Detective Conan: Birth of the Demon Child

Kyojuro Rengoku brandished his Nichirin Blade and sneered, "Knowing beforehand that it was a dream, your Blood Demon Art is useless against me!"

The reason why Rengoku Kyojuro couldn't distinguish between reality and dreams was because it was the first time he had encountered a Blood Demon Art related to dreams.

Now that he's on guard, even if Enmu uses Blood Demon Art to pull Rengoku Kyojuro into the dream again, he can break free from the dream instantly.

"The Pillars of the Demon Slayer Corps are indeed not so easy to kill! But aren't you curious why I'm still alive after my head was cut off?"

A fleshy tentacle as thick as an arm suddenly emerged from the train, connecting to Nightmare's severed head and lifting it up like a snake.

Seeing Rengoku Kyojuro's slightly furrowed brows, Enmu didn't keep him in suspense. Instead, she sneered and said, "The reason is actually very simple. While you were all fast asleep, I had already become one with this train. So the head you cut off wasn't my real head; it was just a part of my body."

In other words, all two hundred-plus passengers on this train are now inside me. Do you really have the ability to protect these passengers while searching for my core and killing me?

Time is running out for you~ The decision is yours: save the innocent passengers first, or find my core! Hahaha…”

Amidst Kyojuro Rengoku's utterly grotesque expression, Enmu's head and body completely dissolved into a pool of bloody, fleshy pulp, merging into the train beneath his feet.

"Ding! Congratulations on successfully signing in to Nightmare. You are rewarded with a copy of 'Nightmare Technique'. You can claim it at any time."

As Nightmare merged with the train beneath Suzuki Seimei's feet, a system notification sounded in his ear.

(??ω??)

After reviewing the skill attributes of "Nightmare Technique", a glint flashed in Suzuki Seimei's eyes.

Suzuki Seimei just experienced it firsthand; the dream that Nightmare created was so realistic that it was unforgettable.

Now that Suzuki Seimei has mastered the "Nightmare Technique," many ingenious ideas are popping into his head. He no longer needs to worry about how to guide Ai Haibara and the others onto the path of transcendence after returning to the main world.

Suzuki Seimei could directly pull Ai Haibara and the others into a dream, and then impart extraordinary abilities to them through a dream-based spiritual transmission.

"Brother Kyojuro, I'm leaving the task of protecting the hostages to you. I'm going to find that guy's core!"

As soon as Suzuki Seimei finished speaking, he vanished in a blur, giving Rengoku Kyojuro no chance to refute him.

"boom!!!"

Without another word, Rengoku Kyojuro cleaved open the train roof with a single slash, rushed into the carriage, and severed the fleshy tentacles that were trying to devour people at top speed.

The "Mega" train has a total of twelve carriages. Even a "Pillar" would have to exert all his strength to protect more than two hundred innocent passengers from so many fleshy tentacles.

At this moment, Rengoku Kyojuro felt mostly fortunate. If Suzuki Seimei hadn't accompanied him this time, he might have really perished here.

After all, protecting the two hundred-plus passengers on the train would be enough to keep Rengoku Kyojuro busy, leaving him no chance to search for the core of Enmu. He would simply be worn down to death.

"Whoosh whoosh..."

Just as Rengoku Kyojuro was doing his best to protect the innocent passengers, Suzuki Seimei also switched his breathing frequency to "Thunder Breathing," his entire body wrapped in visible golden lightning, and he rushed to the engine of the train as if he had teleported.

Thunder Breathing - First Form - Thunderclap Flash!

"boom!!!"

With a deafening clap of thunder, Suzuki Seimei, wreathed in lightning, transformed into a golden bolt of lightning and wielded the Demon Slayer Sword, slashing towards the locomotive.

"Do not!!!"

Sensing a deadly threat, Nightmare controlled hundreds of tentacles covered in eyeballs and blasted towards Suzuki Seimei.

As soon as Suzuki Seimei's gaze meets any of the eyes on these tentacles, he will be instantly pulled into a dream by Nightmare, and his sword moves will naturally be interrupted.

However, to Yanmeng's surprise, just as he was about to forcibly pull Suzuki Seimei into the dream, he was suddenly horrified to find that Suzuki Seimei's eyes were tightly closed.

"Pfft!!!"

Without pausing, Suzuki Seimei, who had transformed into lightning, instantly severed hundreds of fleshy tentacles blocking his path, and at the same time cut off the locomotive with a single sword strike.

"Ah ah ah..."

Amidst the Nightmare's unwilling howls, the locomotive was instantly cleaved in two, and the "Infinity" train, having lost its engine, also lost control.

"Rumble..."

Driven by inertia, the train carriages sparked brightly as they rubbed against the rails, eventually derailing and crashing onto the open ground outside the tracks.

Chapter 525 Upper Moon Three: Akaza (Third update, please vote)

Fortunately, trains in this era were slow; otherwise, even if Suzuki Seimei had killed Enmu, the passengers in the carriage would not have survived.

"My body...my body is disintegrating, it can't regenerate, oh...oh, this is terrible..."

From the remnants of the nightmare's flesh, an eye slowly opened, staring intently at the unharmed Suzuki Harumi, and cried out in a voice filled with resentment, "This... what a nightmare this is..."

"boom!!!"

