Farewell, Aizen

Urahara Kisuke the jar Kaien Shiba's spirit to Rukia for safekeeping. The person he and Tsuna were about to meet was someone Rukia was not allowed to participate in.

While Kaien Shiba was still conscious, he concentrated all his spirit in one place. Then, Tsuna used Storm Attribute Flame to completely disintegrate Aaroniero's body and obtain the part of the spirit that belonged to Kaien Shiba.

Since Kaien Shiba was devoured by Aaroniero for many years, his spirit body must still contain other spiritual pressures, but these are not important matters. They can be gradually extracted after Tsuna returns.

Next, Ichigo will lead a few people away from Las Noches with Nel's subordinates and hide far away. If Tsuna and Urahara do not communicate with Ichigo within the agreed time, the device that Urahara gave to Ichigo will open the Garganta leading to the World of the Living.

"No, Tsuna, didn't you say there was absolutely no danger?" Ichigo asked somewhat uneasily, clutching a triangular device to his chest.

Ichigo can also activate this triangular device, which can also open the Garganta and take them away.

"Aizen is too much of a threat to us right now, but we can't be sure if his subordinates have other ideas. If there's any danger, you should go back first. The shopkeeper and I will be fine," Tsuna explained.

Tsuna's main concern is Barragan, the former King of Hueco Mundo and now the Espada. Unlike Ulquiorra, this Arrancar is not loyal to Aizen. If Aizen becomes weak, he might just turn against him.

Furthermore, Barragan's abilities are not easy to deal with; if they were to face him, leaving Hueco Mundo would be the best option for Ichigo and the others.

"But isn't Inoue -san still here?"

"Don't underestimate me. I can only say a few words about everyday matters. If a mutiny really breaks out, I can't handle those guys up there," Sora Inoue said with a wry smile.

Sora Inoue is essentially still Adjuchas, and he has almost no chance of winning against several Vasto Lorde.

"Don't make things difficult for Inoue -nii. We'll need him in Hueco Mundo for a while, so let's not let him clash with his colleagues," Tsuna advised.

"Alright then, be careful, don't expect us to come and save you," Ichigo said, arms crossed.

Tsuna and Urahara exchanged a glance and laughed. Tsuna then said earnestly to Ashido, "Mr. Ashido, please bear with Ichigo's temper."

"Tsuna!"

Before Ichigo could get angry, Tsuna pulled Sora Inoue towards the depths of the palace. Ichigo shouted a couple more times, but after realizing it was pointless, he led the others to find a safe place Las Noches.

"Inoue, you can register the Espada Szayelaporro. He died at the hands of the Squad 12 Captain Kurotsuchi Mayuri," Urahara said to Sora Inoue after glancing at a communication device.

By informing Urahara Kisuke Kurotsuchi Mayuri also telling Tsuna that he had returned to Soul Society, and that opening a Garganta was a piece of cake for Kurotsuchi Mayuri.

"Szayelaporro? You killed him?" Sora Inoue's face lit up with joy.

"What? You hate him too?" Tsuna asked curiously.

"There was nothing I could do. He was a guy who enjoyed toying with other people's lives, and he even called it 'for the sake of a perfect life.' I've felt his gaze on me more than once."

Sora Inoue was still shaken. "Fortunately, because of my work experience before my death, I have some ability to handle trivial matters, so he was hesitant to lay a hand on me since I have gained Aizen's favor."

"Many Arrancar in Las Noches have suffered at the hands of Szayelaporro. Unfortunately, the Hollows respect the strong, and every time Szayelaporro causes a research accident, it can only be left unresolved. It's a real headache for me."

As a de facto steward of Las Noches, Sora Inoue is most annoyed by these Arrancar who use their power to cause trouble. He can't say anything to them because of their strength, and if he reports it to his superiors, Aizen will ignore it.

This forced Sora Inoue to spend a lot of energy on mediation, and no one in the entire Las Noches dared to disrespect this nice guy.

"Sora Inoue, are you colluding with the enemy?"

It was clearly a question, but the speaker's tone was completely calm. The one who emerged from the shadows was the 4th Espada, Ulquiorra.

"Don't say that. I'm just inviting you two to meet at Lord Aizen's request," Sora Inoue said, waving his hand.

Upon hearing that it was Aizen's arrangement, Ulquiorra had no further questions. He walked past Sora Inoue and the others, but his gaze remained fixed on Tsuna.

Although it was just a fleeting glance, Ulquiorra still recognized Tsuna's appearance. After returning from Soul Society, he had also crushed his own eyeballs and studied and reviewed Tsuna's fighting style with Stark.

Ultimately, Ulquiorra could only conclude that he should compete with Tsuna in terms of the speed of his Lanza del Relámpago attack, but there was a greater possibility that he would be defeated by Tsuna.

"Are you going to rescue Yammy? Don't waste your energy. Lord Aizen said to ignore the Arrancar."

As a know-it-all of Las Noches, Sora Inoue immediately saw through Ulquiorra's thoughts. As a friend, Ulquiorra must have sensed Yammy's spiritual pressure and was preparing to go and support him.

"Yammy is only temporarily suppressed and is not in mortal danger. He will be rescued after the guests are seen off."

With Sora Inoue's assurance, Ulquiorra paused for a moment and changed direction. Although he didn't say it, he didn't dare disobey Aizen's orders.

