"The damn government focused on getting power back to 130 million people in the middle of the worst power blackout in human history where there's a large elderly population that is going to want heating/cooling and life saving medical care that requires this wonder thing called 'ELECTRICITY' over finding out how/why 12 people died/committed suicide(?)..."
Those god damned government leaders! How dare they prioritize health and safety of people that are still alive!
"The evil spirit that your friends and you has sealed will be free in a few years."
"His soul is blocked for now, somewhere inside your old world."
...Wait, what? What... the fuck? So... that monster spirit thingy that... he saw (mostly heard) for a few seconds is... back on Earth? Sealed away? And, what, he's going to wake up in Earth? How'd he get there? Why is he not in this new world the MC is in? This makes no god damn sense.
Can we get the manga were Earth militaries are pummeling the shit out of a knockoff Godzilla instead? Is it too much to ask to see a dragon or some monster get a tank cannon enema outside of GATE? Come on.
"Sadly... The evil spirit force your friends to commit suicide with his powers."
"Suicides? And I'm the responsable?"
And then John was a zombie Satoshi was the responsable.
"When I found at that your friend were dead, I decided to teleport you in this world to save you."
"This world was created by me and my goddess friends based on the game that you love so much."
...This goddess is so useless that she puts Aqua to shame. Why the fuck would you go through so much effort to teleport someone, and CREATE AN ENTIRE NEW WORLD, rather than just, I dunno, stopping that monster or teleporting him somewhere else on Earth? Or just up in heaven or where ever with the gods and giving him a quick peptalk, maybe wipe his memories, whatever, and send him back? I mean, I guess the excuse of "but she's a goddess, brah" might get bandied about, but so what? Why go through that hassle?
Also, the tired old trope of "we can't send you back because you died" can't even be used here - he didn't die, his friends did. So... even less reason to do so, then.
