In this crossover anime, I fight against the supernatural in my everyday world.

He thought to himself that although he didn't know the true identity of the "masked" person, he was, after all, an excellent criminal investigation chief whom the other party had personally acknowledged, and also an assistant recognized by the other party.

Fight alongside the heroes who secretly protect Kyoto City.

This allowed Soichiro Yagami to rediscover the same exhilarating excitement and sense of responsibility he felt when he first became a detective.

"so..."

Souichirou Yagami patted Yosei on the shoulder, his expression softening slightly, and smiled.

“Some things, even if they don’t follow legal procedures, but think about those who were saved, including the girl next to you and her sister. Don’t you think ‘Masked’ is a true hero?”

Yohoshi seemed to have been persuaded by Yagami Soichiro, and nodded very sincerely.

"Yes, the hero who secretly protects Kyoto is so cool. Even if he started a harem, I'm sure everyone would understand."

"You little brat, don't talk nonsense."

.......

After Yoru left, Yagami Souichirou looked at the other's back, shook his head with a wry smile, and thought to himself that this kid was about the same age as his son, also a first-year high school student, but the feeling he gave off was completely different.

Soichiro Yagami had a feeling.

Although his son, Light Yagami, was perfect in every way, as a father, he always had a feeling that his son was hiding something.

What could be so important that even the head of the Metropolitan Police Department's Criminal Investigation Bureau, the father whom his son admires and aspires to be the most, has to keep it a secret?

Soichiro Yagami shook his head, and just as he was about to continue investigating the scene, the faces of the sisters, Saki Kawasaki and Kyoka Kawasaki, suddenly appeared in his mind.

"Wait a minute...who are those two sisters...?"

Souichirou Yagami frowned slightly and waved to one of his subordinates not far away.

"Show me the list of passengers trapped on the Ferris wheel."

"Oh, alright."

After receiving the list, Soichiro Yagami scanned it and, sure enough, saw a very familiar name.

"Kawasaki Saki..."

Upon seeing that familiar name, combined with Kawasaki Saki's light blue high ponytail and outstanding appearance, Yagami Souichirou finally remembered where he had seen her before.

When the Kyoto train malfunctioned, this girl and her sister were among the passengers trapped on board.

This time, he's involved in another attack at an amusement park?

Moreover, was "Masked" involved in both instances?

Is this really just a coincidence?

Or...

What kind of private connection do these sisters have with that "masked" man?

even...

Is Saki Kawasaki the "Masked"?

Thinking of this, Soichiro Yagami forcibly interrupted his thoughts, unwilling to continue pondering.

At first, he really wanted to catch "Mask".

After all, the other party was the most difficult and unpredictable criminal he had ever dealt with in his criminal investigation career.

But now, Soichiro Yagami's attitude is different.

Rather than believing the perpetrator, he preferred to believe that "Masked" was someone with special abilities who was unwilling to be bound by the existing legal system, and therefore chose to protect Kyoto City in secret through this method. He was a maverick who pursued justice.

Moreover, he himself is also an accomplice of "Mask".

Given this situation, why bother investigating their true identity?

Sacrificing oneself for the greater good?

Although Soichiro Yagami is rather rigid and stubborn, he is not the kind of person who is inflexible.

Since "Mask" is doing good things, even if his style is radical, as the head of the criminal investigation department, he still has to condemn him as a criminal on the surface.

As for what happens in private?

Just say you can't trace it. If anyone thinks they can, then go ahead and trace it, just don't come looking for me.

........

On the other hand, after leaving the amusement park, Ye Xing did not go straight home.

To Soichiro Yagami and the Metropolitan Police Department members, the explosion site was a charred, bloody mess. The body parts and blood, roasted by the high temperature, emitted a nauseating stench, leaving behind few clues worth investigating.

But in Ye Xing's eyes, it was completely different.

From the location where the ex-convicts who drove the truck died, all the way to the entrance of the amusement park, there is a very obvious black, viscous trail.

