With a battering sound, a red liquid is splattered on the ground.
　My right arm is gone, and my right half of my body is light. I feel a lukewarm breeze blowing through the hole in my chest.
　The sensation of pain was lost, and all that remained was the sensation that my core was freezing every second.

"A world without conflict?　...... You really thought that was what you were thinking about. You've come from a different world and you want to save this world?　Didn't you think it was presumptuous?
''Hahaha!　That's a masterpiece, Amatsu. You're the only person who fought with that kind of goal in mind.
'I think you should dream in your sleep, don't you?'

　Ryusas is laughing.
　Dionysus is laughing.
　Lucifina is laughing.
　My friends are laughing.

　--I've seen a lot of crying.

　I saw people who came into this world hurting and suffering and grieving.
　They gave me a reason to live when I was swept away.
　There were people who made me believe that if we fought together, we could accomplish anything.

I believed in .......

　So, so, so, so.
　So, I wanted to help.
　I thought how nice it would be if I could turn all those crying faces into smiles.
　And that's why I thought it would be nice.

I decided I was going to be a hero. I'm the first one who's done that in my life.

　Liuzas is sneering.
　Dionysus is sneering.
　Lucifina is laughing.

You must have a head on your shoulders to still be able to say such a thing after all this time.　That's disgusting.
You're not a hero. You don't deserve it. ...... too late for everything!
You're really funny, aren't you, Amatsu? You're really delightful, Mr. Matsu, to keep me amused until the very end.

　--They're laughing at me.

"It was all a lie, of course!"

　I heard the sound of something cracking.

''I got enough magic for my needs. Lucifina, clean up the rest of the debris over there.
So, Amatsu. Now go to sleep and dream all you want.

"Goodbye to the hero, Amatsu."

　I'm going to be the one who is cowering on the ground, Lucifina swings the "Tenri Sword" at me.
　A moment later, the magic power is amplified and an extreme slash is unleashed.

''----''

　Lucifina's gasp and jumped to the side.
　Immediately after, a small-scale explosion shook the room.

''There's still room for that--''

　I didn't understand what had happened.
　Just for that one moment, I was driven by an urge that rose up from within.

　Running.
　Kicking Liuzas, who was distracted by the explosion, I kicked him away and retrieved his slashed off arm.
　He adds it to his mouth like a dog.

　From there, the world seemed to move slowly from there on out.

''Luzivigaaaaaaaah!''

　An ugly exclamation. Lucifina's face widens as her eyes widen. The sword is swung off. The vision on the right side darkens. The outstretched arm pierces the armor. A warm sensation that scrapes through flesh and blood. It's gentle and lukewarm, like being immersed in lukewarm water. That's probably why I was laughing.

　--falling.

　I'm falling out of the demon king's castle with Lucifina.　
　Falling.

　----.
　--------.
　---------- ------.
　-------- ------------------------.

Ah, ............?

　I came to myself with a faint moan.
　I was still alive, even though I had fallen from the Demon King's Castle.
　When I woke up using my left hand, which was slippery with blood, I found Lucifina lying on the floor beside me, covered in blood.
　A great deal of blood flowed from the pierced chest, and both arms and legs were bent in a different direction.

"Hey ...... Lucifina.
I'm an amateur... .........

　Unconsciously, I reach inside my pocketbook.

'It's me, ......, and I loved you guys.

　I'd never had an existence that seemed so precious to me.
　The feel of cold steel.

That's why we've been fighting together for so long.

　I was able to get through any hard battle.　
　My core is cold, but my wet hands are so warm.

'And yet,'

　A series of wet sounds.
　A small, guttural, gurgling sound, as if it were crushing a tomato.

'-- how could you betray me?

　No answer.

'Why won't you answer me?'

　No answer.

"Hey, hey. Answer me.

　The thing that was Lucifina in front of me, the thing that was Lucifina, doesn't answer any more.
　Lucifina's blood is sticky on the knife held in her left hand.

'Oh, right. I killed ......?

　I wanted to protect the one thing that mattered most, even if it meant being a hero.
　He tried to kill me, and he was the worst traitor of all.

"...Ha.

　You tried to kill me, but Lucifina doesn't answer anymore.

'Haha,'

　That was annoying, unforgivable, funny, funny, sad, and fun.

''Hahahahahahahahahaha!''

　I straddled Lucifina and swung the knife down repeatedly.
　Many times until the laughter rising from the depths of my heart subsided.
　I'm not sure how many times I'll be able to do that until the sickening liquid that runs down my cheek stops.

　How many times did I swing it down?

