The battle has begun.
　The adventurers behind them could not be helped.
　It's because they have completely used up their strength in the battle with the flame dragon just now.

　If it were true, there should have been several casualties when the flame dragon attacked us in the middle of the road.
　They wouldn't have had the time to come to the deepest part of the city.

''------''

　The Flame Demon General roared and swung his arms around.
　Each time it did so, flames were released and rained down from above me and Elfi's heads.
　We look out for each other and jump back from the spot to avoid the rain of flames.
　As for the ones I couldn't duck, I reduced the power with the "Magic Skill Usurpation (Spell Divaur)" and slashed down with the Jade Tathagata.

　Without even having to look at it, Elfi has surpassed all of the flames.
　Then let's do what we have to do as well.

　The Flame Demon General's race name is "Flame Giant (Muspelheim)".
　As the name implies, they are giants made up of flame magic.
　They are powerful demons, but their weaknesses are obvious.

It's a torrent of life, a whirlpool of swaying souls.
　Overflowing, gathering, pouring down.

　He grabs the magic stone and chants.

"Aqua cannon."

　I released a water attribute magic.
　It's easy to use and can increase its power depending on the amount of magic power it contains.
　The magic power of the magical stone and the effect of the 'Ring of Mighty Demons' made the power of the shells more than double that of normal.

"----

　The Flame Demon General, whose body was made of fire, reacted excessively to the water bombardment.
　It poured its own magic power into the ground and created a pillar of flame on the firing line of the water cannon.
　That firepower instantly vaporized the flowing water cannons, which are supposed to be advantageous in terms of their attributes.

''Aaaaaaaaah!''

　The Flame Demon General seemed to have identified me as a threat and rushed at me with a roar.

''Looks like you don't have much intelligence, .......''

　The earth demon general was intelligent enough to solve human language, but this guy seems to be different.
　He doesn't even pay attention to Elfie who has stepped back and is only targeting me.

"Loooooooooo!

　The attacks unleashed by the giants that are so big that they look up, have a terrifyingly wide range.
　I'm sure you'll be able to find a way to make it work.
　I'm sure you'll be able to find a way to make it work.

　Anyway, it's tricky.

"Acceleration."

　Increase your agility and focus solely on evasion.
　From the movement of his arms, the flow of magic power, and what he sees, he can predict the Flame Demon General's next move.
　I duck, duck, duck.

''Good!''

　With Elfie's voice, I swing my arms around and shoot another cannon at the fire demon general, who is chasing after me.
　I'm sure you'll be able to find the right one for you.

''----''

　The defenseless flame demon general is consumed by the explosion.
　He braced himself for Bertoga's intervention, but nothing happened.
　Didn't that guy come here?
　Or .............

"Roooooooooooo!

　The Flame Demon General rushed out through the explosive smoke.
　The flames that make up his body were wavering from the damage he received.

''...... I guess we still couldn't defeat it.

　A normal flame giant would have been able to slaughter enough even now.

　The Flame Demon General's body wavered.
　The color of the flames that make up his body changes from red to blue and eventually to black.

　I take a distance and drop down to Elfie.

''A ...... black flame giant, huh? It's a rare species. I've never seen one before either.
How much magic do you have?
As long as it's only a matter of time, it's just as powerful as that demon. It's going to be tough to beat him in his current state.

　I turn my attention to the adventurers behind me.
　They're still there, but they don't seem to be coming to your aid.

It's a matter of course. Elfi, please.
............

　Elfi reaches for the 'bracelet of disguise'.
　It's a magic item that hides your species, which I made him put on before he entered the spa city.
　It's an effect that changes the nature of the magic to human, so the power of magic is reduced while it's on.

　The strong magic power blows out of Elfi, who took off her bracelet.
　It is not a human thing.
　It's the magic power unique to the demon race that makes your skin tingle.

...... If I could, I would have avoided it.

　Elfie says, frowning and going all out.

　...... Oh.
　In some cases, you'll have to kill all the adventurers, you know.

