The black flames that enveloped Salamandra, the Flame Demon Beast.
　It is the result of the great magic released by the previous Four Heavenly Kings Granbaza.

　The Flame Demon Beast, which originally controlled the flames, was burned by the flames and suffered in agony.

''Amazing...!　What is that black flame...?
''I'm afraid to pee just looking at it...?

　Even Radie and Xeviantes, who are watching the battle, are afraid of the heat.

''That's the fire of hell controlled by the strongest four Heavenly Kings.

　Aranzir, the previous brave man who had retreated to the safety zone, said.
　He was breathing unevenly, mindlessly. He was in such a hurry to get away.

You can't get away with this," he said. It is a curse of indiscriminate condemnation that judges even the innocent as sinners. I don't understand it anymore.

''That's right. Once that black flame is consumed, regardless of its nature, it doesn't matter if it's flesh, wood, or iron, it will burn to ashes. Even the spirit by the curse...!

　That's why it's also sufficiently effective against Salamandra, the Fiery Demon Beast.
The Granbaza Ultimate Flame, which has the title of 'karma fire', will burn up even the same flame.

''You were the only one who could survive a decent exposure to that fire, Arantzill.

　Once the special attack was completed, Glamberza also dropped back to where Radey and the others were.

''I don't want to be eaten again, though. It's months until the after-effects of the curse's flames pass. It's been a hellish agony.''
That's why you were so desperate to get out of there.
"Complicated.

　However, the most astonishing thing was that the target was still not dead while being struck by the ultimate profoundness of the two most powerful people.

　The Flame Demon Beast Salamandra was still trying to get up despite being surrounded by black flames.
　Finally, it extinguished the black flames with a roar.

''How dare you........!　This is the power of a legendary demonic beast...!''
"Our innermost secrets do not allow us to survive...!　I'd like to think it's because I'm old and less powerful, but...!

　Even so, the Flame Demon Beast, burned in places, with painful lacerations carved into his abdomen and his movements were slow.

''The damage has been done enough. His strength has weakened and his movements have slowed down. I may be able to stop breathing in a few more minutes. The battle begins here!

　Under Radey's command, the surroundings are also inspired and their morale increases.
　This is the time to attack with a single mind.

'Arantzill-sama!　Lady Granberza!　I'd like to take the lead on this one!　Let the two of you finish the beast!
No, I can't!


　The two predecessors who showed the strength of the demon gods.
　However, their momentum was no longer there and they slumped to the ground without power.

''I knew I was getting old...!　To think that just one shot of the ultimate profundity can make you gasp...!
I've been flying around too much and I'm running out of energy. So this is our salvation. You can take care of the rest.

　Radey was horrified by the report.
　He didn't expect the most reliable force to suddenly drop out here.

"Don't get me wrong, Radey. Don't get me wrong, Radey, we're not the main players in this battle.
What?
''Don't forget, we're retired now. "Remember, we're retired, former heroes, former Four Heavenly Kings. Now you're the brave one, Raedie, of all people.

　The weight of the words was said by the brave man before him and the weight of the words fell on his shoulders.
　On both of Radey's shoulders.

　I felt as if I had been scolded for being spoiled.

　A grim determination comes to the dainty beauty's face.

'I'm sorry. I seem to have almost forgotten my duty.'
Good thing you remembered. Keep going. I don't want to see any of these bastards around.

　He draws his sword and shouts to the heavens with the sword's cutting edge.

''All hands on deck!　I will put an end to the demonic beast that our ancestors have weakened enough!

　As a representative of this era.........

''Now!　We are the guardians of this world!　It's our duty to break this crisis!　We will show the great ones that we have carried on that duty well!


　The courage of the brave spreads.

　Feeling the power welling up deep in their hearts, the adventurers rush towards the monsters with their legs faster than they can run.

　The demon beasts, which are unable to move quickly due to the damage, are unable to cope with the adventurers, and they end up taking them into their pockets one after the other and giving them all-out attacks in rapid succession.

''I envy you...!

　Seeing this, Glamberza said.

'It's not just Dariel,' said Glamberza. How dependable the next generation of the human race is! The next generation of the human race, how dependable they are, the next generation of the human race, how dazzling to me, who failed to even raise their own children. ........Hey, Zebiantes?
"Yes, that's right!

　Zebiantes tense as he is called by name as the same demon race side.

"I'm really worried. Will the future of our demon race be as bright as the human race?
'It's supposed to be brilliant!　Bashbursa is enough for incompetence!
"Then you go too. Then you go too. Show the next generation of demons that you are strong.
'Err, but...?　Like I said, with wind magic, the disadvantage of compatibility is...?
''A true mage would be the one who overrides the disadvantage of affinity with technology. .........it's no use, I'll give you the wisdom of an old man who has lived long enough.
Yes?

