Bleach: Cero Devastador

It was like a flash, no, faster. But I can't be mistaken, his sword extended, graced my cheek and then retreated just as quickly and swiftly without making a sound. 

Let alone a 'whoosh', if it hadn't sliced my cheek off, I might have mistaken it for a housefly wandering around –a goddamn sharp housefly that is. 

"I understand now why you feel so sluggish, with that technique it is no wonder you don't need to move much. In fact, fights should be over in a heartbeat, don't they?~" I cleaned off the blood and regained my stance, now paying more attention to the position of that sword. 

Ichimaru Gin removed his mask and showed me the hideous visage of a jester with closed eyes. He's not a pussy, this guy has seen the street's true face, it was wonderful to fight someone like that. 

"You get it now, Inuzuri. Let's finish this quickly then!".

Once again he pointed his sword at me, but I wasn't that stupid. I used shunpo to flicker away from his reach.

*CLAANG!*

I parried the incoming sword, he had calculated the trajectory of my shunpo to catch me, and that alone was a ridiculous feat. 

"You're strong, Ichimaru!" I claimed.

Ichimaru smirked, "And to be able to parry this... you're a fucking beast!"

He came at me several times.

*CLAANG!*

*CLAANG!*

*CLAANG!*

I parried his sword all three times and kept skipping off his feet, trying to get closer. It doesn't matter what gun it is, the same principle stands... if I force you to close encounter hand-to-hand, the sword will be superior!

"Tch!"

He seemed irritated at his inability to reach me and began getting trickier, his sword extended so far that it almost reached the barrier each time while he made some distance between us.

*CLAANG!*

*CLAANG!*

*CLAANG!*

At some point our battle resembled two blurs shifting from place to place, slashing forth and leaving sparks behind, no silhouettes to be seen. The crowd clamoured while I tried to keep my calm. Sometimes I wasn't able to parry on time and his sword would grace me or slice my robes off. 

"How'd you manage to get such a swift Shunpo!?" He questioned me, but I didn't answer that question. 

"You caught me by surprise... but in the end, that's all there is. Guns are ultimately boring".

*WHOOSH!*

The more I flash-stepped close to him and switched my momentum, the more disorientated he was.

He 'shot' my afterimage, and by the time he realised it was an afterimage, I was already slicing my sword at his neck. His fighting style was rather lazy due to him not needing to engage too much in close combat due to this Shikai, which made him vulnerable to high speed. 

He managed to duck in time, but I still reached his shoulder, he flickered away leaving a trail of blood and holding his shoulder. 

"Gin-senpai!" The classmen shouted in disbelief. I delivered a heavy injury just like that. From now on, his performance would only weaken until he'd have to inevitably surrender. 

"Wh-What?!" Gin gasped, he looked behind me where all the ground was shattered and the barrier cracked, he didn't lack power... but he hadn't managed to land a single proper shot. 

If I hadn't learnt shunpo with Kurayami for these past few months, I'd be lying down on the floor pulverised like in my previous life; but I wouldn't fall to a gun again.

"Ever since I came to this place I have been wondering... what would I do if there happened to be a gun? So I have been preparing myself. Thankfully I did, otherwise, this fight would have been over very quickly" I smirked and then pointed at my head with a gun-shaped finger "You shouldn't have missed the first shot, Gin~".

He looked around like a lost cat, frowning and clenching his teeth. I didn't know what he was thinking but approached nonetheless, "Now I can exploit this weakness of yours, you should know how it is going to end..."

I pointed my sword at him, more specifically, his bleeding shoulder which would only get in the way. 

"Surrender or I'll slice your arm off".

*RUMBLE!*

An explosion of Reiatsu made me nearly blind. I had to cover my eyes at Gin who seemed to be releasing his whole power. Bankai, I was told by Kurayami that it was only achieved when a Shinigami reached the peak of compatibility with their Zampakutō and once achieved, that Zampakutō could never belong to anyone else... that Shinigami could also never have another Zampakutō except for that fateful one. 

Reaching Bankai was also a requirement to become a Captain of the Gotei13.

The current Gin, whose age was roughly the same as me, managed to achieve this stage.

The gossiping started around with even the five teachers who created the barrier struggling to maintain it and regenerate it from all the cracks Gin had created on it. 

"Impossible! Gin has achieved Bankai!?"

"That bastard kept that quiet".

"But he wouldn't be recommended to be Captain if he couldn't do this much, would he?".

"He may truly become an early captain at this stage".

"Kamishiro is a goner, he should give up now"

The balances decanted towards Gin after the display, the Reiatsu cleared out and his sword looked exactly the same, but his vibe didn't. 

"Ryōma..." Sakuya walked forward, she touched the barrier anxiously. Even from the outside, she could feel Gin's Reiatsu had at least tripled. The five teachers told her to back off but she didn't hear... they eased their scolding when Kurayami approached too to pat her shoulder. 

"You don't need to be anxious, trust him... Ryoma is prepared for this".

"I-Is he?".

"He has been preparing for the past few months to fight someone... and it's someone way above this Ichimaru's league" She said and subtly looked towards where the captains were located.

Among them, one of them (the one with spiky hair) could hardly hold his excitement. 

Gin gave a brief look towards the captains, 'I can't give away too much for him to see, but if I lose it will be troublesome too'.

...

"So this is a Bankai?" Ryoma said, uninterested. He didn't feel impressed that regardless of Shikai or Bankai, Gin's wakizashi looked the same. The difference in Reiatsu was clear, so he expected Gin to be able to pull out something. 

"You're unexpectedly calm amidst defeat" Gin commented with a hiss. 

"Have you defeated me already? How come I haven't noticed?" Kamishiro shrugged is shoulders at Gin's taunt.

It wasn't a taunt. 

"But, you are though~"

Ryōma looked down and saw the sword had already pierced his stomach, coming out the other end with massive amounts of blood dripping.

Everything with a speed that was imperceptible to the common eye. Even the captain gasped, none had seen the sword. 

*cough!*

"Ryoma!"