◆

'Shit ......, what can I do about it? ......'

　The majority of the gathered adventurers had become desperate for the Flame Demon General who had appeared.
　The majority of the adventurers' magic power had been exhausted in the battle against the Flame Dragon.
　Even if there were barely any of them left, it wasn't enough to withstand the battle against the Flame Demon General.

　Most importantly, the majority of the A-rank adventurers who were standing in front of the Flame Demon General's first strike had left the majority of the A-rank adventurers unable to move.
　The few remaining potions were given to them as a priority, but their formation was still rattled.

　In such a situation, an event occurred in front of their eyes that further reduced them to despair.

...... Fake, right?　That ...... is a demon.

　She was seen as a ray of hope for winning against the Flame Demon General, the "Explosive Magic Eye User".
　It's a good thing that you can't get rid of the bracelet that looks like a magic item and the magic power that flowed out of her was the magic power of the demon race.

"No such ...... demon race,
That guy's been cheating on us?
Then that guy next to me, Iori, is actually a demon: ......

　Demons are the enemy.
　They are an opponent of war, a hateful race that has killed many humans.
　The fact that it had been right next to them until now made the adventurers pale.

''But ...... those guys are fighting the flame demon general?　Why is that ......?
Maybe he's on our side.
''No, if we defeat the Flame Demon General, we'll be the next ones to be killed ......!

　Fear mingled in their eyes as they looked at the two men.
　The atmosphere was beginning to look grim.

''Chill out!　Those two men have saved our lives so far!
Maybe they had a purpose in mind!

　Misha's words were denied by the adventurers, and they fell into doubt.

　Misha himself was surprised by Elfi's true identity.
　It had never occurred to her that she was a demon race.

''Why don't we attack those two with the Flame Demon Generals while we're at it!　Now that we're both distracted, we might be able to kill either of them!

　A man wearing a full-face helmet finally made such a suggestion.
　Although no one immediately agreed with the quintessential, the emotional impact on the two men was rapidly deteriorating.

　Eventually, one conclusion was reached.

''Leave the two of them and flee this place.''

　It would be tough to get out of the labyrinth alive when you're physically drained.
　But it's better than being here.
　That's when the adventurers made that decision and were about to flee.

''----!''

　The Flame Demon General abruptly changed his target.
　A jet-black shell was fired at the backs of the adventurers who were trying to escape.
　That's when the adventurers peeled their eyes away from the dazzling amount of heat.

"--"Heavy pressure crush"

　The falling gravity knocked the shells down to the ground.
　It's not just a matter of time before you'll be able to get your hands on it.
　I'm sure you'll be able to find a great deal more to say about it.

That guy ...... now!
''You saved us ......?''

　The adventurers stop at the situation of being saved by the demon tribe.　
　If you intend to kill yourself, you wouldn't have to cover up for yourself right now.
　You'll be able to find out what you're looking for.

"You're a demon tribe, aren't you ......?　'Why?'

　There was no one to answer the murmur that overflowed from one of the adventurers.

◆

　...... outnumbered.

　Enough time has passed since the battle with the Flame Demon General began.
　If things go in order, it's about time that Elfi is already firing his all-out magic eye.
　However, because he protected the adventurer who tried to escape, he has consumed the magic power for the magic eye.

　Elfi-me .......

''Roooooooooo!''

　Seeing the attack of the Demon Eye, he must have realized that Elfi was in danger.
　The Flame Demon General is gradually becoming more and more focused on Elfi.
　I could see fatigue gradually building up on Elfi's face as he defended against it.

''--Huh.''

　I approach the Flame Demon General and divert my aim from Elfi to me.
　I duck a powerful arm strike that falls from above and counter, but it's played by the black flame.
　It's pretty hard.

　Even so, he doesn't let up on his attacks and repeatedly slashes at me with his jade taiji.
　In the midst of this, he chanted and fired a "running water cannon" into the face of the flame demon general.

