When the international long-distance call from Chuuya Nakahara came, Dazai Osamu was confused. Although he had a history of playing tricks on his friends, this time was obviously not in his plan. After all, when he was recently robbing the Hong Kong underworld, he was using the name of Mori Ogai.

Dazai Osamu never thought that someone would dare to use his name to provoke Nakahara Chuuya. The description of him as the ceiling of combat power and the black mud spirit in the world is not just a joke.

Moreover, this happened right under his nose, in such an open and aboveboard manner, which was simply not taking him seriously.

After mocking Chuuya's slug-like thinking over the phone, Dazai Osamu set out to investigate who dared to be so arrogant. It made sense for people who knew that he and Chuuya Nakahara were once partners to not recognize him. And there were not many people who dared to do such a thing even though they knew who he was.

So rather than something as trivial as anger, Dazai Osamu was more curious - experiencing new things has always been one of the things he pursues.

And with his ability, it was too easy to find someone when the other party was hardly trying to hide it.

It was precisely because it was so easy that Dazai Osamu was more alert. He dared to use Chuuya's name to bully the port mafia and then openly blamed him. This is not something that ordinary people can do.

Anyone with a little common sense, or a little brain, would not do this. And since he did this, he must have something to rely on.

Either he was deliberately lured to find someone, or he was deliberately provoked - anyway, for Dazai Osamu, these two things meant the same result.

He did not believe that the person who could do such a thing was a complete idiot. He was more inclined to analyze these behaviors seriously.

Of course, this thought wavered for a moment when he saw the life-size pillow nestled in the corner of the closet.

But the next moment, after analyzing his brain, Dazai Osamu came up with at least sixteen sources of the two types of photos, front and back, and dozens of possible uses.

He was thinking whether he had done anything inappropriate recently.

This made Dazai Osamu more determined to investigate this person's heart - he certainly noticed the little trick at the door, and the fact that a pencil refill could be stuck under the crack of the door also showed that the owner of this room was somewhat vigilant.

But whether this vigilance is real or fake, whether it is deliberately shown to him, or whether it is a test, needs to be discussed further.

Dazai Osamu put the lead back in place anyway. But he didn't adjust the direction of the soft hair that was pressed out after he stepped on the soft cushion at the door. Didn't the other party always want to test and provoke him? So he left a little clue for the other party, and there was nothing wrong with provoking the other party.

He turned out all the things in the cupboard. The choker and vest were all styles that Chuuya would wear, but the focus was still on the pillow.

Dazai Osamu never remembered having a photo like this before, and it was the kind where he took the photo while looking at the camera - but looking at the details, it really looked like him.

Moreover, although he was somewhat reluctant to admit it, he was able to perform the movements in the video.

Dazai Osamu touched the pillow and suddenly felt that there was not only cotton inside, but also a hard spot.

There's something in here - he ran his fingers along the edge and found the zipper. When he opened it, it was like opening the door to a new world.

Dazai Osamu regretted opening this Pandora's box for a moment.

If anyone thinks this pillow is "unsightly", then they should really take a look at the book hidden inside the pillow - the cover itself is eye-catching enough.

He and Chuuya - even Dazai Osamu felt a moment of shame. Who took this video?

No, he and Chuuya never had such a relationship, and now he wanted to know who "created" this thing.

Dazai Osamu sat on the bed and opened the book.

Maybe it felt a little strange at first, but after reading it more, Dazai Osamu felt more and more that this was not a simple photo album. The stories inside were extremely suggestive, and even went straight to the point of the changes that "Arabato" would bring to safety devices.

Dazai Osamu stroked the footer of the page. The content inside was no longer important. What was important was what the content implicitly conveyed - "Arahatsu", or "Fighting Arahatsu" would not only be restricted by safety devices, but would also restrict safety devices and even change them.

The two different names, "Arabatu" and "Fighting Arabatu", actually symbolize two different states of the artifact. The appearance of the latter is quite dangerous. Dazai Osamu looked at the state of the "gun" expressed in a more explicit way. In fact, it should be another way to replace the entity of "Fighting Arabatu". The different states of the characters in this book also represent the consequences of different states of the artifact.

