Reaper

Planet after planet exploded like it's some balloon. But unlike a balloon, what accompanied the death of a planet wasn't air, it was endless debris mixed with the sickening scent of blood and death.

Lives in the count of billions evaporated. Only a few silhouettes rushed out of this debris and escaped into distant space. These were strong rank 5s who didn't bear the brunt of the attacks.

But before they could even leave the solar system, their bodies mysteriously dropped dead and vanished. 

The remaining powerhouses of the planet, including the peak rank 4s were dying in the debris as their injuries grew exponentially worse every passing moment.

Perhaps a dozen of them could survive by taking precious elixirs—provided they had them in their possession.

Of course, none of them would survive. They wouldn't allow any survivors. 

For a planet with more than 50 rank 4s, it was a despairing reality. But for the rest, it was a dead end.
