Window 3's 'Slime Marsh': A First Statistical Link in the Color Changes — Still No Proof of Awareness

Stable Window 3, in the Inagi valley of western Tama, has been in service since June 2025 and has long been considered one of the quieter of the five windows in terms of newsworthy observation. In Lineage 88 — the Division's provisional name is "the Slime Marsh," and this paper uses it too — a translucent, gelatinous organism, popularly called a "slime," has been recorded as the dominant form of life. Individuals have repeatedly been seen gathering while shifting body color, but no human or human-like figure has ever been confirmed there.

An individual believed to be the same one has often appeared near the glass, changing color in what seems to track the movements on this side — long a topic of talk among window keepers who wondered aloud whether it was "watching." Until now, nothing had backed this up beyond impression.

The Dimensional Survey Division announced on the 11th the results of a statistical review of several weeks of observation footage. It found a weak but not clearly coincidental correlation between the timing of the creature's color changes and the lighting or staff movement on the observation-room side. "Until now this was a matter of feeling, of 'it looks that way,'" an official said. "This is the first time the numbers themselves have shown something hard to write off as pure chance."

Even so, the correlation itself was not strong. An outside researcher who handled the statistics cautioned, "This shows no causal relationship. If the room's light level changes, something else on our side may be changing in tandem, and we could simply be mistaking that for a response from the individual." The Division holds the same line: "This is nowhere close to proof that it is 'watching.'"

One keeper who logs entries in the window room said, "At some point, that individual just picked up a name on its own. I don't know who started it, but everyone calls it 'the Watcher.' I always had the feeling the color changed right around when someone moved the desk lamp. I'm honestly relieved to have a number behind that instead of just a feeling. But what it means — I still can't say anything about that."

According to the Division, it remains unconfirmed whether the color changes function as language in any sense we would recognize, or are simply a physiological response. "We must not decide whether there's intent on the other side based on a correlation coefficient alone," an official said. "All today's result gives us is one more reason to keep watching."

As previously reported, the Division has said it will convene an outside advisory panel in November to weigh its policy on long, dense observation and the ethical question of whether continued viewing is appropriate. "If there's apparently some kind of response on the other side, the weight of continuing to observe grows heavier," an official said. "We want this included in what the panel considers."

Merchandise vendors have already inquired about products themed around "the Watcher," the Division says, but it intends to use this announcement as an occasion to sort out how such imagery and names should be handled — a matter still under review.

Window 3 remained under observation as of the morning of the 12th, with the next statistical pass expected within the month. "Whether or not there's intent over there, how we keep the record doesn't change," an official said. "But I think this has made the way we keep it a little more careful." This reporter noted: "A number doesn't rule out coincidence. Writing that down without pretending otherwise is the work of this desk."
