World of the Living Rescue Squad

Isshin slowly sheathed his Zanpakuto. The Hollow merely uttered an incredulous "How is this possible?" before vanishing without a trace.

At this moment, Isshin's face was only solemn, and he no longer had the eccentric behavior he had at home. He seemed to have returned to his days as the Tenth Division Captain, full of vigor and spirit.

Hun stared blankly at the scene before him, speechless. It was ridiculously strong. Was this really the same stupid father he remembered? He even began to doubt Yixin's Isshin.

"Did you succeed? Revenge?" Urahara's voice came from afar. He walked over, still wearing that green outfit and that white and green hat, and faced Isshin.

"You've arrived, Urahara," Isshin replied.

"It's been a long time, Isshin- san. It seems your skills haven't declined. That puts my mind at ease. I can't bear the blame for the weakening of Spiritual Pressure." Urahara took out his signature small fan, even though it was already autumn.

He said Isshin, "Don't worry, I won't blame you even if I become weaker. This is my true strength."

Urahara asked, "How is it? The body of a Shinigami, which has been away for twenty years?"

"So-so"

"You seem to have felt much better now."

"It doesn't matter anymore. I never really cared about that illusion. If there's anything you can't let go of after twenty years, it's the feeling of powerlessness you felt for not being able to save Masaki..."

Urahara laughed, "Still the same personality. Your son is just like you. Speaking of your son, you've noticed, haven't you? Just as you predicted, they've already crossed paths. The Visored!"

Confused, he asked, "Visored? What's that?"

Originally, it referred to a group of Shinigami who entered the Hollow realm in order to gain power, thus obtaining the power of Hollows. The only known fact is that the Visoreds and Arrancars have not yet joined forces.

Isshin sighed softly, "But they're not on our side either. After all, the Visoreds also hate Shinigami, and this Arrancar is completely different from the previous Imitation Arrancars."

"Yes, the only one capable of doing this is that man— Sōsuke Aizen! He used the Hōgyoku to create a true Arrancar, and that Hollow was just a test subject. Aizen, Soul Society, the Visoreds, and we are all preparing for this great war," Urahara said solemnly.

"Someone's coming," Urahara suddenly said. Isshin also sensed it; it was Ichigo's Spiritual Pressure.

"It's your son. It's troublesome for you to meet anyway, so let's go back. Soul and the others over there, please don't tell anyone what you saw today, okay?" Urahara said before disappearing. Then Isshin also vanished. Only a few Modified Souls remained, looking at each other in bewilderment. They then left as well, knowing that it would be difficult to explain if Ichigo saw them.

In Soul Society, the First Division suddenly convened a captains' meeting with all the division captains. This was mainly because the appearance of Arrancar in the World of the Living indicated that Aizen had begun to take action, so Soul Society also needed to take measures.

The meeting outlined the formation of a rescue team for the World of the Living. Rukia was initially selected because Ichigo was familiar with Rukia. However, Rukia alone was not enough, so Renji also went. Then, Renji recommended Ikkaku, and Yumichika felt that since Ikkaku was going, he should go too. Rangiku also joined after hearing about the matter and finding it interesting.

Then, Tōshirō led them into the World of the Living, and Ye Yang also joined them. The main reason for this World of the Living was to learn about the latest situation and to discuss the next steps with Urahara.

Finally, Ye Yang, Rukia, Renji, Ikkaku, Yumichika, Rangiku, and Tōshirō formed the World of the Living Rescue Squad, and the group came to the World of the Living through the Senkaimon.

As the saying goes, when in Rome, do as the Romans do. Since we're in the World of the Living, we'll naturally need to use Gigai and wear modern clothes. And since our mission is to find Ichigo, Rangiku suggests that everyone wear school uniforms.

Ye Yang wouldn't wear a school uniform; he bought a set of casual clothes instead. In his previous life, he preferred sporty, casual wear because it was comfortable and easy to move around in...

Rangiku said with slight dissatisfaction, "Teacher Ye Yang, weren't we supposed to wear school uniforms? Wearing uniforms is an obligation in the World of the Living, but you look much more handsome in this outfit."

"Tch, wearing a school uniform is a student's duty, I'm not a student," Ye Yang straightened his clothes.

"Huh? Aren't we going to find Ichigo? Ichigo's at school..."

Ye Yang rolled his eyes at her. "Who said I was going to school? I'm leaving first, I'll be there later, bye~" With that, Ye Yang walked away, heading towards Ichigo's house. No matter which way they went, they'd end up at Ichigo's house, right?

Isshin was still at home when Ye Yang walked straight in. Seeing Isshin, Ye Yang asked curiously, "Why are you here? Did you sneak out again?"

