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

The original plan was for Ye Xing to conceal his presence, search for the "door" in the hotel, or the evil spirit that had merged with the "door," and then remove it directly.

However, things took an unexpected turn when, immediately after he entered the hotel, the entire area merged with the underworld, transforming into a ghostly realm where evil spirits could roam freely.

Rio Futaba, Mai Sakurajima, Miko Yotsuya, and even Yohoshi herself believed that the evil spirit lurking in the hotel had a very keen sense of perception and had sensed their entry, which was why they took such measures.

Now it seems that this is not the case at all.

This strange incident did not involve the three "doors" being dangerous.

Instead, there are four doors.

However, before the members of the Xyz Society could act, an evil spirit that had merged with the "Gate" encountered a Killing Demon while traveling in the Otherworld and was then eaten.

The evil spirits' sudden actions in the hotel were entirely due to their sense of being hunted, prompting them to urgently increase their power as a form of self-preservation.

"but..."

Rio Futaba looked at the Demon of Slaughter standing there, seemingly lost in thought.

"Mr. Killer Ghost was able to defeat an evil spirit that had fused with the 'Gate' without even fusing with it himself. He is truly an extremely special existence."

At this point, Rio Futaba looked hesitant and glanced at Yohoshi beside her.

The latter immediately understood that she wanted to say something, but was also worried about what she didn't say.

"Little Killer..."

Night Star patted Killer Ghost on the shoulder and said in a serious tone.

"Actually, you are not a killing demon, but a spirit from the underworld formed from people's impressions of the legend of the killing demon."

When he said those words, Mai Sakurajima, Rio Futaba, and Miko Yotsuya all held their breath, waiting for the Demon of Slaughter's reaction.

You should know that when the Eight-Foot Man first heard that he was not actually eight feet tall, but rather a composite of people's impressions, he almost developed a mental illness.

Now, how will the Killer Demon react?

"Oh, that's how it is."

The Killer Ghost nodded noncommittally, seemingly having absolutely no interest in the matter.

"It doesn't matter how I came to be. What matters is that I only want to kill more evil spirits, and I will never stop."

"As long as I continue this kind of action, I will be a true demon of slaughter."

Upon hearing this, Ye Xing exclaimed in amazement.

"Wow, Little Killer, you're a philosopher too? What you said makes a lot of sense."

The demon's long hair cascaded down his cheeks as he gazed at the dimly lit street. His single remaining eye revealed a complex emotion, as if contemplating life... a kind of spiritual contemplation, as he murmured to himself.

"Perhaps, after I have eliminated all the evil spirits in this world, I will be able to touch true freedom."

"Your words sound a bit like those of an old friend of mine."

"It was just something I said offhand."

At this point, Ye Xing suddenly stopped smiling and slowly spoke to the Killing Demon.

"However, there is one thing I need your help with."

"speak."

"From now on, you'll stay in Tokyo and hunt evil spirits."

"You still need to tell me?"

As if a sore spot had been touched, the killing demon's already terrifying face became even more grotesque.

"In the underworld of Kyoto City, I can hardly find any powerful evil spirits left!"

"Do you know how long it took me to walk from Kyoto to Tokyo?!"

"Please, I'm begging you, leave me a few, please don't kill them!"

The killer seemed to be on the verge of tears by the end.

As the Grim Reaper among monsters, its lust for evil spirits never dissipates; only by tearing apart and devouring powerful evil spirits with its own hands can it find some relief.

As a result of Ye Xing's actions in the Kyoto underworld, those powerful evil spirits were either eaten by Ye Xing or went into hiding.

The remaining portion passed through the "door" into the real world.

The killing demon couldn't hold on any longer.

Tormented by its inner bloodlust, it could only travel on foot, traversing the thick, sticky black fog, all the way from Kyoto to Tokyo.

Unexpectedly, after only a few days in Tokyo and having just had a great time killing people, I ran into this guy again.

The killing demon is so frustrated.

"Don't worry, don't worry."

Night Star smiled and comforted her.

"We won't stay in Tokyo for long. What's yours is all yours."

The killer wiped away the tears from beside his only remaining eye, looking extremely aggrieved.

"Really?"

"Really, don't worry."

"That's great."

Seeing the childlike, innocent smile on the face of the Killer Demon, Rio Futaba and the others had complicated expressions, unsure of how to react.

abstract...

Has the phenomenon of ghost stories already begun to emerge?

........

Meanwhile, in the Tokyo Metropolitan Police Department's operations conference room.

"L, the news from the scene has come back."

L, who was squatting on the chair, turned his head and said calmly.

"Kira escaped?"

Upon hearing this, the high-ranking officer from the Metropolitan Police Department looked embarrassed and sighed.

"Yes, and Mikazuki Munechika as well..."

"It's just a meaningless old relic, no need to mention it."

L doesn't care at all about the Five Great Swords of the World or the legendary swords of the Cherry Blossom Province.

In his view, Mikazuki Munechika was just an ordinary iron sword with no value whatsoever.

How many police officers died?

Upon hearing this question, a senior official from the Metropolitan Police Department displayed a complex expression and slowly replied.

"Although some officers were injured, none of them were serious...no one died."

"Ok?"

L raised an eyebrow, his eyes flashing, and after a few seconds, he said meaningfully.

"No one died? That's not good news."

"No one died, how can that not be good news?"

L tapped his fingers on the table and said calmly.

"He managed to escape unscathed even within the encirclement of your Metropolitan Police Department, which proves that he possesses special abilities that are unimaginable to ordinary people. He could kill some of the police officers, or even all of them."

"But if he really does that, it means that no matter what Kira's true identity is, he is just a criminal who acts recklessly."

"In this incident, Kira didn't kill a single police officer, which means he's no ordinary criminal."

"Based on his actions during this period and the cases he has committed, it proves that this guy has his own set of rules for doing things."

"The principle of punishing only the wicked."

At this point, L paused for a moment, seemingly lost in thought.

"But why... when he could have left the scene much earlier, did he choose to stall for time with the Metropolitan Police Department...? Was it absolute confidence in his own abilities? Or was he enjoying the thrill? It's probably more than that..."

A glint of light flashed in L's eyes as he turned his chair and looked at the high-ranking officer from the Metropolitan Police Department.

"I hope your Metropolitan Police Department can put together a report by tomorrow morning."

"To compile a list of all the unusual events that occurred in Tokyo between the intrusion into the Tokyo National Museum and Kira's escape from the scene."

“I need to see every detail in the report.”

190 Hiratsuka Shizuka joins the battle, shocking the Empress.

An hour later, inside a hotel two kilometers away from Shibuya Shopping Street.

"Seriously, there were so many terrifying monsters back then!"

"Yes, they can climb up the hotel walls and squeeze through the cracks in the doors. Many of them don't look like humans at all!"

"I've seen one that could stretch its neck very long, about seven or eight meters long!"

.......

The police officers dispatched by the Tokyo Metropolitan Police Department listened to the guests' absurd and contradictory descriptions with expressions of skepticism.

"But...we've checked the security footage, and there wasn't any monster...and what about that thing you mentioned..."

Before the police officer could finish speaking, the guests who had narrowly escaped death began to speak again.

"Yes, that woman in black mourning clothes!"

"If it weren't for her, we wouldn't have been saved at all today!"

"An Onmyoji, definitely a very powerful Onmyoji!"

A monster with a long neck and a terrifying face?

A woman dressed in black mourning clothes, looking like an Onmyoji (yin-yang master).
