The World's Hottest Demon King

Kühl was frightened.

Ash had asked me to visit the southernmost ruins, and just as I was about to leave, the stone monument suddenly melted.

Then, a large bird clad in fire emerged from the seal.

「No, no way......」

Kühl is an adventurer.

I've had many close calls in my life, and I've survived them all.

Through such experiences, Kühl has learned to keep her cool under any circumstances.

But no matter how much Kühl wanted to, she couldn't calm down in this situation.

「It can't be, a Demon King!?」

Kühl shouted in an alert voice.

If it appeared from the seal room, it must be the Demon King.

Kühl has defeated countless monster in her life, but as expected, she can't keep his composure when facing the Demon King.

The only person who could remain calm in this situation was Ash.

「Ho ho ho. It's been about 2000 years since I was sealed away by that nasty little girl, but it seems that people have been talking about how scary I am. Well, I've become famous.」

「A, answer the question!」

「You are one impatient human. Indeed, I'm the hottest being in the world, the 《Southern Emperor》」

「Just as what I thought, it's a Demon King......」

Once again confronted with the truth, Kühl shivered in fear.

Ash has already defeated one Demon King.

When I heard Ash's story, I thought, "Maybe the Demon King is weak" but that only sounds that way because Ash is too strong.

If you actually face the Demon King, you will understand.

Even if you confront the Demon King, you will be beaten up in an instant.

Even if it is.

As a disciple of a hero, I can't just run away without doing anything.

Even though there is an overwhelming difference in power, it doesn't mean that there is no way to win.

「You said you were going to eat my soul, does that mean you're going to kill me? If so, it's an unfulfilled dream!」

「Ho ho ho. You're a funny human, aren't you? Do you really think you can beat me?」

「I think so! because I know how to use all kinds of magic! I can use magic to put out your flames!」

The Demon King is covered in flames all over his body.

No doubt, he will use these flames to attack me.

In other words, once the flames are extinguished, the 《Southern Emperor》 is just a nagging bird.

「I'll strip you bare!」

Kühl instantly drew up the runes for 〈Aqua Cannon〉.

A bullet of water, the size of which could swallow the Demon King whole, is released at high speed.

Jyuwaaaaaaaaaaaa!!!!

Did it evaporate in an instant?

The moment the water bullet hit the Demon King, a large amount of steam was generated.

If she hadn't used the 〈Cool Zone〉 to cool my body, Kühl would have been steaming by now.

「Let's keep going!」

Kühl unleashes her 〈Aqua Cannon〉 one after another.

As long as I couldn't see the Demon King through the white steam, I wasn't going to let up my attack until my magic power ran out.

But

「Ho ho ho! No matter what era it is, human have always like to put up a useless struggle!」

The Demon King's unpleasant voice rang out, and Kühl shivered.

Her hand stops drawing the runes.

「This can't be...... why aren't you gone!?」

Even though she had fired tons of water bombs, the Demon King's flames had not diminished.

「Ho ho ho. Well, well, well, you're talking nonsense. Didn't I tell you that I am the hottest being in the world? Everything that exists in this world is doomed to be incinerate by my flames! There's no way I can be attacked by a human!」

「That can't be...」

Convinced that he was defeated, Kühl cried out in fear.

It is truly the strongest defense.

It seems that the 《Northern Emperor》 that Ash defeated also boasted the strongest defense, but the 《Southern Emperor》 can divert its flames into attacks.

Any attack from us would be ineffective, and that one would be able to kill Kühl with just a touch.

How am I supposed to win against an opponent like this!

「You already know, don't you? With the world's strongest defense and the world's strongest offense, I am the world's strongest!」

Kühl nodded disappointedly.

「I, lose......」

However, she raised her head and wipe away her tears.

「You're not the strongest person in the world. It's Ash-kun. I'll remind you in a minute that you're a frog in a well!」

Kühl cried in tears and teleported to escape.

◆

In the principal's office at lunchtime.

「......That's why I want you to defeat the Demon Lord, Ash-kun.」

I nodded my head as I listened to Kühl-san's recollections.

「That's fine, but is the notebook safe?」

My concern was not the Demon King, but the notebook.

According to Kühl-san, the stone monument has turned into a molten lava.

If the notebook had been burned, I would have lost a valuable clue to gaining magical power.

......Well, maybe there's nothing but bad things written about it.

「Sorry, Ash-kun. It didn't burn, but it got wet. I'm just drying it off.」

If it's in its original form, there's no problem.

When the notebook dries, I'll have Noir-san to decipher it.

「So, where is the Demon King now?」

If he's still in the ruins, I'm going to run and take him down now......

「The Demon King is heading straight for this academy.」

「It's heading here!?」

Ai-chan screamed.

Kühl-san spreads out a "map showing the whereabouts of the strong" on the desk.

Indeed, the red dot is moving in the direction of the academy.

At this pace, it looks like it'll reach Erstania by sunset.

A Demon King would have no trouble breaking the town's wards, and if left unchecked, Erstania would become a sea of fire.

「Do he believe my last words and are here to defeat Ash-kun? I didn't even tell him the place......」

Kühl-san looks at me strangely, but I know what the Demon King wants.

Just like the turtle last time, this time the bird is planning to take revenge on the 《Emperor of Ice》.

I'm sure the location can be determined by soul vibrations.

In other words, if Noir-san and I ambush the Demon King outside the town, we can defeat him without causing any unnecessary damage.

「Then I'll go defeat the Demon King.」

Kühl-san nodded.

「Be careful, Ash-kun. The Demon King of this time is different from the Demon King of the past, you know.」

「I hope so.」

You can grow mentally by confronting strong enemies, but until now, the Demon King died with one punch.

「You're very reliable.」

「This country's...... No, this world's survival depends on you, Ash-san. Please...... please defeat the demon king!」

「Please leave it to me.」

I said, and went back to the classroom.

Then I talked to Noir-san, who was chewing on a melon bread.

「I need a favor from Noir-san.」

「......Is it okay with a bite?」

Noir-san offered me a piece of melon bread that she was about to eat.

I'm hungry and I want to eat, but my request is not "give me a bite".

「You can eat the melon bread by yourself, Noir-san.」

「Is that so...... So what's the favor?」

「The turtle's friends showed up, if you know what I mean.　I'll tell you the details as we move along, but I need you to follow me.」

If you talk about a Demon King approaching in a classroom, it's bound to cause an uproar.

To avoid scaring everyone, it would be better to keep the Demon King a secret.

「I understand everything. I'll follow you.」

「Thank you Noir-san」

And so I and Noir-san went to intercept the Demon King.