A dark figure suddenly descended from the sky, crushing the remnants of Nightmare's flesh with a single stomp. With a playful expression, the figure looked down at Suzuki Seimei not far away.

Looking at the unexpected guest, Suzuki Harumi's expression also became somewhat serious.

The man-eating demon with short red hair and blue stripes covering its body is none other than Akaza, the Upper Moon Three of the Twelve Demon Moons.

"what?"

When Akaza saw Suzuki Seimei, he didn't rush to attack. Instead, he stared at him with his golden eyes, looking him up and down. The playful smile on his face gradually turned into surprise and curiosity.

Perhaps because Akaza was a martial artist in his previous life, he could tell the strength of a person's fighting spirit just by looking at them after he became a demon.

The so-called "battle spirit" is the manifestation of the strength of a person's qi and blood, as well as the fusion of spirit and will.

The stronger a person is, the stronger their fighting spirit will be.

From Akaza's perspective, Suzuki Seimei was like a giant furnace, the surrounding air distorted by the powerful fighting spirit he exuded.

Since Akaza was transformed into a demon, this was the first time he had ever seen a human who could exude such powerful fighting spirit, even comparable to Upper Moon One, Kokushibo.

It's important to know that Kokushibo is no ordinary Upper Moon demon; he is recognized as the strongest subordinate under Muzan Kibutsuji.

Back when he was still human, Kokushibo was already a "Pillar" level powerhouse in the Demon Slayer Corps, and one of the first Breathing Technique swordsmen.

Now, hundreds of years have passed, and Kokushibo's strength is even more unfathomable, firmly holding the top position among the Twelve Demon Moons.

Although Akaza is Upper Moon Three, in a real fight, his strength is no weaker than Upper Moon Two, Doma.

However, compared to Kokushibo, Akaza and Doma are still too weak. Even if the two of them joined forces, they might not be able to defeat Kokushibo.

Therefore, Akaza's surprise upon seeing that the fighting spirit emanating from the human child Suzuki Seimei was comparable to that of Kokushibo was understandable.

The reason why Suzuki Seimei's fighting spirit was comparable to that of an old demon like Kokushibo was mainly because he had stored up more than two hundred years of pure internal energy within his body.

"My name is Akaza!"

Akaza stared at Suzuki Haruaki for a while, then couldn't help but ask, "Kid, what's your name?"

"You better remember this: my name is Suzuki Haruaki, and I'm the one who will kill you!"

Thunder Breathing, First Form - Thunderclap Flash - Divine Speed!

"boom!!!"

The ground beneath Suzuki Seimei's feet shattered instantly, and his entire body crackled with dazzling golden lightning, bursting forth like a roaring thunder dragon. The Demon-Slaying Sword in his hand swept horizontally toward Akaza's neck.

Destruction Kill - Compass!

Sensing the undisguised killing intent emanating from Suzuki Seimei, Akaza's pupils constricted sharply, and a twelve-pointed snowflake array instantly appeared beneath his feet.

【Destruction Kill - Compass】is the core of Akaza's Blood Demon Art. Within the range of the Snowflake Array, he can sense the opponent's fighting spirit like a compass, making his own attacks and evasions as precise as if he were attracted by a magnet.

Therefore, the stronger the fighting spirit, the easier it is for the [Destruction Kill - Compass Needle] to capture it.

"Oh no—"

"Pfft!!!"

The moment Suzuki Seimei stepped into the range of [Destruction Kill: Compass], Akaza's expression changed drastically. He felt a chill on his neck, and his head was instantly lifted into the air.

While the power of 【Destruction Kill - Compass】 is very strong, it can only allow Akaza to more accurately capture the enemy's movement trajectory, but it cannot enhance his own speed.

To put it simply, Akaza used [Destruction Kill: Compass] to capture Suzuki Seimei's attack trajectory, but his body couldn't react in time!

Before he awakened the [Bull Body], Suzuki Seimei once used the "God Speed" technique to instantly kill the "Sound Pillar" with a single sword strike.

Now that Suzuki Seimei has awakened the "Bull Body," his muscle density has increased eightfold. The power he unleashes when using "Godspeed" is naturally something Akaza cannot withstand.

"Damn it! I'm not the strongest yet, I need to get even stronger..."

After Akaza's head was severed by Suzuki Seimei, it did not turn to ashes like a normal cannibal. Instead, it roared loudly with great energy.

Destruction Kill - Chaos Style!

Under Akaza's control, his headless demon body suddenly turned around, waving his arms, his hands transforming into blades that tore through the air, creating terrifying shockwaves as he blasted towards Suzuki Seimei's head.

Faced with the sudden attack from the headless demon, a look of surprise flashed in Suzuki Seimei's eyes, but he showed no intention of dodging. Instead, he took the initiative to swing his sword and meet the attack head-on.

"Pfft!!!"

Just as the headless demon's hand blade was about to strike Suzuki Seimei's head, his height suddenly shrank, allowing him to dodge the attack. He then took a step forward and severed both of its legs with a single sword strike.

???

Akaza was utterly astonished by Suzuki Seimei's outrageous actions.

If Akaza hadn't seen it with his own eyes, he would never have believed that Suzuki Seimei, a human, could shrink his body to avoid the headless demon's attacks.

"boom!!!"

Before Akaza could recover from his shock, Suzuki Seimei suddenly flew in front of his head and kicked it away.
