The four boys tracked through the endless white desert for who knows how long and it felt like they weren't making progress in making it to the palace.
At some point, the 4 boys collapse on the ground in exhaustion.
Ichigo: If the palace looks like that from this distance,then in contrast, doesn't that mean that the palace and everything else is terrifyingly huge? I-It's not actually a mirage or something, is it? *panting*
(Y/N): *panting* I doubt it
Uryu: We can't see mirages here. To make things easier,should I explain how mirages work?
Ichigo: You don't need to!
Ichigo looked to his side and saw a hollow, in the shape of a lizard. It took notice of Ichigo and it dug itself underground.
Ichigo: When I came here, I thought this was a world of death with nothing in it. But surprisingly there are small animals. They're Hollows, though.
(Y/N): Now that you say it, it makes me wonder... Was that Hollow originally a normal animal? The closest we've gotten was Yuichi. But then again, he was a human soul possessing a parakeet.
Ichigo: I don't know. Sounds complicated. Though I wonder, Don't Hollows mainly eat human souls? I wonder what these little guys survive on here.
Uryu: Here in Hueco Mundo, the reishi density in the air is pretty thick. The smaller Hollows probably get the nutrition they need just by breathing.
Ichigo: The reishi density in the air?! You can tell that?!
Uryu: The Quincies are a tribe that fights by using the reishi around them. We function better when the reishi is denser! I confirmed it in my last battle. If I can get a knack for it, I should be able to display my powers better here than in the World of the Living or in Soul Society.
As Uryu explained, the cogs in (Y/N)'s brain started turning. As (Y/N) was thinking, Uryu and Ichigo continued their bickering.
Ichigo: Oh? That's pretty convenient. You function better when there's more reishi. You're like a Hollow!
Uryu: What?! Shinigamis are like that, too!
Ichigo: Huh? I'm different!
Uryu: Just you? Kuchiki recovered her spiritual power in Soul Society!
Ichigo: Maybe there's something wrong with Rukia!
Uryu: I don't know how many Hollows Aizen has turned into Arrancars or how many he controls. But even if he doesn't control them, we're still enemies as well as food for the Arrancars. The reishi is dense here in Hueco Mundo, so even if we see an ordinary-looking Hollow, we should assume that it's much stronger than it looks. We must observe them carefully...
Ichigo: You've been talking too long! Seriously, you may be a smarty-pants but you talk in paragraphs! Keep it short and easy to understand like (Y/N)!
...
...
(Y/N)?
(Y/N): Huh?
(Y/N) was snapped out of his thoughts as Ichigo called out to him.
(Y/N): Oh, sorry... What were you guys talking about?
Ichigo: Dude, you were spacing out. What's going on?
(Y/N): Well, Uryu brought up something interesting. "Here in Hueco Mundo,the reishi density in the air is pretty thick."
Ichigo: Okay... And...
(Y/N): If Uryu can use the reishi in the atmosphere, then so can I! The other three boys were shocked at the idea.
Uryu: Wait, are you implying you can use your reishi absorption indefinitely while in Hueco Mundo?
(Y/N): That very well might be the case. And here I was, thinking of a loophole to use hollowfication and arrancar summons. And here comes Hueco Mundo, giving me an answer.
Ichigo: Take notes, Uryu. That was a simple explanation.
Uryu: H-Hey, I was the one who explain the situation to you-
The conversation was interrupted by a Hollow in the shape of a sandworm and 2 other weird looking hollows chasing what seems like a little girl.
Ichigo: A human?! Could it be that there are other humans aside from us?!
Uryu: That can't be!
Ichigo: Think about that later! Let's go save her!
Everyone jumped into action. Ichigo was the first one to swing his sword at one of the hollows. Uryu then cut off the smaller hollow, holding him up with his arrow. Chad held the sandworm, preventing it from approaching. (Y/N) just sat between the hollows and the little girl as a last line of defense if one of them slipped pass.
However, it seemed the group jumped the gun.
Arrancar 1: It hurts! It hurts!The tip! The tip is poking me!
Little girl: Stop! Stop that!What did we do to you?! Stop picking on us!
Ichigo: A mask?! You're a Hollow?!
The four hollows (including the sandworm somehow) bowed.
The three hollows : We're really sorry!
Little Girl: We never thought that our game of eternal pursuit would cause such a misunderstanding.