"How could that be? I'm out here on a perfectly legitimate mission. How have you been lately?" Ye Yang asked.

Isshin stretched her arms and legs and said, "Not bad, right? I've been in a very good mood lately. I solved a problem I've been wanting to solve for a long time. My son seems to have been quite depressed lately."

Ye Yang chuckled, "Ichigo has already contacted them, right? It's alright, your son will be fine with them around. By the way, you dealt with that Hollow/ Arrancar, right?"

At this point, Isshin's expression turned slightly serious. "Ah, you know too, right? Those were just experimental subjects sent out by Aizen. I think this matter isn't over yet; he'll definitely send out other Arrancar to World of the Living."

"Of course, so Captain-Commander Yamamoto dispatched World of the Living Rescue Squad, with Tōshirō and I leading a few people to World of the Living support. I want to see what level the Arrancar sent by Aizen is at," Ye Yang casually mentioned the purpose of his visit.

Isshin nodded and murmured, "Tōshirō, it's been so long since I've seen them..." Then footsteps sounded outside the door, presumably Ichigo had returned, and Isshin quickly disappeared.

Ichigo and Rukia walked inside, and Ye Yang said, "Ichigo, Rukia is here too?"

"Why are you here too?" Ichigo asked in surprise.

Ye Yang smiled slightly, "Why can't I come? I'm one of the captains of the support team for this mission. Since you're here, let's go to your room and discuss this matter."

"Teacher Ye Yang," Rukia greeted, then ordered Ichigo, "Ichigo, go back to your room."

Although Ichigo was somewhat confused, since Rukia had already spoken, he didn't say anything more. He took Rukia and Ye Yang back to his room. As soon as Rukia was attacked by Kon, but the consequences for her were predictable.

Upon entering the room, Ichigo immediately asked, "What's going on? Why did those guys attack us?"

Just then, a familiar voice rang out, "Wait a minute." Ichigo looked around but couldn't find anyone. Suddenly, the light on his ceiling came loose, and Renji, Rangiku, Ikkaku, and Yumichika's heads appeared on it. Then, Renji took the light off, revealing a hole in the ceiling.

Renji and the others came down from up there, and Renji even smashed Ichigo's house light bulb. "Hey, Ichigo, long time no see! I was wondering why Teacher Ye Yang wasn't with us, turns out he arrived a while ago."

Ichigo, however, paid no heed to any of that, veins bulging on his forehead. "What have you guys done to someone else's light bulb?!"

At that moment, Ikkaku was upside down, Rangiku smiled, pointing at Ikkaku's bald head, "It's nothing, I was just trying to change a light bulb."

"What did you say?"

However, Rangiku directly slapped him in the face for saying that. Although Ikkaku was indeed very strong, Rangiku had a trump card to deal with him: Rangiku was very familiar with Yachiru, and Ikkaku had no way to deal with Yachiru. Ikkaku would be afraid whenever Yachiru was mentioned.

Ichigo ignored the farce and asked, "What exactly are those things that came to the World of the Living this time? Are they Hollows? But why don't they have masks?"

Renji explained, "They are Arrancars. Arrancars are Hollows who have removed their masks and gained the power of Shinigami. Originally, there were very few Hollows like them in Hueco Mundo, and they were all incomplete. However, because Aizen contacted them with the Hōgyoku, complete Arrancars were born. Those were the two you met before. Do you understand?"

Ichigo nodded and said to Rukia's drawing, "I understand. I would understand better if it weren't for that doodle."

Rukia threw the notebook at Ichigo's face, but since they were still discussing serious matters, neither of them said anything more. Just then, Tōshirō's voice came from outside the window, "You really didn't keep an eye on him, Ichigo Kurosaki."

Tōshirō continued, "Arrancars are indeed created by Hollows by removing their masks, but ordinary Hollows aren't much of a threat even after removing their masks, so Arrancar transformation should be limited to those above the level of Menos Grande."

Ichigo was even more puzzled, "What? There are Hollows even higher than Menos Grande?"

Ye Yang continued, "The Menos Grande are indeed the highest level, but there aren't three levels of Menos Grande. The first level is what you saw as the Gillian. They are enormous, but they lack reason and thought, and they move slowly. They are at the bottom of the Menos Grande. All Gillian are the same form, and in Hueco Mundo, they can only be considered low-level grunts."

Ichigo exclaimed in surprise, "What! Those were just grunts?"

"Yes, that's the one you just drove away from the World of the Living after gaining the power of the Gillian. Menos Grande of that level has absolutely no status in Hueco Mundo. There are thousands upon thousands of Gillian in the Forest of Menos!"
