The Rasperda Fortress was the largest fortress in the world.

　It was located on the border between human and demon territory, and was built at the intersection of the border and the line that connects the strongholds of the two camps in a straight line.
　Because of its location, it was the most important base of operations for the battle between humans and demons, and thus the huge fortress was built.
　At the end of the war, it was reconstructed and grew to an unparalleled size, but today, that history is over.

　The Rasperda Fortress has evaporated and disappeared.
　It was consumed by a conflagration so great that it engulfed the world's largest fortress in an instant.

　Even though it was piled up with the finest stone and covered with multiple layers of defensive magic, it couldn't withstand it for an instant, crossing the boiling point and returning to nothingness.

　The soldiers who escaped from the fortress after receiving an urgent order from the Four Heavenly Kings witnessed the scene.
''A horrifying fire engulfed the fortress and extinguished it''....

◆

"...why are you alive?　We?

　The current Four Heavenly Kings were scattered like wreckage after everything was too cleanly gone to be called a burned-out area.
　They were all safe and sound in their five bodies.

　Even though they were definitely within the area of effect of the extreme flames released by Inferno.
　No creature could survive while bathed in the super-high heat that even vaporized the fortress.
　Then why were they able to survive?



　A boy of white light descended from the heavens.
　There is no way that Ida, who can manipulate space, would be able to float in the air.

'It was a horrible evil flame. I'm sure you'll be able to find a way to make it work. I didn't expect it to be this tremendous.''
''You........you're the one who protected us.......?

　Bezelia could no longer avoid paying her respects to the boy.
　He called himself a great man who existed hundreds of years ago. The caution paid to such an outlandish opponent can't be dispelled in front of the competence shown in person.

I was so busy minimizing the power of his fire that I couldn't pay attention to anything else. I'm not sure I've ever been able to get away with it. It's disappointing to have existed for a few hundred years.
''Then I knew it was still........?''

　Bezelia shuddered.
　She wondered if this boy was really the Ida of 'Heaven and Earth' who left behind a brilliant and heroic name in the history of the demon race.

''Even if it distorts and ruptures space. ''That fire jumped over and tried to consume everything. In the end, the damage would have been more widespread if it hadn't been suppressed with pure magical pressure. ........Terrifying. A truly terrifying flame.

　When I was told, it occurred to Bezelia too.
　The heat is so great that the great architecture of the fortress will evaporate without a trace. Normally, the damage would not be confined to the fortress alone, but would have to spread to the surrounding area dozens of times.

　However, the reason why the fortress only disappeared neatly is because someone desperately fought back to make it so.

''Because of that, I've used up most of my magic power.......I can't fulfill the mission given to me by the Demon Lord with this.

　That's not all.
　The white boy had been exposed to the extreme heat of the flames and was disfigured to the point of disfigurement.

　Both of his hands and feet were burned out and burned out, and his cross-section was charred to black.
　Every surface of its body had been burned by the heat, and there was no trace of the cool, refreshing aspect of its original appearance.

''Even after turning like this, you're still trying to protect the Demon Domain...?

　If Ida hadn't suppressed the flaming heat, I don't know what percentage of the Demon Domain would have been gouged out by the burning heat.
　That's how tremendous the hellfire was.

''No, not only that, even us...?　What a pity that we, who should be standing on the frontline of the defense of the demon race, are so disappointing...?
"It wasn't me who did that.
What?

　While Ida and Bezellia were talking.
　Granvaza was on his knees, breathing hard.
　He was supported from both sides by Droyer and Zebiantes, who were supporting him between them.

'Lady Granbaza!　Be careful!
You can't die!

　Glamberza was half-dead from the original Inferno attack.
　On top of that, he was obviously unusually drained.
　His complexion was pale and he was emitting sticky sweat from his entire body.

''Ka........Don't kill me without permission......!　I'm not going to die until I see Gran standing on her own.......!

　But he was fearless.
　The strongest of the four heavenly kings who would also undoubtedly leave a legacy of heroism in history.
　His original stubbornness was different.

''You were the one who mitigated the flames of the inferno, weren't you?

'Heaven and Earth,' Ida said.
　Granberza replies while disturbing her breath.

''........Sorcery is a branch of magic that belongs to the fire attribute magic. It intertwines magic with the action of a person's mind to manifest an odd form of action.''

　Sometimes it works to twist even the laws of matter.
　The special magic that Granbaza positions as the ultimate profound magic, 'Ano Screaming Pyrotechnic Uninterrupted Flame Hell', also has a black flame added by the spellcraft that burns out the target even more than the normal flame heat.

