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

-----

An enormous red dragon dropped into the ground, its gigantic, over 200-meter big body was dead at long last, covered in thousands of wounds, missing its two wings, two of its front legs, and the eyes being crushed so it couldn't see, making it easier for the ones fighting him to kill him. Atop the head of the enormous, red-scaled dragon, there was a beautiful lady with blazing red hair and crimson-red eyes, pale white skin and black armor holding into a large, five-meter-long blade piercing the dragon's head.

"Phew… That was… so tiring… I guess this is the last one!" She said. "Ah, I wonder how are main bodies doing? It has been a while since they communicated with us."

A young boy on his late teens spoke to the woman from below, his eyes were gold and he had long white hair, while wearing light-weighted white armor.

"Veronica, are you done?" He asked. "Come down…" 𝘧𝑟𝘦𝒆w𝚎𝙗nov𝘦𝗹.𝐜o𝓶

"Eeeh? Come on, let me enjoy the feeling of victory! It has been a while since I felt this good, this damn dragon destroyed an entire city! Do you know how much pain was to kill this bastard?" She sighed. "Well, he's deader than dead now, but still…"

"I know how you might feel, but it's over now, the dungeon will be destroyed with us included inside if we don't walk outside in time…" He said.

"Right! Alright, Kireina! Where is she?" Wondered Veronica.

"She's there." Said the boy, Ervas.

"Nom… Nom…" A girl resembling a beautiful… monstrous mass of flesh with many tentacles and jaws continued to devour a pile of lesser dragons and wyrms, she seemed very hungry.

"Oh? Right, sorry…" She said, quickly turning back into a hot blonde fairy, with green wings and blue eyes…

These three characters that were somewhat similar to our protagonists were in fact their clones, weak fragments of their souls and flesh left in the world of Kosmos to destroy the dungeons left behind by the System Master, an enemy of the past that had decided to ignore this world after the events with Hekaton in Kritias, but that he had left the System, and the Dungeons without bothering to take them away.

It was the duty of these fragments of our protagonists to clear these dungeons with the aid of the Greek Gods with them, such as Nyx and Hades, who were not present here, but that had helped them through their journey until the ultimate boss fight against the Divine Flame Dragon Emperor, Asura, a monstrous and intelligent dragon that was born from the strongest dungeon in this world, who had tormented an entire continent for years.

He was finally chased down when the trio gathered enough power, and then ultimately slain after an epic battle that lasted over a day… They had to go all out against him, but they managed to defeat him at the end.

POOF!

And then, as they were talking about moving out of the dungeon before it destroyed, several enormous spheres of red crystal emerged in front of them, these were Cores, special items that dropped from monsters inside the dungeons created by the System Master.

When Absorbed, these crystal spheres granted an increase in Stats, making them stronger, they had been absorbing them as they defeated monsters and the bosses of these wicked dungeons, freeing the Greeks from the menace of these monsters. Although their journey had actually taken a few years, and monsters that had escaped the dungeons still roamed the world and multiplied, becoming common place now, the world was in a much better place now.

"These crystals… Let's absorb them and get out of here quickly then." Said Veronica. The group quickly agreed, absorbing the crystals of enormous sizes, and then gaining an even greater increase in their stats. The world of Kosmos was being governed by a mysterious system left by the System master, which let anyone absorb crystals to gain stats. Of course, they were quite limited, and after absorbing enough crystals and reaching a new rank, stronger crystals would be needed to absorb them and gain more power. There were also Ability Crystals, which were also absorbed by the trio to gain new and interesting Skills through their journey.

Quickly teleporting outside the dungeon through a special structure that led to the outside when a boss was defeated, the trio was greeted by the desolate landscape where the dungeon was located. Veronica had brought the corpse of the dragon to make it into an Undead, although for now she was a bit tired to do it yet.

Crack… CRASH!

However, as they were about to go back to town and relax, they heard cracking sounds, the sky suddenly began to open, as if a crack in a glass appeared, the trio was left surprised. Just what was happening now?

"T-The heck?" Asked Kireina.

"Wait a second…" Said Veronica.

"Huh?" Wondered Ervas.

CRAAAASH!

Atop the skies of the world of Kosmos, a dimensional crack emerged! The Gods all across the world suddenly felt the enormously loud event, Zeus who had grown more fond of the trio now that they had helped the world so much suddenly woke up from his nap, glaring at the skies to see what he couldn't even believe.

Nyx and Hades who were drinking some tea in the Underworld, heard the cracking sounds and went to the surface, quickly emerging behind the trio of heroes from across a portal made of bones conjured by Hades.

The other Gods spread around the world, and even the confined Titans could see what was happening, all of them looked into the skies, humans, animals, monsters, gods, all of them did the same at the same time, for once in history.

"A crack in the sky…?" Asked Zeus in disbelief.

"What is the meaning of this?!" Asked Veronica.

"I-I have a bad feeling about this…" Sighed Hades.

"Wait a second, is this…? It can't be… This enormous quantity of Soul Attribute Energy…!" Said Nyx.

"Eh? Wait… They're here?!" Asked Kireina in disbelief.
