Epic of Caterpillar

"Phew, we are finally back, everyone, guuuu!" said Rimuru.

"It seems that they're handling thing well… most of the Demons are already all wiped out!" said Brontes.

"Indeed, they did a splendid job… although three eyesores here might need to be promptly taken care of," said Nesiphae.

"It also seems like Honey's True Body Clone from here has finished her business, and four other Gods had died by her hands, these three are the last remnants of Hephaestus family!" laughed Zehe.

Rimuru, Brontes, Nesiphae, and Zehe flew back towards the Dark Moon Empire, a Kireina had told them that she wanted them to assist their children, family, and friends against the upcoming threats, finally reaching the Empire when the three Demigods, children of Hephaestus and Kabeiro had made their comeback!

"Mommy is back, guu!" said Ailine.

"Mommy!!!" cried Vudia.

"You took some time… Hm? Where is a mother (Kireina)?" asked Ryo.

"Mother, where is mommy (Kireina)?" asked Amiphossia.

"Kireina's True Body Clone that came with us is doing something very important as of now, so for now, we have to work together to defeat these Demigods while she's busy!" said Nesiphae.

"Well, although the Kireina from here is already coming here!" said Brontes, pointing at the sky, as a Chaotic Domain where Kireina with the rest of her wives fought against the Four Graces began to break apart!

Crash!

Kireina's True Body Clone that was with the rest of her wives fighting against the Four Graces freed herself from her domain after she ate all four of them, fused as one with all of her wives in a titanic demonic mech, she flew out at last towards her family!

"Mommy is back!" cried the children, as all the rest of their mothers came back as one gigantic entity.

"I am back indeed! Well, we are all back! Good work everyone, you massacred these invaders quite well… I am sorry for taking so long, killing four Gods at the same time is really quite tiring," said Kireina.

Aside from that, all of Kireina's children, their allies, servants, monsters, and friends, were all gathered around the Demigods too.

Cabeiri, Cabeirides, and Thalia, the three Demigods, children of Hephaestus and Kabeiro, and the last surviving forces of the Hephaestus family, as they were being surrounded.

Some of them began to regret having come back here.

Especially the moment they felt like the lives of their parents and sisters disappeared, only for their presence to remain within Kireina…

Despair quickly surged inside of their minds, as they were now on the horns of a dilemma…

Their parents died.

Their sisters, stronger than them, died too.

What could they do now to survive?

They had to fight, there was no other thing they could do now!

The three Demigods began to burst all of their Divine Energy, gnashing their teeth in anger and releasing all of their power into their Divinities!

Flash!

"These lowly mortals… they killed… all our family!!!"

"Kill them, we have to avenge our family!"

"Even if we can't win, let's take as many as we can with us!!!"

The power coming from the three Demigods began to surge, as they started to use the fragments of something to boost their prowess!

"Don't tell me… another fragment? Now what? Oceanus?" asked Kireina.

"Fragments of Oceanus!" roared the three Demigods, converging into a gigantic being made of oceanic divine water and aura, covered in countless isles and even volcanoes, reaching over one hundred meters!

FLASH!

"Oh, I was actually right…" sighed Kireina, as her wives fused with her laughed a bit.

"Let's go, everyone!!!" roared Ryo, commanding his siblings as the enormous force of Kireina's children converged into a gigantic army, charging their most powerful attacks and spells, and firing them at the gigantic 'combination' of Gods.

"Divine Battle Technique: Myriad Self: Axe Form, Spear Form, Blade Form!" said Ryo.

Ryo released his incredible Battle Spirit Divine Aura, as countless clones of himself made through this aura converged into one, shaping themselves as gigantic fists or weapons, clashing against the titan and leaving deep wounds into the combined souls of the Gods, making them quickly falter!

"Everyone, go!" said Aarae.

"True Monster Form! Shadow Breath!" roared Valentia.

An army of Sharks commanded by Aarae torn down the giant's left leg while exploding and leaving even more damage and Valentia shapeshifted into her monstrous form, becoming a monstrous creature, and tearing down the massive army of Divine Beasts coming from the giant's body, alongside releasing giant breaths of shadow and powerful tremors.

"Everyone, fuse! Transcendental Phantasmal Spell: Spectral World of Death!" said Amiphossia.

"Heavenly Shining Blades! Golden Sun!" roared Evan.

The titan began to release countless blades of water over the enemy, however, Amiphossia emerged, flying up in the skies and converging thousands of ghosts, specters, and other undead, combining them into an enormous sphere of phantoms, wailing and monstrously charged with power, firing it towards the titan of water and dealing enormous damage on its torso!

To her side, Evan used his newly acquired techniques after becoming a Legendary Hero, alongside Durandal and Sol's Sun Blade, he released enormous glowing slashes of light and fire, alongside gigantic spheres of light, Golden Sun, towards the giant, adding into the damage that was stacking into the fused soul of the Demigods.

The Demigods roared, releasing more blades and spears of water, torrents of concentrated water pressure, and other things, but most of them were either evaded or completely reflected by Kireina's family and allies!

"El Dorado, Super Concentrated Electric Release!" said Vudia, commanding her gigantic mech golem, El Dorado, and infusion all of her power into it, as it released a gigantic torrent of lightning towards the giant of water, electrifying it almost entirely!

"Let's see… Magic Domain release, let's make… twenty! Compress and fuse…! Ready!"

At her side, Ailine also did her work diligently, as she flew out of El Dorado, generating several Magic Domains through her monstrous Magical Aura, converging the Domains as the catalyst, and then conjuring a Spell through them!

Indeed, this way, Ailine was able to generate incredibly powerful spells in little but no time!

No one else, not even Kireina, has ever figured such a way of fighting, y simply using Domains as a catalyst to conjure enormous spells!

