On one of the countless planets in the universe lived a creature who called itself Grumi.

Grumi always carried a strange device with it. No one knows whether it was always so hostile, or if this sinister tool changed it over time. No one knows where the device came from. But one thing is certain — when activated, it affects everything around it. The signal it emits carries only one thing: anger. In truth, Grumi is harmless when left alone. It always believed it was the only living being on the planet. But one day, its quiet solitude was disturbed by other creatures that began to appear on its territory. Frightened and confused, Grumi uses the device to drive them away. But the device does not work the way Grumi thinks. The signal does not simply scare others — it changes them. Creatures exposed to the beam become increasingly aggressive. And if they remain under its influence for too long… the effect becomes irreversible. Now Grumi must face the consequences of the signal.
