A New Life, Beyond Realms: Tensura x Overlord

The heavy and weighted great sword cleaved the air in half as the sharpened blade whistled in its movement. A loud war cry bilged from Yuna's mouth as she came down onto the chest of the Dragon with the force of an anti-tank rocket. 

"ARRGHHH!... SMALL INSECT!!!" The Dragon flapped its wings in her direction with immense force, her legs lifting off of the ground as she was thrown into the far wall of the cave. Then the dragon opened its toothy maw, revealing hundreds of jagged sword-like teeth that oozed in saliva. The liquid froze rapidly however as an ominous bright cyan radiance began to quickly flicker up its long neck. When the light filled the entirety of its cavernous mouth did the content spill out, a frost so concentrated and powerful that it froze the air itself. 

"Shit! SHIT! SHIT!" Carrera leapt for the side of the cave, using her psychic powers to yank herself forcefully at the walls. Meanwhile, Nyx rose a massive barrier of hell's flame, the heat enough to boil oceans and souls alike. Testarossa made the action of pulling a bow despite not having one, magic taking its place as runes of the darkest shadow emerged.

"Yuna, you just had to poke the fucking thing! HAH!" With a powerful exhale of breath the runes exploded out into a singular missile of pure darkness, wreathed in tentacles of purple curse energy.

The Frost from the dragon met the hellish wall of flames as the shadow arrow cracked against the hide of the dragon, the tentacle desperately attempting to cling to the spaces between the scales. A guttural croaking began to emit as the Dragon snapped its maw closed, the eyes immediately narrowing down onto Carrera who looked the most exposed currently. Said woman was covered in thick ice as the tips of her hair was stuck in the movements it has been subjected when she dodged.

"INTRUDERS...! WILL TURN INTO MEALS...! BECOME MY MEALLLSSS.....!" Ice exploded out from the wall that Carrera was using to get back up, piercing into the side of her body as a yelp escaped her lips. Blood dripped from her side onto the frozen ground, turning into icicles half-way through the fall.

"Fu-Fuck... Help! Please...!" At this moment a sword travelled from the most distant cave wall, the weapon quivering in mid-air with the sheer force used to thrust it through the air. The tip created a conical projection of air before it, the weapon instantly traversing the distance to slam into one of the Dragon's eyes.

*AUUUURAGGHHHHHHHH!!!!!!!!!!!!!!!!*

The wild dragon reared back onto its back legs as draconic blood plopped from the freshly made wound in its right eye. Ice within the cave began to manifest deeper frost, atmospheric conditions turning blurry white as the very air itself was having a hard time retaining its' gaseous form. Nyx, not wishing to let this chance get away from them, stepped out from the flame wall, banishing it as her hands rose up in front of her. Palm to palm the hands rotated clockwise before hundreds of small incandescent lights started to flicker around her entire body. Like fireflies these lights danced playfully. Then, as the spell began its dance she separated her hands forcefully outwards in the direction of the white dragon.

"Fade into dust you wretched beast."

The lights all intensified into what seemed to be miniature suns, their photons close to that of a flashbang if it were hundreds of times more effective. All of these lights, if one could see past the flash, began to gathering into a larger construct of magic. Glowing with red eldritch light this construct simply blipped out of existence for a second.

*PSSSSSSSSHHHHHHHHHHHHHUUUUUMMMMMMMMMMMMMM* 

A sun of magic dropped onto the head of the dragon as the frost around it hissed in violent reaction. Steam began to consume the space before all of it was burned away further, the explosion of steam being prevented by the apocalyptic levels of heat. Sprays of fresh ice and frost struggled to shoot our from the barely visible dragon as its scales slowly popped and cracked, the entirety of the hide boiling under the intense stress of the spell. Unfortunately the spell soon faded however, the dragon slumped into the ground but still alive as its singular eye hatefully glared out at all of them. The creature's nose flared in quick succession, taking less than a second each intake, before it struggled up to its feet.

The downside to this spell was the flash, Nyx's allies being incapable of currently responding as they regained their vision. Efficient member of the adventurers that she was Nyx stepped forwards once again, her eyes glowing with void-like purple ichor as her hands began to arc upwards once again...

Before anything could be done by her though a prayer of sorts sung into the entire chamber. "Goddess of Dragons, defender of us chromatics and sower of Chaos, please smite down these gnats that have invaded thy home!" In Draconic the dragon sung out, its head arching upwards as if beseeching something higher than itself. 

*Ooooohhhhhhhh...! AaaaaaAAAAaaaahn...!*

Music began to filter into the chamber as chaotic crimson bursts of light dripped down into the cave. Magic swirled and grew to a fever pitch as the four women could swear that the eyes of some creature were barely visible out of the corner of their eyes.

~The companions of my brother~

A melodical voice boisterously sung down into the consciousness of every creature present as the crimson swirls of magic coagulated into a small misty representation of, something.

