【The Rise of the Ugly Monster】 The Colossal Beast's Unique Organ and the Lightning Monster

* * *

(U-uwaa...)

As Dokugegon approached the giant sphere of light that had been glowing in the distance, he instinctively bristled his poison-drenched feathers.

This was because the true identity of that sphere was a colony of the glowing parasitic worms that had attacked him earlier.

Thousands, tens of thousands of writhing, string-like parasites had gathered... forming an inverted dome, like a massive growth on the stomach wall.

...Just looking at it was unpleasant... no, it was agonizing.

That was the kind of sight it was.

However.

(...There's "something" there.)

Enduring the distress, Dokugegon observed the dome and discovered that it was not merely a collection of parasites.

Because the parasites were constantly writhing, the surface of the "something" they were clinging to was occasionally revealed.

A dome-shaped "something," like a giant growth, protruding from the stomach wall.

Its true identity was unknown... but Dokugegon deduced that this "something" was an organ harboring immense energy.

This was because the parasites clinging to it were constantly glowing, unlike those nesting in other parts of the body.

That meant the parasites were undoubtedly continuing to suck energy... magic power, from that "something"!

The parasites weakened by Dokugegon's poison had likely tried to flee to this spot specifically to absorb magic power and recover.

(If that's the case... ugh, it's gross, but...!)

Having thought this far, Dokugegon steeled himself and began to circle the parasite dome.

Then, he created several oversized spheres of poisonous liquid around himself... and fired!

"""AAAAAANISAAAAAAH!!?"""

Due to their density... the poisonous liquid hit the parasites perfectly, without even needing to aim.

The parasites, drenched in poison, had their 【Poison Resistance】 overwhelmed by the barrage of liquid; they died one after another, plunking down into the lake of stomach acid.

"""KIIIIIIIIII-SS!!!"""

Of course, the parasites weren't just standing there taking the poison.

With a crackling sound, several yellow lightning balls flew toward Dokugegon!

"N'EEEEEEEEH!!"

Dokugegon continued to evade them all, swaying his body left and right, sometimes ascending sharply or diving deep!

"""AAAAAANISAAAAAAH!!!"""

Even dodging the occasional desperate suicide charge without a hint of danger, Dokugegon continued to shower the parasites in poisonous liquid.

When it came to aerial combat, Dokugegon had a significant advantage!

Dancing through the air as if swimming, he continued to fight for several minutes.

Finally, the parasites swarming the surface of the "something" became sparse, and the surface itself was exposed.

"N'eh...!"

It was a dark... eerie mystery organ, densely covered in fine hairs on its surface.

Dokugegon had no memory of being taught in school in his previous life that such an organ existed in the stomach.

However, what that organ actually was didn't matter to Dokugegon!

His goal was the subjugation of the Land Whale!

What he needed to do wasn't analysis... it was to attack this energy-rich organ, which even the parasites flocked to, with poison!

He would fight!

...Together with Emi!

...And then, he wanted to resolve this situation as quickly as possible and be released from this terrifying environment!

"N'eh!"

Dokugegon created an oversized sphere of poisonous liquid above his head.

The poisonous liquid spiraled, extending into a long, twisting shape, and transformed into a spear.

"N'EEEEEEEEH!!!"

But just as he was about to launch the high-speed rotating spear at the mystery organ... it happened!

<<<Whoa there! Hold it right there! That's enough of your mischief!>>>

A voice he had never heard before suddenly echoed inside Dokugegon's brain!

"N'eh!?"

Startled by the unknown phenomenon, Dokugegon lost his concentration; the spear above his head could not maintain its shape and reverted into countless small spheres of poisonous liquid.

Just before they fell into the lake of stomach acid, Dokugegon managed to keep them aloft, letting them float around him.

<<<I noticed my subordinates were decreasing, so I came to see what was up... and it's YOU!! You've got some nerve messing with my turf, huh, eh!?>>>

A vulgar voice, sounding like a thug trying to act tough, echoed in Dokugegon's brain once more.

And in the next instant!

BZZZT! BZZZT! BZZZT!!

Yellow lightning suddenly erupted in front of Dokugegon!

And... strangely, the lightning did not dissolve or vanish, but remained in the air, crackling as it began to form "something long and slender."

It was a creature with a snake-like body... countless limbs and wings... and the face of a lizard!

"N'eh..."

Looking at the eerie form with its countless limbs, Dokugegon was reminded of a centipede... and instinctively flinched.

<<<Huuuuh!? What the hell are you? Now that I look closer, you're that pet poison bird of that kid-shaped monster rampaging outside, aren't ya!?>>>

Glaring at Dokugegon, the lightning monster writhed its long, slender body and shouted in surprise!

For some reason, this thing seemed to be able to grasp the events happening in the outside world.

Then, the monster made a face of sudden realization and shouted again!

<<<I see... I see!! I've figured it out!! I've figured out that monster's aim!! I wondered why she'd suddenly shove you into her mouth, but... I get it now!! You "knew" about it, didn't ya!? The existence of this "Kodoku Organ"!!>>>

(Eh, no, I didn't know about it!? What the hell is a "Kodoku Organ"!)

The monster, who had shouted that, let its body flash with electricity... and clung to the dark mystery organ as if shielding it from Dokugegon.

Apparently, this mystery organ was the thing called the "Kodoku Organ."

<<<Come to think of it... you poison bird!! You're probably born of this "Plateau of Behemoths" too... which means you've got one too, don't ya!? This organ that promises infinite growth...!!>>>

(Eh, really!? I have something like that inside my body too!? That's gross!!)

<<<Therefore!! You understood it instinctively...!! No matter how powerful the Land Whale may be, this Kodoku Organ can be its fatal weakness!!>>>

(This is the first time I've ever heard of that!!)

<<<But, HOWEVER!! It's been thousands of years since I lost my original physical body!! I managed to 【Possess】 the Land Whale's bio-electricity, and though it's pathetic, I've fallen to the state of a semi-magical lifeform... which means I'm now one and the same with the Land Whale!! And that's EXACTLY why...!!!>>>

(Hie!?)

At that moment!

The monster in front of him let out an exceptionally loud crackle, erupting yellow lightning from its entire body to intimidate Dokugegon!

And then, it bellowed!

<<<I, the Thunder Yellow Emperor Dragon, Piriribichi Ragi Ubagire... WON'T LET YOU HAVE YOUR WAY!!!>>>