Ailine generated a gigantic rainbow door within the skies, which released a judgment of materialized rainbow energy into countless weapons, exploding all over the giant of water as the three demigods within tried to fend the overwhelming spell off!

"Let's do this for justiceeee!"

The Harpy Siblings also joined in, combined as one and then by commanding the gigantic mech, they marched through the battlefield, converging their gigantic Auras into enormous weapons which they used to attack from long distance, or even by blasting several cannons with it as well, anything went for them!

"Divine Eclipsing Aura! Eclipsing Sun!"

Adelle used her gigantic mech to enhance her magic even further, and by employing her Divinity and Divine Aura alongside the Divine Energy she had saved, she created an enormous aura of light and darkness, combining it and then firing it towards the oceanic giant into a sphere of dark and light!

"Corrosive Venomous Soul Fighting Style! Snake Whips!"

At Adelle's side, Nirah used her own mech and combined it with the abilities she had been discovering and awakening within her potential as the reincarnation of Megusan, a Demon Demigod.

Using Megusan's technique of covering her own body with her corrosive soul, she extended her mech into gigantic metallic whips, beginning to wipe the gigantic ocean titan while seeping her corrosion into it, making it slowly decay into chunks, the souls of the three demigods could not be screaming in agony anymore!

"Infernal Blazing Fire Breath!"

"Slicing Claws of Slashing Storms!"

"Poisonous Deathly Blast!"

Marduk, Nanshe, and Nammu, the children of Kireina and Mady combined their attacks alongside their mechs potential and powers, releasing enormous attacks using all of their power, Marduk released gigantic breaths of fire that evaporated the oceanic giant's water, Nammu used her claws to release storms of slicing attacks, and Nanshe unleashed a downpour of purple energy concentrated into a large blast of deadly poison!

"Time to shine a little bit more, siblings! Divine Blood Beast Technique: World of Blood!" roared Habitis, converging her Divine Technique into her gigantic beast body and unleashing it as a world of crimson red, as enormous tentacles began to attack the giant made of water!

"I am feeling rather sleepy, but if we have to help out our family, I shall do it! Transcendental Bright Lion Queen Divine Technique: Lion King's Army!" roared Maahes, her gigantic lioness body glowed brightly in golden light, her Divine Technique converged into an enormous mass, as golden lions emerged, attacking the giant of oceanic water!

"Let us make this quick. Transcendental Shadow Wolf King Divine Technique: Wolf King's Army!" Ophois at the side of Maahes conjured a Divine Technique of its own similar to Maahes, by employing its own Divine Aura as the fuel, an enormous army of shadow wolves emerged from behind him, rushing towards the giant made of water and tearing apart several pieces of it, and alter on detonating into loud explosions!

Just by the attacks of Kireina's children alone, the three demigods were already faltering!

"Unleash everything!"

"All of our power… everything!"

"For father… and our mother!!!"

The three Demigods began to unleash even more power, wanting to avenge their parents with everything they had at hand, and concentrating their strength into the core of their fused souls, the giant's body strengthened momentarily, releasing gigantic punches and kicks into the ground, creating tremors, and sending away some of the enemies around them!

However, Kireina and her wives immediately entered battle!

"Divine Spirit Thunder Technique: Thunderous Battering Ram!" roared Brontes, rushing with her gigantic golden mech, raising the enormous club and unleashing a complete barrage of electrifying attacks over the giant, making it step back as enormous pieces of the fused gods souls began to fall apart!

"Transcendental Shadow Void Magic: All-Devouring Black Hole!" conjured Zehe, as she summoned a gigantic magic circle within seconds, enormous quantities of magic started to concentrate around the magic circle, as it approached the giant in an instant!

Flash!

An enormous black hole then emerged out of nowhere, beginning to absorb and devour a large mass of the giant, making it finally kneel as the three fused demigods could barely stand now!

"Rainbow Spiritual Domain: Transcendental Nirvana Blades of Judgement!" said Rimuru over her gigantic and beautiful mech, generating countless blades of iridescent rainbow spiritual energy, firing them against the giant and annihilating several chunks of it instantly!

"Transcendental Cursed Poisonous Axe Technique: One Thousand Poisonous Snake Bites!" roared Amiphossia, her mech was one of the biggest around, and her several arms wielded one gigantic axe each, unleashing a complete barrage of slashing attacks, tearing down the giant within seconds!

Clash!

The enormous giant finally began to fall into pieces, as Kireina and her fused wives flew towards it with all of their concentrated power, like a giant meteor of many colors!

"I will grab the Oceanus Fragment first though!" said Kireina, as she extended her gigantic metallic claws covered in her deadly Aura and grabbed a gigantic piece of soul, or various, in fact!

Clash!

"Ungggggaaaahh… Free me at once!" roared the fragment, as Kireina ignored him and saved it inside of her soul!

"Kireina!!!"

"We will not die without fightinggggg…!"

"DIEEEE!"

The three Demigods, Cabeiri, Cabeirides, and Thalia, converged all of their strength into a single point, firing everything they had against Kireina!

FLASH!

However, Kireina simply amassed an enormous quantity of her Aura, her pure Divine Aura, and shaped it as a gigantic maw, eating all of the blasts of power sent to her, as she quickly descended towards the core of the three fused demigod souls!

"I-Impossible, she's eating even that?!"

"Noooo!"

"There was never… any chance?"

"Now join your parents and become one with me, perhaps as my power, you might one day find redemption!" roared Kireina in anger alongside all of the voices of her wives combined into her, her gigantic body shaped like an enormous maw converged with her Aura, devouring the three Demigods in one single bite!

"UNNGRRYAAAAAAAAHHH…!

CRUNCH!

The conflict against the Hephaestus family… was over!
