I am a former soldier in the Demon King's army.

　Without knowing my birth, I was mixed in with the demon race even though I was of the human race.
　In other words, the army in front of me now is the enemy camp now, but it was once my old home.

''Knockers!　I can only imagine your outrage!　But in the spirit of comradeship, we must compromise.　.... hmm?　What's that?

　They rushed into the Demon King's army camp.
　Is it an advance party or something else, but it's not that big.

　If you're serious about retaking the mine, you'll need at least ten times as many as this one, right?
　From that point on, it could be surmised that the Demon King's army had no intention of war.

''Ni, it's a human!　It's a human adventurer!
''Return fire!　Attack magic all at once!
'Wait!　We don't have permission to engage........?

　It's a mess, but in the confusion, the demons fired their attack magic.
　We have to get rid of the enemy, the human adventurers.

　I'm going to have to get rid of the enemy adventurers, and that enemy adventurer is me.

　I'm sure that they are the lowest class of attack magic shot by a mere mortal, but if they all shoot at the same time, it is inevitable that they will be extinguished to death.

　So I took a defensive action.
　With the sword wrapped in aura, I shoot down all the magic.

　This is a trick that I couldn't do in the past.

That many attacking spells in an instant...!
You're a f*cking savant...?　Class A adventurer...?
No, you're a brave one!
Don't be afraid, push it, push it!　Show us what the Demon King's Army is up to!

　The soldiers of the Demon King's Army are brave enough to take on the challenge.

　I would like to admire their spirit and spirit as former comrades, but....

''Wait!　Don't fight, don't fight!

　There was a man with a commanding officer's rank who tried his best to stop them.
　I want this guy too.

We have permission to mobilize on condition that we do not engage in battle!　Retreat!　Pull back!　If this situation escalates into an all-out conflict, this time the face of the Demon King's army will be put to shame...!
Rizzeto, Rizzeto...!
Human adventurer!　Our intention is not to engage!　And he returned promptly!　...If you insist, you will enjoy the skills of this dark mage, Lizete!　It's going to be very painful!　So please move away!
I know. I know what you're doing. I know what you're doing, and that's why I told you to calm down...
'Oh, I see........ .........I mean, how do you know my specialty magic?　And your name?　Huh?
It's me, Lysate.

　and put his face close to the other side's commander.
　Close enough to touch forehead to forehead.

'Hmm?　Huh?　Dariel?
Yes, it's your classmate Dariel.

　The dark mage of the Demon King's army, Rizeto, joined the army at the same time as me.
　He was blessed with magical talents and rose through the ranks and should now fit into the middle class.

''Are you really Dariel?
'Yes, I didn't expect to see you here again.

　Me and Lizette embrace each other with our whole bodies.
　The bond is still alive today as the cherry blossom of our synchronization.

'Thank God!　Ever since you were gone, the Demon King's Army has been completely helpless.
It's been quite a while, huh?

　Perhaps because of the joy of seeing him again, Lizet blabbed on about the movements of the Demon King's army even though she wasn't asked.

◆

...Is it really that bad?
The worst part is that I got a personal reprimand from the Demon King. Because of that, my stupid son's eyes started bleeding all the time.

　Calmly, I got into a conversation with Lizet.

　Ordinary soldiers surrounded us and listened curiously.

''A reprimand from the Demon King is like a death sentence for the Four Heavenly Kings. It is said that no one in history has ever been able to remain on the throne of the Four Heavenly Kings after being reprimanded twice.
'Stupid son, for the first time, right?　This means there's no more grace. We've been driven to the edge of the cliff.

　By the way, the 'stupid son' is Master Bashbursa, right?
　Is that fellow a common nickname in the Demon King's army?

'That stupid son. He really thought that he could surpass his predecessor, so he's furious at the stumbling block from the very beginning. Thanks to that, the entire Demon King's army is in chaos.
What does it have to do with you being here?
A little bit.

　Old friends with each other.
　Their tone of conversation was filled with a sense of ease.

You'll be able to see that the demon king has issued a notice that there's no need to meddle with the mine. Foolish son was going to raise his entire army to retake the mine, but he was prevented from doing so. It was a relief because he said he was going to kill all the rebels.
Then it's not a good idea for you to be here, is it?

　It means that you ignored the Demon King's orders.
　In the Demon King's army, that's an act worthy of extreme punishment.

I got the okay to do it.

　According to Rizzet's story, no matter how untouchable it was, it would not be righteous to leave the knockers who belonged to the demon race in defection.

　If they don't reconcile and resolve their differences, there's no way to know what effect it will have on the other subraces under the protection of the Demon King's army.
　Therefore, under the condition that there will never be a battle, this mobilization is said to be for the purpose of getting the knockers to return home.

''.........Lizet. You're one of those guys who have a lot to worry about.
''The sub-race is the backbone of the demon race. Without them, the Demon King's army can't survive. The current top management doesn't understand that, so we, the lowly ones, will have to run around!

　Yes, he was a mage who knew humanity.
　It was only because of men like him that the Demon King's Army was still okay.

''It's all your fault!
''Eh?''

　I don't know why he took it out on me.

''Because you're leaving the Demon King's army!　　If you had still stayed in the Demon King's army, things wouldn't have been so bad!
''Don't be ridiculous. I was just a lowly dark soldier, you know. How can you interfere with the top brass...
"You were the Fourth Assistant King!　That didn't work magic, but everyone had their eyes on it!
You told me you couldn't pass the test.
'It's ... it's a rivalry. You're a step ahead of your peers. They were all rivalries. The obvious flaw of not being able to use magic, you can't not attack it.
''You didn't like the fact that such an incompetent person had risen to the position of Assistant Four Heavenly King because he couldn't use magic, right?

　I was pretty hurt by what he said.
　But don't. It's all a distant memory.

You can't disobey the Four Heavenly Kings if you are fired by them. That's the extent of my position.
Have you spoken to Lady Granberza?
I'm not going to tell you.

　So they were both silent for a moment.

'So what have you been up to since then?　What have you been doing?
So I have a big announcement to make.
Hmm?
I was a human.
Hmm?

　I told my old friend about the events so far.

　After being expelled from the Demon King's army, I wandered around unsuccessfully and ended up in the village of the human race.
　There he underwent a guild registration ceremony and was found to be a human.

　As expected, there's no point in keeping it a secret, even from an old friend.
　I told them without hiding it.

''Seriously...!　They told me you were an orphan, but...!　I thought you were Granberza's illegitimate son...?
Hmm?　Did they think of you that way?
"But I didn't expect a human race...?　That's why they can't use magic, isn't it? I understand...

　Thank you for convincing me.

So what are you going to do about it?　Could it be that you're planning to fight the Demon King's army as a human race...?
I'm not in the mood for this.

　Even if our races are different, I've spent the first half of my life as a demon race.
　I have ties and fondness for them.

　I can't hate them as an enemy now.

　The same is true for the human race, which is now my true camp.

I'm not going to be able to say that I'm not the only one. Now I want to work for them. Of course, this is as long as we don't avenge our former benefactors...

　So.
　I finally reached out to him today, so let's get down to business.

"Rizzet. I'm the one who caused the Knockers to defect.
I know.

　As expected of my friend, you have a good idea.

Of course, it's fundamentally the fault of the current Four Heavenly Kings who pressured the knockers. But even so, I don't want to do anything to harm the Demon King's army.

　So..........

　I suggested to Lizet.

'Why don't you guys buy mithril from the human race?'
What?
