CLR Event

File number: NC_CLREVENT


"Sorry to disturb you, sir, but I think you'll be interested in this."

"Several weeks ago, the email which IOP sent us about Neural Clouds was tampered with. One of our Commanders discovered the problem; the person who intercepted the mail inserted a hidden message on the left side of the document in what looked like an ordinary punch-hole. When decrypted, it returned: CLR-Event."

"At first, I had no idea what it was and after encrypting the original email I didn't pursue it any further after putting it into Griffin's secret file storage. However, two days ago, I unexpectedly encountered this sound clip again. You might want to hear it."

"I believe that two years ago, 42Lab's "Neural Cloud" project wasn't as successful as we took it to be. They seem to be hiding something, but we don't need to be too worried. IOP's helped us look into the safety of "Neural Cloud" technology, and it won't affect our operations. Now is also a time when we need their technical assistance, so I feel that interfering with it will do us no good."

"I will save this audio clip into the encrypted file database as well. If need be, it might become a bargaining chip for negotiations with them - of course, I sincerely hope that our cooperation with them can be carried out happily and smoothly. If you feel the matter merits further investigation, I am at your disposal."

An audio file was posted along with the message:



Audio transcript as follows: 

“My apologies for intercepting your mail. I have no choice. They hide everything. Someone sacrificed life. Doll's memories are erased. And we are not allowed to say anything. There is a conspiracy of NC test. The keyword is CLR Event. Please find the truth and save all of us.”

At the end of the message, a series of beeps play. This is not morse code, but it is a coded message. Taking a look at the spectrogram of the audio reveals a hidden message which reads "- project: sanctifier -".

Project Sanctifier

Inverted Tower of Babel

File No.: PRJ Sanctifier PID ---------------------------- 

“…… 42lab has always had concerns about AI viruses while developing their cloud servers. Before AI became more developed, the battle between viruses and anti-viruses was between human programmers. However, Viruses written by AI have extraordinary growth and development capabilities. AI can program viruses thousands of times faster than humans can, and the same goes for the speed at which they can deploy the viruses. Once Viruses by AIs become a reality, even the best network security engineers will be helpless. 

In order to eliminate this danger, 42lab started the research and development of Project "Sanctifier" in 2055 with the support of its parent institution IIQS, hoping to fight against AI viruses with AI antiviruses, so as to ensure the security of its cloud server.

Fortunately, Project "Sanctifier" was announced as successful in February last year, which not only became a milestone in the industry, but also laid a secure foundation for the "Neural Cloud" project which will also be developed  through cloud R&D this year. "

Project Sancitifer summary, purpose, and objective


The objective of Project “Sanctifier” is to design an AI antivirus routine for the 42Lab cloud service provider under IIQS’ autonomous research networks, based on traditional antivirus software technology and using AI technology as its core. It should demonstrate self-learning and growth abilities and be equipped with basic antivirus functions and the ability to counter AI viruses. This project will be headed by 42Lab of IIQS.


The main objective of Project “Sanctifier” is to satisfy the safety requirements for 42Lab’s servers.

  • In contrast to normal antivirus software, the product of this project will be stored on 42Lab’s cloud servers, providing comprehensive protection for cloud-based AI work.
  • The smart antivirus program “Sanctifier” will be equipped with self-learning and growth abilities, as well as providing a security foundation for “Project Neural Cloud”, which is still in its planning phases.


Project “Sanctifier” has the following key objectives:

  • Using mechanical learning and discrimination to find, evaluate and eliminate malicious code
  • To monitor its progress in real-time and to provide self-monitoring through process forking
  • Using its AI capabilities, it will provide active protection even in the absence of virus code signatures
  • Equipped with anti-AI virus abilities
  • Capable of autonomously repairing lightly-infected legal programs

Uranium_390: Director? Are you free now? I found some very unexpected things during maintenance...

Uranium_390: Just now, the team found some strange processes running on the system simulation layer during system maintenance. After some simple reverse-analysis, we found that they were very similar to  stuff we'd written in the past, both in coding style and operational logic. Some of them were so messy that we couldn't decode it, and the impression we got was that "some kind of malicious code or even a virus is masquerading as a normal process."

FEB 14 2056 16:42
[Uranium_390 has sent a vibrating alert]

Director: Check the transmission records and access logs. Then check our network gateway. See if there have been illegal accesses or signs of hacking.

Uranium_390: We've checked them all, but there are no signs of any illegal access.

Director: Is it possible that someone on the inside was trying to obfuscate the code?

Uranium_390: We can't rule that out. We're checking now. 

Uranium_390: Whoever did this was sending large amounts of junk-data in a DDOS attack against the security system in order to overwhelm the security system's processing capacity and thus overcome it.

Director: Initiate Plan S.

Uranium_390: The malicious process has been eliminated.

Uranium_390: Wait, it's back and completely unscathed, and it's launching another attack in the same way...

Uranium_390: No... This time it's also performing a port scan, as though it's trying to find a loophole in the security system. Looks a lot like an AI virus, don't you think?

Uranium_390: However, the security system's operational efficiency was clearly increased, because it quickly eliminated all the malicious processes. It seems "Sanctifier's" self-learning and self-evolution abilities are pretty good!

Director: Go do your work. I'll handle this.

"If you're going on an adventure, please take me along! As long as big sis is around you will NEVER be hurt, not even a little!" 

