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

If I were to take this notebook now and come into contact with the truth of this world, I myself...

Is it possible to turn back?

After hesitating for a long time, Yotsuya Miko finally extended her fair right hand, her slender fingers resting on the cover of the black notebook, and took it.

She took a deep breath, calming the tension in her chest, and slowly opened it.

The first sentence that caught her eye stunned Yotsuya Miko.

March 20th, Weather: Cloudy.

Today, I awakened the ability to see evil spirits and ghosts.

[By the way, I woke up this morning and saw a grotesque monster standing next to my bed. It really scared me.]

Upon seeing this sentence, Yotsuya Miko couldn't help but sigh.

I can only say I empathize with them.

Even now, she still breaks out in a cold sweat when she occasionally wakes up in the morning and is suddenly startled by evil spirits and ghosts.

At the same time, Yotsuya Miko's heart, which had been hanging in suspense, was finally able to relax a little.

She glanced at Ye Xing, who was leaning against the rooftop railing, gazing at the distant scenery. She thought to herself that although he seemed very calm, he must have been just as frightened as she was when he first encountered the evil spirit.

Having fear is what makes a normal human being.

Yotsuya Miko just managed a slight smile, but when she saw what followed, her smile froze.

[I've finished eating.]

Surprisingly, evil spirits actually taste pretty good. How should I describe it?

The texture is somewhat like spicy strips, but the outer shell is crispy.

[As those who frequently consume evil spirits know, swallowing them is easy, but cooking them is difficult.]

I tried frying it in oil, but it doesn't seem to count as food; it can only be eaten raw.

[Well, let's just eat it raw. It has a raw, natural flavor.]

Miko Yotsuya's brain had crashed; she couldn't even think, and simply turned a page unconsciously.

March 26, Weather: Sunny.

After consuming evil spirits these past few days, I have gained a deeper understanding of my own abilities.

[It's not just about seeing evil spirits.]

[After consuming it, my physical attributes will be slightly enhanced; the specific effect seems to depend on the strength of the target evil spirit.]

Furthermore, after consuming it, fragments of memories that don't belong to me appear in my mind.

I speculate that this might be some of the evil spirit's experiences during its previous life.

In these fragmented memories, I merely act as a third party with an omniscient perspective; I don't experience them firsthand, so they have no impact on me personally.

...

[April 2nd, Weather: Clear, sunny sky with no clouds.]

How many evil spirits have I consumed during this time? I haven't made a point of keeping track.

[Around two or three hundred? Maybe four or five hundred, after all, there are just too many of these things.]

As I devoured more and more evil spirits, I discovered that ordinary evil spirits and ghosts, perhaps out of fear of their natural enemies, no longer dared to approach me.

[They even flee quickly after I appear.]

Upon seeing this record, Miko Yotsuya's eyebrows twitched twice.

From March 20th to April 2nd, it was a total of thirteen days.

How could Night Star have devoured hundreds of evil spirits in such a short time?

That means he eats at least twenty or thirty of them every day?

Although it wasn't explicitly stated in the notebook, based on Yotsuya Miko's experience, unless she deliberately went to such remote and dark places, she would only see about four or five of those "things" each day.

what does this mean?

This means that ever since Ye Xing awakened his Yin-Yang eyes, he has never avoided evil spirits. On the contrary, he actively seeks out evil spirits every day.

Can this person be considered normal?!

The next entry contained content that Yotsuya Miko found difficult to understand.

[April 4th, Weather: Cloudy and rainy.]

Another "door" has been found.

Just as I suspected, in areas where this thing exists, evil spirits and ghosts within a radius of several kilometers become much more active.

If this is ignored, Kyoto City will become a place where a hundred demons roam at night in less than two months, won't it?

[Those old folks at the shrine, none of them are very capable. The evil spirit is clinging to their backs, and they're saying they'll consecrate my shrine and pray to the gods?]

However, if the setting for evil spirits and ghosts is the same as in Yotsuya Miko's world, I remember there are so-called gods who possess the ability to eliminate evil spirits.

Perhaps I just didn't find the right place.

Or perhaps, the gods truly exist, but they simply choose not to help me.

It doesn't matter which one it is anymore.

Tomorrow is the first day of school at Soubu High School. Let's consider our next steps after we've met Yotsuya Miko.

That concludes the daily entries in the notebook.

At the very end, Ye Xing compiled a list of the reactions that occurred when using weapons of various materials to attack evil spirits.

Upon reading this passage, Yotsuya Miko finally understood why the other party had done that thing that morning.

It's not for pleasure.

Instead, they were conducting experiments to find out which material of weaponry could inflict the greatest damage on evil spirits.

What is professionalism?

That's what you call professional.

Miko Yotsuya even felt that it had a touch of scientific exorcism.

There was one thing, however, that she couldn't understand.

Yotsuya Miko looked up at Yoruhoshi and asked in confusion.

"What do you mean by 'my world'? Have you seen me before? And what is this so-called 'door'?"

"Hmm... how should I describe it?"

Ye Xing shrugged and laughed nonchalantly.

You can understand it as, "Although I've never met you, I know you very well."

As for the door...

"If you have time after school today, I can show you in person. Once you see it, you'll understand everything."

006 The Evil Spirit of Entrapment

When Yohoshi returned to the classroom, she saw Touma Kazusa place a can of drink on her desk.

Caught red-handed, Touma Kazusa remained completely calm, speaking in her usual emotionless and indifferent tone.

"I don't like owing favors to others."

Ye Xing walked slowly to the table, looked at the can of drink on the table, and shook her head with a complicated expression.

"You, Touma Kazusa, I did help you out, and you repay kindness with enmity by making me drink Pepsi toilet cleaner."

Immediately afterwards, Ye Xing stretched out his right hand and placed it on the can of Pepsi. He was so shocked that his pupils shrank, as if he had seen something unbelievable.

"And it's at room temperature!"

"Forehead..."

Touma Kazusa had anticipated many scenarios, such as Yosei misunderstanding her meaning and then starting to pester her relentlessly.

Or perhaps the other party simply doesn't accept it.

Even if Yosei threw the drink into the trash can right in front of her, Touma Kazusa wouldn't be surprised, after all, the two of them had just had an argument that morning.

This is the only situation she truly did not anticipate.

"Room temperature...is there a problem?"

Upon hearing Touma Kazusa's question, Yosei replied in a matter-of-fact tone, as if it were the simplest elementary school question.

Do you know what cola is also called?

"do not know."

"The ultimate comfort drink for couch potatoes".

Ye Xing picked up the can of Pepsi, and in his beautiful black pupils, he seemed to be reflecting on the vicissitudes of life, like an old man standing in the sunset.

"Even toilet cleaner, if it's frozen, might have a unique charm in this early spring season, paired with the beautiful cherry blossoms falling outside the window."

"But if I may be frank, the fact that the soda wasn't chilled is just a facade for the defense."

Touma Kazusa's two delicate eyebrows twitched slightly. After a long silence, she finally said in a low voice.

"In short, I've repaid the favor I owed you."

After saying that, she lay back down on her desk and went back to sleep.

"Those two people are really strange, aren't they?"

"He's not just a little bit weird, he's downright eccentric."

"Shh, keep your voice down, don't let that guy hear you. He's a dangerous guy who always carries a revolver."

Hearing the students whispering in the distance, Ye Xing rolled her eyes.

Goodness, this is getting more and more outrageous.
