You know.

(Y/N) and the crew were really having the time of their lives right now. They were making their way back to their hiding spot so that they could prepare a way back home.

However...

Isane: Attention all Thirteen Court Guard Squads captains, lieutenants, and seated officers. And also the Ryoka. This is Squad Lieutenant, Isane Kotetsu. This is an emergency announcement from Squad Captain Retsu Unohana and I, Isane Kotetsu. Everything I am about to tell you is the truth!

Isane used a Kido spell to perform a mass communication system to everyone in the Seireitei and explain the current situation. From what (Y/N) could gather from the announcement, one of the Captains that were killed, faked his death, and tried to put the captains against each other in some conspiracy theory. What surprised (Y/N) was the fact that Isane and Unohana found it necessary to contact (Y/N) and his friends about it. They had nothing to do with their affairs. But then (Y/N) had a thought. A terrifying one.

Either they believed this Captain wanted them dead.

Or he wanted Rukia dead.

(Y/N): Guys, we need to turn back. Now!

(Timeskip) Renji Pov

Renji was close to the exit of Seireitei, however he was teleported right back to the execution site. He was met face to face with Captain Aizen of the 5th Division. Renji fought with all of his might to protect Rukia, however Captain Aizen was on a whole other level.

Aizen: Between you, Izuru and Momo, you really are the most troublesome of the three, Abarai. I knew that I could use you three when I first met you. So when you three joined the Thirteen Court Guard Squads, I had you all assigned to Squad right away. Then I made the two who were more useful. I sent you away because you seemed troublesome. It seems my instincts were right. This is the last warning.

Leave Rukia Kuchiki here and back away.

Renji: I refuse.

Rukia: Renji!

Renji: I won't let you go Like I'd ever let you go

Rukia: You idiot.

Aizen: I see. Too bad.

Aizen went for the killing blow

However...



Ichigo: Hey. What's wrong, crouching down like that? It looks like Rukia is too heavy for you.

Ichigo blocked Aizen's strike, while (Y/N) prevented Gin from intervening Ichigo's rescue attempt. Another captain, Tosen, was (watching? Idk he's blind) spectating in a few steps back, not speaking a word.

Ichigo: We came to give you a hand, Renji!

Gin: Sorry. I didn't think the boy would have backup.

Aizen: No matter. It's fine. There is no difference whether there is one piece of dust to brush off, or two.

(Y/N)'s POV

Gin: Well then, what will you do now, (Y/N)?

(Y/N): Take a step forward and I'll deal with you.

Gin: Will you now?

Gin intentionally took a step forward and (Y/N) wasted no time delivering a swift strike with his scythe. Gin dodge gracefully before delivering a palm strike to (Y/N)'s stomach.

Gin: Let's not get hasty now. After all, you're Bankai as it is now, cannot touch me, let alone Captain Aizen.

(Y/N) got up, wiping off the blood leaving his lips.

(Y/N): Sorry but I can't allow you to-

Gin: Interfere with Ichigo's fight. To be honest I don't need to. Aizen seems to be handling both him and Abarai easily.

(Y/N): What?

(Y/N) turned around and saw Ichigo and Renji getting absolutely demolished. (Y/N) turned around to help both of his allies out before getting ambushed by Gin.

Gin: What do you think you're doing? Turning your back on the enemy after starting a fight.

Shoot to kill, Shinso.

Gin activated his shikai and immediately pierced (Y/N). Gin extended his blade long enough that it threw (Y/N) off the cliff they were standing on. Gin didn't bother chasing after (Y/N).

Gin: Aw... I thought you'd have put up a better fight than that.

Gin looked over in Aizen's direction and saw Ichigo and Renji down for the count. Aizen made his way over to Rukia. But before he could touch Rukia, Aizen heard something in the distance. Almost an incantation of some sort.

Light bullets, eight bodies, nine items, book of heaven, diseased treasure, great wheel, grey fortress tower. Aim far away, scatter brightly and cleanly when fired."

Hadō #91. Senju Kōten Taihō

In the distance, (Y/N) who made his way back up the mountain as swiftly as possible was just finishing the incantation of his strongest Hado spell. This was (Y/N) last ditch effort as he was running low on spiritual energy to keep up his Bankai.

(Y/N) launched his attack at Aizen, however Aizen simply summoned a barrier to block his Kido technique.

Aizen: Ah, I've heard of you. (Y/N) (L/N). The one that can summon Hollows. You may be of use to me.

(Y/N): Huh? Why would I ever cooperate with you?

Aizen: Oh, I know quite well that you'll never agree to it. But unfortunately at this moment you are in the way.

Aizen casted a kido spell, and in an instant, an black coffin with spears protruding out of it surrounded (Y/N). (Y/N) tried to absorb the energy of the kido spell to weaken it enough to break out. However it was too late.

Aizen: Hadō #90. Kurohitsugi



The spears stuck in the black coffin dug further into the box, stabbing into (Y/N). Once the coffin disappeared. (Y/N) laid in a puddle of his own blood, barely holding on to consciousness.

(Y/N): *thinking* Damnit, just when I thought I was strong enough to take on the captains, I'm just shown time and time again I'm still weak.

You're not weak, just let me take care of him. I am you after all.

Huh? It's that voice again.

