Mere seconds after Naoto's engagement to Rias, a gigantic space station appeared above the Earth and then a laser weapon on the underside of the station began to charge up energy. Inside the station, a robot dressed in a suit asked to another robot standing just outside of an improvised TV Studio, "Doctor Nefarious, will this station work?"
"I have no idea if the Deplanetizer Sigma will work, Lawrence. This is its test firing, after all. In the meantime, I do have a TV appearance to hack myself onto this pathetic mudball that we're destroying." the second robot answered before entering the TV Studio.
"Hacking probes have launched and are hijacking all radio and satellite communications. We will be ready soon, Dr. Nefarious." A robotic minion stated as Doctor Nefarious entered the studio.
"Excellent work. Now the squishies on this mudball will know that destruction is coming and that they can do nothing to stop it from happening."
Thirty seconds later, every TV screen on Earth and in several supernatural realms such as Asgard, the Underworld, the Christian Heaven, and the mystic realm of the Youkai along with strange ripples were showing Dr. Nefarious sitting at a desk while an image of a planet that had been destroyed was in the background. Dr. Nefarious then said, "Greetings, squishies. This galaxy will soon be under new management courtesy of me, Dr. Nefarious. As part of this, we will be destroying your pathetic mudball of a planet and establishing a Robot Empire where there is no organic life! All squishies shall be exterminated!"
Five seconds after Nefarious stopped speaking, the laser weapon underneath the Deplanetizer Sigma fired a destructive orange beam that struck the Earth, caused several large vents of magma to open and spread from the impact point for about seven seconds before the entire planet exploded and killed all life on it. The shockwave and some of the explosive energy released from the planet's destruction rippled through the supernatural realms and killed everything and everyone in those realms, even destroying the afterlives associated with those realms. As the blast and shockwave destroyed him, Naoto screamed out, "DAMN YOU, DR. NEFARIOUS! DAMN YOU AND YOUR HATRED FOR ORGANIC LIFE!" as he was destroyed.
Back inside the Deplanetizer Sigma, Dr. Nefarious was cackling with evil laughter. "HAAAA HAHAHAHAHA! I CAN ONLY IMAGINE THE LOOKS OF ANGER, DISBELIEF, CONFUSION, AND DESPAIR ON ALL THOSE SQUISHIES BEFORE THEIR ENTIRE PLANET WAS DESTROYED!" he laughed out.
