Hueco Mundo Pharmaceuticals. The company giant run by Sōsuke Aizen, head building located in Berlin, Germany. Legal guardian of Grimmjow Jaegerjaquez and Nelliel Tu Odelschwanck. A very important source of medicinals and healthcare throughout Europe, and even some parts of the world. However, unknown to the public was the secret gang organization, with Aizen as its leader, along with Gin Ichimaru and Kaname Tōsen as co-founders. Within it, eight elite members, dubbed the Espadas, sat at a long table situated within a special meeting room of their shared suite, Las Noches. Here, two young individuals had just been announced as new members of the Espada ranks.
"This is such bullshit! Who the hell made it possible for annoying brats to join our ranks?!"
"Yammy, I am sure you are aware that these two are not your average people. They were appointed by Lord Aizen, himself. These are his children." Ulquiorra was constantly keeping tabs on Yammy's behavior, and this exact moment was no exception.
"I get that, but this is ridiculous. Next thing you know, we're going to start taking in random ass hobos down the street."
"Yammy," Kaname added, "need I remind you of your position in the ranks? You are the weakest among us, and as such, you have been 'awarded' the title of Decimo. You should remember your place, and respect Lord Aizen's decisions and not question them."
"Oho! Insubordination. Better be careful, Yammy. Captain Aizen might very well show you direct punishment if you keep that up," chided Gin.
"Now now, let's continue with the meeting, shall we?" Aizen sighed. Turning his head, he beckoned for the two newcomers to enter the room. Grimmjow, now 13, and Nelliel, now 17, with hesitant steps, showed their faces. "Now, everyone, these two are my children, Grimmjow and Nelliel," Grimmjow lowly growled at that remark. "They have had ample training, and as such, will be, from this moment on, titled Sexta and Tercera, respectively. I am sure you will all give them a warm welcome," Aizen's eyes darted towards Yammy, which caused him to shift in his seat.
"Alright Aizen, we came like you asked. Can we go now?" asked Grimmjow, uninterestingly.
"Yes, you may go now." The two turned to leave when Aizen spoke again. "Oh, and Nel, I expect to see you in my office later. I have some things to discuss with you."
Nel started to shiver in both disgust and fear, with Grimmjow clasping a hand on her shoulder for comfort, as he dragged her out of the room with a snarl. Aizen watched the two leave with a small smirk.
"Alright, Nnoi. I need you to do something for me." Nnoitra glanced at Grimmjow with interest.
"What's up?"
"I'm planning on ditching this place - for good. I'm taking Nel with me. That bastard's done enough to her and I won't allow this to go on. He's fucking dead by the end of the night."
"Grimm, are you serious?! Do you have any idea what Aizen's capable of? You of all people should know, he's your guardian for God's sake!"
"I don't care! I'm fucking done. And you of all people should know how much I care about my sister. Which is why I'm even telling you, I know you two have feelings for each other, so I need you to help me out. I have a plan, but I can't pull it off without your help. Do you think you can help us escape from this hell hole?"
Shit. Grimmjow was serious. "...Okay. I'll help. You're lucky I like your ass. But what are you going to do about the testing? Aizen is close to completing the Hōgyoku. Even if you can kill him and escape, either Gin or Kaname will come after you two. And they will finish the Hōgyoku, which would put the whole world to shit, if you forgot."
"I'm completely aware of that. Which is another reason why I have to get out. I need to find someone that I met a while back. He can help me stop this shit with the Espadas. He can help me defeat the Hōgyoku."
"Who even is this kid you're talking about? This is probably the hundredth time you've even mentioned him, but you never say a name. Are you sure he can even be useful?"
"Oh, I'm sure. He'll help me out, even if I gotta force him to help. If not, we're all doomed." It got really quiet inside Nnoitra's room. The dread of them failing was falling on their shoulders. Even imagining how the world would turn out if they failed gave them chills.
After a while, Nnoitra asked, "So, you have a plan? Let me hear it." Grimmjow smirked.
"You scum! You said you had my back on this - what about our friendship? What about Nel?!"
Nnoitra grimaced, "Sorry, I lied. You got what you wanted, Aizen's dead. But I didn't say I wouldn't rat you out."
"Fucking bitch! I'll kill you!" With that, Grimmjow made his getaway with Nel before anyone else could find them. It was bad enough that four of the Espadas witnessed that argument. Nnoitra turned around and smirked at his comrades, leaving Grimmjow behind as a memory.
"That is how we became a part of the Espadas, and that is how we left. Grimmy was able to kill Aizen and free us. We were lucky," finished Nel.
Ichigo sat there, completely baffled at how utterly cruel the Espadas were described to be. Especially Aizen and Kaname. Gin just seemed to be a weird one, but Ichigo never let appearances fool him.
"Wow, that's freaking insane. And this...drug. I can see why it would destroy the world." He turned to look at Grimmjow, "We have to do whatever we can to stop them, the Espadas."
"Yeah, well, we're gonna need a plan. And it can't just be us three. We're gonna need help, and I honestly don't know who around can help us."
"It may not be exactly to your liking, but we can ask our friends to help us. Sure, they're all normal kids at a glance, but they have their own unique qualities that I think can help us out."
Thinking it through, and with no other choice, Grimmjow relented. "Fine, but I don't want anyone getting hurt. Especially them." Now, the fun part - explaining everything to their friends in a way that won't make Grimmjow, Nel, and Ichigo all look like mental cases.