I am not just "that voice" I'm you! Don't you remember what I said last time? If you die, I die. And so the next time something like this came up, I'd take over. Whether you like it or not.

I don't know who you are, thinking you can just waltz in here and take control of things but I won't-

This isn't up for discussion.

Aizen: Gin, Tosen, please secure (Y/N)'s body. I'll be taking him with us.

Gin: Of course.

Tosen simply nodded

As Gin walked towards (Y/N)'s body, (Y/N)'s hand gripped onto Gin's arm. Gin looked at (Y/N)'s face and saw half of a Hollow's mask growing on top of his face.

https://youtu.be/Ol5FOedxSrY

(Y/N)?: Don't think for a second I'm letting you three out of here without a couple of broken bones. And that's if I'm gracious enough to not take your lives.

(Y/N) Got off his feet, all while still holding onto his arm. The wounds that he got from Aizen earlier were healing as he was getting up.

(Y/N) used his free hand to hit Gin in the head with a palm strike, before grabbing him by the face and lifting him up, slamming him into the ground. (Y/N) stepped on Gin's chest before charging up for a punch, aimed for Gin's head. Gin barely blocked the punch, however (Y/N) opened the palm of his hand and a Cero was in his hand. (Y/N) fired the Cero point blank in Gin's face, leaving a giant crater.



(Y/N) turned his attention to Tosen, who was trying to hit (Y/N) with a sneak attack, but it didn't work. (Y/N) dodge the attack by Flash Stepping. (Y/N) was moving so fast that he left multiple after images similar to Soi-Fon during their fight.

Just then (Y/N) landed a multitude of attacks and the after images almost mimicked the actions of (Y/N). The sheer destructive punches that were delivered were able to knock out Tosen.



(Y/N) turned his attention to Aizen with a sadistic grin on his face.

(Y/N): Was this power what you were so interested in?

Aizen: As a matter of fact, yes. It was quite the demonstration. However-

(Y/N) flashed out of sight and grabbed Aizen by the throat, charging a Cero with the other hand. (Y/N) then slammed the Cero into Aizen's stomach, causing a massive explosion.



(Y/N) then started to laugh sadistically. Ichigo, Renji and Rukia looked out in horror at the sight.

Ichigo: Is that really (Y/N)? Was I like that during my fight with Byakuya?

Renji: He's a wildcard, that's for sure. As long as he doesn't attack any of us we should be safe.

(Y/N): Now, where did that slippery bastard go?

Aizen: As I was saying. You should have more control.

(Y/N): Huh?

Aizen then chopped (Y/N) in the back of the neck. The black hooded robe that (Y/N) wore reverted back to being a standard Kimono, as (Y/N) was no longer in Bankai form. The broken Hollow Mask fell off of (Y/N)'s face as he went unconscious.

The situation was grim to say the least. After (Y/N)'s display of power, One of the captains, Komamura, showed up to fight Aizen and lost in an instant once Aizen casted Hadō #90. Kurohitsugi.

Aizen walked up to Rukia and stabbed his hand through her chest and pulled out something that nobody knew the name of. Right before Aizen could kill Rukia, Rukia's brother, Byakuya came in to save her. At the same time Yoruichi and Soi-Fon appeared out of thin air, restraining Aizen.



Soon enough every single captain of the Court Guard Squad showed up to corner Aizen and his two unconscious subordinates.

Yoruichi: Sorry Aizen, but you're surrounded. It's over.

The only thing Aizen did was laugh.

Yoruichi: What's so funny?

Aizen: Oh I'm sorry... It's time.

Yoruichi looked up in the sky and knew right away that something was wrong.

Yoruichi: Soi-Fon, get back!

Both of them jumped back as a beam of light shined down on Aizen and his two unconscious subordinates. In the sky was A Huge Menos Grande tearing the sky open.



Ukitake: Have you fallen so much, Aizen?

Aizen: You're too arrogant, Ukitake. No one stood at the top from the beginning. Neither you, nor me, nor the gods. But that unbearable vacancy of heaven throne ends now. From now on, I will stand atop the heavens. Goodbye, Shinigami. And goodbye, Ichigo. (Y/N). For humans, you two were quite amusing.

???: Like hell you're escaping!

The voice came from (Y/N). He pushed his Spiritual energy to the max to summon a Menos Grande of his own. The skies behind him tore open and A Menos crawled out ready to shoot a Cero at Aizen as he ascended in the sky.

(Y/N): It's clear as day, letting you get away isn't going to be good for us in the future.

Aizen: Don't worry (Y/N), I'll come back for you soon enough.

(Y/N): FIRE

But before the Menos Grande could fire the Cero, it suddenly stopped before vanishing almost instantly.

(Y/N): I failed...

(Y/N) push his body past it's limits, not being able to successfully conjure a Menos Grande to fire a cero. (Y/N) fainted once again, pushing his body past its limits. He cursed himself for not being able to stop Aizen. But then again, not even the Captains had what it took.

Was Aizen just that much stronger than everyone?

(Y/N) didn't know.

He just needed time to rest.

To be continued

I couldn't wait to write Hollow (Y/N). I imagine he fought vastly different since he doesn't let himself be held back by morals like the original would. His goal is to simply survive. I won't reveal what (Y/N)'s Hollow mask looks like quite yet. For now you can envision it however you like.
