Vampire Summoner's Rebirth: Summoning The Vampire Queen At The Start

-----

Satan's enormous blazing fists descended towards Elizabeth, the young Saintess conjuring several barriers made of holy light to defend from the blows, although they were so potent that her shields were easily destroyed with a single attack.

BOOOM! BOOOM! BOOOM! BOOOM!

As the almighty attacks were about to reach Elizabeth, a gigantic slash of pure golden and green light emerged from the skies, Erika appeared above, swinging her Greatsword!

"[Yggdragon's Blade]!"

SLAAAAASSSHHH!!!

The slash shaped itself into an almighty dragon made of golden and green light, slashing through the various fists made of volcanic rock, flames, and demonic energy!

"UUURGGHH…! ANNOYING PEST!"

Satan monstrously roared, his entire body shapeshifting into countless of spears, firing blazing spears everywhere! Elizabeth and Erika swiftly unleashed their magic and techniques, slashing blows and explosions of light intercepting the deadly projectiles.

CLASH! CLASH! CLASH! CLASH!

At the same time, above Satan, four gigantic dragons were becoming one, their essences, powers, and souls were combining together. Blake could be seen from a distance, waving his hands as his Mana flowed out of his body almost endlessly encompassing Ruby and the four other Frost Dragons, which were on their very last breaths!

"[Fusion]!"

FLAAAASSSHHH!!!

"HUH?!"

Satan glanced into the direction of the light, his blazing eyes filled with disbelief as he saw the tiny lizard that had annoyed him beforehand grow to a completely enormous size, easily surpassing over a hundred meters of height!

"ROOOAARRRR!"

Ding!

[Through the powers of the [Fusion] Skill, you have temporarily fused the four Fusion Familiars [Juvenile Frost Dragon: Frost (B Rank)] into the Tamed Monster [Demonic Blood Dragon: Ruby (B Rank)]!]

[Ruby] has undergone a temporary transformation, becoming the [Demonic Frost Blood Dragon King (A Rank)]!]

[The stability of this fusion is surprisingly stable! All of [Ruby] Stats have merged with the Four Fusion Familiar Stats total, while sharing their Skills, and gaining an additional +100% to All Stats!]

[Ruby] exudes a mighty [Blood Frost Draconic Aura] around his surroundings, decreasing the Stats of all Foes by -30%, and constantly freezing their bodies, chipping away their health and energies!]

[Transformation Duration: 10 Minutes.]

Ruby had temporarily fused with the Frost Dragons, undergoing an incredibly transformation, as he gained these dragons appearance, covered on sharp frost crystals, while his scales became frost-like, and his wings gaining a second new pair!

"Go nuts, Ruby. It's your time to shine."

With Blake's commands, Ruby descended towards Satan, clashing against his gigantic, blazing body with a tremendous explosion of ice, darkness, and blood!

CLAAAAASSSSHHH!!!

His sharp claws slashed through Satan's body, constantly freezing him further and further, his body beginning to slowly fall apart into pieces! Ruby didn't stop there, as Satan desperately attempted to regenerate and fight back with his fists and explosions of Wrathful Flames, Ruby kicked its arms and destroyed them, while its mighty spear tail pierced his body countless times!

CLASH! CLASH! CLASH! CLAAASH!

"RAAAAHHH!" Satan roared, furiously opening his enormous mouth, and releasing a downpour of blazing wrathful flames, only for Ruby to tank them head-on, opening his jaws instead and releasing a mighty breath attack of freezing blood and darkness!

BOOOOOMMMM!!!

The explosion between elements shook the entire ruined city, Satan's entire body constantly crumbling, only for him to regenerate anew almost right away, unleashing a barrage of punches against Ruby, who the dragon mightily took head-on, receiving barely any damage!

"SHAAAAH!"

Hissing like a snake, the dragon conjured dozens of magic circles, releasing a tempestuous, swirling gust of freezing crimson winds and darkness, consuming a part of Satan!

FLUOOOSH!

Satan responded by opening several eyes across his body, firing beams of red lasers, clashing against Ruby's body, and pushing him back constantly, only for the dragon to rush back, kicking it, slashing it, and piercing it with his legs, claws, and tail!

It felt as if both were on a stalemate! However, Ruby's transformation could only last ten minutes, everyone else could not simply sit and watch, hoping for Ruby to do all the work!

Elizabeth and Erika opened the way for Ruby strike further into Satan's soul, Erika swung her blade several times, her wood was useless against these flames, but her other powers, such as Illusion Magic combined with her sword techniques and draconic energy were amazing!

"I guess there's no helping it!" Erika roared. "[Spirit Fusion]!"

FLAAAAASSSH!

And even more once she underwent Spirit Fusion with her Dream Dragon Doll, her entire body suddenly undergoing an amazing change, as she grew very tall, as if she had aged into her early twenties, her long pink hair waved across the wind. 

Enormous, pink-scaled wings grew from her back, a long spear-tipped pink tail, and golden horns emerged from her forehead, all combined with a second pair of scaled arms, with sharp claws!

"Amazing…" Blake said as he admired Erika's Spirit Fusion, her powers growing vaster.

"[Dream Dragon Clone Illusion]!"

She quickly materialize dozens of illusions that near identical to her, appearing all around her surroundings, as she clashed against Satan's many arms and claws, her clones being materialized and physical, as each of their strikes slightly cracked Satan's soul a bit more!

"[Spirit Weaponization]!"

At the same time, she weaponized not only her many dolls to unleash a barrage of weapon attacks, but also transformed her Black Knight Puppet into a mighty black accursed sword, which helped her dual wield with her original sword, her blows becoming even more devastating!

CLASH! CLASH! CLASH! CLASH!

At the same time, Elizabeth channeled the powers of her Spirits too, fusing with her Holy Dragon Spirit, the partner of Ellergest that he had inherited to his daughter, while the rest of her Spirits combined into a mighty golden hammer, smacking, and hammering down her foe.

BAAAM! BAAAM! BAAAM! BAAAM!

At the same time, Blake's friends were moving on, a Half-demon boy beginning to gather all his strengths, as his skin slowly changed color to a deep red color, black tattoos emerging and turning his skin into charcoal black, as he was swiftly covered by golden tattoos now, each transformation boosting his stats and physical prowess even further!

"Prepare yourself, you bastard!" Erdrich roared. "[Heavenly Demon Battle Arts]: [One Hundred Ashura's Fists]!"
