He was growing resistant.

Quickly.

Despite my own, or rather, Aizen's own haphazardly thrown Kido spells and sword-swipes, growing in power with every direct hit- To the point of leaving scars and marks on the werewolf/demon fucker hybrid-

Evil Ichigo.

Let's just call him Evil Ichigo.

Evil Ichigo, for whatever reason, the moment I seemed to finally pierce the rest of his skin, suddenly started matching my own rate of growth- Or rather surpassing it, to the point even Aizen himself had started feeling hints of dread at the realization.

His speed and power behind each strike seemed to follow the same path.

Every time I damaged him, sufficiently, the werewolf simply healed it up via advanced, bullshit, regeneration, and grew stronger from it.

He was literally pulling a Goku on my ass via with his own brand of a Zenkai boost.

Worse, even the hollows currently holding up the spell field surrounding me seemed to follow the same logic, their own scales, reiatsu, and appearances growing along with him.

grunting once, I immediately ducked to the left in a feint, before promptly skewering my blade forward in a point-blank attack, only to throw a curse as the primordial fucker disappeared out of sight, reappearing metres into the air, his body twisted upside down as his hands covered his face, rocketing the ground whilst covered in his chaotic reiatsu.

Flash-stepping out of the area, I promptly covered my face with both arms as a mighty explosion rang out from the attack, pushing me further back towards the forcefield as my skin ached and burnt from the after-effects.

Josh Groban's form didn't hold up as he immediately rolled into a hunching position, his face and arms angled towards me as he rocketed off the grounds towards me. The speed was enough to catch me off guard as my body immediately started spinning in the air as an after effect, my shoulder dislocating from the sudden charge.

Not giving me another chance to react, I watched as, practically muted, the hollow promptly started charging up a point-blank cero at me from the ground-

Cursing once, I immediately held out both hands, suspending my body in the air as black walls immediately surrounded me, covering me from the attack. The drain on my reiatsu noticeable as the Hollow's cero washed over it, cracking it in the process.

Flash-stepping behind the now somewhat tired hollow, I immediately swiped for his neck, only for my eyes to widen as I watched the blade rebound of the skin.

With another mock-filled roar, I flash-stepped out of the way of the hollow's sudden outstretched hand- before wincing in pain as the sonic-boom set off by the punch pushed against me.

When the hollow teleported behind me again, I, in a moment of pure instinct, covered the sword in reiatsu and raised it to block the sudden swipe at the back of my head. My own shock at the fact the fucker's attack seemed to slow down the slightest at the contact, hidden.

The moment his eyes took note of what had just happened, the Hollow immediately building up another Cero, I lashed out with the reiatsu covered blade and struck the middle of the building ball of chaos. The sudden implosion covering the two of us, as my body was sent rocketing away again. This time in more pain since I'd first showed up in this crazy-ass world. My left limb loosely hanging by my side as my feet buckled to stand up straight.

To my surprise, however, Josh Groban's form seemed to be in even worse shape by the sudden bleeding scars that covered his body.

My eyes momentarily narrowed as I watched him heal up the wounds, the faint hue of red and blue reiatsu coursing through each scar as it covered them.

He wasn't Zenkaiing after all.

He was just adapting to whatever I threw at him...

I almost couldn't help the ghost of the smile that filled my face at the thought.

He'd been trying to end it quickly, or at the very least, delay the fight long enough until I threw enough at him that he'd become relatively invincible.

And judging by the sudden widening of his own larger eyes, I had a feeling he'd realized what my expression meant.

Unfortunately, however, the whole situation had turned out to be more of a mixed bag of news.

The good news was, the force-field preventing me from just running away had disappeared, including the legion of hollows that had them. Each one glowing a very bright red as their bodies sparkled the fuck up.

Bad news, the reiatsu that made them, and kept the field up was now instead converging into a single, very condensed point above the primordial one's head.

Checking over my options for the moment, I briefly fought the urge to immediately attack and stop the attack from forming, and/or straight-up run. Maybe even in that order.

Instead... To Aizen's complete horror and worry, I let it build up, calmly pulling the sword back to my left as my knees lowered themselves into a stance.

The only way to deal with a constantly regenerating monster after all was, well, from my only experience of anime, was the Majin Buu solution.

But, seeing as the spirit bomb itself wasn't an option, I had to improvise and settle for something else.

That something else was the Batman gambit to end all gambits.

I was either going to die a very horrific death here, by which point likely help save the universe in the long-term, or I was going to survive, and hopefully not kill off any chance of the good guys winning via empowering Aizen.

Worst-case scenario, I actually won and killed the beast and effectively indoctrinated Aizen into the Hall of Heroes, forever screwing any hope of the actual heroes winning the late game.

All in all, I probably had better odds with the shark that ate me and spat me out into this stupid world.

Sighing once, I promptly started covering my body in reiatsu, watching the still building massive AOE blast Moon-moon was cooking up.

At the last second, I sent a very worried, angry, and oddly enough, curious Aizen a single message through our shared link.

One that had him likely suffer an aneurism out of sheer stupidity, even as he begrudgingly agreed to help.

Though I doubt he had any other choice.

On a side note, I wondered if Nel could swallow something that big and just fire it back- Though the AOE part would probably still be an issue in hindsight.

Needless to say, the moment Moon- I shook my head.

He, quite frankly, didn't even deserve that blessed nickname.

The moment Josh Groban fired the attack upwards, I watched as the black walls of Kurohitsgui promptly returned and covered him completely along with his own attack.

The nearly indomitable shield box, unlike the previous uses, was shattered through like it was butter. The AOE attack, lashing out in a chaotic mess at the last minute interruption, though still covering my body in burns and pain, unlike anything I've ever witnessed. My bones practically felt like they were starting to melt at the sheer heat behind the attack.

Though at the very least, thanks to the fact its original intended target of damage had been, for lack of a better term, scattered as opposed to fully concentrated at my own location-

I was still, overall, breathing and somewhat alive.

Gritting my teeth once, I did the stupidest thing I could think of.

I rapidly started absorbing the scattered reiatsu, and converting it all around my blade. It's very hilt, let alone the steel itself, starting to melt at the contact.

With a final, forced, flash-step, a burning wall of effective magma at the tip of my hand, I sent off one final request to an utterly flabbergasted Aizen.

It took the staggering Primordial Hollow before me one moment too long to realize what was about to happen.

A moment that cost him everything.

With the chaotic reiatsu burning through my skin, I let off a savage grin to the creature, I used it as the primary source for the-

"Hado 96!" I ignored the sudden tremble and shudder of pain that coursed through my body, as well as the urge to grit my teeth. "Itto Kaso!" I swiped the blade upwards.

Needless to say, the attack that engulfed him, could be called anything but that as the burning reiatsu modified itself into a giant red-hot looking blade that carved its way through the hollow's body, separating the beast into two large pieces, straight down the middle of his body, as the blade of reiatsu itself continued on going further and further into the never-ending horizon, leaving a massive scar on the ground it touched, my hands practically started turning to ash in the process.

The steel blade itself had literally disappeared out of sight.

The middle of the Primordial Hollow's two broken and still burning sides was filled with very chaotic reiatsu, condensed down into a convulsing sphere of erratic energy.

Without a missed beat, I promptly stuck my disintegrating hand, more of a stump at this point, through it and pulled every last iota of reiatsu into myself.

The pain that followed, as well as the sudden intoxicating exuberance frankly, made the rest of what I'd gone through feel like a cakewalk.
