As Brunhild and the twins believed their foe was soon to be defeated, the power of the cosmic stone fragment he was carrying with himself activated! The tremendous power of the cosmic energy quickly caused a monstrous mutation in the Necrotic Death Lord's body, turning him into a monstrous, aberrant mass of bones with no resemblance to his sleek and rather gallant previous appearance.
His single poisonous sword melded into his bony jaws, turning into sharp black fangs reeking with this deadly venom, as a long tail with the shape of a spear pointed at the trio, unleashing a barrage of attacks without giving them any time to react!
"DIIEEEEE!"
CLASH! CLASH! CLASH! CLASH! CLASH!
"Unnggh…! I have to combine these elements together…! I…! [Heavenly Phantasmal Barrier]!"
FLAAAAASH!
Suddenly, Brunhild combined two elements that could never get along, Heavenly Light with Death and Phantasmal Elements, fusing them even against the elements very wills, and forming a powerful, gray-colored barrier of light and darkness, which shielded her and the twins from the constant attacks!
CLASH! CLASH! CLASH! CLASH! CLAAASH!
Crack… crack!
The barrier, however, even when made of these two powerful elements, could only hold for so long at Brunhild's current state. The poison, albeit slowed down, was still hurting, and rotting away her insides.
"Damn it…! DAMN IT!!!" Brunhild cried, tears flowing from her eyes, as she recalled her life until now.
Her village, her father, her mother, and the promise she gave to her father that she would come back, stronger than ever before to protect her village. She recalled what she had heard of her mother, and all the things she accomplished.
Was she destined to die protecting those she loved like her mother did?
Yet… something even more primal within her bloodline slowly started to awaken, within this state where her body was being pushed to her very limits, while a deadly otherworldly poison ate away her body's life, and while she was at the verge of death…
BA DUMP!
Her heart started beating faster, and faster, and faster! Brunhild's muscles started to grow larger as well as her size, her veins started to get bigger and showed all over her body, and a mystical power started to emerge from within her heart.
"Unnggh…! AAAGGH…!"
"Brunhild!"
"Resist!"
The twins panicked as Brunhild felt an agonizing pain all over her body, her heart was beating faster and faster. The twins thought she was about to die, growing desperate and summoning the power of all the Holy Spirits they could, combining them with the Death Spirits and forming…
TRUUUUUMM…!
Strange, purple and black colored spirits resembling octopuses, or twisted masses of flesh, or just floating, red-colored eyes. These spirits emanated a power very similar to someone they knew… Kireina!
"T-These are…!"
"Chaos Spirits?!"
The twins put everything they had into this attack, generating a gigantic mass of Chaos utilizing the Chaos Spirits aid, and then shaping it as a deadly sword!
"Chaos Spirit Magic: [Primordial Chaos Blade]!!!"
SLAAAAAAASH!
The massive blade emerged, piercing through the gigantic skeleton monster that the Necrotic Death Lord have transformed into, and then slashing through his entire body directly!
CRAAAAAASSSHHHHHH…!
"GRAAAAAAAGGGGHH…!"
The monstrous Bone Chimera was sliced in half, both of his halves beginning to leak large quantities of cosmic and necrotic energy, before the sword exploded!
BOOOOOOOMMMM!!!!
However, even after an explosion that would had consumed most foes, the monstrous bone chimera remained flying! The cosmic energy of the cosmic stone fragment generated countless threads, slowly beginning to unifying the two halves, as the furious chimera started roaring furiously, biting through the twins' defenses!
"RAAAAAGGGH! IT WON'T WORK! GRAHAHAHA!"
CRASH! CRASH! CRASH! CRASH!
Crack… crack… crack…!
The barrier continued shattering, and shattering! The twins had no strength nor mana anymore, and were about to fall unconscious due to the venom, while Brunhild kept screaming in pain.
Everything was over!
CRAAAASH!
The barrier finally broke, as the gigantic skeleton chimera neared its jaws, about to eat the trio in a single bite!
"I SHALL FEAST ON YOUR DAMNED SOULS!!!"
"Uuuuaaagggh!"
"Nooooo!!!"
As Brunhild heard the screams of her friends, something deeper became to awaken, filling her entire body with an intense amount of heat! The weak physique she had somehow was brought to its limits due to the venom, forcing her physique to either adapt or die.
Since she was born that Brunhild's body was physically weak. Some thought it was a curse that witches had. But it seemed to be an after effect of her immense magic potential. A defect that her mother also shared.
Yet… in this very specific moment, as she pushed to her limits until nothing else were to remain in her body, is when this power was born, or well, it was where it was hiding this whole time. Kireina knew it very well, many times she pointed this out.
"You know? I know a lot of other Giantesses out there, but you're quite special. I know it, I can sense something inside of you, girl. You have yet to truly awaken that power."
Indeed, the true strength of a Giant- no, a Titan!
TRUUUUUUMMMMM…!
A gigantic, fifty-meters-big fist emerged above the twins. Their eyes filled with shock as they simply couldn't believe what they were seeing. Brunhild's size had suddenly become ten times as bigger, and her fists were utterly titanic!
CRAAAAAAASSSSHHHHHH!!!!
"GRAAAAAAHHHHH…!"
The Necrotic Death Lord was completely blasted into bone pieces, as Brunhild's furious Titan Fist hit him with all her strength, pushing him down into the floor below, as the sands shook and every undead in the vicinity turned to ashes after being bathed in the shockwave.
"U-Unngggh…! W-What…! What is this?!"
The Necrotic Death Lord phantasmal soul remained, as his bones slowly began to recombine, his phantom eyes glanced at the scene of a giantess falling over him with horror!
"W-Wait!"
BAAAAAMMMM…!
Brunhild's gray skin suddenly gained countless magical runes all around her body, which began dancing with many elements together, generating a beautiful rainbow arc behind her back. Her fists erupted with elemental magic divinity, destroying the Necrotic Death Lord with each fist!
"RAAAAAAAHHH!!!" Brunhild lost her mind in this form, screaming her lungs out as she completely demolished the Necrotic Death Lord into smithereens!
"T-This is…! It can't be…! Is she… the Descendant of…?!"
BOOOOOOOOMMMMMM!!!!
Amidst his own disbelief, his very existence was annihilated before he could even come to a conclusion.