It's not just a matter of time before you'll be able to get your hands on it. It's a magic that can come in contact with the flickering of people's hearts. That red cloak's last magic is its ultimate type...?
''As expected of the flame wizard Glamberza, who is known as the ancient and modern warrior. I'm sure you'll be able to find out more about this. You're not going to be able to get your hands on any of them. You've been able to resist his magic.

　The extreme flame that was released at the expense of one of his companions' souls.
　Ida's spatial manipulation alone was not enough to prevent it from happening.
　He managed to suppress the burning heat of the souls by using the spellcasting techniques that Granbaza was accustomed to in order to master the 'Anosu Jiaozo Jiaozo Immersion Flame Hell'.

　Even if Ida hadn't been present here, or even if Granbaza hadn't been present, they wouldn't have been able to suppress the damage to this extent.
　The fact that the epicenter of the bombing was on the border between human and demon territory must have led to a catastrophe that would have affected the national governments of both sides.

The Red Cloak's magic is truly terrifying. It's definitely the work of the Doris Megian.
'Yes, that's right!　What the hell is going on here!

　Zebiantes screamed.

'You don't understand everything!　Ida-san is a demon race that was around hundreds of years ago, right?　How is that possible now!　He just showed up as a cute little shorty!
Don't be a little boy.
"And who is that red cape?　He's the one I don't understand the most!　You think he's dead and then he's alive, and then he changes like a different person in the middle!
Calm down, Zebiantes!　You are unseemly as the Four Heavenly Kings.......?

　Although Droyer tried desperately to restrain her, in vain, Zebiantes' madness only increased.
　The white Ida, perhaps unable to watch, spoke with a sigh.

''........The Demon Lord has two worlds.''
Two worlds?
'Both worlds are to be the peace of the soul. On one side are great souls. In the other, sinful souls. I and the mass of people called the Inferno came from different worlds.

　The souls that enter those worlds are sorted out of a certain class.
　The Four Heavenly Kings.
　Those who are recognized as the greatest wizards of the demon tribe, and who have achieved more commendable achievements.
　When they have completed their duties in this world, they will be welcomed into the eternal paradise.

That world is Valhalla. Only those who have done unparalleled feats of valour during their lives will be welcomed into that world. Take Granvasa, for example. Your fame resounds throughout the land. You will surely be in Valhalla when you die.
'What?　So I'm going to...?
No, not you.

　For some reason, Droyer pulled back Zebiantes, who was shyly trying to stand.

''In contrast, a world where sinners who have defiled their dignity as human beings in life fall........ Hell. That's where the Inferno came from.
''Then, after all.......the horrible legend of Drismegian of 'Sahi' is true. If that was really what was done, then yes, it was worthy of going to hell.

　It wasn't just from exhaustion or injury that Glambarza's expression turned into one that bit down on a bitter worm.

''Granberza-sama...!　This 'Sahui' person...?
You young people are ignorant of this. In the long history of the Demon Race, there were great men like Lord Ida of Heaven and Earth, but there were also sinners who were abhorrent to talk about. Such people were forbidden to even write them down in the history books and were forgotten. They were only told by the few in charge.

　Such sinners have escaped from hell and returned to this world.
　They are planning something, and they are moving around.

They are not bound to their bodies once they have fallen into hell. The souls of those who have fallen to hell are not bound to their bodies, but they form one body.

　That's what the inferno is all about.

'Master Ida!　What are they planning to do?
Perhaps revenge against the Demon Lord who d*mned them to hell.... What a foolish thing to do! If there are thousands of sinners, they can't stand against the Demon King.

　Before I knew it, Ida's burnt-out body in "Heaven and Earth" had been regenerated and returned to normal.
　His entire body, a pure white boy figure without a single blemish.
　Was the soul welcomed by Valhalla and freed from the body, no matter how old or damaged it was?

'Nevertheless, the demon king sent me from Valhalla to prevent the evil soul that had escaped from hell from disturbing this world. Even though they have fallen into hell, those souls are also first-class in their abilities. They were lined up with the strongest of the human race in their lifetime.

　Now the Ida of 'Heaven and Earth' has been completely restored and turns its gaze to the distance.
　The destination of her gaze is human territory.

''The inferno got away from me in that extreme flame fever. That was only for a short time. I'm sure I'll hunt them down to the bitter end and catch them for sure.
Then we'll help you...?
Four Heavenly Kings of this world. You are to complete your mission. Your job is to fight off the heroes and protect the Demon King. That's what I did when I was alive.

　And now, he goes as an existence that transcends even the living.

''Inferno must have once again gone into hiding in human territory, where the Demon King's eyes are difficult to reach. But as long as this I have descended, it doesn't matter where I escape to, I will hunt it down. I will definitely hunt him down.

The Ida of Tenchi enters human territory.
　With the hawkishness of someone from the past, he doesn't care what kind of confusion it causes.
