After Ulquiorra and Yammy made their exit I handed a Senzu Bean to Ichigo so he could recover and Orihime to focus on healing Sado. Since I interrupted Yammy from further beating on Ichigo and then slap away Orihime when she tries to stop him, she didn't get hurt. Not much could be said for Sado though, so Orihime just needs to heal Sado. Yoruichi and Urahara finally made it to the scene.
Urahara: What did we miss?
Sage: Pretty much all of it. Is there a way to revive these people Urahara-san?
Urahara: I am afraid not, they were too weak spiritually so being in the presence of beings with extremely high spiritual pressure such as the Arrancar, would cause them to faint and if they stay further they would die, but by the looks of things they sucked their souls no matter how weak.
Sage: Oh well. I guess they were meant to die.
Yoruichi: I'm guessing you fought off the ones that came through. How was their strength in comparison to us?
Sage: Honestly or optimistically?
Yoruichi: Honestly.
Sage: In comparison with you two, if you had activated Shunko you could have finished the big guy before he uses his Ressurreccion, if you let him use him release then it could go either way. The smaller guy was a different level than the big guy so if you and Urahara could team up you might take him, but again, that's before his Resurreccion.
Yoruichi: What about after his Resurreccion?
Sage: If Urahara-san uses his Bankai, then you could have a chance.
I could tell that she didn't like what I said and Urahara held his hat to his face. They knew their chances were slim to none.
Urahara: If our chances were so dismal, why didn't you kill them?
Sage: And what? You want me to hold your hand with a nightlight as well while you sleep? Adversity will make you stronger, especially my confused friend here.
I kicked Ichigo on the back of his head as he watched Orihime heal Sado. From the way he looks, Ichigo felt responsible for what happened to Sado, like he always does. I shook my head and told them that I will take Tatsuki home. Before I left I told Orihime to let me know when Sado is healed so I could train him. Sado had been one of my favorite characters that was sidelined in this universe too many times so I thought it would be interesting to see him fight better and stronger opponents than Ishida or Renji. I wanted Sado to at least be relied on by Ichigo instead of him being another person that needs to be rescued.
When Sado was done being healed, Orihime let me know through one of her Shunshun Rikka. Ichigo didn't need to be healed because of my Senzu Bean, so there was no delay in telling me. Once I arrived at Urahara's shop where Sado was being healed, I wanted to talk seriously with him.
Sage: Sado, I am going to ask you a very simple question. Do you want to become stronger?
Sado: (In a firm voice) I do.
Sage: Good. I can make you far stronger than you can imagine but the progress is up to you. Since we are pressed for time I will have to create some. (I turned to Urahara) Urahara-san, can I borrow the space in your shops basement?
Urahara: Sure, but I am interested in your training process. Do you mind if I sit in?
Sage: Nah, come join. Maybe this youngster can teach you a thing or two.
We headed into the giant training area where we left through Urahara's make shift Senkaimon. I wanted to utilize as much space so that we can train to the fullest. Once I figured out the layout of how much space I wanted to use I could at least know how much power I will be using. I created a Back Channel encompassing the area needed. A Back Channel is an alternate realm between the physical world and the World of Souls, where time and space work differently. However unlike the World of Souls, time still flows in the Back Channel, thus allowing living beings to enter it without repercussions.
The Back Channel was produced when ANOTHER exceeded the speed of light in order to escape Moon, causing it to create these paths through space and time. There are several ways to enter the Back Channel. Entry into the Back Channel is no simple task itself as normal individuals cannot even detect it. The mystery behind the Back Channel lies in the fact that it was a spatial anomaly created by ANOTHER, resulting in its few entrances being impossible to find.
By eating PAIR, one can see through the Back Channel and even enter it, as well as see and communicate with Food Spirits, as PAIR's second half falls within the Back Channel. However, if one eats NEWS, they can even create Back Channel space and enter it wherever they desire, by making their cell division speed surpass the speed of light. Again, thank you Acacia's Full Course.
Since I have my own personal Hyperbolic Time Chamber, I can train Sado for a good amount of time before we head to Hueco Mundo. My only problem is figuring out what the time difference that we can spend in my Back Channel. Since we have a few weeks I can figure it out then by staying in the Back Channel for an hour. After knowing the time difference I can set a max of a 100 years for 1 day in the Back Channel. Comparing myself to the power of the Sky Deer or Deer King, one of the Eight Kings in Toriko, I can also accelerate the time making time around me go slower or faster.
I adjusted the time in the Back Channel area to 100 days to 1 Day outside the area. Urahara was amazed by my ability and pestered me to let him analyze me. I told him that through me traversing through universes I encountered food that gave me this ability. After calming down and informing Yoroichi about my ability, I began training Sado. I gave him a Senzu Bean to keep him from eating for at least 10 days in my Back Channel. I started training him under Dragon Ball rules while under heavy gravity. When the Senzu Bean had run its course I began cooking normal food with Reiatsu infused into it, now that his body has been forged I can maintain it with the food and increase his capacity at the same time.
Yorouichi and Urahara came to train every now and then but I think it was mostly to partake in the food. I didn't push Sado too roughly since he is still human and, despite how he looks, he is only 15 years old. I taught Sado a movement technique like Shunpo because he has mastered the use of Reiatsu. Since Sado's power was similar to a Hollows', I also taught him to use a similar technique to the Bala or Bullet that the Arrancar fire with compressed Reiatsu instead of a small Cero within the few years we were in the Back Channel. I didn't get a chance to leave because I didn't want to disrupt Sado's training so I had either Urahara or Yoruichi to buy food for me to cook. Because the food from Toriko's universe would probably kill them through the energy alone, I didn't use any so I infused normal food with Reiatsu.
Sage: So, how do you feel Sado?
Sado: Sage-san, I feel haggard.
Sage: Haha, don't worry, once we get out of here just eat normally, rest up and you will feel the difference. Once you do you will have to readjust your strength to your surroundings.
Sado: Do you really think all the training I did would make that much of a difference?
Sage: Of course! The added weight made you faster, endure more pressure and, naturally, stronger. My clones fought you the entire time and unlocked more of your power. You thought that you could only use your left arm but now it looks more like a full body suit or armor.
Sado: I can't feel myself while we are in here but I can see the difference. Thank you.
Sage: Don't thank me yet. Thank me when you're holding the head of the guy who tore your arm apart and shoved it up his ass. Make him regret picking a fight with you.
Sado looked at me in disbelief but I could tell that he has grown far stronger than he was in the original, even more so than when he had transformed both his arms. I figured that if he could Full Bring both arms he could do the same to his whole body. I told him to think of his power as a suit of armor. So, the training involved his whole body not just his arms. I also told him to measure his enemies by the amount of armor he equips, so the stronger the more armor he puts on. I can't wait to see everyone else's faces when they see Sado in action.
