Urahara had just arrived on the battlefield.
Urahara: It's been a while, Aizen.
Aizen: Yes, around a hundred years.
Urahara: In the time I haven't seen you... You've taken up some interesting fashion.
Aizen: Everything in the process of evolving looks ugly.
Urahara: Who said anything about "ugly"? You fused yourself with the Hogyoku, haven't you?
Aizen: Not "fused." I'd rather you said "subjugated." The Hogyoku you could not control.
Urahara: You're right, I couldn't control it. At that time.
Aizen: "At that time"? That is some excuse you have. Though whether you're trying to make an excuse or not means nothing to me. Because...
Aizen stabbed Urahara before anyone could notice.
Aizen:You have already lost your chance to control the Hogyoku.
However, Urahara's body grew in size before popping, revealing that the person Aizen stabbed was just a portable Gigai.
Urahara: Rikujokoro!
The real Urahara appeared behind Aizen, binded him.
Aizen: Come to think of it, Yammy's battle records did list such an item. I let my guard down, figuring you'd never resort to such trickery. So, what do you plan to do now after tying me up with such a weak Bakudo?
Urahara: "Such a weak Bakudo"? Then let's see how many you can take.
Urahara then bombarded Aizen with Bakudo spells
Bakudo #63. Sajosabaku!
Bakudo #79. Kuyoshibari!
Urahara then started an incantation.
"Limit of the thousands hands, respectful hands, unable to touch the darkness. Shooting hands unable to reflect the blue sky. The road that basks in light, the wind that ignited the embers, time that gathers when both are together, there is no need to be hesitant, obey my orders. 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."
Aizen: Do you think I'd let you use such a Kido? I can easily break free of-
Urahara: Too late! Hadō #91. Senju Kōten Taihō.
The explosion was massive. (Y/N) and Ichigo looked at it in awe.
(Y/N): I've never seen Mr. Urahara go all out like this before.
Ichigo: Incredible...
Urahara: Aizen... It would appear you really did lower your guard when you embedded the Hogyoku.
Aizen: Exactly.
Aizen reappeared behind Urahara. Urahara tried to counterattack but was too slow to stop Aizen from landing an attack that cut into Urahara with his bare hands.
Aizen: Too slow. I did lower my guard. There is no longer any need to be on guard. I can feel it. Even when I was in the Soul Society, no one could compare to my powers. But now that I have subjugated the Hogyoku, my body has surpassed even that. There is no longer any need to dodge a Kido at the nineties level.
Urahara was still standing despite the vicious attack from Aizen.
Urahara: You've got it wrong. Not dodging my Kido isn't what I meant when I said you let your guard down. The old you would never have attempted to attack me twice without thinking.
At that moment, gold rings of energy surrounded Aizen's wrists.
Aizen: This is...
Urahara: It's a seal. I've sealed the outlets for Spiritual Pressure that are on the wrists of every Shinigami. You will be incinerated from the inside by your own Spiritual Pressure.
Aizen then exploded in a bright light.
(Y/N) and Ichigo were astonished. Isshin and (F/N) looked ahead unamused, knowing that Aizen wasn't dealt with yet.
Ichigo: Urahara!
(Y/N): That was amazing!
Urahara: It's not over yet.
Both: Huh?
Urahara: It would be child's play if that were all it took to finish him. We could laugh him off as a mere monster. He'll be coming out in no time.
Right on cue, Aizen walked out of the explosion, however his entire face was now covered, almost as if he was wearing a mask.
Ichigo: Wh-What the hell...is that?!
(Y/N): The Hogyoku needs better fashion...
Just then, Aizen took a step forward and somehow miraculously was in between the group. Everyone was caught off guard.
Aizen: You used a nineties-level Kido as a decoy to lure me into attacking, and you used a spell you developed to incinerate me from the inside. If I hadn't been your opponent... No, if it hadn't been me who subjugated the Hogyoku, the battle would probably have been over. But unfortunately, the Hogyoku you created exceeds your ability to understand it. Even this technique you created in anticipation of battling me, has no effect on me.
Urahara then drew his sword while approaching Aizen.
Aizen: Your spell didn't work, so now you're coming at me with your sword? As you wish.
(F/N) swiftly drew his pistol and shot a beam at Aizen forcing him to evade the attack, however, this put Aizen in the position (F/N) wanted. Urahara and Isshin were in the right spot to pinch Aizen as they both swung their swords at him. Aizen reflected both of their attacks, however, Urahara and Isshin's plan was a success as the moment Aizen made contact with them, they both restrained Aizen's arm and leg respectively.
Aizen: What nonsense is this? Do you really think...
Before Aizen could finish his sentence, another fighter entered the fray.
Aizen: Yoruichi?!
Yoruichi, who was now wearing a "unique" outfit, dropped directly down on Aizen, pummeling him into the ground.
Yoruichi: Well? Did that work?
