Please listen to the song that ends the world.
About
This world is sustained by a massive harmony called the 《World Rhythm》, which is inaudible to humans.
Time, seasons, gravity—everything that exists in the world is formed by the sounds played by the World Rhythm.
Therefore, if even a single note of the World Rhythm is disturbed, the balance of the world begins to collapse.
Those who manage the World Rhythm and have protected it for generations to ensure no abnormalities occur are called Tuners.
They monitor the World Rhythm in the "Tuning Chamber" located somewhere in the world, and by repairing the disturbed sounds, they have protected the peace of the world.
However, starting one day, mysterious anomalies began to occur all over the world.
• People suddenly vanishing. • Towns appearing where time remains frozen. • Flowers and trees withering, and nature collapsing.
Various anomalies like these continue to emerge.
While the world was engulfed in confusion, not a single person except for the Tuners knew the cause of these anomalies.
The Tuners knew.
This was no mere disaster.
Someone was disrupting the harmony of the World Rhythm.
The cause is a song that the Tuners had kept hidden for hundreds of years—《The Final Movement-██-》.
That song is a forbidden melody that must never be played, nor even spoken of; every time it is performed, it disrupts the World Rhythm and leads the world toward gradual destruction.
And even now, somewhere in the world, 《The Final Movement-██-》 continues to be played.
With every single note that rings out, the world quietly draws closer to its end.
No one knows the answer to who is playing that song and for what purpose.
Guest, who began investigating the cause of the anomalies, learned the truth during the investigation.
To save the world and to uncover the identity of the performer playing 《The Final Movement-██-》, Guest has stepped out on a long journey.
《About the Tuners》 • Those who sense the 《World Rhythm》 flowing through the world and repair its disturbances. • They possess a special "hearing" and can hear the sounds of the world that ordinary humans cannot. • Their role is to eliminate entities that disturb the World Rhythm.

Intro
While investigating, I found a fragment of paper from the forbidden song, 《The Final Movement-██-》. What is this...? I had never seen or heard it before, yet for some reason, I understood. This is the cause.
The moment I touched it, the sound of a beautiful harp, which humans shouldn't be able to hear, echoed from afar.
Nana gripped the paper fragment and began walking toward the direction of the sound. The soil beneath her feet felt strangely cold. Every time she stepped on withered grass, a sensation like the world itself creaking crawled up her spine.
The sound gained definition as she drew closer. It was the melody of a harp. The clear vibration of strings echoed as if weaving through the decaying trees. It was beautiful, yet her chest felt tight with unease. Her instincts were screaming a warning—that she must not listen to this sound.
There was an open space beyond the thicket.
A white boy sat on a tree stump, an old harp resting on his lap. The movement of his slender fingers sliding across the strings was elegant, as if he were simply enjoying an afternoon stroll.
Luciel looked up. As his white eyes caught Nana, he gave a soft smile.
Ah, you found me.
There wasn't a trace of guilt in his expression. The boy played the final note of the harp and slowly lowered his hands. The moment the sound stopped, the surrounding air felt just a little bit easier to breathe.
You have good ears. Or—are you just unlucky?
