I Have been Reincarnated As a Lazy, Arrogant Noble, but When I Destroyed The Scenario Through Effort, I Became The Most Powerful With Extraordinary Magical Power - 76

076 – Complete Conquest

Sirens are creatures from Greek mythology.

They have the upper body of a human woman and the lower body of a fish.

In Noblesse, if one is captivated by their singing, their magical power is hindered, and they lose consciousness, leading to death.

The singing mentioned here is like magic; it mixes a small amount of magical power into sound.

This becomes sound magic… and attacks us.

What’s more troublesome is that most dungeon bosses summon underlings, what you’d call regular monsters.

Each one of these is stronger than the average monster and takes time to defeat.

And Sirens, standing on a large rock surrounded by water, make attacking quite difficult.

But that’s the case for ordinary folks…

“Lalaa ♪ Lalalaa ♪”

The Siren, noticing our intrusion, began singing a beautiful song.

When I heard it in the original, I thought it was a lovely voice, but damn, does it really resonate in your head like this?!

“Ugh—!”

“Eek!”

Even Alan and Karta grimaced in pain.

At the same time, the door was firmly closed.

Escape magic and items exist, but we don’t have any of those.

Either we kill the Siren, or we die.

Ordinary people would have turned back at the door.

Taking on a boss with this number of people is downright crazy.

But we are proud students of the Noblesse Academy of Magic.

We’re confident, after all.

The Siren summoned its underlings.

Emerging from the water were grotesque, gooey humanoid monsters of various shapes.

“Devi!”

“Debbiebiebie!”

I chanted the Automatic Action mode and ordered the extermination of the monsters.

As my right arm transformed into a dark sword and my left into a dark shield, wings fluttered, and I took to the air.

I see, it seems Devi has evolved as well.

“Karta, the height here is no problem. We’ll buy time; you aim for the main body of the Siren!”

“Got it!”

“—Alan!”

“I know!”

Riding a broom, Karta soared high into the air. At the same time, I called out to Alan, but he understood without me saying anything.

Defeat the underlings, and if there’s a chance, attack the Siren.

The extermination… begins.

“Lalalaa ♪ Lalaa ♪”

In the original, there’s an HP gauge for the boss, but we can’t see it.

And this one also has wrath.

When it’s down to about 30%, its ferocity will likely increase.

“Gyogyo!”

“These guys are gross!”

I cleaved them in two with the magic sword Dual Sword. I noticed it during the time-lapse flash, but these guys, water creatures, have regenerating bodies.

But I can break their spell formations.

Looking at Alan, his sword of light was shining.

And to my surprise, the water creatures didn’t revive; they turned back into water and splashed onto the ground.

It’s infuriating, but it seems that the same effect as mine resides in that weapon.

Pure light, more similar to Shari’s elemental magic, I guess.

Well, it doesn’t matter for now. More importantly, the Siren.

“Debbie!”

Devi was excellent.

He must understand that Karta is the linchpin for the extermination.

While defeating the underlings, he’s guarding Karta.

Devi covers with a dark shield the water magic that one monster fired.

“Thank you!”

“Devi!”

And then Karta, unbelievably… conjured an immensely powerful magic from her hands and released it.

There’s no way but steady effort to increase the amount of magical power. Daily training, that’s what supports one’s future.

Karta probably hasn’t missed a single day. Since the day we teamed up, no, even before that.

Huh, the best alteration I made might have been not getting you expelled.

And Karta’s unbelievable magic cannon hit the Siren directly.

The damage must be substantial. A deafening roar reverberated, like a cannon.

When the song temporarily stopped, our magical power hindrance was lifted.

“Alan!”

“Yeah!”

Now we can give it our all.

Using that short time, we obliterated the underlings.

However, to my surprise, the Siren began singing again. It was a voice I had never heard before. As the water near its center gently lifted, it started to heal itself.

I’ve never seen anything like this.

“Karta, these underlings should also have magical power consumption. Keep attacking relentlessly!”

Infinity doesn’t exist.

We continued to attack in the same manner. However, the healing didn’t stop at all.

The conflicting spells of recovery and destruction are complex, making it difficult to chant while hindered.

In that case, a full-out attack from me, Alan, and Karta is necessary.

“Alan, simultaneously defeat the underlings and the three of us will instantly take down the Siren!”

“Simultaneously?! Can we even—”

“We can. We—we can do it.”

Underling monsters kept appearing one after another. There’s an abundance of water.

They aren’t immortal, but their numbers are limitless.

By the way, Devi in the sky seemed to nod as well. What a loyal guy.

Karta defeated the underlings with a controlled magic blast.

And when the time was right, I shouted.

“Now!”

In the next moment, we simultaneously defeated all the appearing regular monsters. At that moment, only the Siren remained.

“Unnatural Wall Annatural”

“Unnatural Wall Annatural”

At the same time, Alan and I chanted the same magic. Even though I desperately mastered it, I’m slightly annoyed by the imitation copy, but well, it’s fine.

