Demon Queen Rebirth: I Reincarnated as a Living Armor?!

-----

Erebus, the personification of darkness on Greek myth, a powerful Primordial God that often was said to be a titan, and other times even beyond that. His power was only comparable to entities such as Uranus and Gaia, beings that embodied the heaven and the earth, or even the powerful Tartarus, who personified the underworld. All of such Primordial Titans, as they were named, inhabited the depths of the world, the last horizon within the three layers, the underworld, the earth, and the heavens. And Erebus… was not alone.

With him were his sealed companions. The titan that was trying to infilter the depths of the world of Kosmos was suddenly surprised, the entity that was beyond the Celestials, capable of devouring entire stars, had his arm completely engulfed by this eternal darkness!

"GRUUUAAAAAHH…!"

The wild Primordial cried, slowly moving backwards in horror. The undead and other specters of the underworld could not affect him, and only died crushed by his foot, but whatever was in the depths of the Last Horizon, the fourth and forbidden layer of the world of Kosmos, was certainly someone formidable.

"Erebus, stop messing around, why did woke us up?" Another voice resonated; it was slightly similar to that of Zeus.

"I am so sleepy… It is not yet the time for us to rebel against the Gods yet…" Sighed another feminine and slightly mature voice.

"There is a literal alien invading my domain!" Roared an angered male voice.

And from within the depths of this darkness, three enormous titans emerged, bathed in the darkness that didn't seemed to affect them. They looked incredibly basic in appearance. One was composed of blue winds and clouds, as if he were the sky itself, the other was an enormous titan made of stone in the slight shape of a mature woman, and the last one was a being covered in spiraling darkness and armor made of black and gray rock, with fiery red eyes covered with flames.

Some of the undead in the distance looked at these formidable entities, without being able to believe it with their very dead eyes…

"T-That's… I can't believe it, Uranus, Gaia, and Tartarus!!!"

"And that darkness behind them… It is Erebus, isn't it?!"

"The Primordial of Darkness, Erebus?!"

The Primordial Titan sent by Samsara was left speechless due to the aura of these entities, just when it thought that it could finally grab the item that his master wanted, these powerful elemental beings emerged!

TRUUUMMM…!

Enormous spikes of earth emerged from depth within the underground, suddenly impaling the giant's foot, keeping it on place.

FLUOOOSH!

An enormous storm of winds captured his torso, without giving it the time to move around or try to defend against such an imposing force.

"GRAAAH!" The Primordial Celestial roared, as from within his body, countless beams of concentrated starlight and soul energy came out, piercing through the entirety of the Underworld and leaving destruction everywhere!

BOOOM! BOOOM! BOOOM!

"You bastard… Stop damaging my body!" The titan made of darkness and gray and black stones ran towards the Primordial Celestial, as his hands were suddenly engulfed in phantasmal flames, and he hit the gigantic Primordial Celestial in the face!

CLAAAASSSSSHHH!!!

The enormous being flew through the air, falling over a river that was transporting souls around and splattering the souls everywhere alongside any phantom in the vicinity!

SPLAAASH!

"GRAAHHH…!"

The Primordial Celestial roared wildly, unlike his weaker siblings, these enormous beings lacked a lot of intelligence, and were more like drones that were being controlled by Samsara than anything else.

However, it didn't meant that they didn't inherited the cunning nature of their father. The moment the Primordial Celestial noticed the river of souls, it touched the river with his hands and began to absorb the millions of souls crossing through it, gaining new power!

"That bastard is absorbing the souls of our world!" Said Gaia angrily.

"Uggh…. I don't know if I can fight more, after Cronos beat me, my power has been very low…" Sighed Uranus.

"Likewise…" Sighed Gaia. "Tartarus, Erebus! Do something!"

"If I go too outside of my domain, I will take a lot of damage." Said Erebus. "It's up to Tartarus."

"Of course it's up to me, he's stealing MY souls after all!" Roared Tartarus, a rather temperamental Kosmos Primordial, as he ran towards the Primordial Celestial and hit him with his fists in quick succession, a barrage of punches enhanced with the power of the underworld and the divine phantom flames began to cover his foe, as his entire body began to be damaged!

"GRAAAAH!"

However, the Primordial Celestial was not so weak! After having absorbed millions of souls in just a few seconds, his power was enhanced several times. The monstrous being managed to tank the hits from Tartarus himself, as he punched the Primordial of Kosmos in the face! ｆ𝘳e𝒆w𝗲𝐛𝘯𝐨νe𝚕.cｏ𝓶

BOOOMMM!!!

"Uaagh…!"

Tartarus' entire face exploded into pieces, as his gigantic body suddenly fell into the ground!

BOOOM!!!

"T-Tartarus!" Cried Gaia.

"Impossible, it overpowered Tartarus with a single punch?! Just how strong do absorbing souls make these beings?!" Asked Uranus.

"Gahahaha…!" The Primordial Celestial laughed like his father Samsara, extending his entire body over the body of Tartarus, which was still alive but unconscious, and suddenly absorbed him completely!

TRUUUUUMMM…!

"W-What?!"

The Primordial Kosmos Titans looked in horror as the Celestial absorbed the power of Tartarus and forcefully devoured him, acquiring his powers! Now, an armor of black and gray stone covered the Celestial, and it now possessed a pair of spiraling horns and phantom flames covering his fists.

Samsara smiled wickedly within his Domain; his child had managed to turn the tables on his favor!

"Now devour the other Primordials and gain more power and bring me the Primordial Origin Fragment after that!" Laughed Samsara, forcing his son to move.

The Celestial of titanic proportions quickly started to rush directly towards the Kosmos Primordials, with the intention to fully devour their powers.

However…

CRAAAASSH!

An enormous hole opened within the ceiling of the Underworld, as a titanic chimera beast roared, falling down right above the Celestial.