A collective, sudden onset of mental instability?

This was entirely the work of an evil spirit.

Like a seasoned hunter, Night Star concealed his presence and followed the sticky black trail on the ground, heading towards a certain direction outside the amusement park.

Amusement parks with large areas like these are usually built in relatively remote, sparsely populated places due to land prices.

After walking for about ten minutes, Ye Xing could see that the black marks on the ground not only did not fade, but became more and more viscous and were even wriggling.

"So this is the place..."

He looked up and saw a small building in front of him, which he didn't know was originally used for but was now abandoned; it resembled a school building.

Judging from the dilapidated walls, the length of the weeds on the ground, and the casually open iron gate in front of it, this place has been abandoned for at least a decade.

The sky was no longer clear as before; instead, it was covered with dark clouds, and the air was slightly chilly, as if a downpour was about to begin at any moment.

The weather in Sakura Province has been so unpredictable these past few months, which doesn't seem to have much to do with this evil spirit.

"boom!"

Before the rain even started, a blinding flash of light suddenly appeared in the dark clouds.

Amidst a deafening roar of thunder, light illuminated the dilapidated building.

What came into Ye Xing's view was a terrifying face pasted on a window on the third floor of the building. The face was twisted into a grimace, and the eyes were filled with resentment as it stared intently at him.

Faced with this sudden gaze, Ye Xing was taken aback for a moment, then chuckled and shook her head.

"You're crazy. You made me laugh."

Immediately afterwards, his figure vanished from the spot.

The evil spirit behind the third-floor window was stunned by what it saw.

no...

What about people?

Where did that human go?

This evil spirit is now in its most twisted and malevolent stage.

It finally managed to select a few individuals with twisted desires who could be manipulated by it, and devised a perfect method to drive a large truck into densely populated areas, causing mass human deaths to satisfy its malice and bloodlust.

did not expect...

It actually failed.

Of course, although the evil spirit harbored intense resentment, it wouldn't dare to seek out the "mask" and seek revenge, even if it had a thousand lives.

Whether it was the other party or the black and white headless monster, in its perception, they were both powerful evil spirits that it absolutely could not contend with.

Having fled all the way here, it had accumulated intense resentment and a bloodlust. It had finally encountered a reckless human who dared to step into this area and seemed to be able to see it. It was ready to feast on him.

First, it appears in the other party's field of vision.

Then, in the next second, he appeared directly behind the male human and asked in a terrifying, hoarse voice, word by word.

"Can you...see me?"

This was the evil spirit's original plan.

But it never expected that the human would disappear after only the first step.

What's the situation?

at this time.

Out of the corner of his eye, the evil spirit saw a patch of darkness appear beside him.

Immediately following was a question uttered with a smile.

"You...can you see me?"

The evil spirit stiffly turned its head and saw a mysterious person wearing a black mask, exuding an aura that filled it with immense fear, standing there silently.

Above the mask was a white smiling pattern, which looked even more eerie in the dimly lit corridor.

"you you..."

"Oh?"

Hearing the words uttered by the evil spirit, Ye Xing was somewhat surprised.

"You can talk? This little thing is interesting."

Faced with Night Star's question, the evil spirit did not hesitate at all, making a choice driven by its survival instinct without any hesitation.

Turn around and run away.

Only then did Night Star finally see the full form of this evil spirit.

Its body is similar to that of a normal human, and its height is around 1.7 meters.

He had long, gray-white hair, and wore black shackles on his wrists and ankles.

"Shackles... evil spirits born from the negative impression of prison...?"

According to Rio Futaba and Miko Yotsuya's summary, the influence that evil spirits can have on humans, to a certain extent, also represents the power of the evil spirits themselves.

The first tier naturally consists of powerful evil spirits that can pull humans into the underworld, have a "gate" fused within them, and directly harm humans.

For example, the "trolley", the "flying head" in the unfinished building, and the ten-meter-tall giant evil spirit all belong to this category.
