After the Hagiwara family's repair shop went out of business, they found an old, broken game console from his childhood while packing up.
On a whim, he decided to fix it.
"...A virtual pet?"
It was not only an old-fashioned black-and-white pixel game, but also an idle game with hardly any interaction.
Hagiwara scratched his head. He didn't remember this being the game he'd played.
Oh well, he'd fixed it, so he might as well play.
Unexpectedly addictive. Whenever Hagiwara had a free moment, he had to check in on his little pet.
Until one day, a strange electronic voice suddenly appeared in his head.
[Zzzzt... I am... zzzzt... the System... zzzzt... You shall address me as the Demon King...!]
Hagiwara: ...Huh?
He thought he'd heard some weird static. Was this System malfunctioning?

The newly appointed Demon King wants to accomplish something every Demon King in history has dreamed of doing:
Conquer the human world.
At present, His Majesty the Demon King is troubled because he can't transmigrate through the barrier set up by the gods.
Then inspiration strikes. He sends a game console into the human world, only for his mission to fail before it even begins: the console hits the ground and breaks.
Just as he's wondering what to do, someone actually fixes the console!
Wonderful! The first step toward conquering the human world will be to start with this human!
He'll make him his first servant, just this once!
But this servant is way too annoying! Why does he keep poking him?! So disrespectful to the Demon King!
Huh...? Why has his consciousness suddenly entered the body of this human servant?!
How is he supposed to handle this?
After flailing around, the Demon King suddenly has an idea and strikes what he thinks is an incredibly cool pose.
"Hmph, foolish human! Listen well! I am the Ultimate System, ruler of countless torrents of data! Since you are my first servant, I shall magnanimously allow you to address me as 'His Majesty the Demon King'...!"
He has such presence. He's so cool! Scared now, human? Heh heh heh
(Silence) (Quiet) (Awkward)
...Are you going to say something or not?!
