The Betrayed Hero Who Was Reincarnated As The Strongest Demon Lord

I'm back, Your Majesty.

During the audience, a skull swordsman clad in an old-fashioned armor appeared.

He was the Demon Army Chief Regal with the title of "The Immortal King (Lord Undead)".

He had traveled to the human world to search for the currently missing Beast Emperor Zeggert.

''Unfortunately, we were unable to track down Zegert and the others. I have had my handlers continue to search for them, but I have returned in this manner for a timely report.

Good job, Regal.

I nodded to myself on the throne.

"By the way...

Regal's gaze turned to the demon tribe standing next to me.

To a beautiful boy with silver hair and brown skin.

''Ah, you haven't been introduced to me yet. The newly appointed 'Polar Magic (Master)' Judah Lugis as the head of the Demon Army.

Oh, you're a senior undead. Nice to meet you, Regal.

Judah smiles and waves to Regal.

"Judas...?　No way, a member of the most ancient demon race...

Regal groaned.

''None of the previous Demon Kings could have obeyed him alone...''

'This generation of Demon King-kun is an odd one, you know. I was curious.

Judah laughs mischievously.

''For now, I'll help the Demon King's Army do their job.

He's a very capable fellow with many oddities. I hope you will join forces with me and serve the demon world.

I said to Regal and then to Judas.

'Yes, my king.'

"As long as they're not too keen on it.

Regal is grudgingly bowing his head and Judah is carefree as ever.

They are two people who are very different.

Suddenly, an intense chill that made me shiver all over ran through me.

At the same time, a red flash of light flashed outside the window.

"What the...?

I furrow my brow under my mask.

Beyond the horizon, a crimson pillar of light was rising up.

I was horrified.

My spine grew fierce.

There was something in that place.

Someone who radiates a tremendous sense of intimidation.

"Why is that thing in the demon world...?

Judah slightly raised his eyebrows.

''The 'Celestial High King (Divine Gear)-''

"You can't be that legendary...?

Regal groans.

You know, both of you?

'It's a weapon from the battle between Welfar and the Heavenly Army and the Army of the Brave.

Judah explained to me.

'You've seen it in my dreams, haven't you?'

Oh, and by the way...

After being told, I remembered clearly.

'But why would such a substitute be in the demon world?

You know what?　You might want to go check it out.

And Judas.

''If the performance is the same as it was in the past, the demons will definitely be slaughtered.

....!

I gulped.

"Do you know where it is?

When you're spewing so much magic, right?

Show me around.

I got up from my throne.

And.

My Demon Lord, there's a hint of...

Hey, I've got a really bad feeling about this.

Stella and Feria entered the audience room in succession.

This meant that the four Demon Army Chiefs were all here.

''It's like the 'Divine Principle'. A weapon of the heavenly army that has destroyed many demons in the past...

Me telling them both.

Well, this explanation was taken from Judas.

"Why would such a thing...

''We don't know why he appeared. In the age of mythology, Wölfer fought against three Divine Gears and did a lot of damage. But it did not result in their destruction.

Judah replied to Stella's murmur.

'The three bodies left the battle lines to repair their wounds. Velfer was eventually killed in the subsequent onslaught with the Heavenly Army and the Brave Army, and the remaining demons were defeated all the way to the demon world.

''Shouldn't we go check on the 'Celestial High King (Divine Gear)' to see what's going on?'''

Regal suggested.

'Well...'

If you want, I can do it. If necessary, I will destroy it.

And regal.

A visible fighting spirit erupted from his entire body.

''I know it is a worthy prey for my sword.

...you're just a fighter, aren't you?

I inwardly tsk.

'No, I'll go.'

The opponent seems to be a formidable foe.

Even for a demon army chief, it's not going to be a simple matter.

''Regal, along with Judah, will ask you to protect the castle. This could be a diversion, and to begin with, there are a total of three 'Tenso High King (Divine Gear)'. It's not guaranteed that they won't attack separately.

But I don't think the king himself is the one who should take it lightly.

I think it's reasonable in terms of strength. The Demon King is very strong.

Regal, who seemed to disagree, and Judah, who nodded casually.

It's a good idea to be prepared for a variety of magical attacks, such as camouflage, spatial mutation and mental interference. It's a good idea for you to be prepared, Demon King.

Okay, Judas. Will you come with me?

What, me too...?

Judas opened his eyes in surprise.

''It's ... a pain in the ass.''

How dare this guy act like he doesn't like me?

How dare you show your displeasure at the king's command?

Stella is breathing heavily.

"I was personally appointed by the Demon King...

It's still a loyal comment.

...I wish I could have gone with the Demon King.

Hmm?

'You're not mad at me because of the king's order, but more because of your personal feelings?

Judah laughs.

'Are you sulking because you weren't nominated or something?

It's just love!

And even Feria exclaimed with a happy face.

'Yi, suddenly, what do you say, both Judas and Feria!　I'm just trying to give you my opinion as a member of the, uh, inner circle...

"Uh........well, what is it? Speaking of 'Divine Gear', it's an ancient weapon created by the gods, right?　It's the quintessential stuff of magic. Doesn't that interest you, Judas?

I said to Judah to restore the air that seemed to derail me endlessly.

"For research purposes, you know.

....!

Judah's complexion changed.

'I see, that might be good. I'll have to accompany you.

I think I'm starting to understand how to get this guy to listen to me.

If this enemy is going to use a mental interference attack, shouldn't I be there?

Feria slid closer.

Muzzling, she pressed her lush breasts against me.

''Feria, attached to the Demon Lord again........''

Hmmm, jealousy?　I knew it.......love!

Yeah, yeah, that's why I said no!

To the teasing Feria, Stella's face turned bright red.

''Is it called love........?　I don't know.

Tweeting Regal.

If we don't, we're going to get sidetracked again.

Let's get our policies together.

I forced myself to get back to the topic at hand.

Me, Feria and Judah are going to investigate the enemy that looks like the 'Divine Gear'. Stella is to lead the Demon King's army on my behalf. I'm sure you'll be able to find out more about this. I would like to ask each of you to do the same.

Yes, sir.

Stella and Regal bowed reverently.

I got ready to leave the Demon King's Castle with Feria and Judah.

''Um........Demon King-sama....

Just as we were about to leave, Stella called out to me at the main gate.

'Hmm?'

Have a good day, sir.

Stella's eyes as she stared at me were slightly moistened.

''The opponent this time is a powerful enemy. Please take care of yourself........

Don't worry about it.

I stare at her through my mask.

'You know my power. It's probably the most powerful weapon in the Heavenly Army, and I'll be back soon to put it away. Take care of things while I'm away.

And then - I left with Judah and Feria.