　In the meantime, Radey and his friends attacked together.
　It's a thorough offensive without a break, but even so, the fire demon beast Salamandra still won't fall.

　The adventurers are showering each one of them with their best desperate attacks, and even though they have a solid response, the fire dragon still won't fall.

''What life force...?

　Radey also constantly fired his 'Splitting Sky' into the thin armored abdomen, but no matter how many hits it hits, the outer skin just popped off and did not appear to be fatally injured.
　The two predecessors' special attacks slowed down their movements and allowed them to go on an all-out offensive, but they couldn't quite get to the final push.

''Quickly...!　I want to die quickly.　I can't keep my strength up........!
The Hexenbiest is getting ready to make her move!　All of us evacuate!

　Even the adventurers around them could be heard complaining like screams from some places.
　It's a good thing that you're not the only one who's tried to run, but it's so far away that your legs have become sluggish.

It's not good.........　At this rate, we'll be pushed back.......?

　Even Radey was about to lose his momentum, when.........

It's Yosakoi!

　Zebiantes ran through.
　He stood on the front line to confront the fire dragon on his own.

''Zebiantes!　What do you want now?
''Of course I've come to settle my colleague's scandal!　In the end, this me will prove the strength of the demon tribe with a brilliant decision!

　The wind magic is released boldly.
　Towards the giant flame monster.

''Hey!　I thought wind magic doesn't work on fire demon beasts!

　On the contrary, blowing in fresh air to increase the intensity of the fire could revitalize the Fire Fiend Beast.

''There's no need to worry!　I have a secret plan!

　As the person in question said, the wind magic that hit the target extinguished the flames caused by the flame monster beast.

''It's just as Granbaza-sama advised!　It's the only way we can fight the flames!
"What?　What does that mean?
What you just unleashed is a kind of wind magic, a spell that creates a vacuum!

　A vacuum is an empty space, where there is no air or anything else.
　There is no more oxygen needed to burn it, so any flames can only disappear.

''Vacuum expansion magic is the most difficult type of wind magic, so I want you to understand that it's only because I'm the Four Heavenly Kings that I can use it pompously!　That's what I'm talking about!
It's great, but it's kind of boring, don't you think?

　The flying tool that should be called a vacuum cutter unleashed by Zebiantes was not that large, and even if it hit, it would only shave off a couple of laying hairs.
　That would be about the size of a throwing knife.

''That's why I said it was high difficulty. Even though I am the Fourth Heavenly King, this scale is the best I can do.
''A leap of faith!

　Of course, the giant flame monster beast was unfazed by the small attack, which was little more than a poke, and steadily prepared a counterattack stance.

''Whaaaaaaah?　I'm not going to be able to make it in time!
''Run, run, run!　The breath is coming!

　The adventurers, who were struggling to attack, finally scattered away with an avalanche of attacks.
　Salamandra showed a gesture of taking a big breath.
　That's exactly the preliminary motion just before blowing the flame breath.

''This must be bad!　I have to run away too!
''Wait!''

　Radie grabbed Zeviantes by the scruff of the neck as he tried to run away like a gale.

'What are you doing?　If we stay here, we're both going to be roasted by a beautiful woman!
'Before that!　I've got something to try!　Throw the vacuum blade at the Flame Monster Beast again!
''Huh!''

　Even if he released a knife-like vacuum blade now, it was unlikely to have much of an effect on the Flame Demon Beast Salamandra.
　However, they didn't have the time to ask back and ask for a detailed explanation.
　In a few more seconds, a large area, including the point where the two of them were standing, would be a sea of fire.
　The only way to escape perfectly and survive was to stop the demonic beast's attack.
　Just make them stumble. Or even inflict a fatal wound.

''Alright we'll do it!　Eeeeee!

　The vacuum blade released from Zebiantes' hand. Due to the vacuum, there is no color or shape to be seen, but I can certainly sense a sign that it is there....

''Splitting Sky!''

　Radey released a slash of aura.
　It's a normal, ordinary, and much smaller than Dariel and Arantzill's 'Super Emperor's Rivendell', but it is a normal 'Rivendell'.
　It caught up with and met the vacuum blade that had been sent earlier.......

''Huh?　The vacuum blade and the slash of the aura........?

　They merged.

　The vacuum blade is forcibly expanded by the mass of aura, and its slash characteristics are also added to increase its sharpness.

''An aura slash that obtained the properties of a vacuum that extinguishes all flames...!　The name is 'Vacuum Splitting Sky'!
It is what it is!
Go!　Slash through the Flame Monster Beast's throat flute!
