Epic of Caterpillar

Meanwhile, within Genesis, in the Realm of Helheim, inside of Hel's Castle, a battle between the possessed Hel and Zehe was undergoing! Zehe's mighty magic clashed against all of the Necrotic Ruler's powers, causing explosions across the entire place.

Redgaria's sister was secured at long last, but Hel's body was now being possessed by the Necrotic Plane Ruler, who didn't wanted to let go of her at all.

"As long as I am here, we're not going to lose." Zehe's eyes glowed bright red.

Zehe's confidence and magic power quickly made the Necrotic Plane Ruler remember that detestable Fairy Demon Woman…

Kireina!

"Y-YOU…! Why do you remind me of her?! Of that damn… Kireina's smile?!" Roared the Ruler, his entire power overflowing through the castle.

The castle walls, floor, and ceiling started shapeshifting, made out of hard divine materials, they shaped and transformed into hundreds of floating spears, swords, and axes, loaded to the brim with powerful phantasmal souls, and then fired at everyone all at once!

"JUST DIE!!! RAAAAAHHHH!!!"

BOOM! BOOM! BOOM! BOOM! BOOOM! BOOOM! BOOOM!

Countless explosions spread everywhere, as Zehe utilized her mighty magic to create voids for every single projectile, sending them far away into a different plane altogether. Alone, she was resisting his blows!

"You think I can't keep up with your pitiful magic?! As long as you're not within your Plane, you're not as strong as you make yourself up to be!" Zehe said, several spheres of pure dark void emerged around her. "And I'll show you!"

"You'll show me what?! You're just TRASH!" The Necrotic Ruler roared, suddenly, two huge portals to the Necrotic Plane opened, as two huge titanic skeleton arms reached Zehe!

"[Abyssal Barriers]!"

Zehe quickly conjured barriers made out of her Abyssal Darkness Energy, concentrating all her magic power into defending…

However, these skeletal arms weren't normal ones at all!

Crack… crack!

"FOOL! These skeleton arms belong to my body itself!" Laughed the Necrotic Plane Ruler. "Your barriers cannot resist their might!"

CRAAAAAASSSH!!!

The barriers shattered into pieces, as Zehe quickly attempted to move everyone away using her magic before she were to tank the hit using her tough mech suit.

However!

"[Undead Knights Netherworld Blade Arts]: [Underworld-Slicing Slash]!"

SLASH! SLASH! SLASH! SLASH! SLASH! SLAAASH!

CLAAAASH!!!

A huge skeleton knight wearing black armor jumped in front of Zehe, protecting her from the huge skeletal arms and slicing through their tough exterior, leaving countless slashing wounds and cracks across their bodies, while reflecting their blows away!

"Father!" Zehe was shocked.

It was of course nobody else than Herbell! Zehe's adoptive father, who had decided to come along to protect both Redgaria and Zehe.

"Zehe, stay behind me! This old body of mine can at the very least protect those dear to me!" Herbell roared, his empty eyes blazing with phantasmal flames.

"YOU…! A mere Undead dares defy the Ruler of Death?!" The Necrotic Plane Ruler said furiously, his phantasmal death aura constantly surged from within Hel's body. "KNEEL BEFORE ME! [Undead's Absolute Authority]!!!"

FLAAAAASH!

"UNGH?!"

Herbell was suddenly hit with an invisible, deathly power that tried to take over his body and soul! It felt as if thousands of chains were trying to restrain him, to wrap around his soul and force him to submission.

"LEAVE HIM BE!" Zehe roared, gathering all her mighty magic. "[Divine Abyssal Darkness Magic]: [Absolute Black Nova]!"

FLUOOOOOSH!

A huge black hole emerged in front of Hel, as it started absorbing all of her power while the mighty energy of the Necrotic Ruler started distorting and weakening.

TRUUUUUUUMMM…!

"UUUAAARGGHHH….!"

The Necrotic Ruler roared in agony, as he controlled Hel's body, quickly trying to open more space between him and everyone else.

"RAAAAAH! I WON'T LET YOU CONTROL ME!!!"

Herbell suddenly erupted with a power within his very soul, as it spread like an endless wave of phantasmal blue flames. Bones and darkness were summoned around him as he fired hundreds of bone projectiles!

"[Undead Knights Netherworld Blade Arts]: [Phantasmal Bone Blade Rain]!"

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

The bone blades pierced across the Necrotic Ruler's many projectiles, while slowly beginning to break through his mighty shield.

"And I am also quite proficient on magic!" Herbell roared. "After all, I used to be the strongest magician of my kingdom! [Absolute Elemental Magic]: [Elemental Catastrophe]!"

A gigantic magic circle emerged on thin air, shining with rainbow light as the combination of fire, lightning, wind, earth, and water emerged, spiraling together, and reaching Hel, impacting her body and the one possessing her with a tremendous elemental explosion!

BOOOOOOOMMMM!!!

"D-Did we do it?" Wondered Yiksukesh, who was fighting the Undead that kept entering the castle with Jormungandr and Fenrir, while Loki was supporting everyone with her illusion and buffing magic.

"Hel!" Loki cried. "Are you there- Ah!"

However, as the smoke slowly dissipated, Hel's entire body was unscathed, her body covered by a big, black armor made of black bones, making her look huge, and completely different than usual.

With a single arm, she held a huge scythe imbued with Necrotic Energy that came directly from the Necrotic Plane Ruler himself, his strongest, Cosmic Relic.

"You've pushed me this far…" It spoke. "I commend your efforts, but this will never go your way, pitiful mortals. Not when I have already summoned my trump card, the [Cosmic Abyssal Necrotic Scythe of Eternal Death: Vernichtung]!"

FLUOOOOOOSH!

The powerful scythe exuded a tremendous aura of utter death, so strong that it caused several debuff and status effects on everybody facing him.

The auras of billions of souls surged from within the scythe, like an endless legion of groaning faces terrifying the hearts of those brave enough to look at it.

"T-That scythe…" Herbell muttered. "Ungh…! No…! I won't… kneel before you!"

"Step aside, father." Zehe said. "Our fight has yet to be over, Necrotic Plane Ruler."

"Let me step in as well." Redgaria sighed, walking in. "Annabelle, stay behind me. Sapphira, can you protect my sister?"

"I will!" Sapphire nodded.

"Hmph, a dark magic witch, an undead knight, and a failure of a necromancer…" Laughed the Necrotic Plane Ruler. "What could all three of you even accomplish against the might of my Cosmic Relic?!"
