After the intense conversation and revelation with Tatsuki, (Y/N) left school and made his way directly to Urahara Shop. On his way there, Calavera poked her head out of (Y/N)'s backpack.
Calavera: You sure that it was a smart idea to tell her all of that? She may try something reckless.
(Y/N): Unless she miraculously unlock Fullbring abilities or somehow sneaks into whatever method we use to get into Hueco Mundo, which both situations are highly unlikely, I doubt Tatsuki will be able to do anything.
Calavera: But not impossible.
(Y/N): True. But the fact of the matter is, the situation needed for something like that to happen either needs to be intentional. The percentage of Tatsuki getting any supernatural ability is slim if it happens by coincidence. And even if she did get any kind of power, it would be too new to go around fighting arrancars with.
Calavera: You really want to keep her out of this fight huh?
(Y/N): Of course. If the situation wasn't a supernatural one, I'd allow her to help no questions asked. But the truth of the matter is that I wouldn't be a good person or friend to let someone completely defenseless enter a fight with beings of mass destruction. That's like sending a baby out to war. I only told her the truth to ease her worries.
Calavera: That's understandable.
As (Y/N) and Calavera were wrapping up their conversation, they reached the front of Urahara Shop. Upon entering, (Y/N) saw Chad talking to Urahara.
(Y/N): Chad?
Chad: (Y/N), you're here.
(Y/N): What are you doing here?
Chad: I was here for training.
(Y/N): So that's why Urahara told me, Yoruichi, and Soi-Fon that the Training Ground was reserved last month...
Chad: You and Ichigo are going to save Orihime right? Let me join.
(Y/N): Of course! We could use your strength out there! Speaking of, Mr. Urahara!
Urahara: Hm? What is it, (Y/N)?
(Y/N): Can I ask for permission to take Ururu and Jinta with me to Hueco Mundo. If they're alright with it, of course. We need all the help we can get!
Urahara: Sorry, (Y/N). No can do. I still need Ururu and Jinta here. I'll need their help getting some last minute preparations ready for the fight against the arrancars.
(Y/N): What about Yoruichi?
Urahara: She's in the same boat.
(Y/N): I see, a shame... It'll be hard to save Orihime with just Me, Ichigo and Chad.
???: Then what about me?
(Y/N) heard a familiar voice he hadn't heard in a month. He turned around and saw Uryu, in his Quincy attire.
(Y/N): Uryu? You're here? I thought you-
Uryu: Lost my abilities? I did... but I got them back. And they're stronger than before.
(Y/N): That's great! So we have a group of four. Although we're pushing it a little with only four members, it's the best we can do for now.
Chad: Speaking of, where's Ichigo?
(Y/N): I'm sure he'll be here soon. He got caught up at school. Give him some time.
(Y/N) then turned towards Urahara.
(Y/N): Mr. Urahara, do you know how we can get to Hueco Mundo? I have an idea of my own but I thought it would be better to know if you found anything? You always seem to be a step ahead of everyone else.
Urahara: I'm glad you asked.
Urahara gestured towards some weird contraption that he made.
Urahara: With this, I'll be able to create a portal that will lead straight to Hueco Mundo. Though, I am curious... What did you have in mind, (Y/N).
(Y/N): It was just a theory, but I assume most hollows know how to create a gateway to Hueco Mundo as a way to travel between worlds. I think my hollows can create a gateway for us straight there. But I haven't tried it myself.
Urahara: Then let's try it...
(Y/N) nodded before summoning a normal hollow. (Y/N) tried his best to recreate a Garganta. After a few failed attempts, (Y/N) was able to create a small ripple, reminiscent of the portal that the rest of the arrancars used to travel to the world of the living. However, (Y/N) couldn't keep it open nor make it big enough to be used.
(Y/N): Phew... This is much harder than I thought...
Urahara: Well this is the first time you've tried to use a spell that was created to travel between worlds. The amount of spiritual energy needed to connect to both worlds is vast. Now save your energy, you'll need it once you get into Hueco Mundo.
(Y/N): Right.
(Timeskip)
After a few hours, Ichigo made his way to the training grounds under Urahara Shop. As Ichigo made his way down, he was surprised to see Chad and Uryu.
Ichigo: Huh? Chad? Uryu? What are you guys doing here?
(Y/N): Have you already forgotten? We need a team.
Ichigo: But... Uryu your-
Uryu: Please don't make me repeat myself... I have my abilities again. No need to worry.
Chad: Ichigo, don't be afraid to ask us for help. We're strong enough.
(Y/N): We can't do this alone, Ichigo. We need them. Besides, they'd follow behind even if we didn't take them.
Ichigo: ...
Ichigo let the words of his friends sink in for a bit. Ichigo's face of indifference turned into one of hope.
Ichigo: .. Right! I'm sorry for not believing in you Chad. Uryu. We can do this!
Urahara: It seems like you're finally prepared. Are you ready? There are terrifying Hollows waiting for you in Hueco Mundo! Brace yourself!
All: Of course!
Urahara: Alright then...
Urahara started an incantation of a spell of some kind, while standing on his contraption. Just then, a huge tear in the sky opened up that looked exactly like a Garganta.
Urahara: If you move towards the darkness,you should reach Hueco Mundo.
Ichigo: All right. Mr. Urahara... Can you take care of everyone at home for me? I want you to tell them not to worry about me.
Urahara: All right... What about your friends?
Ichigo: I'll apologize to them when I get back.
Urahara: All right. What about you (Y/N)?
(Y/N): Calavera will be able to explain everything to my family. However, I'm with Ichigo on this one. I'll apologize to my friends for my long absences.
