Epic of Caterpillar

As the walls were created and then shattered apart into pieces by the beams of nether a darkness, the Griever felt his tentacles being tore apart and sliced open into countless pieces. The weakening venom curse put into him actually managed to weaken his regeneration abilities, to the point that every limb he lost that was covered by this venom curse, would simply never grow back again. n/ô/vel/b//in dot c//om

"ROOOAAARR!"

"SHAAAAHH!"

The draconic forms of Fafnir and Emerald charged forwards. Fafnir used his enormous size and weight, and his massive jaws to tear through the tentacles and then burn them with his golden draconic flames. Emerald unleashed a storm of deadly winds with his breath, tearing through the monstrosity several holes.

BOOOM! BOOOM! BOOOM! BOOOM!

"Uuugghh…! GRAAAAGGHH!"

The aberration screamed, suddenly about to conjure the beams again, except that this time Alucard was prepared, quickly command his siblings as they acted as one.

"Big brothers Dereo and Caellaeno! Scarlet too, do it!"

"Yeah!"

"Alright~"

"Will this work?!"

The three siblings unleashed their Cosmic Powers at once, combining them into a giant downpour of devouring miasmic, blazing slime of red and purple color, wrapping around the magic circles.

"{Divine Cosmic Ability Synthesis}: {All-Devouring Infernal Blood Slime}!"

SPLAAASH!

The slime, which the Griever had been ignoring so far, gained incredible new properties, devouring the magic circles before they were conjured by tearing apart their magical structures.

The magic circles broke and the deadly beams that constantly threatened everyone were destroyed. At the same time, the children continued their onslaught.

Combining the power of Kireina\'s Pandemonium barriers around them, they unleashed explosive bombardments of spiritual demonic magic, combining the elements granted with their own.

BOOM! BOOM! BOOM! BOOM! BOOM!

"GRAAAAHHH! Y-YOU INSOLENT…! IT\'S… ALL YOUR FAULT!!!"

However, Alucard wasn\'t risking things, he kept his siblings a distance from the monster at all times. Because he knew that something at the level of the terrifying Recessed her mothers had fought before couldn\'t be just so easy to defeat.

"This is only the hidden boss of a dungeon mama made, but I am sure it has something deeper within it!" he thought. "It can\'t just die so easily, right- Ah!"

And then it came, the crimson eyes of the Griever opened widely as black and red energies surged from his aberrant, swirling, and mutant body, suddenly it started bulging constantly, forming giant bubbles of miasmic nether.

"GRUUOHHHHH!"

As it screamed, its mass began to expand rapidly, Alucard knew they had to retreat, and wasted no time telling everyone to pull back.

"Everyone, run!"

They quickly ran, evading the incoming blows from the monster\'s last four tentacles, as its body continued bulging like a balloon constantly.

"What\'s happening?!" asked Scarlet. "Can\'t I just eat it now with my powers?"

"If you try you\'ll end up with your belly exploding, don\'t do that!" Alucard said. "Even mama had her limits back then, don\'t risk it!"

"R-Right…!"

Scarlet was tremendously strong, but even Gluttony\'s Devour had its limits, and that was shown when Kireina literally died after eating more than she could digest in time.

TRUUUM!!!

A powerful shockwave was unleashed, and everyone quickly gathered together, as Aarae and Valentia combined their powers with the kids behind them, forming an enhanced, reinforced barrier.

Once the shockwave finally dissipated and ended, smoke covered the air, revealing the Griever\'s appearance… It had changed, it was now a ten-meter-tall black skeleton, everyone could now clearly see the crystal core inside of the ribcage, and its empty eye sockets suddenly grew crimson eyes.

"Hahhh…" it muttered. "Hahhh…"

Suddenly, flesh began slowly growing over the skeleton, Alucard\'s eyes widened in shock as he saw internal organs being formed too.

Just what in the world was this thing?!

"We can\'t let that thing regenerate fully…!" he said.

He had a feeling, an instinct perhaps, that if that thing fully completed its new transformation, things would only go awry.

Yet this was the perfect time for them to fight it and kill it!

It had become smaller, and above all, its core was now visible.

Kireina only watched in silence, squinting her eyes.

"If this is truly his fragment, what is this appearance?" she thought. "Did that tentacled thing… Ever had a human-like form before?"

Half of his face had already formed as his eyes looked at the children and then around, suddenly beginning to cry tears.

Tears of blood that became enormous as they hit the ground, creating a giant wave of miasmic, nether blood so acidic it could melt anything.

SPLAAASH!

And as it approached, everyone could feel it.

The grief of this being, their sadness, their sorrow…

And their endless hatred against all living beings!

"Why… Why do you have to exists?!" he continued weeping. "Hahhh… Why! Die… Please… DIE FOR MEEEEEE!!!"

Ding!

[The Floor 5 Hidden Boss has reached its Second Stage: [Endless Abyssal Grief Soul of Outer Death: Yer-bogarr (Star Eater Realm: Tier 8)]!]

[The realization of the futility of existence and life itself has left him in an endless state of grief. His tears of Miasmic Nether Blood will melt and absorb anything they touch.]

[Once he fully finishes his regeneration, he will reach his last Stage, achieving his Complete Power.]

"So that\'s how it is…" thought Kireina. "Now, let\'s see how you can handle this, children. Will you kill it before it transforms… Or you will let it become something you can no longer handle?"

Kireina seemed interested, as she saw all her children charge at once. The harpy children surrounded the monster as they unleashed storms of elemental attacks, all while Alucard, Uryphe, and Scarlet stopped the waves of Miasmic Nether Blood.

"If this is blood, then we should be able to control it!" said Alucard.

"I think we can…!" Uryphe stated. "But it\'s quite hard…!"

"Let\'s do our best!" said Scarlet. "I\'ll use it, my powerful Cosmic Dao!"

Scarlet\'s entire power surged endlessly, easily surpassing even Alucard in this very moment.

After all, she had her own personal Dao, a power that they had used to create a portal to Abyss.

But that it was also her own strength, which she learned to use.

"{Cosmic Dao of Blood Dimensions}!"

TRUUUM!

Space itself twisted and distorted as a domain-like formation was created, showing a dimension where only blood existed.

The deadly wave of Miasmic Nether Blood was instantly absorbed!

FLUOSH!

"Amazing…! T-This is… big sis\' powers?!"

Even Alucard, the gifted genius child, was left in awe.