"-- What are you doing,

　Amidst the stench of choking blood, I turned to hear a voice from behind me.
　A group of werewolf species (war wolves) were looking at me with a stunned expression.

'Amatsu ......-dono. Isn't that ...... Lucifina-dono, ......?　Why would you do such a thing: ......

　With a plop, a drop of blood fell from the blade of the knife held in my left hand.
　I realize that my facial muscles have gone mad and a distorted smile is sticking to my face.
　I realized belatedly how others would judge me now if they saw me.

'Wait. It's not, this is.

　Among the werewolf species staring at him with a stunned expression, he notices a familiar figure.
　The bespectacled werewolf species is a man who could be called a war buddy that they once fought together.

"Well, Merwin. This is .......
Everybody get ready!　It's not "Heroic Amatsu"!　It's a fake!
Where's ......?

　I don't understand Merwyn's cry.
　I was about to ask him what he was saying - and I noticed the frustration on Merwyn's face.
　His eyes, calling out to his confused companion, seemed to say, "Why are you alive?

'Oh ...... you, too, are you ......?　Hey, Merwin ......?

　I didn't want to believe it, so I approached them with a drawn-out smile.
　I felt someone scream with a hiss.

'What's the matter!　What's wrong with you!''

　With a clattering sound, several knights came from behind Merwin and the others.
　The knights of the kingdom opened their eyes when they saw me, covered in blood, then turned their gaze to Lucifina, who was lying in shreds.

''Luci...... Fina......?''
It's a lie. ...... Why?

　The knights' gazes turn to the knife I'm holding.

'Oh, I'm ......'
''--That man is a demon tribe that took the form of Amatsu-san!　He was laughing and stabbing Lucifina-san to death!

　Merwin shouted as he interrupted my words.
　The other werewolf species agree with him, and gradually the knights begin to point their swords at us.

''Merwin. You, too, are betraying me: ......
"Fake. ......!　What are you talking about!!!
'What are you ......, what do you guys want ......?'

　A knight and a werewolf species creeping up on me.
　My half-blown vision flickers and flashes.
　The gurgling sensation that bubbles up and I'm ----



　The next time I opened my eyes, all around me was quiet.
　The right half of my body, without my right arm, was light, and the left half of my body, which was grasping at what was instead heavy.
　I looked over and saw that I was holding something that looked like a ball.
　Countless threads stretched out from the ball, and the threads were entangled in my left hand.
　Every time I moved my arm, red liquid dripped from the ball in a flurry.

'----'

　In his hand was Merwin's head.
　When he looked around, he saw countless corpses lying around.

''Oh, I did it?''

　Somehow, I thought I heard Merwyn shouting.
　I was only invited by Lucifina and the others, I'm not the only one who betrayed them, I'll tell you everything, help me.
　I think I heard him say something like that.

'Hey. Did you guys betray me too?

　Ogres, cathedral knights, selectors, imperial sorcerers, demons, and demons.
　Before I knew it, the people who should have been fighting each other were surrounding me in harmony.
　When I paid attention to the corpses, I found that there were apparently more than just knights and werewolf species mixed in with them.
　Unconsciously, they seemed to have killed all those who attacked them.

'Don't move!　Are you ...... really an 'Amatsu'?"

　One of the selectmen asks me about that.

'Oh, yes. I'm--

　And even sooner than that, the magic descended on me.

''Wha?　Hey, hey, what are you doing!

　I can hear the selectors guffawing and shouting.
　The oddly wide-eyed imperial sorcerer is shooting sorcery at me, one after another.
　He held his left hand in front of him and blocked the attacks with his magic shield.

''That's not Amatsu-san!　Mr. Dionysus just called me to tell me they got a fake!　All of you, follow me!

　A cry comes from the demons.

"Everyone follow my demons!
We can't let this brave imitator live!

　A shout goes up from the Seido Knights.

　Starting with that, the people who have been surrounding me without a second thought are rushing in.
　Merwin's words, clearly evident by the unnatural movement of the surroundings.
　The people who betrayed me are planning to kill me.

'All right. ...... we get it.

　--The moment he realized this, Hero (Amatsu) was completely broken.

◇

I'm going to kill all the people who betrayed me.

　Screaming that, killing all those who stood in his way, Amatsu (...) tried to leave the battlefield.
　All that remained on the battlefield where he disappeared was a great number of dead bodies.

　Without knowing where he was or where he was going, he ran, ran, ran - his consciousness was cut off, as if to turn off the power.

