The Hero's party has assembled and sets off for the Demon Realm to defeat the Demon King.
The entire human world is filled with cheers and laughter. Everyone believes the Hero's party will surely defeat the Demon King and bring peace to humanity.
Meanwhile, in the Demon Realm...
The Demon King has fled, leaving behind his crown and an empty throne.
In ordinary times, every demon would probably fight to become the next Demon King.
But these are unusual times, and no one wants to risk their life by forcing themselves into the position.
What if the previous Demon King comes back? Wouldn't the new one just be a scapegoat?
The demons, who uphold the fine virtue of yielding to one another, suddenly think of the fallen saint who was driven out by humanity.
The fallen saint helped a commoner girl kill the nobleman who assaulted her.
The demons say: "He heard a few words and dared to kill someone without a second thought. He's a natural Demon King!"
The fallen saint was appointed by the kingdom to rescue people trapped in the Lost Forest, where he slew countless fallen creatures that threatened humanity.
The demons say: "He's a bloodthirsty killer with thousands of lives on his hands, at the very least. He's a perfect fit for Demon King!"
The fallen saint subdued an ancient evil dragon and defeated Gluttony, one of the Seven Deadly Sins, in the Demon Realm.
The demons grit their teeth and say: "He's incredibly powerful and has a one-of-a-kind, super-cool mount. He meets the requirements to be Demon King."
The fallen saint was driven out by the church in the name of evil, and everyone turned against him.
The demons say: "He's infamous, and absolutely at odds with the church. If he isn't the Demon King, then who is?!"
Two months after the fallen saint Anders was exiled from the human world, the demonfolk praise his wickedness while humans despise him. Surrounded by demons, he is crowned Demon King.
The ever-kind Anders: "Huh? Me?"
On his first day as Demon King, Anders makes every demon sign a contract of obedience. Then... all the demons start studying.
When the Hero's party arrives to defeat the Demon King...
"Hello. The Demon King's appointments are booked through the second half of the year. Please get in line in advance if you'd like to see him." The Demon General named Envy is elegant and courteous. "You're a VIP, so I can move you up a little if you make an appointment. How does eight months from now sound?"
The Hero, who is also the previous Demon King and the ancient evil dragon summoned as the current Demon King's familiar: ?