After the end of the War, scientific exploration of Relic Sites became the focus of the scientific world's attention once more. The EG 4.0 model Expedition Guardian Doll was developed to address this niche.

The EG 4.0 is furnished with military-grade close-combat weaponry, such as the high-energy taser blade Árvakr and the transformable high-frequency blade Alsviðr, which pushes her close combat performance to that of military Dolls and fully demonstrates the technological skills of 42Lab. Compared to the preceding three generations of EG Dolls, the EG 4.0 has met with widespread approval from expedition teams due to its reliable performance and its warmth and closeness, the latter of which is rarely seen in ordinary Dolls. As one of 42Lab's internal Doll, EG 4.0 has been entered into the first batch of "Project Neural Cloud" participants. 

(TL Note: In Norse mythology, Árvakr and Alsviðr are the horses which pull the sun, or Sól's chariot, across the sky each day.)

Email from Persicaria

To: 42Lab_NC_Project (text garbled)
Re: Concerning the development invitations to Project Neural Cloud

(text garbled)

My apologies for replying so late to your email. I've been considering your proposal over the past two weeks, and my answer is "Yes".

I read the planning document you sent about the key period, and like I said earlier, "Project Neural Cloud" will become an amazing field of technology, but it is difficult to avoid encountering technical problems in the process of realizing it. The solutions you proposed are also very innovative, and on that note, I believe my assistant will be able to help you.

You should know her, right? After all, her name is Persica, and she's identical to me in body type and looks. Also she was born in the labs of 42Lab (permit me to thank you for this once again), so forgetting her will be very difficult. She's a specialized model designed to focus on AI research, and before development began I insisted on maximum computing power for her neural cloud. Therefore I believe her abilities will prove to be very important in the development of "Project Neural Cloud".

In addition, I know the project supervisor of whom you speak. This professor has an excellent reputation in the academic world and I deeply respect the work they've done in the field of AI. I spoke with Persica and she would be very happy to work under this professor for a while, and she has expressed a desire to perform live testing after the development period ends. Our research here has recently been stuck in limbo due to certain practical reasons, and if changing environments will let her continue to grow, then I see no reason not to entertain a good idea. However, you must ensure her safety.

Now then, please go through the official flowchart again. Over the next few days, I'll be going to 42Lab with her to sign the appropriate documents.

I wish the project success, for everyone's sake.

Her appearance, body type, thought processes and so on are very similar to Professor Persica. Compared to the other 42Lab research Dolls, "Persicaria's" processing abilities and hardware are at the pinnacle of the industry standard. She also has extremely high compatibility with the field of AI technology, with excellent deep learning abilities.

After the revelation of "Project Neural Cloud", 42Lab is working with Professor Persica once more for her top-notch performance. "Persicaria" plays a key role in the development of this field of technology and is participating in the "Project Neural Cloud" beta test.

Magrasea Record

superserver Magrasea


The 42Lab super cloud terminal "Magrasea" is the world's first super heavyweight cloud server, built by 42Lab. The security of its cloud services is assured by their self-developed "Sanctifier". Not only does it satisfy the internal data storage and processing needs for 42Lab's internal projects, it can also offer cloud services to external clients on a rental basis. Their partners include Svarog Heavy Industry, Cyber Transmedia, Worldwide Omniservices, Terminal Life and other major corporations, as well as various NGOs, research teams, public service apparatus and even individuals. Many of 42Lab's upcoming research projects, like "Project Neural Cloud" and others, are all housed on this platform.

Sectors are different regions on the 42Lab superserver Magrasea. In order to ensure there is sufficient space to perform effective data simulation processing and to ensure data privacy and safety - even if there is the possibility of data exchange - in the strictest sense of the word, data from different companies or industries are stored in standalone Sectors. In addition, 42Lab's vaunted AI technology also supports the installation of standalone AI routines in each sector to help process cloud data. Naturally, "Sanctifier" defends the data and the normal AI routines within each Sector. 

The 42ab Sector was the first Sector to be built on the Magrasea superserver and it stores research data on 42Lab's AI research projects. Many AI programs are installed within the Sector in order to ensure high operational efficiency, and Sector management is in the hands of a 42Lab-developed next-generation high-performance AI. 

When "Project Neural Cloud" was first established, this Sector was once used as a temporary Sector to store project data, but as development progressed and the quantities of data involved grew massive, all "Neural Cloud" data was migrated to a standalone cloud Sector.

Magrasea: Military Sector

military sector cyclopes

The Military Sector was one of the earlier sectors to be built on the Magrasea server, and is also where the major industry leader "Svarog Heavy Industries" stores its military research data. Due to the sensitive nature of data in this field, Svarog Heavy Industries has deployed large quantities of sifter AI programs, and with the assistance of its close partner 42Lab, all data in the sector is also under the protection of "Sanctifier".

Magrasea: Computing Sector

enigma sector

The computing sector "Enigma" is a "special area" used to store research data related to quantum computers. Out of all the sectors in Magrasea, the computing sector has the best computing power and count. This sector contains the AI "Neumann" who was developed by 42Lab in collaboration with a certain high-tech company. It uses the scientist John von Neumann as a blueprint and incorporates the simulated cognitive data of many famous scientists. Neumann is currently performing quantum computing R&D in this sector.
