Epic of Caterpillar

When Hel managed to somehow get rid of Kireina in an unexpected way, she thought that things would become much easier without the All-Devouring Supreme Goddess of Chaos and Demise, though, she was terribly wrong. Her family had inherited her powers as, in the very last minute, she divided her entire Divine Realm into four Fragments, giving them to Rimuru, Zehe, Nesiphae, and Brontes.

Within them, a great fragment of Kireina's true power was carried, and with all the things and powers she left behind, even including Divinities, Daos, and even the ever-growing and developing Realm Core of the Realm of Vida, which was completely assimilated into her Divine Realm by now, their power was constantly surging!

Rimuru, Zehe, Brontes, and Nesiphae channeled all of their own powers, alongside the powers that Kireina left for them, and the strength of their family members. Their bodies transformed, changing in nature and appearance, as they resembled enormous, mechanical knightess overflowing with divine power.

Colorful, and with their strongest divinities and the divinities and Daos of everyone else fused with their souls, their power almightily surpassed all expectations! And even Loki and Yiksukesh received a similar treatment, channeling the power of their close friends and families, even if they didn't had any of Kireina's Supreme Divine Realm Fragments themselves.

Hel was naturally shocked, incapable of comprehending where all of this power was coming from! Kireina's legacy wasn't going anywhere, and she could sense behind them, her very strength and will still remaining within! It was as if their combined auras formed a beautiful rainbow fairy demoness, smiling defiantly against her almighty divine strength!

"Kireina, Kireina, Kireina! I am tired of that bitch!!!" Hel roared with divine fury, the entire skies of the Realm of Helheim trembled, and so did the ground below, as countless gigantic arms, bigger than mountains themselves started to surge from the ground, attempting to crush her foes where they were standing!

"I'll kill you all! I'll CRUSH you all! When she's finally back, there will not be a single speck of dust left behind from YOU!!!" Hel roared, attacking furiously.

CLASH! CLASH! CLASH! CLASH! CLAAAASH!

RUMBLE! RUMBLE! RUMBLE!

The entire Realm of Helheim became her body, she was absolutely unstoppable, a being that was already surpassing even the might of Supremes!

However, they did not falter either, her opponents carried Kireina's might, her charisma, and her relentless will!

"Ailine! Wall! Gubo! Slime Family!" Rimuru roared, channeling the power of all Slimes within her Divine Realm. Her daughter, and all other named Slimes responded to her call, and even the Goddess of Slimes herself, Blooia!

"Mama, take all my power! [Primordial Divine Color Magic]!" Ailine cried, her shining rainbow eyes imbuing themselves into her beloved mama.

"Let's do this, Lady Rimuru!" Wall cried. "[Divine Primordial Slime Wall's Protection]!"

"We ain't giving up guubooo!" Gubo roared. "[Myriad Divine Primordial Slime Legion]!"

"LET'S DO THIS!!!" The Slime Family roared together. "[Multi-Elemental Slime Divine Primordial Aura]!"

"Rimuru, you've already surpassed me long ago! I am proud of you, my dear daughter!" Said Blooia, smiling happily, her divinities becoming Rimuru's! "[Primordial Slime Divinity: Eternal Slime Sea]!"

All their powers converged together into Rimuru's body, as her rainbow slime body shone brightly, materializing into a metallic, mechanical maiden of great beauty. It was as if her slime was also like divine-level liquid metal.

"RAAAHHHH!!! [Supreme Divine Slime Punch]!"

Rimuru unleashed her classic technique, now boosted by a millionfold! An enormous, titanic fist of rainbow metallic slime surged from within her very body, ascending into the heavens of the Helheim Realm, and clashing against Hel's manifestation!

BAAAAAAAAAAMMMMMMM…!

"UUUAAGGGHHH…!"

Hel screamed in agony as her manifestation was punched in the face mightily! Completely out of her wildest expectations! The punch wasn't just a punch though, as it carried the divinity might of all slimes together, and several other of their children too.

FLASH! FLASH! FLASH! FLASH! FLASH! FLASH!

Countless bright rays of colors emerged from within the fist, Ailine's magic! They absorbed the colors of the environment and distorted space itself, piercing through Hel's gigantic manifestation.

Thousands of colorful explosions started spreading across the skies, tearing down Hel's manifestation piece by piece!

"UNNGHH…! M-My manifestation?! What sort of strange magic is this?!" Hel had never seen Color Magic before, so she was naturally completely shocked by its prowess.

"And that's not all!" Rimuru's voice echoed, as the gigantic fist suddenly shapeshifted, lifting her up into the skies.

Her entire body turned into a giant liquid metal sphere as countless spikes surged from her entire body, enhanced by Wall's incredible durability, each piercing blow constantly damaged the manifestation more and more, and it even, somehow, hurt Hel's soul as well.

CLASH! CLASH! CLASH! CLASH! CLASH! CRAAASH!

"T-This is unconceivable!" Hel muttered. "BEGONE!"

Her Manifestation quickly materialized hundreds of gigantic, Abyssal Necrotic Skeletal Claws, attacking Rimuru from all sides!

BOOM! BOOM! BOOM! BOOM! BOOM!

"Not yet! I will avenge Masta!!!" Rimuru roared, her entire body quickly transforming into a gigantic sea of pure rainbow slime, divinely overflowing with hundreds of divinities and the powers of her many Daos!

SPLAAAAAAASSSSHHH!!!

The seas ascended into the skies, covering the black clouds, and consuming them like a slime would consume their prey. Hel's manifestation was instantly destroyed!

Crack… crack!

And a few cracks appeared within her soul…

"Unnngh…! Y-YOUUUU!!!"

Hel imbued more and more of her powers, as her Manifestation was summoned once more, surrounding Rimuru as the manifestation divided itself into countless of skeleton-like specters.

"DIEEE!!!"

Several scythe attacks reached Rimuru all at once, while she was still in her primordial slime sea form!

"Not so fast, you goth bitch!" The voice of Nesiphae echoed from within the skies, as she descended from above, having already flied there.

Her entire body was now covered on a powerful divine mechanical armor, a construct made out of the materialization of Daos, Divinities, and the temporary fusion of her many Divine Relics!

The power of Nirah and Scarlet were channeled into her body, as her arms suddenly changed color, turning to a metallic red, and transforming into long, monstrous centipedes, with sharp, axe-like ends, as she swung them around, slashing and tearing apart Hel's manifestations!

CLAAASH! CLAAASH! CLAAAASH! CLAAAAASH!

"AAARRGGH…!"

Crack… crack!

And Hel's soul kept gaining more cracks, weakening her bit by bit.
