Sado and Ishida started running while Ishida pulled on Ichigo. I felt no need to run but I wanted the story to progress so I followed as well. The big ass guy we were running from was more like a janitor compared to the other Arrancar. I felt more embarrassed running away then killing him on the spot but I knew that fighting in an underground location was a bad idea not to mention that we don't know where we are yet. We hurried along as Ichigo protested to fight it out instead. We explained that we are in some underground location and it is ill advised to start any fighting.
Ishida: In any event, it'd be unwise to fight here until we come to a wider place.
Sado: We're coming out Ishida! What a big room.
Ichigo: Alright! No complaints here, right Ishida?
Ishida: Stairs! They might connect to the outside! I'll go check!
The moment Ishida started running towards the stairs another Arrancar stepped out. This one was smaller than the one we ran into in the corridors.
???: Where are you going intruders?
The big one we ran from caught up and now we were in between them. Can't go forward nor backward. I just sighed because the power they were giving was far too weak for me to step in. I nodded to Sado for him to take care of them with Ishida.
Sado: I'll take them on.
Ishida: Kurosaki, step back.
Ichigo: I wasn't going to say anything.
Ichigo learned quickly how powerful Sado has become and felt relieved that the burden he supposedly carried grew lighter with Sado's strength. Ishida explained that the closer the Arrancar looked human the more powerful they were and the more they looked like regular Hollow the weaker they are. The little one named Iceringer took offence to that.
Iceringer: Not just Demora, but you're saying that even I, Iceringer, have a "lower power of reasoning"? I could never overlook such a comment.
Demora: IIICCCCCEEEEEE!!! You bastard, dun talk like I'mma only dummy!!
Sage: You can't blame us, you sound like a dumbass too.
Like their sizes indicate the smaller one, Iceringer, was faster and the big one, Demora, was stronger. It made no difference they were going to die all the same. Ishida only trained with his father so he did improve but not as much as Ichigo or Sado. Ishida chose to fight the big guy who approached him first. Sado went along with Iceringer but made quick work of him. Sado didn't even use any type of armor, he just flashed in front of Iceringer and blasted him away, splattering him on the wall.
Sage: Hey Ishida, Sado's done, do you need help?
Ishida: No I got this!
Sage: Being stubborn will get you nowhere. Your arrows clearly can't inflict damage without you expending a sizeable amount of power, just let Sado handle it. We are pressed for time as it is.
Ishida: Fine.
Sado again didn't use any armor and blasted Demora away. Ishida didn't know how to feel from the expression on his face. Within a short time period, Sado had vastly surpassed him in strength and speed. With that out of the way we took the stairs and found ourselves in a desert with white sand.
Ichigo: This is Hueco Mundo? How do I put this, it's a lonely place, theres nothing here and its pure white.
Sado: There's plants but they are withered.
Ishida: No. They're made of a quartz-like substance.
When we turned to see the building we were under even I was taken aback by the sheer size. I knew that the scale was enormous but to see it up close is a different matter all together. I was not disappointed on the scenery but the fighting left much to be desired. While the others ran I floated after them for what seemed to be hours until a burst of sand from the ground exploded to reveal a giant worm like Hollow and other Hollow chasing someone. That someone looked like a human child so when Ichigo saw this he ran in to help the child.
Ishida: A…a human!? It can't be, humans other than us!? There's no way!
Ichigo: We'll think about it later! Let's save them!!
Ichigo, Ishida and Sado ran in to hit the little Hollows and the giant worm away from the child. I knew who they were so I did nothing.
Child: What did we do to you guys!? Quit bullying us!
Ichigo: A mask! Are you a Hollow?
Group of Hollows: We are reeeaaally sorry!
Child: We never thought that this endless chase play would create such a misunderstanding. It's no fun here in Hueco Mundo!
Ichigo: Play? You were crying.
Child: Yes! I'm an extreme masochist so it's not fun unless they chase me till I cry a little.
Ichigo punched the big headed Hollow. I couldn't contain my laughter.
Ichigo: What are you teaching this kid?!
Big Headed Hollow: Nel, help!
Ishida: Nel? Is that your name?
Nel: Yes! I am Nel Tu, the Arrancar!
Pesche: I'm Pesche, Nel's big brother.
Dondochakka: And I'm his big brother, Dondochakka.
All 3: And the big one behind us is our pet, Bawabawa!
After the whole schitck with them being siblings and Ichigo being a Shingami passed, we continued to "Las Noches" ("The Nights" in Spanish). We encountered a giant Hollow composed of sand called Runuganga. As powerful as Ichigo and Sado may have become they can't deal with enemies that required a certain element to defeat. That's when we met up with Rukia and Renji because Runuganga was frozen solid and destroyed.
Right after the sand Hollow was destroyed Ichigo went to greet Rukia and Renji but instead was met with punches to the face by both of them. They had their small little confrontation about why we left without them but they soon made up. We continued forward and finally reached Las Noches. We parted ways from the Nel's group but I knew that they would follow Ichigo and his group. When we entered the giant building, there was a split in the path with many corridors.
Once we split up I chose to take a stroll in the path that I chose. I wasn't worried about the others if the story didn't deviate too much. By the law of cause and effect, I was hoping that Aizen wouldn't disappoint me because the corridor I was following had stronger waves of energy being emitted. Far stronger than that of Ulquiorra. The entire time I was trying to sense some type of energy signature coming from this place but the entirety of Hueco Mundo was made of Spirit Particles so the energy fluctuated and I couldn't get a proper read. Now that we entered the building I felt the Reiatsu clearly and Aizen didn't disappoint. I was reading 5 distinct energy signatures, since the only one close to number one was Ulquiorra I could only compare them to him. I was getting giddy as I could finally use my Bankai without giving a shit about the area. I licked my lips in anticipation as I restrained my aura but let out my blood thirst. Every step I took in those hallways cracked the floor, so I sped up my pace.
Sage: (I yelled out, loud enough to be heard everywhere) DON'T YOU DARE DISAPPOINT ME, AIZEN!!!!!
