Demon King of Phantom Thief – a Betrayed Thief Stole the Stats and Skills of the Hero Party Then Reigned Over the World

It was before we embarked on a crusade against the Demon King.

I was surprised when I first heard it.

I thought I'd work for a little while, when I got to the Adventurer Guild.

"I've been waiting for you, Mr. Keith Aldberg. It's a quest from the kingdom!

The documents given to me by the guild's receptionist had a date and time to ascend the castle and the king's mark had been stamped.

Keith is just a bandit.

I'm not in the kind of position the king asks me for something.

Still, the king only asked for it, so Keith climbed the castle on time.

This is actually the trap, and maybe you'll be arrested like everyone else in the Aldberg Bandits.

I thought so, but the Adventurer Guild is a huge organization with thick pipes in every country on the continent.

Even one tiny bandit would develop into an international problem if it came to arresting him on account of his profession.

Of course, that's not why bandits can do whatever they want.

I mean just to use my experience as a bandit to contribute to my guild, and no other act of looting is permitted.

So the real bandits don't sign up for the guild.

A bandit who registers for the guild is one who no longer has company, like Keith, for example.

Or limited to those who have inflicted the great sin, etc., so much so that they have no choice but to seek refuge in the Alliance.

Even for that felony, no one who is wanted for murder can register for the guild.

By setting such rules, the Adventurer Guild remains in good shape.

I remember being stared at by Giroli when I showed my ID to the guard.

It says "Keith Aldberg [Bandit]" in large part, not in such a way as to be able to climb a castle.

Yet Keith was passed through until he saw.

He was kneeling on the carpet with his first fellow travelers to meet him.

"Raise your face."

Follow your voice, face up.

The king went down from the throne and looked around at each one's face.

"I'm still a chosen brave man, I have a good face" - the brave gelm.

"You're a warrior. Excellent physique. That's what I want from my army" - Warrior Zotto.

"It's a lot of magic. You'll be quite a user in time" - Meralda the Mage.

"You have a glowing, beautiful face. It's the face of the God-watched." - Cleric Marie.

"And you, bandit" - Bandit Keith.

The king told him to throw up.

"I don't know what the astrologer thinks, but you move the stars. You're a bad-eyed guy. To be clear, I don't like the rest. What about joining a line of Bandit Fu Issue Braves and more!

That's what I said, I stuck Wang Zheng on the carpet.

"But it is a lesson to determine the brave man and his companions in the divine trust to which the occupier was subjected. I'm not going to let you through until you bend it. Stand up for your country at best."

Then the king asked the party what he wanted at the dawn of the Demon King's Crusade.

Germ, Zotto, and Melarda get gold coins.

Marie made a donation to the Sanatorium.

Keith demanded the release of the Aldberg Bandits.

The king's brow moved tingly.

"How about you rebuild the filth you wiped from our country"

"Whatever...!

Keith lowered his head deeply just rubbing his forehead against the carpet.

"Fair enough. It is also a lesson to grant amnesty to the meritors of the crusade. Why don't we just do what you say?"

- The promise was betrayed.

………………

…………

……

Keith was in the castle backyard.

- [Scanning].

It is the talking room where the king is.

That path is drawn behind Keith's brain.

Two armed guards stood at the back gate of the castle.

Keith has already touched a guard who was paralyzed in a locker.

- [Disguise].

From the tip of your hands and feet, something tells you about Zawazawa.

Eventually it reached the center of the chest.

………………

Touch my face, it's not my usual feeling.

Keith no longer looked like Keith.

[One-eyed glasses of certainty] are gone.

[Disguise] In condition, it seems impossible to search for someone.

Keith walked out in front of the guard with dignity.

"Hey."

To Keith's appearance, the two guards looked suspicious.

"What's the matter, guard, what are you doing here..."

At that moment, Keith's body flipped.

Slap the knife into both necks at the same time and make them faint.