~Your request has been declined. Retreat from this cave and give them your treasure~

The figure turned its form to address the critically wounded white dragon, a shiver running through the Dragon as it dropped its head to the ground acquiescence. No words were heard from it, no sounds screeched out, not even the gnashing of teeth... Just as simple lowering of the head...

~Good. You shall be rewarded by an increase in position. Be happy that these intruders had come to your cave. Instead of another's~

"Yes, mistress. Your word is law. I thank you for thine position."

~Be off now~

It nodded its head before flapping its weary and damaged wings, launching itself backwards off of the platform and twisting its body away from the adventuring group. Meanwhile, a sword still dangled from the right socket of the dragon, stuck there deeply into the sinew and flesh of the dragon.

"Hey! That was my sword...!" Yuna ran forwards for a few steps until Testarossa and Carrera held her back, Nyx taking a step back in their direction. Whatever had just sent that beasty away was much more powerful, based upon how the dragon had just responded.

~These are the companions my Brother keeps now... Intriguing. Tell me, what are your names?~

Red mist just swirled in place, five feet tall and vaguely shaped like a dragon.

"U-um... Brother? I am afraid that I don't know...-"

~You would know him as Silviana~

"Silviana has always been a woman though!" Nyx stood out now, her purple eyes locking sights with this red mist of unknown origin or power.

~Mmmm... For you, yes... Regardless, what are your names?~

"My name is Yuna! This is Carrera!" Carrera gave a confused and dumbfounded expression as Yuna took her hand and rose it upwards. "And... This is Testarossa, she's really beautiful although she tries to hide it." Rossa blushed but then blinked several times, trying to slap Yuna's hand away as she took her arm and rose it upwards. "The one in front of us all is Nyx, she's a bit uptight but is really, REALLY, cute." Nyx deadpanned but still faced their opponent, her posture tightening just a smidge in response to the comment 'cute'.

~Ha... Hahaha... Hahahahahahaha... You are very unique!~

Yuna shrugged. "It's what I get for being a sister of Silviana..." She laughed after finishing her statement, the other women in the room tensing as the red mist condensed more, forming nine distinct draconic heads of mist that all slightly glimmered with different colours.

~Sister you say...?~

"YEP! She confirmed it after we fought together and saved every soul from our past world!" Nyx fully facepalmed at that moment as Carrera stared blankly at Yuna, her expression hard to describe as it was somewhere between angered and blown away. Testarossa wasn't even paying attention as she continued to blush, her hands playing with her clothing despite her best efforts not to.

~Is that so?~

"I just said yes...?" Yuna turned her head and put a finger on her lips whilst gazing at this expanding but contracting mist.

~P-Pahaha! Yeah, you'd definitely be someone he'd find to be a sister or something! You have that air headedness about you that is not too dissimilar to Lolth when she was not Lolth...~

Yuna just inclined her head in confusion.

~Well, you have given me your names. So, I shall give you my own.~

Darkness welled within the cave, shadows crawling and creeping with immense power. Whispers seemed to blither in a cacophony around the four women of Tempest. Winds whipped upwards in speed as their power sheered away hundreds of ice fragments that had grown thick on the walls. The red mist darkened and gained a rainbow-esque hue that represented the powers of this being, this entity.

~YOU HAVE MET WITH THE DRAGON GOD OF CHAOS, ELEMENTS AND DRAGONS! TIAMAT!!!~

Thunder boomed around the entire cave as Carrera, Rossa and Nyx all dropped to their knees and buckled. An earthquake seemingly jolted the entire mountain as ice fell from the ceiling only to be swept away by the grinding torrent of wind that shredded them into atomic versions of their previous selves.

"Nice to meet you! Would you like to be my sister or brother as well?" Yuna held out her hand for a handshake, the entire display being discordantly interrupted by her offer.

~.......................~

"""........................"""

Tiamat and the trio of women who were there to witness Yuna saying this all just froze. Confusion subverted everything and by the time that what she had said was understood the entire powerful display was quelled into a subtle hush... As if someone had merely farted.

~...S-sure...? W-wha-what is going on here?~

' ' 'Don't look at us!!!' ' ' Carrera, Rossa and Nyx all thought at the same time as the floundering Dragon God glanced between them and Yuna rapidly.

"YAY! Another, sister...? Ah! Who cares! Another sibling!"

Yuna started to rejoice as just before her a sword of deep crimson-black grew from the very ice in sticky tendrils of dragon blood and flesh. Liquid hardened and became coarse as mushed scales started to emerge from this hardened outer-layer. A blade of a living dragon, a weapon forged from the bond between a Demon Lord and a Dragon God of Chaos.

"What'd ya get!?"

"Mmm, what is it?"

"Not interested."

"I GOT A SWORD...!!!"

~......~

~How???~

Yuna celebrated as the sword flung itself into the air and began to dance in mid-air, end over end, as if celebrating along with her about its existence.

~"""What the fuck?"""~ Everyone besides Yuna had this exact thought at the exact same time...
