Epic of Caterpillar

While Flora, Aura, and the System Master fought against the Necrotic Plane Ruler, at the same time, Rimuru and the rest of Kireina's family, alongside Loki and her two children confronted a new foe!

Or well, the same foe that Flora and the others were fighting, the Necrotic Plane Ruler made himself present once more, as he stopped Loki from getting through his brainwashing of Hel.

And how? Well, by merely possessing her body completely!

After all, Hel was merely his new vessel, a compatible incarnation he wanted to use to conquer Genesis. She wasn't someone he even cared for at all.

In fact, the Necrotic Plane Ruler was an eldritch, outer being born from Death and the Void, and held no emotions other than greed and the desire to become stronger to dominate and conquer more.

He had never loved anybody, nor he had ever cared for anybody, nor he would ever do. His existence was filled with apathy, and he only saw other living beings as either tools, or enemies.

"HEL IS MY PROPERTY… Mother, or siblings, it doesn't MATTER! She's MINE!" His voice echoed furiously. The entire Realm of Helheim stared shaking.

Gigantic eyes opened everywhere across the Realm, tentacles made of Nether and Death Stone surged everywhere, as billions of Undead emerged endlessly from below the ground, attacking everyone together!

"Shit! This is just going to become endless at this point!" Nesiphae complained, crushing tens of tentacles at once with her Axe, which by channeling the power of her family, became a gigantic red-colored Axe imbued with Scarlet's powers of Space and Devour.

SLAAASH! SLAAASH! SLAAASH! CRAAAASH!

"We need to go beat Hel first! Her true body is not around here after all!" Said Rimuru, her entire body quickly becoming a sphere with sharp metallic spikes, rolling across everything and devastating all things in her path.

CRAASH! CRAASH! CRAASH! CRAAAASH!

"Then Loki and her siblings are going!" Brontes nodded, swinging her two enormous arms by channeling the might of her daughter and the Cyclops Gods of each Ore, the gigantic metallic fists were what Vudia called "El Dorado 3.0" and were capable of smashing anything in front of Brontes. To make things more fun, she already had a second pair of arms, which she used to wield her enormous Golden Club, smashing even more things with lightning and titanic strength.

BAAAM! BAAAM! BAAAM! BAAAAAAM!

"Alright then! We'll open the way for them to get there!" Said Zehe. "The space is too disrupted by the Aura of this bastard, so basic teleportation will be useless if he doesn't let us get through the spatial layers!" She conjured countless portals of darkness, summoning enormous tentacles, monstrous jaws, and giant claws from all sorts of eldritch beings which her magic could draw strength from.

SLAAASH! BOOOM! CRAAASH! CLAAASH!

"Woof! Then let's do it!" Wagyu nodded with his three heads.

"There's no other option!" Kekensha agreed. "Lord Fenrir, Jormungandr, Loki, Yiksukesh, come here with us!"

The two Wolves unleashed their Divine Auras as they ran across the destructive landscape. Dozens of gigantic phantoms surged one after another, trying to get in their way as they ran. The two wolves valiantly attacked them one after another, destroying them with their might while the ones they protected kept running.

Meanwhile, Rimuru and the rest followed them across the skies, attacking and protecting them from everything coming at them. It was as if the whole world they were stepping into wanted to kill them!

"There's no ESCAPE!" The Necrotic Ruler roared with fury.

TRUUUUUMMM…!

Suddenly, the ground right in front of Wagyu and Kekensha distorted, an enormous Titan made of Nether and Death Stone surged, holding billions of souls, a Primordial Death Titan!

"GRUOOOHHH!"

"T-This is looking mightily hard to beat!" Kekensha gritted his teeth.

"I guess it's time to bring out the heavy artillery!" Wagyu smiled, recalling one of Kireina's phrases that she brought from movies.

"I guess there's no other chance!" Kekensha agreed.

The two wolves glowed with bright auras of divinity, as several other wolves surged from their Divine Realms, as gigantic mechs!

The two also were covered in mechanic armors, as they flew into the skies and merged with the other colorful wolf-like mechs, forming a gigantic, humanoid mechanoid created from the fusion of many at the same time.

"Ugh, things are getting rather horrible right now…" Yuki sighed. "Wagyu, Kekensha, make this quick!" The busy mother of a few children, Yuki, emanated a cold aura of Frost Divinity.

"Alright! We're finally stepping into battle! LET'S FUCKING GO!!! GYAHAHAHA!" Kurimu, the red-horned blazing wolf god roared with laughter and flames across his body.

"We must remain calm and composed, everyone! Together as one, we'll be invincible!" A bulkier wolf said, Tsuchimizu, the calm and tankiest wolf of all Genesis, emanating an aura of both earth and water.

These, coupled with Wagyu and Kekensha were Kireina's strongest canine warriors, formers members of the Crimson Wolves with the exception of Yuki, who came from the Frost Mountain Walls, but easily was welcomed to the pack of powerful wolves.

After having undergone many reparations and improvements, their mechs finally combined together as one, more improved and divine version of it! Shining with red, black, golden, white, blue, and green colors, the powerful Rainbow Kaiser EX2: Code Wolf, has rolled into the scene!

"AWOOOOO!!!" The gigantic three-headed wolf-like metallic chest of the mech howled furiously, opening their jaws, and unleashing a triple beam of devastating proportions!

BOOOOOMMM!!! BOOOOOMMM!!! BOOOOOMMM!!!

"GRUOOOHHHHH…!"

The gigantic Netherworld Titan fell into the floor, crumbling apart in a mere instant as it couldn't even take more than two beams at once, let alone three!

BAAAAAMMM…!

Several tentacles surged everywhere, yet the mighty Rainbow Kaiser EX2: Code Wolf, slain them all with sharp wolf-like metallic claws and enormous laser swords!

"W-What is that gigantic metallic titan?!" Asked Fenrir in utter shock. "I-It is as if all those I've blessed had merged into complete and pure harmony with a powerful armor that combines their bodies and souls completely!"

"Impressive!" Jormungandr said. "Not even my gigantic body can properly withstand all of these attacks, yet it is fighting on equal terms with everything all at once?!"

"Heh… So this is the insane invention that Kireina created…" Loki smiled. "Even when she's no longer here, her presence, her inventions, and her will remains within her allies."

Rainbow Kaiser EX2: Code Wolf Enters The Battle!
