The Background Character Becomes the King of All Ghosts Through Card Draws

Nanase Nanao was an ordinary passerby, 24 years old, and a top sales representative.

That is, until he was bound to a gacha System and ordered to become the King of a Hundred Demons. Otherwise, he would die on his 25th birthday.

To stay alive, Nanase Nanao decided to start pulling cards.

The card pool required real money, so he spent the maximum amount and earned the right to do a ten-pull.

His first pull was a seventeen-year-old genius sorcerer, a born Child of the Gods.

The other boy had white hair and blue eyes. At their first meeting, he hit Nanao with a whole package of cursed techniques, immobilized him, and tried to exorcise him. "Are you a Special Grade curse?"

Nanase Nanao: ? I'm just an ordinary person!

His second pull was the leader of the Star Religious Group, the strongest curse user of the era.

The other man had black hair and wore a Buddhist robe. With a kind expression, he had a monster on his left and another under his right hand. Smiling gently, he said, "The Lord of a Hundred Demons? That's easy. How many monkeys do I have to kill?"

Nanase Nanao: ? Are you the leader of a cult?

His third pull was the King of the Sheep, wielder of the strongest gravity.

The other boy had orange hair and blue eyes, was only fifteen, and stood proud and unyielding as he glared at Nanao. "You want me to be your subordinate? Have you even looked at yourself?"

Nanase Nanao: I don't know what I'm worth, but I do know you're only five foot three.

His fourth pull was a key executive in the Port Mafia, someone who showed no mercy.

The other man had black hair and narrow eyes, with a bandage over his left eye. Sitting on Nanao's broken sofa, he propped his chin on his hand and looked at him. "Lord of a Hundred Demons? I suppose I could do that, if you can entertain me. Then I might help you."

Nanase Nanao: What exactly do you mean by entertaining you?

Every one of the ten pulls was a peerless prodigy.

Every single one was a colossal headache.

The System proudly puffed out its chest. "Well? Was all that spending worth it?"

Nanase Nanao: Thanks for asking. Being a salesperson was already hard enough, and now I'm the nanny for ten people. System, can't you give me some normal people?!

Recently, a gloomy atmosphere had settled over Beika Town, and strange rumors were spreading everywhere.

Just as the Red and Black sides were locked in an absurdly fierce fight, a new force began to rise: the Grave of Monsters.

- Just as Gin was about to complete a mission, a white-haired, blue-eyed boy snatched his target first, grinning wildly and recklessly.

"This is my prey!"

- Just as KID stole the most famous jewel and was preparing to escape, a bandage-wearing boy with narrow eyes tilted his head beside him and asked curiously,

"What is that? Can I borrow it to play with?"

- Just as an FBI agent was about to detonate a bomb and die with the people from the organization, an orange-haired, blue-eyed boy crushed the bomb with one hand and said, utterly unapologetic,

"Please don't litter."

The entire Red and Black sides were toyed with, but they were helpless to do anything about it, because their opponent was incredibly powerful!

Nanase Nanao, the behind-the-scenes boss who kept a low profile despite all his accomplishments, had this to say:

"When I first took over as King of a Hundred Demons, I had no idea the job also involved managing tense relations with humans."

"But please, don't thank me too much. I'm just an ordinary pacifist!"

It definitely wasn't because they looked too idle, so he found them something to do!

A few notes before reading:

1. Nanase Nanao is a man. Why does a man have a woman's name? That's a little Easter egg in the story!

2. This is a story written to cater to the author's tastes, so it might not appeal to everyone. I hope you'll understand.

3. The pairings haven't been decided yet, so there are all kinds of pairings mixed together! Please read on only if you're okay with that!

4. The physics and professional knowledge in this story are all made up by the author. Don't think too hard, and come along with me to enjoy this beautiful world of a hundred demons!
