Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 278 Have you ever heard of what a top-grade cursed object is?

The endless darkness surged once more, attempting to completely engulf the figure of Mochishiro Sōya.

Tosen Kaname did not stop him, nor did he show the slightest disappointment.

He simply stood there quietly, listening to Shiro Sōya finish speaking, and then, just as his breath was about to completely disappear, he slowly took something out of his pocket.

"What if Lord Aizen had already anticipated your concerns?"

Kaname Tosen's voice rang out in the darkness.

Mochishiro Shuangye's figure, which was about to dissipate, suddenly stopped.

He turned around, his spiritual energy coalescing into perception, and landed on the object in Tosen Kaname's hand.

It was a square box.

It is no bigger than the palm of your hand, and its whole body is a dark yellow color. The material is neither gold nor copper, and the surface is covered with complicated and unclear patterns.

Even when simply held quietly in one's hands, this box exudes an aura that is... extremely ancient and sinister.

"What is this?"

Mole City Shuang also frowned.

During the years he spent merging with most of the Soul Society, he asked himself if he had seen countless rare treasures and forbidden demonic paths in Soul Society through the eyes of different people.

But he had never seen anything like it before.

This thing had no spiritual pressure or spiritual particle fluctuations, yet it possessed a power that instinctively repelled him.

"This thing was brought back by Lord Aizen from a special place."

Xin Dongxian held the box as if it were some supreme sacred object.

"You may have heard that eighteen years ago, a spiritual disaster that shook the three realms occurred in Fuyuki City in the present world."

"Although the disaster was quelled, many people are unaware of it..."

"7

That night, a small-scale spiritual disaster also occurred in Shibuya Ward, west of Karakura Town, and was quickly quelled...

97

"Lord Aizen was there that night, and that's when he received this."

Tosen's fingers gently traced the surface of the box.

The next instant, the surface began to wriggle, and slowly opened one eye.

Buzz!

A strange fluctuation swept across the entire Avici Hell in an instant.

Even Souya Mochijo, who was in a state of spiritual fusion, felt a strong dizziness under this fluctuation, as if his soul was being forcibly ripped out of this world.

"This...this is?!" For the first time, a look of shock appeared in the eyes of Souya Azashiro.

"seal."

Tosen Kaname slowly spoke, giving his answer: "This is not the Shinigami's Kido Seal that you and I are familiar with. This is more like... a conceptual cage."

Its name is—[Prison Gate Frontier].

"Prison Gate..." Shi Cheng Shuang repeated this unfamiliar name.

"Lord Aizen told me that this is a special-grade item used to seal the strongest beings."

Dongxian pushed the prison gate forward, letting its scarlet eyes pierce through the boundless darkness and stare directly at Mochishiro Sōya.

"Its activation conditions are very demanding, but once those conditions are met, it can seal away everything that exists."

"This thing cannot be opened from the inside. Only someone outside can obtain it and, with the help of special tools, release the prisoners inside."

Therefore, no matter how immense the spiritual pressure the opponent possesses, or how unbeatable their abilities are, they cannot escape.

Even if...

"6

Tosen paused, his tone carrying a chilling confidence: "Even if it's Yamamoto Genryusai Shigekuni..."

"What did you say?!"

This time, Shiro was also completely shocked.

Seal Yamamoto Genryusai?

That monster, hailed as the strongest Grim Reaper, a monster that has never been surpassed in two thousand years?

That old man who, when he gets serious, can turn the entire Soul Society to ashes?

If it could really be done...

"That's impossible." Souya Azashiro retorted instinctively, "Captain-Commander Yamamoto's spiritual pressure level is simply not something that can be contained in such a small box."

"You're still trying to understand it through the lens of a Shinigami, Kenpachi Azajo."

"6

Kaname Tosen shook his head: "This is a conceptual seal; it doesn't target the strength of spiritual pressure, but rather the existence itself."

"As long as Yamamoto Genryusai is sealed within the prison gates, even if it's only for a month, or even just a week."

"Without the Captain-Commander, the Gotei 13 is nothing but a disorganized mess, and can be dealt with easily."

"As for the enemy in the sky..." Tosen Kaname sneered, "Lord Aizen naturally has other preparations."

Zhicheng Shuang stared at the box called Yumenjiang for a long time without saying a word.

Is this true or not...

Aizen Sousuke...

Has this man actually mastered this power that transcends dimensions?

'

"What exactly do you want?" he asked.

"To reshape the order of heaven and earth, and to transform the three realms." Tosen responded, pulling Yumen Jiang back into his arms: "Don't worry, Lord Aizen knows your thoughts, and he won't force you to do anything you don't want to do during this time."

"He wants you to understand that small sacrifices are necessary for a greater peace."

"You just need to stand by his side and witness the final outcome..."

""

"At least don't take the opposite side."

A long, deathly silence fell between them once again.

Shi Cheng Shuang also closed his eyes, seemingly engaged in a fierce internal struggle.

He was considering the credibility of this matter, and also whether he and they were truly on the same path.

But the reason he remained silent in thought was because he was also well aware that deep down, that flame had never truly been extinguished.

His hatred for the corrupt nobles, his dissatisfaction with the current state of Soul Society, and his vision for his own ideals.

It has been burning silently in this darkness.

"...It's worth a try."

He slowly took a step forward, truly emerging from the darkness, and stood before Tosen Kaname.

"Although I don't trust Aizen, this really touched me."

"I really want to see for myself whether that otherworldly object can truly seal Yamamoto Genryusai."

Sōya Azashiro reached out and pulled out a Zanpakutō that looked like an ordinary Asauchi from the void.

Rain and dew pomegranates.

"I accept your invitation, Tosen Kaname."

He gently stroked his Zanpakuto, his cold expression concealing his inner turmoil.

"But please remember, the only part I will help with is destroying this rotten Seireitei."

"As for other schemes and tricks, I don't care, and don't drag me into them."

"If Aizen fails, or if he tries to betray me... I will make you pay the price in my own way."

Tosen nodded and turned to walk back the way he came.

"A wise choice."

"Welcome to the team, Kenpachi Momoshiro."

Meanwhile, on the surface of the Hidden Spirit Court.

Deep within the Fifth Division's barracks lies a secluded courtyard rarely visited by anyone.

The unrest outside seemed to have nothing to do with this place.

This place is filled with rare flowers and plants that do not belong to the Soul Society, but come from the human world.

Aizen Sousuke was standing in front of a white plum tree.

As soon as he returned to the barracks today, he was engrossed in studying the potted plant in front of him, carefully pruning its branches.

Disaster? Counterattack? Let others handle it.

Suddenly, a smile involuntarily appeared on his lips.

Click.

A soft sound.

A branch, though showing some green, fell silently into the soil because its growth direction was wrong, ruining the overall aesthetic.

"Excessive care often backfires."