This is a move I've been able to use since I was a bandit.

"Well, have a good dream..."

So again [disguise] - Keith turned into the defeated guard.

Pick up the spear, plus [unlock] - the back door of the castle is opened.

Keith stepped on the carpet and entered the castle with dignity.

I don't even need to use [sneaky feet].

"It's quiet."

- [Signal perception].

Someone approaches me from the corner.

Keith stopped.

What came out was a beautiful woman with wings on her robe.

Keith puts up a spear and shows his heels aligned.

"Good night."

The woman has spoken.

"Ha. If you look at the window, you'll see the beautiful moon."

"You had a guard with poetry. The name."

It's Keith Aldberg.

Keith answered without cowardice.

"Keith, I'll remember that."

That's what I said, the woman has turned the corner and gone.

"I'll remember, huh?"

How many people in this castle will remember the name of Keith Aldberg, a member of the Brave Party.

Even a king in person is suspicious.

………………

Keith opened one room after another, confirming that there were no people in [Signal Detection].

The room you know is where you can sneak in at the [gate] of Alleyra as it is.

I don't know when I can use the castle again.

I'll be ready.

Numerous meeting rooms, halls, studies… Keith strolls through the castle at night, stopping by the different rooms.

That's how I finally got to the talking room on the third floor.

- [Audio enhancement].

"... but it's more than anything I could get rid of that sort of bandit. Bug spit runs to our brave party, such as bandits. There was nothing unpleasant about climbing the castle."

"You're right, Your Majesty. There was a fear that the brave men would hesitate to kill their fellow travellers, but they didn't seem to worry about it."

What you hear is two men talking.

"Well, how do you know that? The truth is, you may have missed it by deciding to kill him."

"A man like me can see if he can kill a person if he looks into his eyes. Except for the clergy, they were all of those with that quality. As much as I want my army to. And even if I missed it, I can't imagine anyone dealing with bandits who brag about defeating the Demon King."

"Sure, it is"

Keith opened the door when the king laughed.

"Who are you!?

In two majestic tunos, one eyeglass. Black cloak.

As soon as I saw Keith's face, they stood up.

The bottle on the table collapses, the liquor spills, it carpets and falls.

"This is to His Majesty the King, My Lord General."

Keith flashes his cape and finally gives a toast.

"Guards! Where are the guards!

"By guard, do you mean this?

- [Disguise].

Keith's appearance changes with cockroaches and turns into one of the guards.

"Or is this it?

- [Disguise].

"There was this one too."

- [Disguise].

"Then you monster!!

The general came brave, pulling out his sword and attacking him.

But on top of the booze, Keith lightly turns a blow into chaos.

- [Disease Theft].

When Keith slipped past the side of the general, the sword was already in Keith's possession.

"It's a great wave. Let me take this."

As he inserted his sword inside his cape, Keith grinned niggly.

"Hih!"

The general puts the king down and tries to escape from the room.

- [Locking].

Keith remembers, the key to the room closes all by itself.

The General desperately pulls or pushes the door but does not open it.

I noticed it, and I couldn't even be scared to put my hand on Thumbturn.

"Who is it!? What are you doing!? What's the purpose!?

The king falls back and hits the couch.

"I'm“ The Thief Demon King. "Keith Aldberg. I'm going to get His Majesty's important stuff from one end. Purpose is... is it innocent to say revenge?

"Aldberg...... no way that bandit......!?

"I didn't know you remembered, it was truly an honor and the ultimate"

In the moonlight of the window, the monocular glasses twinkle.

"His Majesty the King [governs] [strategies], His Excellency the General [directs] [tactics] Hey. You have good skills, among other things. Not so bad for intelligence to see the status"

"What are you talking about!?

The king shouted.

The General is still struggling desperately with the door.

"I'm talking about what His Majesty and His Excellency will be stealing tonight."

The two screams that went up in the late-night talking room were never heard by anyone.
