r/ciconia

I've been thinking about Eua calling Satoko "Anomalous Spinal Cord Specimen LD-3105" and I ended up with a theory that connects Higurashi, Umineko and Ciconia.

​

We know several things:

​

\-Hanyuu belongs to a non-human alien species (Ryuun)

​

\-Hanyuu possesses powers related to fragments and worlds.

​

\-Rika gains the ability to loop through Hanyuu.

​

\-Eua calls Satoko "LD-3105"

​

\-Satoko develops fragment-traversing abilities similar to Rika's.

​

\-Satoko's behavior in Gou/Sotsu increasingly resembles what we know about Lambdadelta.

​

Most discussions focus on the possibility that LD stands for Lambda Delta and that 3105 can be read as "Sa-To-Ko." But I think LD-3105 is more than just a nickname. I think LD-3105 is an exact description. Eua did not give Satoko new powers, she was helping Satoko to remember her powers. She recognized LD-3105 and restored powers that had been dormant for a very long time.

​

My theory is that humans discovered members of Hanyuu's species long, long ago and began to experimenting on them in order to obtain their fragment-related powers.

​

The ability to move through fragments is arguably the most powerful ability in the entire When They Cry universe. If humans became aware of such a power, it would make sense for them to try to replicate it.

​

This could have resulted in a project called LD.

​

LD-3105 may have been one of the successful test subjects.

​

Instead of being born with the ability to traverse fragments, LD-3105 would be an artificial fragment traveler created through experimentation involving either Hanyuu's species or fragment-related technology.

​

This would explain why Eua refers to Satoko using a designation rather than a personal name.

​

From Eua's perspective, Satoko might not simply be Satoko. She might be recognizing a specific existence that has appeared before. A being known as LD-3105.

​

The really interesting part comes when looking at Lambdadelta.

​

Many fans believe Satoko eventually becomes Lambdadelta in some form. While this has never been explicitly confirmed, Gou and Sotsu create numerous parallels between them.

​

If LD-3105 is Satoko's true designation, then perhaps the progression looks something like this:

​

LD-3105 →Satoko→ Lambdadelta

​

Satoko would be the human identity.

​

LD-3105 would be the experimental or original designation.

​

Lambdadelta would be the final meta-world existence created after countless fragment journeys.

​

This could also explain why Lambdadelta seems so obsessed with certainty.

​

Imagine being an artificial fragment traveler forced to repeat experiments, loops, and worlds over and over until success becomes inevitable.

​

Eventually, certainty itself would become your defining principle.

​

It could explain why Eua immediately recognizes Satoko and addresses her in such a strange way.

​

If Satoko were merely a random girl from Hinamizawa, there would be little reason to call her "Anomalous Spinal Cord Specimen LD-3105"

​

But if Satoko is the latest manifestation of a much older existence, Eua's behavior suddenly makes a lot more sense.

​

An even crazier possibility is that Hanyuu's species, fragment travel, Bernkastel, Lambdadelta, and the mysterious references found throughout the When They Cry series all originate from the same ancient experiment.

​

In that scenario, Higurashi would not be the beginning of the story.

​

It would merely be one chapter in a much larger narrative that spans multiple universes and multiple ages of history.

​

What do you think about this theory?