Obviously, if a certain element represented by Dazai Osamu - of course Dazai Osamu himself has not yet extracted this element, this book only implicitly expresses this element as "that liquid", when this element is combined with a certain characteristic of Chuuya Nakahara's "Fighting Arakawa Hospit", it is very likely to cause some special changes in Chuuya himself - just like what is shown in the photo, Chuuya's sullen expression implies some kind of painful consequence.

But if in some special circumstances, Chuuya has entered a "distracted" state as shown in the photo, then the way to remedy it should be to use something in him to achieve a deeper and final fusion with Chuuya.

Perhaps this element is "disqualification from being human", but Dazai Osamu needs further verification.

As for the last part about having a child, Dazai Osamu felt that this was more like a hint of a conceptual "inheritance".

He knew a lot about Nakahara Chuuya. The Special Ability Division had once created a file specifically for him, and Dazai Osamu had read this file.

And every time it is used in a "dirty" way, it will cause visible damage to the body. From this perspective, this "birth" should actually symbolize a new safety device.

Beyond that, there are many ways to speculate about the origin of this new security device.

Dazai Osamu thought about the past quickly and decided to watch it again to see if he could find any new clues.

You ask him why he doesn't consider the more negative aspects?

Isn't this a very simple truth? At the beginning, "someone" provoked him in an extremely explicit way, which originally carried the concept of "explicit", and also wanted to lure him in and show him these things. Of course, he has never done such a thing, but the photo above is so real, so real that it is irrefutable. That means that this incident either happened in another time and space - but Dazai Osamu is sure that even if there is a world where he and Chuuya have such a relationship, he will definitely not take pictures of the whole process, and add text.

There is only one explanation for this, some information cannot be presented in the most intuitive way, just like some words cannot be said clearly.

At the same time, the above situation further illustrates the reality of the situation and its future severity.

At this moment, the lock outside made a low sound, followed by the obvious sound of the door opening.

It seems that someone has come back. Dazai Osamu turned the page again because he also wanted to see who this person is.

When he actually saw him, although Dazai Osamu did not show it on the surface, he was shocked in his heart.

This face, which was exactly the same as Nakahara Chuuya's, almost instantly verified some of his guesses. At the same time, it also made Dazai Osamu sure that it was definitely not an accident that he entered this room and turned to this book.

The person in front of me definitely does not show this kind of simplicity.

This man looked a little embarrassed, but one had to admit that he really felt a lot like Chuuya, who had just been dragged out of the laboratory by Randou.

Although Dazai Osamu had never actually seen Chuuya like that, he could imagine it.

Dazai Osamu began to get him to talk, and after a few rounds he easily figured out a lot of things.

He didn't seem to care much about Dazai Osamu's appearance, and he was able to remain calm even when he was ignored, which shows that he either often experiences such things, or has a mind that doesn't match his appearance. He knows that Dazai Osamu is the so-called "traitor", is familiar with everything about the "Port Mafia", and has a strange feeling for the real "Nakahara Chuuya", because when Dazai Osamu could emphasize Chuuya's height, this person showed some different emotions.

Then, he heard the man call out "Daddy" without hesitation.

——Let’s call him a “suspected safety device” for now.

Dazai Osamu thought about this title, it is the role of "father" rather than "mother", and it is the same angle in this album. Why is that?

"Mother" usually refers to a role of nurturing, while father is a role that provides something key to the mother. Dazai Osamu looked at this "suspicious safety device" and his first reaction was that he, like Chuuya, came from some kind of experiment.

And it was an experiment based on Chuuya. The question is, what does he provide as a "father"?

The answer soon came to him.

The moment the two touched, Dazai felt an electric current running through him. He looked at his fingers. He had felt this feeling before, on Odasaku's body that evening, and in the thick fog in Yokohama not long ago.

This is a peculiarity, and it is a peculiarity that is related to oneself.

