Kireina had been given the simple task by Mammon to slay these invaders. To start off their alliance, she wanted to see what Kireina was truly capable of, sending her to war and fight off these thugs was a nice way for Kireina to get some nice and exotic snacks while also fending off this pest from the Gates of Hell.
The four Necrotic Death Lords were caught red-handed as they were absorbing the demonic energy through their grotesque Undead Formation and were also forming new demonic cores. Kireina didn't thought it a single second. She quickly infused countless skills, techniques and spells into her body and Divine Aura, expanding it widely as she teleported right next to the Undead Formation!
Rimuru and the rest of her family and allies also were teleported with her, as they surrounded the Necrotic Death Lords with their powerful auras!
Kireina quickly clasped her fingers as the entire place fell into her own Dimensional Domain, forming a pure dimension out of her Divine Aura of Supreme Divinity!
"W-What?!"
"We are trapped in a dimension!"
"W-What's going on?!"
"Wasn't this woman a Chaos-Attribute Supreme Goddess? Why is she flawlessly controlling space and time like this?!"
"W-Wait!"
The five Necrotic Death Lords were left shocked, trying to stop Kireina but Kireina ignored them and smiled and laughed back at them. She was enjoying this thoroughly! Their despairing skull faces was a delight to her sadistic mind.
The entire world around them went from blazing red to complete darkness, spiraling with crimson red light, purple, pink, and other chaotic colors rushing around, it was a sphere of chaos! But this thing was no longer just another space which was merely just walls closed together, this entire thing was an independent dimension by itself.
Kireina had made it use her various divinities, skills, and spells related to spacetime. She had recently gotten the Supreme Divinity of Distorting Voidspace and Fragmenting Spacetime which had appeared in her resent evolution as a Rank 2 Supreme Goddess. This amazing supreme divinity already allowed her to manipulate space to even supreme god-levels!
Combining this with her greater supreme divinity of chaos, creating a Chaotic Dimension was nothing hard to do, with a single thought, the entire thing was created!
"Oho? What is this little toy here? Mind if I just smash it?" asked Kireina.
"Nooo!!!"
"STOP!"
"W-Wait!"
The Necrotic Death Lords cried at Kireina to stop as they suddenly unleashed beams of phantasmal and dark powers towards her, but her family and friends quickly intercepted them with their blows, some of them were straight up sent back to the ones that conjured them with ease! They felt weaker than ever before for being inside of Hell, and now they were trapped here. Their total power wasn't even half of the original one!
CLASH! CLASH! CLASH!
"Uaggh…"
"Unngh?! I am so weak?!"
"This damn Plane is weakening us… we can't even crush these bugs!"
"Who are you calling bug, skelly-face?!" roared Rimuru, as she shaped her slime into a giant hammer and hit all five of the skeletons directly, sending them off the sky and hitting the chaotic dimension walls in the process with a thundering blow!
BOOOOMMM!!!
"Guuuaggh…!"
"S-Such power…!"
"S-She's also… agh… a Supreme Goddess!"
The skeletons who were supposedly as strong as supreme gods were reduced to way weaker than their original selves, and because they were in the delicate process of absorbing demonic energy, they couldn't properly defend nor move correctly, ending up receiving Rimuru's blow head first!
The group was thrown into the dimensional walls, clashing over it and then falling over the floor, hopelessly looking at Kireina, who smiled and showed her sharp teeth. She expanded her entire body and shapeshifted to their horror, turning into a massive mass of flesh and chaos.
"W-Wait!"
They tried to stop her but Rimuru and the rest of Kireina's family and allies got in the way, as Kireina expanded her abyssal and endless maws over the tasty Undead formation and devoured it completely!
CRUNCH!
Kireina began to bite it off, tasting all the delicious flesh and bones, all of it made out of Necrotic Materials, a new type of materials she had yet to find. The energy of Necrotic Energy was also new to her, filling her with the power of death.
"I see! So this is the energy you guys use?" wondered Kireina, as she swallowed the entire thing into her interdimensional stomach, dissolving the massive Undead helplessly…
A sudden wave of information and a bit of power rushed into Kireina's soul and body, she suddenly learned several things by merely devouring this thing, comprehending how the Necrotic Death Lords used Undead like formations and more, and how this could bring her some new possibilities to her own formation creation.
"This shall be a nice addition to the library of my knowledge." She thought with a smile, shapeshifting back to her fairy form and realizing that she learned the way to transform the demonic energy flowing across her body into a mild demonic energy and even into other energies… she was actually the ticket to the dream the Necrotic Death Lords had to conquer Hell, if they could get her help, they could acquire demonic cores incredible easily…
Of course, she wasn't helping anyone… she only smiled back at them with the smuggest smile she could muster, looking at them with her sharp teeth clearly covered in blood. She sensed how the cores forming inside the ribcages of the Necrotic Death Lords quickly broke into pieces, their entire process was ruined! Frustration, sorrow, anger, and utter horror all combined together inside of the Necrotic Death Lords' minds as they looked at Kireina and her allies with the most utter anger they could ever muster!
"Y-Youuuu…!"
"I-It is ruined! Our lifetime work…!"
"No…! Damn it! You damn ants!"
"H-How dare you do such a thing?!"
"Do you know that by doing this, you're declaring a war against our faction in Genesis?! Hel will hunt you and your people down! And even more… our Netherworld Plane and the Hegemonies won't rest either!!!"
However, their threats were of no importance to Kireina.
"Oh, really? You would be giving be a favor then!"
