I ask you to write about monsters, but you write about Foundation files?

"Damn, it's really 055's file!".

"055 is also a Keter-class !!."

"Great!But what does this [unknown] mean??"

"Are you stupid? Containment-055 is an antimeme! If it's an antimeme, its message must be [unknown]!"

"I feel like these containments are getting bigger than I ever imagined!"

"I really love the Foundation!hahaha!"

"Containment-055's file, even though that Marion just said it, I'd like to see ......

file now."

"Is this containment-055 also an antimemetic monster?

"I feel that the concept of antimemes is a bit abstract, but it's also very attractive!"

"Brothers, don't guess, let's read carefully!"

「......」

Special Containment Procedures Below

This is the description of Containment-055......

[Description: Containment-055 is a "self-kept secret" or "antimemetic."] Information regarding Containment-055, such as its physical appearance, nature, behavior, and origin, is self-concealing.

For example:

"How Site-19 first acquired Containment-055 is unknown. 」

"It is unknown when and by whom Containment -055 was obtained. 」

"The physical appearance of Containment-055 is unknown, but it is not indescribable or invisible, and it is normal for one to enter Containment-055's chamber and observe it, even to write notes, even memorize them, make sketches, take photographs, and make audio or video recordings, and in fact there are a large number of such observations in the documents. However, upon such observation, information about the physical appearance of Containment-055 will be "leaked" out of their minds.

Despite the presence of researchers supervising these tests, personnel dispatched to describe Containment-055 will become delirious and lose interest in the mission.

Dispatched to sketch a photograph of Containment-055, but personnel were unable to remember what the photograph looked like.

Security personnel observing Containment-055 via CCTV cameras will experience exhaustion after their shift and will lose relevant memories of previous hours. 」

"It is unknown who authorized the construction of Containment-055's containment chamber, why it was constructed in this way, and the purpose of said containment procedures. 」

"Despite the ease of access to Containment-055's room, Site-19 personnel, when questioned, all stated that they were unaware of Containment-055's existence. 」

............

All of these cases, usually rediscovered periodically by the reader of the document, can cause severe panic, though this state of apprehension lasts at most a few minutes before being forgotten.

A large amount of scientific data on Containment-055 has been documented, but it cannot be studied.

There have been more than one attempt to destroy Containment-055 or move it from Site-19 to another site, but, for unknown reasons, all of them have failed.

Containment-055 may be extremely of a physical threat, and it may have killed hundreds of personnel, and we have no way of knowing.

It is clear that Containment-055 is a significant memetic threat, or psychic threat, and as such, it has been classified as Keter. 】

............

"I'll go, the nature of Containment-055 is too inexplicable, isn't it?!!"

"yes! I think this thing is scarier than the previous 096,173! Because you don't even know what this thing is!"

"Agreed!! although there is no written information on what 055 is in the file, I think this kind of unknown is the most terrifying!"

"It's an antimeme, you can't remember it, so how can you deal with it?"

"Damn, the monster theme of this work corresponds to Containment Item-055?"

"055 may have killed hundreds of people, but no one knows, tsk, it's terrible!"

"The more this happens, the more curious I am, what the hell is it......

."

「......」

Later in the description,

is an additional document:

[An analysis of Containment-055:

The author of the document believes that Containment-055 was never officially acquired by "DATA EXPUNGED", and in fact, it was an independent or remotely controlled spy who had been placed at Site-19 by an unknown third party for one or all of the following purposes:

"Silently observe or interfere with Site-19's activities."

"Silently observing or interfering with the activities of other containment sites".

"Silently observing or interfering with the activities of the human world".

"Silently observing or interfering with other containment objects".

"Silently observe or interfere with [DATA EXPUNGED]".

No action has been proposed to address these potential threats, or is theoretically feasible ......].

............

After analyzing the document.

There is another appendix,

It seems to be a person's message:

[Hey, if this thing is really an "antimeme", then why can't it be that it's an "antimeme" that has been eliminated? We must be wrong about it...... Wait, what would happen if we kept keeping track of what it wasn't? Would we remember those things?

—Bart].

............

After this appendix,

There is also an additional document,

This document is a copy of the personnel mission report after the Foundation organized an investigation team and entered Containment Chamber 055 to investigate:

[Dr. Foundation: Alright, now I'm going to ask you some questions about 55.]

Mission: How many?

Dr. Foundation: Containment-055, you just investigated.

Mission: Sorry, I don't know what you're talking about...... We have Containment-055?

Dr. Foundation: Okay...... So, what did you do in the last two hours?

Mission: Huh......? I don't know anything. (Subject appears uncomfortable).

Dr. Foundation: Hmm...... So, do you remember that we all agreed that it wasn't spherical?

Mission: What is not...... Ahh

Dr. Foundation: Do you remember?

Mission: Hmm...... yes, I would like to say that I don't know what it is, but I know there's a ...... there. Well, there's something you can't remember, and it's not a sphere.

Dr. Foundation: Wait, what are you saying it's not a sphere?

Task Personnel: Containment-055.

Dr. Foundation: What?

Officer: Doctor, do you remember agreeing that there was something that wasn't round?

Dr. Foundation: Ah...... Yes ......].

............

At the end of the archive,

is an analysis ...... the mission report

[From this interview, it can be shown that one can remember that Containment-055 is not, i.e., a denial of facts, and that we may be able to infer its existence from these memories repeatedly.]

Personnel involved in this investigation eventually reported moderate levels of disorientation and psychological trauma, both of which were related to repeated recall and forgetfulness of Containment-055.

However, no long-term behavioral or health problems were observed, and psychological evaluations of investigators showed that the mental distress would slowly disappear over time.

Recommendation: At least one personnel at each critical site who can remember the presence of Containment-055 is to be staffed. 】