He now confirms that "disqualification from being human" is the most important thing he can provide as a "father".

Then, Dazai Osamu found an opportunity to subdue him - it was strange, looking at the muscle lines of this "suspected safety device" and the feeling he gave, his physical skills should be better than his, so how could he be subdued so easily?

Is there something you want to tell him?

He can’t say it clearly, or maybe he is not even aware of it?

Dazai Osamu deliberately touched his waist. Chuuya Nakahara is a man with a very strong body, but few people know that Chuuya Nakahara's waist is very sensitive.

When he was still in the Hong Kong underworld, Dazai often used this to embarrass Chuuya.

However, Chuuya's sudden appearance did indeed startle Dazai Osamu, especially when he maintained this action.

Fortunately, this matter is related to Zhong Ye, and he can explain -

“Hmm——”

The suspected device under him suddenly made an indescribable sound. From Dazai Osamu's perspective, the man looked aggrieved with tears in the corners of his eyes. He didn't look like Chuuya at all.

This is clearly another living self.

At this moment, a somewhat absurd, yet seemingly extremely reasonable idea appeared in Dazai Osamu's mind.

He sat down patiently and listened to his "confession" under Chuuya's coercion.

Dazai Osamu naturally knew that he would not tell the complete truth, but it was also impossible for him to tell a complete lie.

When Dazai Osamu heard this person say that he "brought these things when he was cleaning Dazai Osamu's room", he became more certain that the person who really wanted to convey the message in such an extreme way might not be the "suspected security device" in front of him, but the other self standing behind him and pushing him into this world.

People from another world are extremely dangerous. There is no possibility of communication between the worlds, otherwise there will be unpredictable consequences.

Now that there is this exception, the first thing to consider is the objective consequences brought about by this exception, which is even secondary to his identity - after all, this person's purpose will only cause subsequent subjective consequences.

Fortunately, Nakahara Chuuya had already understood something similar when he noticed the peculiarities. The next thing was a natural progression, and before figuring out everything, it was best not to let this "suspected security device" show up in front of other people.

For this reason, it was natural that Nakahara Chuuya took the blame for Hongye Sister's misunderstanding of the double black.

Dazai Osamu was not surprised that Chuuya would get furious after seeing the picture album. After all, it was a little slug - it was hard for him to see the meaning behind that thing. He had already memorized all the contents inside. Even if Chuuya did not take action, he would still destroy it.

Regardless of what it means, he doesn't want to have anything to do with Chuuya, especially in this way.

The contents inside must not be known by a fourth person—at least not in this world.

Chuuya's side would be a better place to accommodate this visitor from another world, Dazai Osamu thought, and he put the bandage that Chuuya had roughly pulled off back on bit by bit.

The bed inside was in a mess, and the jacket and choker that were "suspected to be safety devices" were not taken.

He looked closely at the windbreaker, which was the same as his. The coat was actually very large, and the size didn't seem to be suitable for a "suspected safety device". It was probably someone else's - after all, no one needs to buy large-sized clothes specifically, right? Is it just to look cool?

He was probably wearing the clothes of Dazai Osamu from another world. Was he also a member of the Armed Detective Agency in that world? That was impossible. He had just clearly stated that Dazai Osamu was the "leader" of another world.

This dress...

Dazai Osamu examined him, but soon his expression changed.

There seemed to be a small tear in the inner pocket of the clothes, but it was sewn up - this is not a big deal, but the way the thread on the inner layer is sewn up feels so much like the special method that Oda Sakunosuke used to sew his own clothes.

Maybe it's a stretch to say that a mafia member would mend clothes, but Oda Sakunosuke had to raise several children at the time, so he always lived a simple life. If the damage to his coat or windbreaker was not too serious, he would sew it himself.

At that time, Dazai and Ango even teased him about this. Odasaku was not very good at sewing clothes, so the threads were always messy, but Dazai would not keep clothes with holes unless the clothes had special meaning.

In other words, is it possible that Odasaku in another world is still alive?