◇

　The next time he woke up, Amatsu was being protected by a girl named Idler.
　The idler had healed Amatsu, who was badly injured all over his body, and carried him to an unpopular place.

I'm a genius, but there's nothing I can do about my right eye that's completely smashed up. It's a pity, but there's nothing I can do about it. The wound in my eye was up to the brain.　You didn't wake up for a month, you know. I thought you weren't going to make it.

　The idler spoke eloquently about many things to the silent Amatsu.

　In the past month, the world has been in an uproar over the actions of the hero, Amatsu.
　There are many rumors that he was turned by the demon tribe, that he was a pawn of the "Fallen Light God" Hadeer, that he went mad in battle, that he planned to betray the humans from the start, and that he was planning to destroy the world after all.

　The Demon King's army, which had been drastically reduced by repeated wars, took this opportunity to retreat completely to the Demon King's Castle.
　The allied armies of humans and subhumans have also suspended the war and are in a de facto truce.
　With the slaughter of Lucifina Emilior, the "Heavenly Knight", Merwin Johannes, the leader of the werewolf species, and many others, the Allied Forces have begun to defeat "Amatsu".
　The Demon King's Army is also searching every corner of the world to stop Amatsu from being strangled.

　The idler laughs and says, "It's amazing.

And then?　What did you save me for?

　Amatsu asked coldly.
　At the sound of his icy voice, Idler lost his frightened expression and uttered his thoughts as he smiled.

'I'm not your enemy. I just want you to kill Ortegia.

　Amatsu was the only person who had the potential to kill Ortegia.
　For that reason, Idler saved Amatsu.

...... I was betrayed by the people I trusted.
............?

　Ignoring Idler's words, Amatsu begins to speak in a blur.

'I came here to help everyone. I became a hero to make you smile. But those guys stomped on it and laughed at me.

............

'Was I so bad that they had to do this to me?　Was I really that bad of a person?

...... In the world, you're being touted as the worst kind of traitor, a betrayer of the world's hopes. The demon king's army treats you as a demon who slaughters his people.

　At Idler's answer, Amatsu sneered with a kutzutz.
　From the way Merwin spoke, it seemed that the powers of each country were complicit in the betrayal.
　The fact that the allied forces were trying to take care of Amatsu was undoubtedly because they had a hand in it.

'--I'm disappointed, world,'

　Amatsu muttered, looking heartily funny.

'The worst traitor of all. A demon who slaughters his friends. --oh, that's good.'

　Completely betray the Allied forces. Slaughters the demon king's army to the point of utter slaughter.
　Laying waste to the world, he is the worst kind of demon.

"With a guy like that, who doesn't deserve to be betrayed by his own people?

　So.

You will be what you want. I'll be the worst person in the world to be disliked, hated and betrayed by everyone.


　This is the day that our hero is disappointed in the world.
　He decides to destroy the world.

◇

　Amatsu's "individual" strength was unparalleled.
　In a one-on-one battle, there is no one in the world, aside from the Demon King, who would be able to defeat him.
　No strong man can reach Amatsu.

　However, no matter how powerful the individual was, that alone would not be enough to destroy everything.
　The reason why a powerful demon king has subordinates called "Four Heavenly Kings" and "Five Great Demon Generals" is because one person alone would not be able to resist the power of a swarm of humans or subhumans.
　If a large number of forces and separate forces such as the "Great Magic" and "Heavenly Knight" are combined, even a powerful individual can be defeated.
　This is proven by the previous demon king Sharnak, who was defeated by the power of the swarm.

　--And so Amatsu abandoned the idea of fighting it head on.

　He disappeared and disappeared from sight as he continued to wage guerrilla warfare.
　Before Amatsu's power, the damage to the Allied and Demon King's forces spread quickly.

　Or, he wouldn't have been able to get this far on his own.
　No matter how powerful they were, their opponents were many experts in the magic arts, no matter how powerful they were.
　They could have found him at some point and set up an all-out war.

　However, he had an idler.
　Her versatile magic arts would distract the enemy and keep them unconcerned about Amatsu's whereabouts.

''I will eventually kill the Demon King's army and all of Ortegia. For that, I will use you.
Yeah, that's fine. Why don't we all just look out for each other's interests? I'm ...... going to have to kill Ortega anyway to stay alive, so I'm going to have to put my trust in you. That's why I have no choice but to put my trust in you.

　Then, Amatsu killed all the remnants of the werewolf species.
　He half destroyed the Knights of the Holy Hall, killing all the selectors and destroying the adventurers.
　But no matter how much he rampaged through the world, Ryuzas did not show up.

