City Of Shadows: Quincy Bloodstorm [WW4 Start Event] [Antarctica]

Stefan ignored his opponent's manual explosion of her spikes as Stefan's own attack did plenty of work ensuring little to no harm would come to his ally. While it was true the Shell's energy and chaos were volatile to say the least, his own unique Antimatter was definitely a match for it capable of reducing damn near everything to nothingness. Destruction was the name of the game while in Bankai and the retired Monsuta King would not allow his power to be overridden by some possessed clone such as this. His own incredibly potent and cold Spiritual Pressure would continuously fight against the Shell's, keeping her attempts at overwhelming the nearby Quincy woman at bay. While truthfully Stefan didn't really care all that much about what happens to his ally, figuring if she wasn't strong enough to hold her own then she should not have entered this fight in the first place, the quickest and simplest path to victory that would also make his deal with the Quincy leadership appear evermore desirable involved keeping her alive.

This faux-Mana just kept on saying everything Stefan found detestable in enemies, this time claiming to be a devil. "Devil? You think YOU'RE a Devil? You must not know who the fuck I am then. I'm the guy who kills Devils." Allowing this opponent to live on and continue it's trail of destruction was not an option for Stefan, a man who once reveled in bringing entire countries to their knees. Whether it was a change of heart or merely a result of wanting to be the mightiest warrior of all the realms in this bleak universe, on this day Stefan stood as a bulwark against the tides of darkness threatening the City of Light. Not for the sake of the Quincy people, not for the sake of the "greater good", and certainly not for the sake of redeeming his own self did Stefan now stand here. In this moment all that mattered to the man hailed as greatest swordsman alive was cutting down this one foe with extreme prejudice.

Despite the Shell's best intentions, being in close contact with Bankai-cloaked Stefan was also not a very good situation to be in for anyone. In fact, unlike Mana's energy and Madness which were more passive materialization of her being, Stefan's Antimatter was an offensive ability specifically meant to destroy whatever it comes in contact with. Like other Shinigami who's releases alter their clothing and very body, Stefan's Bankai veils the Vizard in a cloak of Antimatter with enough raw destructive power to even harm himself despite his ability to control it; for this reason attempts at having her energy maliciously affect or harm him would be met by this black and white cloak of Antimatter causing further destructive force to explode out from his body, drenching the battlefield in an inferno of devastation. If any of his Antimatter touched the Demon directly her own objective of harming him with her energy would rebound entirely, potentially causing further harm to her entire body without restrain.

Beneath the ever-regenerating jet black outfit of Antimatter Stefan wore in Bankai burns and immediately-cauterized cuts would spread across his arms and torso from the repeated explosions his power caused merely by coming in contact with his enemy's abilities. The pain coursing throughout his body reinforced the severity of the situation and battle Stefan currently found himself in. But he would not be deterred; the only solution was to continue on in this clash of gods until finally he could stand in the brilliance of victory. To stand atop another mountain of conflict and struggle was what Stefan Soan lived for, it was what drove him to become who he is now with all his power and determination. If anyone were to shake this world to it's very core, it would not be some imitation with a funny southern accent; it would be Stefan.

Along with this, if the faux-Mana thought she would be forcing Stefan to make a choice between defeating her or saving the Quincy people she would be sorely mistaken. With the exhaustion from fighting in his uniquely-tiring Bankai and pain from the injuries he'd both received and delivered unto himself piling up, the Grand Vizard spoke to his demonically mad enemy once again "You're powerful, that's true. I bet the real Mana would barely be strugglin' in a similar situation. But you're not the real Mana. You're an imitation at best, a sick doll needing to be put down at worst. But don't worry, by my blade I will deliver the euthanasia personally!"

Against the black backdrop of whatever this unholy pocket dimension could be categorized as, bright white energy began glowing across Stefan's trusty Zanpakuto Mugenkū; an energy so powerful and dense it put his previous uses of Antimatter to shame, clearly on a whole other level. One might wonder how this newest energy could even be considered possible while in Bankai and not some transformation even more extreme. Yet, the story did not end there. As the light grew and expanded until shape-changing into what appeared to be lightning, a counter to it also appeared along his blade's edge in the form of pitch black energy also resembling electricity. Between the two energies Stefan's arms matched only by one other person in the world in raw physical strength began shaking every so slightly as his mind also strained from the focus necessary to use this ultimate world-breaking technique.

The true name of this combination of techniques, known as Roaku, the Zanjutsu form of Shunko, and Raitongiri Imbue, the materialization of his Void on his blade, was called simply God Slayer; the ultimate attack Stefan had once used to great effect against Moonie Iramasha, nearly bifurcating the immensely durable fighter as a result. Merely by coating his sword in Roaku and Void simultaneously caused the sub-realm around them to shake like nothing but Mother Nature herself was capable of doing. Even the City of Light below, and truthfully all of Antarctica, could feel the effects of his God Slayer's existence as the continent would be drenched in a targeted pressure that would halt the demonic invasion in it's steps. This was no simple Bankai level technique as would be made clear by the sheer overwhelming density the energies involved possessed, akin to the deepest darkest depths of the Marianas Trench.

Using every bit of physical strength and mental focus available to him (both Grandmaster), neither able to be matched by anyone but a few select individuals across all realms, Stefan lifted his Zanpakuto above his head and swung it downwards in the Shell's direction, uttering "Begone!" as he did. The destructive force of the sword swing alone would be at the peak of what he could offer in Bankai, and would be reinforced incredibly by the sheer power of the God Slayer in both devastating output and speed. The entire attack would happen in an instant, leaving little time for anyone to react including his ally who remained but a moderate distance away. From directly above to below his feet the sub-realm would shatter like a window pane, utterly vaporizing it and leaving the combatants back in the real world above the City of Light.

As for the Shell, even through multiple layers of defense and barriers there would be little room for survival available to the possessed being. Even should she be capable of living through being cut in half directly down the middle, the following explosive pressure and electrical energy would tear away at the fabric of her being on a molecular scale until nothing but emptiness remained. The surrounding effects of her Reiatsu and Madness would be swept up by the monumental destruction resulting from winds unlike anything nature was capable of, likely sending Sophie flying away at such speeds she would find resisting against an extremely difficult feat; though Stefan doubted the Quincy would die even should she impact the ground like a meteor.

Stefan himself felt the reverberations and side effects of his own attack; thankfully the demon's earlier scream had dulled his hearing enough to prevent him from going temporarily deaf, though Mana's attack had indeed left blood running down the sides of his head. Still, what was currently hurting most was his arms; usually he would refrain from using such a powerful and exhaustive attack after already receiving injuries to upper body limbs, but it seemed the best course of action for this conflict. The Antimatter clothing which continuously regenerated itself using his energy found itself entirely stripped from his arms and torso as it struggled to rebuild itself in the wake of Stefan's God Slayer. Atop the Vizard's strong and robust muscles was badly damaged and hurting skin, revealing the consequences of this battle. Along with this was noticeable exhaustion causing his arms and legs to feel heavier than they'd felt in a long time. Yet there was no frown or grimace of discomfort on his face, no indicator of pain or struggle. Instead Stefan's mouth was turned upwards in a smile.

"Thanks for making me fight harder than I've had to in a long time. You may have just been an imitation, but to undervalue your power would be an injustice. Now rest, demon shell; I come for your true self next."