Urahara: I swear, you two... Well, go give it your best! Be careful.
Ichigo: Yeah... Let's go!
The four boys dived into the Garganta, making their way into Hueco Mundo. The moment the coast was clear, Urahara shouted.
Urahara: Why don't you come out now?
Just then, Mizuiro, Keigo and Tatsuki came out of their hiding spots.
Keigo was the first to talk.
Keigo: Umm... When did you notice us?
Urahara: Since before you came here. I knew that you were following Kurosaki,so I left the store unlocked. My, my... Kurosaki has been naive,as usual. He thinks that he's cut his ties just by being a little cold. Now then... I guess I should do my job.
Tatsuki: W-Wait a minute!
Urahara: Hm?
Tatsuki: (Y-(Y/N) told me about Shinigami and Hollow stuff. It's pretty hard to understand but... is it really true?
Urahara: ...Yes. Yes it is...
Tatsuki: So they really are putting their lives on the line to save Orihime...
Mizuiro: You didn't really tell us what (Y/N) told you on the rooftop. It seemed really serious.
Keigo: So (Y/N) didn't confess to you?
Mizuiro: Keigo, this is not the time.
Keigo: Sorry... just wanted to lighten the mood.
Urahara: I guess I have time to give a simple rundown...
(Meanwhile)
The group of 4 were running through the gateway to Hueco Mundo. The 4 had to create a footing of spiritual energy to make their way to Hueco Mundo.
(Y/N): Beyond this point is Hueco Mundo?
(Y/N) and Uryu had an easy time making a footing, however, Ichigo and Chad weren't having the greatest time.
Ichigo: Crap! He talked about making footing with reishi as if it was easy! I'm really terrible at little things like this! Are you all right, Chad?!
Chad: Not a problem.
Ichigo: Sorry!
Uryu: My, my... That's pathetic... Can't you make your footing a little better?
Ichigo: Shut up! I told you I'm not good at things like this! Anyway, what is that thing you have?! You're cheating, aren't you?!
Uryu: It's a variation of the Hirenkyaku...This is nothing.
Ichigo: Make one for me, too!
Uryu: Sorry... Your inability to control Spiritual Pressure Means that you couldn't use this.
Ichigo: What? You talk as if I don't have any powers!
Uryu: Am I wrong? You can't even make your own footing properly.
Ichigo: I'm going to kill you!
Uryu: I'll go on ahead of you.
While Ichigo and Uryu were bickering, Chad decided to speak up about something on his mind.
Chad: Ishida... I heard from Mr. Urahara that you made an agreement with your father. In exchange for his training, you wouldn't involve yourself with Shinigamis or their associates. So why are you here?
Ichigo: What's that?! I never heard about that before, Uryu!
(Y/N): Is that true?
Uryu: Training, huh? Yeah, That's right. That was the agreement. However, Urahara told me that the Soul Society refused to help you and Ichigo rescue Orihime. Therefore you are at odds with the Soul Society, and not an ally to them. You are also Substitute Shinigamis. Hence even if I associate myself with you, it doesn't go against my contract.
(Y/N): Okay, I appreciate you trying to find a loophole to help us but even I know that you're splitting hairs.
Uryu: I'd like to think of it as finding a hole in my contract.
Ichigo: That's called a forced argument!
Uryu: Shut up! Whose side are you on?
Ichigo: Your enemy's!
Chad and (Y/N) couldn't help but laugh at the two. Even though the situation was dire, there was hope.
(Meanwhile) Somewhere in the World of the Living
A man with Silver hair, wearing glasses walked into an unorthodox room. He looked at a note placed on one of the platforms in the room.
???" How typical of Ishida...
Just then another voice could be heard.
???2: Hey! It looks like Ishida ran away.
???: How did you get in? Kurosaki...
Ichigo's father, Isshin, was seen in the doorway of said room.
Isshin: Oh?! What's this? That's the first time you ever called me that. Why the change in attitude? Besides I'm not the only one who slithered in here?
Behind Isshin was (F/N).
(F/N): Geez, is this how you treat your two best friends who came to visit, Ryuken?
The man, now identified as Ryuken, didn't seem amused by the comment.
Ryuken: Answer my question... I'm asking you how you got in.
Ryuken stopped himself as he saw Isshin in his Shinigami attire.
Ryuken: That attire...You got your powers back?
Isshin: Pretty much!I look good, don't I?
Ryuken: It makes me want to throw up.
Isshin: *sarcastically* Geez, Thanks.
(F/N): Still as blunt as always. Anyways, are you going to read the letter?
Ryuken: How silly... I know what it says without having to read it.
Isshin: You let him go on purpose,didn't you?
Ryuken: It's none of your concern. I brought back his Quincy powers. Whether he makes use of it or suppresses it is up to him. Whether he lives or dies is of no concern.
Isshin: What a horrible father you are.
(F/N): Boo! Have at least a bit of love for your kid...
Ryuken: I think I'm much better than you two.
Isshin: Yeah. I know.
(F/N): Speak for yourselves, I think I'm a great father!
Isshin: Pssh! You?! Now that's a joke!
(F/N): I don't wanna hear it from the man who beats up his son.
Isshin: I never said I was a good father, now did I?
(F/N): You shouldn't be happy about that!
The three fathers (much to the dismay of Ryuken) had a lengthy conversation.
To be continued
Like I said before, I will be taking a break this week to plan out the Heuco Mundo invasion because it's so long. I want to make sure I don't contradict anything that was establish in this story or mess up anything lore wise.