...... have you found that man yet?
"You're not dead, but ...... you've disappeared completely. I'd be d*mned if I couldn't find you.
...... tch.
Don't hold your tongue: ...... I'm scared.

　Amatsu lays waste to the world like a gloom and doom.

　For example, the territory of the Empire.
　He ravages the imperial capital and burns villages.

''...... Why would someone as kind as you do this ......?''
'Gentle ......?　That's not true, Gash.

　The imperial aristocrat, Gash Rayford, kneels down and Amatsu sneers.

''--I'm the worst kind of scum.

　After cutting off Gash's head, Amatsu proceeded through the empire.
　The red-haired woman was at the end of killing all the soldiers who rushed in as if they didn't have the will to do so.

"Yo, Olivia. That's you, isn't it?　You used brainwashing magic to betray me.
Huh. I'm just...
I don't need excuses. I'll kill you anyway, whether you betrayed me or not.

　He stripped her of her claws, skin, and nerves, and still hung a healing spell on her to prevent her from dying.
　Amatsu turned Olivia into a living sculpture and displayed it in the imperial capital.


　For example, Schmerz, the holy city of the Church State.
　If you can't win in a fight, you burn the hidden cathedral knights and blow up the headquarters of the Order of Melt with magic.
　Amatsu laughs as he catches the two knights who tried to escape without their friends.

'It was George and Lily, wasn't it? Merwin mentioned your names, man.

　As they tried to defend themselves, Amatsu skewered them with a cross.
　He decorates it in the Holy City and laughs at them.
　On the way home, he slaughters a Sacerdotal knight who stands in his way, plucks out the "Magic Eye Knight" of the leader of the knights and puts it in his own eye.
　The field of vision on one side has returned to normal.

　With a crimson glow in one eye, Amatsu goes on.

　For example.
　For example.
　For example. ----.

◇

　The village of the demon tribe was turning red.

'What's the matter, Dionysus?'
......

　In both of Amatsu's hands, there are two heads.
　One is "Flame Demon" Bertooga.
　The other is Dionis's childhood friend, Shirley.

I killed your parents as well. I have only two hands, so I didn't bring my head with me.
----

　Dionis, who glared at him in annoyance, gave Amatsu an unexpected look.

''What. Even you would be shocked if someone killed your mate?''
They all thought I was going to kill them myself eventually.
............
'Take it all away and look down on me ......!　I hate that part of you so much!

　Dionis, swinging his sword, rushes in while screaming.
　The magic eye in Amatsu's right eye shines.
　It's not just a matter of time before you get to the point where you can see your own personal life.

Do you think you can win?　Small fry like you.

　And the two sides clashed.

　--On that day, the demon race was destroyed.

◇

　The first kingdom that could no longer sustain itself was the kingdom.
　The Knights, the Sorcerers, the Selectmen and the Kingdom have all lost their forces.
　The last remaining trump card, the "Great Sorcerer", Leusas Gilburn, disappeared and was never seen again.
　In the end, the king was publicly executed by Amatsu, and the king's people scattered to other countries.

It's all gone so clean, isn't it?

　In the empty royal capital, Idler murmured as if it were someone else's business.
　The king's capital, which was empty of people, was eerily quiet.

''I've killed all the pus, both king and nobles.
It's not just all pus, it's all gone, isn't it?

　Oh, and the idler points to the sky.

"I'm looking at it."

　In the eyes of Amatsu, who looked upward, I saw a magic power that stayed in the sky.
　You'll be able to see the same thing that belongs to Liuzas.

What do you want to do?

　A voice with an echo echo echoes through King's Landing.

'-I want to be the worst thing in the world, destroying the world.

　In response to Ryuza's question, Amatsu replied with boredom.

If you want ...... revenge, why don't you just go after us?
'You didn't hear?　I'm going to destroy the world. What's the point of taking revenge on an individual?　Well, I'm going to kill you.
...... Before, your light was so blindingly bright that it was an eyesore. But now you're finally going to be able to see it from the front.
Huh?

　Liuzas's voice grew more and more distant.
　In the midst of that, the last words were heard clearly.

''--You'll be killed by me.''

　At those words, Amatsu spilled tears and laughed until his throat was hoarse.
　Then he returned to his expressionless face and left the kingdom at a fast pace.

◇

　He killed humans, sub-humans, demons, and demons in large numbers.
　He killed all of them and was called a demon, and yet Amatsu still laughed.

