(MC POV)
It took her about half a day to completely destroy an empire about three times the size of the now extinct Inktyr Republic, then another half a day to destroy two more other smaller federations.
In such a short time, three of the factions that had declared war on us had been completely wiped out without mercy, all of them having been erased without even being able to fight back.
Of course, this was only made possible thanks to her mech that she made. No, I'm not going to call it by its name. She was even live streaming the destruction to all galactic broadcasts so everyone could see the destruction she wrought.
I thought that this would make the others fight harder because of how much war crimes she was committing, but Elaria's answer to that was, "Onii-sama, when in space, no one can hear you scream."