　The blow with the full force and power of the flame demon general was greatly upset.
　It's a weak point, the water is shot into the face, which is a vital point, and the extent to which it is turned up .......

　He looked at the hardness of it and made his next move.
　He throws two magic stones at the staggering Flame Demon General.
　I'm not going to be the only one who has the ability to do that.

"Le ...... oooh!

　The Flame Demon General that leapt out of the explosive smoke is still alive and well.
　But it's not unscathed.

　Unlike the rock cave dragons (earth dragons), the body of a flame giant is bare magic power.
　No matter how hard they are, they can still take some damage from an attack by magic power.

　The damaged Flame Demon General's attack will focus on me again.
　Just because the flame demon general approached, a considerable amount of heat burned my skin.
　Although I'm defending myself with my magic power, I can feel my strength being lost every second.
　Until Elfi releases his magic eye, I'll just have to force myself to do it.

""Acceleration (Accel)"

　Magic that increases agility.
　I increased my movement one step, but the Flame Demon General's huge body was chasing me.
　So I raised the speed one more step.

"Double acceleration."

　I felt my whole body creak.
　The more agility, the more strain on my body.
　My bones and muscles screamed at the impossible exercise.

''Ooohhhh!''

　The movement through the forcefulness of the movement tossed the Flame Demon General.
　I'm not going to be able to say that I'm not going to be able to do anything about it.
　In an attempt to catch me, the Fire Fiend General is desperate to unleash his magic in a desperate attempt to catch me.

　I duck, slash, duck, slash, slash, slash.

"Huh? ......

　Even though he was vomiting blood, he continued to attack the Flame Demon General.
　He maintained a speed that he could not seem to catch, so that the Flame Demon General would not become numb and use large-scale magic.
　While making that calculation, he remained vigilant to see if the adventurer would betray him or if Beltranga would appear.
　My brain is about to burn out.

'But--'

　And that's over.
　Elfie, with his full magical power, sends us a signal.

"Shoot straight!
----!

　In the next moment, my vision was dyed with red lotus.
　The demon eye is eaten and the body of the flame demon general explodes.
　That blast also reaches me as I jumped backwards.

"--"Demon Sealing (Il Ataraxia).

　A shield that has been adjusted so that it can be used with the magic power in hand.
　It consumes all of the magic stones that can be used at the same time and most of the magic power in your body, and then it is activated.
　The Demon Sealer prevented the incoming blast.

　The Flame Demon General, who had lost most of his body, fell to the ground.
　The flames are extinguished, exposing the black body underneath.

''------''

　An ear-splitting decimation.
　Leaving behind a disgusting cry that seemed to call out something, the Flame Demon General died.

◆

　The demon general was defeated.
　But Beltranspire didn't come out.
　What the hell is going on?
　What the hell is he doing?

　I looked around nervously, but he was nowhere to be seen.
　Elfie and the other adventurers who are gathered around the entrance to the room are the only ones who are here.
　Isn't Beltooga gone?

　That's the moment I loosen up.

''Geeeeeeeeeeeeeeeeeeeeeee!

　The river of magma flowing at the back of the room.
　A flame dragon jumped out from within it, letting out a high-pitched cry.

''You're still here ......!''

　Due to the double acceleration, his strength was exhausted.
　You want to leave some extra energy, but it's hard to deal with even a flame dragon.

　I'm not going to be able to get it right.
　It can't be helped.
　It was time to take a stand to intercept it.

''...... release (purge).''

　With a thump, I heard something fall to the ground.
　I turned around and saw a man I didn't know standing there.
　It wasn't Bertoga.

　But the armor on the ground belonged to that full body armor that had tangled with us so many times.

　The man takes off his helmet, basket hand, armor, and all of his equipment and holds up a large sword.

' ...... more like thirty seconds.

　The moment he muttered that, the man's magic was blown out of him.

'Na......'

　The man steps off the scaffolding and takes a huge leap.
　Ahead of him is a flaming dragon that is about to release a breath.
　A split second before the flame dragon tries to change its aim at the approaching man.

