Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 364 Interdimensional Spiritual Power That Cannot Be Shared

Asuka and her companion hurried along, and as soon as they stepped into Sarayashiki City, which Urahara had mentioned, they immediately sensed something was wrong.

"Bird! The air here... feels off?"

Sensing the depletion of spiritual energy around her, Shinobu Kocho frowned and quickly offered a reminder.

Following her instructions, Asuka sensed it and indeed, she could hardly detect any spiritual particles in the atmosphere.

"It could be due to the influence of the otherworldly environment..." he analyzed, recalling his previous experience in Fuyuki City.

In Fuyuki City, the atmosphere contained a magical energy that resembled spiritual energy but was not quite spiritual energy.

Although it can be used as spiritual energy, there are often many limitations.

Not to mention that during the demon era, simply releasing the limits of spiritual pressure almost burned away his own spiritual remains.

It seems that a similar situation exists in Sarayashiki City, where the concept of spiritual power appears to be confined to the human body.

Although Shinobu Kocho can still draw upon her spiritual energy, such a barren spiritual energy field would likely only be able to support a few low-level Kido before the supply of spiritual energy is cut off.

He grabbed Shinobu's hand: "...It might be due to the influence of the otherworldly environment. Are you still able to move? Should we leave and wait for me to come out?"

"No!" Shinobu Kocho immediately refused, "Don't underestimate me. Even without spiritual power, I'm still a dignified swordsman."

"On the contrary, Asuka, it seems like you're not affected at all."

Just as Shinobu Kocho said.

Although the spiritual energy environment was depleted, the spiritual energy within the bird's body, apart from remaining restless and difficult to control, did not show any obvious abnormalities.

For him, these changes in the rules of other worlds were not the first time, and he was fully capable of adapting to them.

"...Maybe it's because I've seen so much in battle," he replied uncertainly. "Since the environment here is special, don't act rashly. I'll protect you."

"Um!"

The two walked side by side and soon arrived at the meeting place they had agreed upon with Yoruichi.

Just as Asuka had expected, Yoruichi's expression wasn't very pleasant either.

She was sitting cross-legged on a dilapidated paint bucket on the street corner, her face etched with exhaustion.

After two days of monitoring and investigating in this barren spiritual energy field, even though this instant god relied more on footwork and free-style fighting, he was feeling somewhat physically and mentally uncomfortable.

"Oh, you two have finally arrived... any later and this old body of mine might have given up here." She greeted them humorously.

"Miss Yoruichi, are you alright?" Upon seeing this, Shinobu Kocho immediately rushed forward to check on Yoruichi's condition.

Yoruichi waved her hand, stopping Shinobu Kocho from getting closer: "Stop, stop, stop, I'm not hurt, little Kocho."

"You guys felt it too, didn't you? The spiritual energy field here is as clean as a plate that Kisuke, that starving ghost, licked clean."

"I've been keeping watch here for two days, relying solely on my basic fighting skills and footwork to navigate through those hordes of spirits. It's been incredibly tiring."

Yoruichi jumped off the paint bucket, dusted off her trousers, and walked up to the two of them.

"But seeing you two holding hands and walking in like you're strolling through a temple fair, I feel much more at ease." She smiled slyly, "It seems Kisuke's analysis was correct. Only your physique can adapt to these troublesome laws of another world."

"

"...Let's get down to business, Yoruichi-sensei." Asuka released Shinobu's hand, her gaze sweeping over the distorted, grayish-white world. "What's the actual situation here? Who do I need to kill?"

Yoruichi dropped her joking expression and became serious.

"The situation might be worse than Kisuke told you."

She walked to the side of the street and pointed to the city shrouded in thick fog: "Two days ago, when Kisuke first detected this fissure, it only existed in the downtown area."

"The fog wasn't very dense back then; ordinary people would have just thought it was a sudden smog event." Yoruichi's golden eyes flickered with unease. "But now, look again."

Following her gaze, Asuka noticed a gray curtain wall that stretched from the sky to the ground above the city.

The curtain wall is like a living thing, expanding outwards at an extremely slow but perceptibly visibly pace.

"In just two days, it has spread from the central area to almost the entire urban area of ​​Sarayashiki City, even faster than Kisuke predicted."

"If we don't find a way to shut it down soon, at this rate of expansion, this grayish-white fog will spread to the neighboring Karakura Town within a week..."

"And then, the entire Kanto region... and even the entire present world."

The future depicted by Yoruichi made even Asuka, who was usually indifferent to external affairs, realize the seriousness of the problem.

"The mortal world will be overwritten..." Shinobu Kocho murmured in shock, "The entire human world will become a barren wasteland devoid of spiritual energy?!"

"Not bad!" Yoruichi stretched out her hands and drew a circle in the air: "Soul Society, the Human World, Hueco Mundo. The reason these three worlds can exist stably is because the Creator created a dynamic cycle between them."

"When people die in the mortal world, their souls are guided by Shinigami into the Soul Society; after the souls in the Soul Society dissipate, they are transformed into spirit particles and reborn into the mortal world; even Hollows that fall into depravity without guidance can be purified after being killed by Shinigami and return to the cycle."

"But once the connection to the mortal world is severed, without the guidance of the Grim Reaper..."

Shinobu Kocho revealed the ultimate fate: "The balance of the three realms will completely collapse... Our world may be coming to an end!"

"Why didn't this unscrupulous merchant say something so important sooner?" Asuka was speechless. Why was he being so evasive at a time like this?

He originally thought it was just a local disaster, but he never expected it to turn into a catastrophe that could destroy the world.

"That's just how Kisuke is, you'll get used to it." Yoruichi shrugged helplessly.

Asuka gripped the hilt of her sword tightly and said urgently, "Since the situation is so urgent, let's not waste any more time. What should I do?"

"Urahara said there's a spirit detective causing chaos here, and he wants me to go kill him first?"

Upon hearing Asuka's menacing suggestion, Yoruichi couldn't help but feel exasperated.

"Hey, hey, hey, can't you think of anything other than killing people? Why do you always want to kill people!"

'

Yoruichi quickly waved her hand, trying to extinguish Asuka's murderous intent: "Don't do anything rash! That Spirit Detective isn't an enemy, he's actually our ally!"

"An ally?" Asuka frowned. "Didn't Urahara say this guy was a problem?"

"Sigh, we can't entirely blame him." Yoruichi sighed helplessly. "The situation with the valley is new to them too. Their boss over there was probably just desperate and sent this greenhorn to deal with the soul-destroying one."

"He did cause a lot of trouble; the large-scale energy burst made the edges of the rift even more unstable... but his original intention was to protect his present world, to protect his friends and family."

"He thought that he could solve the problem by smashing all the ghosts that appeared on the street, but little did he know... that this would only make the situation worse."

"Therefore, the best way to deal with him is to communicate and make him understand the real problem, rather than cutting him down."