Urahara warned Yoruichi hastily.
Urahara: Yoruichi, get out of the way!
Aizen burst through the ground, destroying one of the armor pieces that Yoruichi was wearing.
What's the matter? You're not done already, are you? You'd better make your next move quickly. I will crush them one at a time, down to your last remaining one. The number of methods you contrived to defeat me is proof of your effort and strength. At the same time, it represents the number of hopes you hold. If that is so, then what I must do is to crush each one of them. Now, come at me with your next attack.
Kisuke Urahara.
Yoruichi Shihoin.
(F/N) (L/N)
And...
Isshin Kurosaki.
(Y/N) and Ichigo were taken aback.
(Y/N): I don't know what we can really do here.
Ichigo: Are we going to lose?
(Y/N): Let's not lose hope yet... Dad and the other's sound like they still have more plans.
Urahara looked down at Yoruichi's broken leg armor.
Urahara: Well, this is a problem. That was specially made iron armor for use against Hierro. I didn't think it'd be destroyed so easily.
Yoruichi: Huh?
Urahara: What?
Yoruichi: You make it sound like it was my fault.
Urahara: No, I didn't mean it that way.
Yoruichi: Oh yes you did! You're trying to say it's my fault for letting my guard down! Aren't you?! Well listen up. You didn't put in enough effort when you made these!
(Y/N): I take offense to that! I help make those things too!
Yoruichi: No, your blueprints are fine (Y/N). Which means it's all Kiske's fault for being lazy during their construction!
Urahara: Okay, okay, I get it!
Aizen: I see. The fact that your leg still remains intact after being hit by me proves they are special.
Yoruichi: You mean my legs?
Yoruichi started showing off. Urahara decided to take a peak.
Yoruichi: What's with that look?!
Yoruichi hit Urahara in the nose.
Urahara: My nose hurts!
(F/N): I'm all for fun and games, but we're forgetting something, or rather, someone really important.
Aizen started to approach the group.
Aizen: There's no need to make a scene. It's meaningless to argue what is special. If a single swing makes one disappear, then three more swings will make that specialness disappear.
Urahara: Here he comes.
Yoruichi: I know.
Urahara: Are you good to go?
Yoruichi: Who do you think you're talking to? All I have to do is hit him with something other than my left leg.
(F/N): Try your best to create more openings for me. I need to weaken him down for us to take the advantage back.
Aizen then appeared in a blink of an eye, getting ready to attack the four adults. (Y/N) and Ichigo were still amazed at how the adults were keeping up with Aizen.
(End Song)
(Y/N): Talk about the difference in battle experience...
Pay attention. Your backs is wide open.
(Y/N) and Ichigo immediately were on their guard.
Gin: Psych! Just messing with you. How about we take a break for a second?
Gin took a seat on a piece of debris that was lying around.
Ichigo: W-What're you talking about?
Gin: Oh, come on. Let's watch the show.
(Y/N): You're pretty confident, aren't you? You think you've already won.
Gin: It's useless. I've been with Captain Aizen a long time, but I've never seen anything like this. Well, he fused with the Hogyoku without my knowing, so maybe that's to be expected. Don't you get it? There's nothing you can do. He's going to kill all of you. It's all over.
(Y/N): We're not letting that happen.
Gin: Yeah, that's what I thought you'd say.
Ichigo: And there's no telling what Aizen would do to you, now that he's like that!
Gin: Oh my, now I wasn't expecting you to say that. The way you said it... Sounds like you said it assuming you'd die. Maybe somewhere inside of you, you've already given up on this fight.
Ichigo: That's not...
Gin got up from the piece of rubble he was sitting on.
Gin: My, my... How pathetic. I was hoping you'd be better than that, but I guess you really are just a kid. You're weak inside. I couldn't possibly let Captain Aizen fight a coward like you. (Y/N), you've partnered up with a weakling.
(Y/N): I disagree.
Gin: Let's agree to disagree.
Gin took a stance. He took his blade and held it close to his chest.
(Y/N): Stay on guard, Ichigo.
Without any warning, a flash of light flew past Ichigo, who narrowly dodged it.
(Y/N): That was Gin's blade? It extended and contracted in the blink of an eye...
Gin: Kamishininoyari Butorenjin.
Just like last time, Gin's blade extended and retracted, however Gin did this in rapid succession, forcing (Y/N) and Ichigo to dodge out of the way. Ichigo for the first time in the fight, decided to use hollowfication to gain the speed necessary to dodge the attack, however his mask broke immediately after.
(Y/N): Yo, Ichigo, you doing alright?
Gin: How pathetic. Were you this weak? Even your mask is so fragile. Is that the best a Hollowfication could do? (Y/N) hasn't dropped hollowfication since this fight started. At least back then... You were more frightening.
Gin looked down at Ichigo.
Gin: Oh well. You, get out of here. This has now become a fight between Me and (Y/N).