"Let's go."

Sora Inoue continued to lead the way, and as they passed through a central hall, Tsuna and Urahara immediately felt three sharp gazes.

"Inoue, you're not planning to ambush us, are you?" Urahara Kisuke asked in a sinister tone, his face expressionless.

"Manager, even if you don't believe me, you should believe in Lord Aizen's magnanimity." Sora Inoue looked up and scanned his surroundings. There were two corridors on the second and third floors, one of which was blocking their way.

Tsuna didn't seem nervous at all. While Sora Inoue was speaking, he had already distinguished the three factions. Upstairs were the Espada Barragan, and the Third Espada, Halibel.

One was a burly old man with a scar, and the other was a blonde, dark-skinned mature woman with her face half-covered, revealing her southern hemisphere.

As for the guy blocking their way, it turned out to be Stark, the most annoying 10th Espada, along with Lilynette was snarling and baring her teeth beside him.

"Are the three of you waiting here on Lord Aizen's orders?" Sora Inoue was the first to question them. If it wasn't Aizen's order, he could immediately demand that they leave.

"Las Noches has been provoked, can't we even come and take a look?" Barragan questioned. Although he didn't dare to openly rebel, he still disliked this guy who kept mentioning Lord Aizen.

Hearing Barragan's words, Sora Inoue actually breathed a sigh of relief. Barragan's words proved that they were not there to cause trouble.

"Then I'll trouble the three of you to return to your palaces first. These are Lord Aizen guests. I'll take them to see Lord Aizen first," Sora Inoue said in a consultative tone.

"You can go, but that hedgehog-headed guy has to stay!"

Stark covered his eyes, feeling a slight headache. In such a serious moment, only Lilynette dared to speak up, but Lilynette was his other half, so he could only indulge her.

"Sorry, Lilynette has been holding a grudge about the last battle. If possible, could you fight us again?" Stark swept a strand of hair that was covering his eyes behind his back, revealing a serious look in his eyes.

In fact, not only Lilynette, Stark himself often thinks back to that battle, Tsuna was the first opponent to break through his infinitely reloaded Cero.

Even the lazy Stark, who disliked fighting, was ignited with a fighting spirit after being defeated in his area of expertise.

"A fight? I didn't expect it would be you who initiated it." Tsuna slightly surprised. Could it be that he had finally enlightened Stark? "But not yet, let's wait until we've met Aizen."

"Is that so? Lilynette and I will wait for you outside the palace." Stark said, patting Lilynette on the shoulder, mainly because he was afraid that Lilynette would be unreasonable.

Lilynette was reckless, not stupid. Once she heard it was related to Aizen, she lost all interest in getting involved. Anyway, Tsuna had already agreed to their request, so it was just a matter of waiting. She and Stark had plenty of time.

Stark had no intention of starting a fight immediately, and the two upstairs had even less excuse to cause trouble for Tsuna, so they could only watch Tsuna and the others leave.

Passing through the surrounding side halls, Tsuna companions entered the central palace of Las Noches. Even without any superfluous decorations, the brightly lit hall exuded an overwhelming sense of grandeur.

It can only be said that Aizen is indeed worthy of the name. No matter where he goes, he will not compromise himself. In Hueco Mundo, which can only be described as desolate, he was able to build such a large palace.

Tsuna and the others could even see Aizen, they heard Aizen voice drift over, "Long time no see, Sawada Tsunayoshi, Urahara Kisuke."

Looking up, at the back of the main hall, on the towering steps, there was only a white throne. Aizen was sitting with his legs crossed, one hand supporting his head, using the terrain to his advantage to raise his aura as he stared at Tsuna and Urahara.

"Hey, long time no see, Aizen." Tsuna completely ignored Aizen's oppressive aura and greeted Aizen casually, like a long-lost friend.

Urahara's lips curled into a helpless smile as he gently adjusted his hat in a gesture of respect. Having Aizen for over a century, he couldn't possibly face Aizen with a completely calm mind.

After bringing Tsuna and Urahara, Sora Inoue bowed and quietly left. Having good judgment was the rule that allowed him to survive in Las Noches.

"Then, let me hear what you two want from me?" Aizen sat up straight, his deliberately created aura failing him, and he was too lazy to pretend anymore, so he asked seriously.

"No, before we talk about that, is this your way of treating guests?" Tsuna raised his hand to his eyebrows, feigning surprise as he looked around. "Old Man Yamamoto knows to serve tea, surely the king of Hueco Mundo doesn't have anything to offer?"

"Ha, I dare to serve tea, do you dare to drink it?"

Although Aizen's tone was somewhat disdainful, his actions were anything but slow. A burst of spiritual pressure shot out from his fingertips and landed in front of Tsuna and Urahara.

The palace floor rose and changed, and two chairs appeared in front of Tsuna and Urahara. This was Aizen's way of treating guests. As for serving tea and such, it can only be said that Hueco Mundo did not have such a custom. Anyway, he was the King of Hueco Mundo, and everything was up to him.

Tsuna and Urahara exchanged a glance; they both recognized the nature of that spiritual pressure.

Tsuna frowned, looking at him strangely, and asked, "Wait, you're using the Hogyoku's power like this? Then I'll have to seriously consider whether I should cooperate with you."
