Window 5's Recorded Sound Made Public — First-Generation Drifters Say 'The Melody Resembles Our Lullaby'

The TDA's Dimensional Survey Division made part of the roughly three-second recording from Window 5, "the Sword Country," public to the press on the afternoon of the 1st — the voice-like sound previously reported from the 30th. Until now, officials had described it only as "a short, inflected sound"; this was the first time the recording itself was disclosed. The division played it three times under identical conditions at the briefing. A staff member, prefacing the release by noting it was "captured mixed into market crowd noise, not isolated as a standalone sound," explained the decision to release it: "We judged that putting it in the hands of non-specialists, rather than holding onto it ourselves, would broaden the range of possible analysis."

For the release, the division arranged for Ushio Kishiura, 74, the music teacher who transcribed the Shore Lullaby, a first-generation Drifter, to listen to the recording. After replaying it twice at the briefing, Kishiura testified, "I can't say for certain, but the melody feels similar to the lullaby." She added, choosing her words carefully, "The lullaby has only ever been passed down mouth to mouth, from one first-generation Drifter to the next. I don't know myself whether the sense of similarity comes from nostalgia, or because it really is similar."

Tane Kishitani, 101, the oldest living first-generation Drifter, who was present and heard the same recording, reportedly responded briefly: "That tune — I feel like I heard it somewhere far away." Kishitani is, as previously reported, among the first generation who "decided not to speak of home," and the window keeper attending said hearing her respond to this kind of question at all was unusual.

At the briefing, the division reiterated its standing position that "there is no evidence the other side is aware of us," adding, "The impression of a similar melody is valuable, but it doesn't demonstrate an academic match. We can't rule out that it's simply a coincidental resemblance." As previously reported, the lullaby's lyrics remain of "undetermined meaning," and the original score remains unpublished, kept at the Kishiura family's household altar. No lullaby audio itself was used in today's release.

A division audio specialist said, "We don't rule out that it came from a human voice, but both the vocal organs and method of production remain unknown. A sense of similarity can be a starting point for analysis, but we won't treat it as an endpoint" — maintaining the same reluctance to rush toward a connection seen in the handling of Lineage 7, "the Lit City."

News of the briefing spread quickly on social media immediately afterward, and Toshimado Café, previously reported, saw more visitors than usual on the evening of the 1st. "Several people told me they came because they'd heard it sounded like the lullaby," said owner Saku Miyai, with a wry smile. "There's nothing here they can actually listen to, though." One figure involved in Drifter-rights advocacy, speaking anonymously, said, "I've heard from more than one first-generation Drifter that it feels like a small hole has opened in fifty years during which nobody talked about home." Independent researcher Karin Kokonoe, by contrast, urged restraint: "If expectations run ahead of the facts, there's a backlash later. Stopping at 'it feels similar' is the most honest place to leave it."

As previously reported, today's recording is already slated as the fourth agenda item for the outside advisory panel (to be chaired by Etsuko Kajiura), set for its first meeting in early November. The division said the lullaby-resemblance testimony would also be taken up there. Kajiura, through the division, offered: "The sense of similarity itself is a valuable record. Not rushing it toward a conclusion is the only way to honor that testimony."

As previously reported, the Shore Lullaby is a thirteen-verse song said to date from the 1975 mass arrival, its lyrics left as "undetermined meaning" aside from three inferred words — sea, window, way home. The original score remains at the Kishiura family's household altar, with disclosure still planned only after Kishiura's death, and even its ceremonial performances have gone without a translation handed out, passed down only mouth to mouth. One figure with the ceremonial-groups federation described the weight of hearing that a sound from the far side of the one-way boundary might resemble it: "For fifty years there was no way to check that song against anything. This is the first time a point of comparison has appeared."

The window keeper who captured the recording reportedly wrote in the log, "For those three seconds, amid the market noise, it felt like the air itself changed density." The division cited the entry at the briefing as reference material while drawing a line around it: "That's the window keeper's subjective impression, kept separate from the observed facts." Even so, the staff member handling the briefing admitted, in a moment that drew a soft laugh from the room, "Personally, I keep playing it back myself."

Kishiura, who as previously reported leads the roughly thirty-seven-member choir centered on Bayside Third Junior High School, said she had not yet decided how to tell the news to the children. The choir includes many students of mixed Drifter heritage, and Kishiura said, "Some of them will be fine leaving it at 'maybe similar,' and others won't be able to stop wanting to know. I don't think there's any need to rush into telling them."

The one-way principle holds, as ever. Whatever melody may have crossed over, all that can be sent back from this side is the act of listening to the recording again.