　"Perhaps he was judged unworthy of being a brave man, but the 'proof of bravery' gradually faded and his strength weakened.
　Amatsu continued to kill them without regard to the fact that his body was gradually being wounded and deteriorated by the rapid magic power.
　When Ryusas attacked, Amatsu used the idler as a shield to survive.
　Betraying everything, Amatsu still continued to laugh.

◇

　And so.
　The whole country collapsed.
　The survivors fled into the forest.

''Hahahahahahahahahaha!''

　The trees roared and burned.
　Blocking the escape of the people who fled into the forest, Amatsu leisurely proceeded.

　--I saw a lot of crying faces.

'Finally, we're here.'

　-- hurt a lot of people and made me shed a tear.

"I'm a disgusting piece of garbage.

　--the worst thing anyone can hate.

'That's why ...... you guys betrayed me. You were right to try to kill me.

　--It was the only way to save the world.

Hey, you know. Lucifina. It's all my fault, isn't it?

　That's why you're a victim.
　It's my fault they killed you like that, you know?

Don't you think you'd feel the same way?

　In response to that question, what came back was gravity pouring down from the sky.
　The gravity shaped by magic power crushed the flames that were about to burn the forest to the ground, crushing every tree and extinguishing them in the blink of an eye.
　Everything but the ash tree, which had formed a shield with magical power, was crushed, and a large portion of the forest had been turned into flat land.

'----'

　The last person to stand in the way was a single demon race.
　A girl with long silver hair swinging and a strong will to fight in her golden eyes.
　Although she has a small body, the magical power she possesses is extraordinary.
　The demon tribe, whose mighty power she had clashed with many times in previous battles, was an acquaintance of hers.

I'm not going to be able to get it right. ...... and

　From afar, a tremendous magical power condensed to the size of a shell pours down.
　It penetrates the shield of magical power and blows Amatsu's body backwards.

''Finally, you've come out too, Liuzas ugh.　

　A red-haired sorcerer stands far away from Amatsu, who is laughing with his magic eye glowing, and a single red-haired sorcerer stands in the distance.
　"The Great Magician, Leuzas Gilburn.
　The pride of humans, the last trump card.

"The trump card of a human and demon tribe is showing up at once, that's quite a big deal, isn't it? What is the matter with you?
"...... I'm going to kill you and end it all today.

　The girl replied quietly to the impatient Amatsu, who was smiling impatiently.
　The red lotus magic eye gleamed in both of her eyes.
　It's a much higher level object than the magic eye that Amatsu has.

''Yeah, that's right. I'm sure you're not the only one. Thank you, demon race.
----
But why did you help me?
Because you didn't kill me. ......!

　Twin eyes, tinged with intense hatred, stare at Amatsu.
　But at the same time, a forlorn color floats in the air, wavering like an unresolved issue.

'I knew you were fighting for peace. I knew that you had been summoned to this world from another world to fight for years.
............
"So ...... when you put away your blade in front of me, your enemy, without killing me!　I would be ...... with you!

　The words never came out from there.

''If you are ...... with me, what do you say, demon tribe?''
It was just a mistake, too. You're a laughing, murderous monster.

　The world froze at the spirit that the girl radiated.
　That spirit that could rival even a "hero" made Amatsu laugh with his canine teeth bared.

It's not a good idea. I'm going to kill you and save the world. And I'll become a hero!

　At the same time as Ryuzas's voice echoed, a tremendous magical power erupted in the distance.
　It was incomparably more powerful than the previous Liuzas.

''Ah, I see. So the reason you were running around was to prepare your hand to kill me?''

　The girl's eyes turned to Amatsu, who was laughing at her as if she were someone else.

"It's Amatsu the hero. I'm going to kill you and put an end to all this.
No, you're not. No, I'm not the hero, Amatsu.
If you're ......, then what the hell are you?

　The girl asked.

I am the guy who wants to destroy the world. And you are the "heroes" who want to save the world. Well, then, I guess that's what I'm supposed to call myself.

　With a fearless smile, Amatsu replied.


"---- 'Demon King' and..."


　The girl smiled sarcastically at those words.

Perhaps you do have a better name for it.

Yeah, that's right!　I'm the worst kind of person who could ruin the world!

I'm...


　With those words, the girl took her name.
　Oddly enough, just like at that Demon King's Castle.

"--Elphiszak Gildegard.

　Her gray-tinted hair swayed in the fierce wind.
　The red and black odd eyes twisted into the shape of a crescent moon-like smile.
　Covering its body, it flipped a jet-black robe dyed red with blood.


"Demon King Amatsu."


　And so the end begins.






　--Now, let's start the final revenge.






The Tale of Revenge of the Demon King" is complete.
