In the novel " Shinigami the Unforgiven," Chapter 29, "Breaking into Silbern Shiraishi," Shiraishi could have rescued Kisuke Urahara and ended the Silbern arc by himself, but he didn't. Naturally, he wanted to train Ichigo Kurosaki more.
Secondly, it's about saving face for the Wandenreich.
The ultimate goal of this trip is not to defeat Yhwach, but to form an alliance to fight against Aizen together.
It's like the Three Kingdoms period of vying for supremacy.
Aizen represents the strongest Kingdom of Wei, which was essentially the Kingdom of Shu before it lost Jing Province. They possessed the strength to fight Kingdom of Wei one-on-one, but they had to guard against a sneak attack from Kingdom of Wu.
Because of their battle with Aizen, regardless of victory or defeat, it was foreseeable that they would be severely injured and weakened.
At that time, if the fully-powered Wandenreich came to Momo, who could stop them?
If we're going to fight, let's fight together.
As for focusing fire to destroy the Wandenreich, that won't be an easy task either.
The Sternritter are definitely not weaklings; at the very least, Yhwach can restrain Shiraishi's actions.
Among the rest of the Schutzstaffel and Knights, there were quite a few who could go toe-to-toe with the captain.
If things really turn sour, Shinigami can't deal with them quickly enough, Aizen could come Momo, and the consequences would be even more severe.
Forming an alliance is the safest way. If we fight Aizen together, everyone will be low on health, which is practically the same as no one being low on health.
"Okay, I'll do as you say."
Upon hearing what Shiraishi said, Ichigo Kurosaki stopped objecting and obediently followed the arrangement.
In this respect, he knew he couldn't compare to these experienced captains; all he had to do was fight.
Soi Fon rolled up the map and said, " The Lloyd Brothers, who are in charge of guarding the area, will be dealt with by Captain Unohana and me. As for the rest, I'll leave them to you."
"Yes." Ichigo Kurosaki.
"I'll prepare some sleep-inducing tea so everyone can relax and get a good night's sleep."
Retsu Unohana stood up and vanished from the spot using Shunpo.
Shiraishi bluntly ordered, " Orihime, could you please wash the bowls and plates?"
"OK," Orihime Inoue replied confidently.
No matter how big or small the matter, she is willing to do anything that can help people, supporting everyone fighting in this way.
I'll go too.
Soul took short strides, trying to catch up, and bracing himself for a devastating blow from above.
He ran out the door, then realized with surprise that something was wrong. He turned around and asked, "Big sister, why didn't you stop me?"
Normally, shouldn't you have stepped on it much earlier?
"Oh." Rukia reacted, belatedly stepping on Soul's head and rubbing it casually.
Soul yelled, "No passion at all! Don't underestimate trampling, big sister!"
Shiraishi said, " Rukia, don't be too discouraged. Not everyone can complete Bankai training within three days."
"Yes."
The completed Ichigo Kurosaki echoed.
"Yes, I know, you don't need to worry about me."
Rukia forced a smile, stretched, and said, "Oh dear, I'm sleepy. I'm going back to sleep and rest."
Before they could speak, Rukia ran away. Only she knew why she couldn't pass the Bankai training.
She couldn't overcome her fear.
Soi Fon frowned slightly and said, "She's no good. She's in even worse shape than that lazy Ōmaeda. Let's just kick her out of tomorrow's operation and replace her with Ōmaeda."
Upon hearing this, Hun immediately jumped onto the table and objected, "Wait, wouldn't that make eldest sister even more disappointed?"
Soi Fon retorted, "Do you think her feelings are more important than her life? Battle is no child's play!"
"..." Hun pursed his lips, unsure how to object, his mind filled with confusion. He didn't want to see his older sister's dejected state, nor did he want her to die.
Unable to handle it himself, Soul decisively sought outside help. "Mr. Shiraishi, Ichigo, Chad, say something too!"
Ichigo Kurosaki and Yasutora Sado were equally at a loss for words; they both knew that Rukia was indeed not in good condition.
Shiraishi thought for a moment and then said, " Soi Fon, some people fall all the way down, while others bounce back after hitting rock bottom. I believe Rukia is the latter."
" Ōmaeda, that guy has no hope at all; going up there is just suicide."
"Hey, watch your tone. He's my vice-captain, after all."
"Didn't you used to complain all the time that that guy had nothing but business and money?"
Soi Fon sighed, "He has no business back home now, and he has no money left."
"... This is indeed a heavy topic. In short, I agree with letting Rukia participate; I believe in her potential."
With Shiraishi so supportive of Rukia, Soi Fon had no choice but to abandon her idea of having Ōmaeda take her place, and said with a helpless expression, "Fine, it's your choice."
Retsu Unohana returned to the hall, without the tea meant to help people sleep.
Shiraishi asked in confusion, "Where's the tea?"
She said gently, "That's for Rukia, to help her get a good night's sleep, not for you."
"Oh, then I'm going to sleep." Ichigo Kurosaki stood up. With Orihime Inoue constantly healing him, his body could hold on, but he was still mentally exhausted and really wanted to get a good night's sleep.
I'm going to sleep too.
Soi Fon had been under immense pressure, constantly gathering intelligence behind enemy lines, and Robert's sudden fright almost caused her heart to stop.
At that moment, she truly thought she was going to die. Later, she was rescued by Shiraishi. Overwhelmed with joy and fear, she became increasingly exhausted.
Having finalized her plans for tomorrow, all she wanted was a good night's sleep to recharge.
Yasutora Sado also stood up.
Retsu Unohana blew out the lights in the hall and said with a smile, "Good night."
"..." Shiraishi sat blankly on the stool, lost in thought. Who should he sleep with tonight?
Retsu Unohana and Soi Fon, they're both here.
Neglecting one over the other is inappropriate; if you take turns, the fragrance on your body will attract the other's attention.
Shiraishi covered her face with her hands, deciding to sleep alone tonight.
Moonset and sunrise.
It's dawn again.
Daylight broke, and the pale white of dawn rose from the east. The sun, which had not yet appeared, had already driven the night out of the sky.
After a quick breakfast, the group began their plan to infiltrate Silbern, blending into the convoys that transported food and supplies there daily.
The Quincy the gate gave a quick look and then let them pass without a second thought.
They couldn't stop any enemy who dared to infiltrate Silbern.
The gatekeeper's real duty was to maintain order and prevent the food delivery convoys from cutting in line or causing arguments among the convoy members, thus delaying the Sternritter's mealtime.
Having infiltrated Silbern, the caravan continued forward. Shiraishi lifted the curtain and slipped out, not traveling with Retsu Unohana and the others.
He landed alone atop a spire, gazing at the Silbern in the center. He stroked his chin, sensing that the Reishi around him was not quite right.
It felt like countless eyes were staring at you from all directions.
I didn't get that feeling at the door last night; it seems that Haschwalth's mask of a ruler is not as strong as Yhwach's real one.
His gaze drifted to the Ice Palace atop Silbern, and a smile spread across his face. "Nice to meet you, Yhwach. My name is Shiraishi. Please take care of me."
