The war was over. Aizen had fallen. However, he was the only casualty- his arrancar had all survived, taken as war prisoners by Soul Society. Their swords had been taken, their masks stripped, and the men and women who were Aizen's finest stood before Yamamoto, awaiting judgement.
"You all stand before me as criminals. However, in times of war, we all take actions we would not under normal circumstances. As such, it is not right to condemn you for simply following orders," Yamamoto began.
The Arrancar muttered amongst themselves. Yamamoto continued.
"It has also some to our attention that you are not normal hollows. We as Shinigami, must uphold our duty to exterminate hollows to protect the innocent souls they consume. But we hold no dominion over your kind, and as such have no right to pass judgement.
"However, you are still dangerous. And as our prisoners of war, we have right to decide what to do with you. We of the Gotei Thirteen have come to decide that it would not be just to merely execute you- nor can we let you go. And so we have some up with a solution that is neither.
"You all have a choice. Either accept banishment to Hueco Mundo, where you will no longer possess the ability to move between worlds to the Living Realm or Soul Society, or..."
There was a silence. The Arrancar watched Yamamoto with baited breath.
"Parole," he finished.
They looked amongst themselves.
"Parole?"
"Yes."
"...Could you maybe... Expand upon that?"
"Of course. This would entail living in Soul Society- within the Court Of Pure Souls, specifically, where you would be surrounded by Shinigami to ensure you do not step out of line. Your swords will not be returned to you, and should you cause harm to soul, your parole will be revoked and you will be banished to Hueco Mundo."
"And... And what? What do we do? Is this, like... Community service or something? Prison?"
"You do not have to do anything. You are allowed to simply exist as any soul does. Provided you follow our rules."
The Arrancar chattered amongst themselves.
"What if we don't like either of these?"
"Then you die. And your body will be donated to science. It's quite horrific."
More murmuring. One stepped foreward.
"Fuck you all. I'm the King of Hueco Mundo- send me home," Barragan bellowed.
"Very well," Yamamoto nodded. Barragan was immediately seized and thrown forcibly into the Gargantas a few yards away.
"And the rest of you?"
"Um. That parole sounds pretty good to me."
There was a general murmur of assent.
"Very well. We will assign you all to living quarters within Seireitei. For convenience, you'll all be living together in one house because it's easier to keep track of you that way, and if you don't like it, suck it up. That is all."
The Arrancar looked amongst themselves again.
"Guys... I just realised something," one of them said suddenly. "We don't have to wear Aizen's ugly white uniforms anymore!"
There was a breif silence.
"Dude, I'm totally getting a real pair of pants."
"Screw that- I"m not gonna wear ANY pants at ALL!"
"I"m gonna wear something yellow!"
"I'm gonna get blue!"
"I'm going to buy a bra!"
"That's great! You need a bra!"
"I know! I've wanted one for so long."
Amongst the chattering, Grimmjow Jeaggerjaques picked at his ear.
"Well. All's well that ends well."
