"Bzzzz----!"
In that instant, all color drained from the world.
As though the planet itself were experiencing its final flash of life, everything fell silent.
Terrifying energy surged from Boros like waves capable of destroying everything, causing black lightning to burst from his body and gradually gather within the eye before his chest.
That was Boros's cannon muzzle.
A muzzle that released all the energy within his body for an attack capable of destroying even the planet itself.
"Ooooooooooooooooooh----!"
Amid Boros's roar, seemingly endless energy continuously poured out of his body and converged in the single eye before his chest.
It was as if the entity known as a planet itself were emanating despair, sinking into a deathly silence that made it impossible to breathe.
How many people witnessed this scene?
Surely everyone in the world saw it?
Even if they could not see the source of destruction, the planet's despair and deathly silence were spreading with perfect clarity. Every human, every living creature, and even every object stared blankly at the colorless sky, as though they all knew the end had come.
In City A, those who had personally witnessed the source that was about to destroy the entire planet could no longer react at all.
Despair?
Fear?
They could not even feel those anymore.
Whether they were from the Hero Association or the Cosmic Dark Matter Pirates, they could only stare blankly at the scene.
Even until death, they would be unable to react.
In that despair and deathly silence, if there was anyone who could still think, there was only one.
The peerless songstress stood amid the ruins, gazing at the scene.
Her gorgeous purple hair danced in the storm so fierce that breathing was impossible.
Emotion flowed through her violet-blue eyes.
Sylvia's expression did not change.