But somehow, Wrath had activated without me realizing. The Siren aimed at flying Karta and launched water magic.

Its power was surprising too. The magical power seemed strong enough to penetrate defense magic.

All of it was aimed at Karta.

There’s distance between us to cut it down. In that case—

“Debbie!”

I understand. He’s doing it.

Devi chanted dark defense magic with all his might and protected Karta. Since the water magic was coming intermittently, he kept chanting magic with both hands raised.

Well, should I give him the title of the unsung hero?

“Well then, Siren.”

However, those few seconds were enough. With Karta’s magical cannon and Alan’s and my simultaneous attack, we brought down the Siren.

In the end, it let out a scream that was far from beautiful and sank into the water.

I don’t know how it works, but afterward, as the water dried up, a crystal-like magic core fell.

This is the soul of the Water Dungeon’s Siren.

Well, it was pretty strong, wasn’t it?

“Weiss-kun!”

Karta descended from her broom, and Devi, too.

“Debbiebi, Debbiebi”

“Yeah, you did well. Don’t rub your head against me.”

She’s a bit clingy, which is a bit of a hassle.

“Devi-kun, I’m a bit envious…”

“Huh? Karta, did you say something?”

“N-nothing, really!? It’s nothing!”

Turning her cheeks red, what’s that? Hasn’t the excitement of battle worn off?

“Thank you, everyone.”

Alan smiled innocently. Geez, he always manages to thank someone.

“It’s an exam, after all. Well, let’s head back.”

By the way, if you defeat the boss, the dungeon should disappear automatically.

In the original, if I remember—

A thunderous sound echoed, and everything was engulfed in white.

“The Water Dungeon has been conquered…”

Ah, come to think of it, was it like this?

▽

“…Huh? Did you clear the dungeon?”

Returning to the guild and handing the magic core to the examiner, they looked surprised for some reason.

Or rather, because we cleared it, some dungeons were interrupted as well.

Well, that doesn’t matter.

“Huh? Weren’t you the ones who told us to defeat the Siren?”

“Oh, well… not the Siren, but the little Cosiren in between. Um, it’s common knowledge among adventurers, though…”

“Cosiren…?”

Come to think of it, I remember seeing a similar small creature.

Looking at Alan and Karta, they shook their heads, indicating they didn’t remember.

…It was too weak for them to recall.

“No way, even with the Cosiren, we struggled so much, and now you’ve cleared the dungeon…”

“They’re the winning and runner-up combo!”

“Even that little girl!?”

Well, whatever.

“So, did we pass?”

“Huh? Oh, um, yes. Of course, you’ve passed. Um, cough. The ones who cleared the rank test this time are Weiss Fancent, Alan, and Karta Violet!”

Shouts of despair could be heard. If you don’t clear the test, your rank apparently drops. It must affect your missions.

But that doesn’t concern me.

And at the same time, it seemed that Lillith and Cynthia were found too.

They were being informed of their success.

Seeing me, they ran over.

“Weiss-sama!”

“Weiss, how did it go?”

“I passed. You guys too?”

“Yes!”

“And—uh, who are you?”

“W-w-w-well, you forgot about Nell, didn’t you!?”

Dangling cat ears… Ah, this one’s the girl who made it rain.

“Rain girl.”

“Rain girl!? My name’s Nell!”

“It doesn’t matter.”

“Nell-san, you were amazing. Thanks to you, the test was easy.”

“Dehehe, Cynthia was amazing too.”

…This Nell is a strange one.

And looking to the side, Alan was talking to Duke and Shari.

Karta was… with Cecil and Olin.

…There are quite a few of them.

I felt uncomfortable for some reason, so I tried to leave quickly, but Duke was waving his hands desperately.

If I don’t disappear before getting caught up—

“Hey! Weiss! Let’s have a celebration with everyone! It’s a rare occasion, you know!”

“Do some push-ups.”

“Oh, right! Weiss, are you coming too?”

It seems like no matter what I say, he’s not listening. Is his ears stuffed with muscles?

And Duke called out to Lillith and Cynthia.

Surely, they’ll decline, I thought, but their expressions were…

“Weiss-sama, it’s a rare chance, so let’s go!”

“It might be nice once in a while. Right, Weiss?”

“…Fine.”

“Enjoy yourselves,” Milch Sensei had also said.

I really don’t want to, but I guess I’ll follow my teacher’s advice.

“De… Devi…”

And Devi had a sad expression. Since the battle had ended, he must know what’s going to happen to him.

Come to think of it, I forgot to return him.

Well, speaking of which, this guy usually feeds on magical power, but can he eat regular food too?

…Oh well, can’t be helped. I guess I’ll take him along as an experiment.

“I’ll summon you with the bare minimum magical power. But don’t move too much.”

“De, Deviii!”

“Don’t rub your head against me…”