Uryu: Game of eternal pursuit?
Little Girl: Unfortunately, Hueco Mundo doesn't have any entertainment.
Ichigo: A game? You were crying a little.
Little Girl: Yes! Nel is a real masochist. It's no fun unless Nel is chased to the point where Nel cries a little!
(Y/N) and Ichigo immediately scolded the two other arrancars capable of speech (the sandworm could not speak).
Both: What kind of words are you teaching this kid?!
Ichigo: Is Nel your name?
Nel: Yes! Nel is an Arrancar named Nel Tu.
(Y/N): An Arrancar?!
Nel: Yes! By the way, this is Nel's older brother-
Pesche: Pesche.
Dondochakka: And the oldest brother, Dondochakka!
Chad: Huh?
Nel: And the big thing behind us is our pet Bawabawa!
Nel gestured to the sandworm.
Ichigo: Wait, wait, wait, wait!
Nel: What is it?
Ichigo: Arrancars have siblings and pets?!
(Y/N) then came to the realization. He never actually told his best friend that his mom was actually an arrancar.
(Y/N): I-I'm sure they can-
Nel: How rude! Of course they do!
Dondochakka: I ran into her by chance and she was so cute that I became her brother.
Pesche: Oh, same here!
Ichigo: That's not what you would call siblings.
(Y/N): Don't do that to them Ichigo!
Dondochakka: Then...Then what are we?!
The 4 arrancars looked down in despair. (Y/N) gave Ichigo a look of a disappointed parent.
Ichigo: I was wrong. You guys can be siblings.
(Timeskip)
The group was now riding on top of Bawabawa. Ichigo decided to bring up something that was on his mind as they were making their way to Las Noches.
Ichigo: Are you guys really Arrancars?
Nel: What are you saying?! Can't you see this splendidly cracked mask!
Ichigo: It's just that. You seem different from the guys that came to the World of the Living.
(Y/N): I doubt every arrancar is under Aizen's command.
Nel: Oh! Of course! The ones who went to the World of the Living are Numeros!
Ichigo: Nume- what?
Nel: Numeros are those who are greater than Menos Grande and have become Arrancars! They go by two digit numbers and are allowed to directly serve the Espada! That's great, isn't it? I'm jealous. The Numeros are the fighting experts! They're completely different from trash pests like us!
(Y/N): "Trash pests"?
Nel: That aside, you look even less like an Arrancar! You don't have any mask and you two wear a black kimono. It's as if you're a Shinigami.
...
...
Nel: What's...umm...your occupation?
Ichigo: Ichigo Kurosaki, Substitute Shinigami!
(Y/N): (Y/N) (L/N), Substitute Shinigami.
Uryu: Quincy, Uryu Ishida.
Chad: Yasutora Sado, I'm human.
Nel: Two Shinigamis?! A Quincy?! A human?! Put all three of them together and they're-
All three arrancars: Bad guys!
Nel: They're going to kill us!
Pesche and Dondochakka: Yeah, Yeah!
(Y/N): No. We're not going to kill you.
Ichigo: Honestly. This is throwing me off. Arrancars like this exist, huh? What should we do?!
Before anyone could answer, the group was ambushed by a sand golem who rose from the ground.
(Y/N): Who is he?!
Nel: It's Runuganga, the Guardian of the White Sand!
Runuganga: I was just informed only moments ago by Las Noches that we had intruders. I never would have thought that those intruders were associated with trash pests like you. Unforgivable! I'm going to turn you all into desert sand!
Nel: No It's not like that! We actually-
Ichigo: Stand aside.
Nel: Huh?
Ichigo: It seems we can't play around with him. Let's go, monster!
Ichigo charged up a Getsuga Tensho, and sent it towards the guardian, however it did no damage as the hollow just regenerated from the attack. In retaliation, Runuganga created a pit of quicksand to drown the group.
(Y/N) grabbed Pesche and Dondochakka and flew out of the quicksand while simultaneously summoning Panzer to lift Bawabawa out of the sandpit. Ichigo grabbed Nel and Chad grabbed Uryu.
As the group made it out of the sand pit, they turned around to see Runuganga was frozen from head to... sand I guess?
(Y/N): Who in the world?
(Y/N) and the rest of the group turned around and saw Rukia and Renji standing side by side.
(Y/N): I like our odds in this rescue mission now.