''Raaah!''

　The man's large sword cut off both sides of the flame dragon.
　The flaming dragon, which was cut in half, falls to the ground while scattering fresh blood.
　Delayed, the man landed on the ground.

　A hush fell over the room.
　There was no more sign of the demon.

◆

　With a ragged breath, the man turns his gaze towards us.
　The adventurers are coming towards us, too.

'............'

　With that, I was on the verge of war.
　Apparently, that man had some extra strength left.
　There might be some other adventurers left who can do that thing.

"Elfi.
............

　The adventurers have found out that Elfie is a demon race.
　I can't trust them.
　And if this gets out, things could get ugly.
　If you want to take care of him, do it here and now.

　In the midst of all this caution, one of the adventurers spoke up.

You've been very helpful. Thank you.

　is ......?

　The other adventurers continue to speak as they are taken aback.

''You two are amazing!　I can't believe you defeated the flame demon general!
Did you say Iori?　That was a crazy move on your part!
"Firecrackers."　That was so cool!　I'm in love with you!

　It's a slap in the face, a thank you.
　Everyone comes at us in a friendly manner.
　There's no hostility.

'What ......'

　They must have figured out that Elfi is a demon.
　And wouldn't he just attack us?　
　Isn't he going to throw away the favor he owes you and come after you, hoping you'll be paid for capturing a demon?

I guess we're not gonna have to get our hands dirty.
'No, no. ......'

　While I was puzzled, the man from earlier walked over.
　That's right.
　This guy has gotten into a lot of trouble with us in the past.
　He's going to show his true colors, and he's going to attack us.

"I'm sorry about the past,

　That's what I thought, but the man bowed his head towards us.

I'm sorry for the delay in helping you. I was knocked unconscious by that giant's blow.
Hmm. ...... You're a demonologist.

　Elfie said, looking at the man.
　Demon Disease.
　It is a disease that rarely occurs in those who possess a large amount of magical power.
　It is said that they always release their magical power from their bodies.

I'm sure you'll be able to find it. Yeah, it's hard to put on the armor that keeps the magic power down. If I take it off, I can only fight for a few dozen seconds.

　With that, the man puts on his armor again.

'............'

　No one here has any animosity towards us.
　The adventurers are flocking to Elfie, even though they know he's a demon race.
　'Get out of the way,' Elfie fusses, though.

'What is it with those guys at all ......?'

　Elfi returned.

　The man put his armor back on and then apologized again, "I'm sorry," he said.

　The man's name is said to be Zorkin.
　He's an A-ranked adventurer.

I just couldn't let the kid fight.

　He began to tell me that.
　He had two children, apparently.
　The child had become an adventurer because he admired Zorkin.

What happened to ......?
...... is dead. They're both dead.

　With a regretful look on his face, the man said.


'So inevitably, when I see a guy close to their age playing adventurer, I want to stop him. But ...... I was wrong. I'm sorry.

　Zorkin bowed deeply.
　That's when he was about to open his mouth.


''--then I'll take you to that kid in a heartbeat.


　Zugan, there was a sound.
　Zorkin, who was standing right in front of him, was blown away.
　He then rammed into Elfi, who was standing ahead of him.

''...... ku!''

　As soon as possible, Elfi caught Zorkin.

"You've caught me,

　The flaming golden rod was swung down on Elfi, who stopped moving.
　Zorkin and Elfie, the two of them make a disgusting sound and crash into the wall.

"O ...... you, what are you doing?

　The one who attacked them was an adventurer wearing a full-face helmet.
　The adventurers around him let out a stunned cry.

　The man takes off his helmet.
　At that moment, there was a cracking sound and the man's body transformed.

''Humanization Armor. It was just a very rare magic power granting item. No one noticed it.''

　A man over three meters tall.
　His sallow skin, rocky muscles, and horns sprouting on his head.

'Yo, long time no see--Amaztu.

　At last.

　You're the traitor who tried to poison me once.

　Bertoga was there.
