

As the two loneliest people in the world.

In the hope that one day we will escape this place.
