The artist credit is listed as "Lico-chan (CV: Hime Vocaloid Engine 4 + Human Overdub)." This is controversial.

The Rumor: The "exclusive" nature of the voice track involves a hybrid AI-human performance. The baseline is an AI voice model (to create the fantasy "inhuman" resonance of Lico’s species), but every emotional outburst (fear, crying, laughter) is a real human session actress.

The Result: Lico sounds wrong in the best way. Her default tone is too smooth, like honey on glass. But when she screams "What's in the box?!" during the climax, the raw human crack in her voice is jarringly real. This duality is the primary reason the "eng" community is obsessed.

The final line of the audio is Lico whispering: "Your receipt... is the next errand."

Fans have already decoded the "exclusive" hidden message. If you reverse the spectrogram of Track 4, you see a repeating number: RJ01318927.

This is almost certainly the product ID for Eng Lico's Mysterious Errand Vol. 2. Given that the exclusive version sold out its initial digital stock (yes, digital "stock" is a thing on DLsite for limited keys), the demand for a sequel is high.

Theory: The "mysterious errand" was never the delivery. It was the relationship. Lico is cursed. Every time she completes a delivery for you, she forgets who you are. The "exclusive" ending loop suggests the listener has hired Lico hundreds of times, erasing her memory repeatedly. It is tragic, romantic, and horrific.

The "errand" attributed to Eng Licos is both a quest and a metaphor. Described in fragmented logs and fan theories, the errand involves retrieving a mythical artifact known as RJ01285997, an object supposedly encoded with the key to transcending the digital-physical divide. The numeric code is central to the lore, appearing in puzzles, ciphers, and ARGs (alternative reality games). Each digit—0 through 9—is rumored to represent a "gate" in a labyrinth of consciousness, a challenge only Eng Licos can solve.

In one popular fan-fueled mythos, the errand began in 1982, when a cryptic message was sent to subscribers of an underground zine:
"Eng Licos seeks the RJ01285997. To those who listen: the answer lies not in what is seen, but in what is felt. Follow the hum of the static."

This message, etched into polaroids and vinyl records, marked the first known step in a decades-long puzzle. Participants uncovered clues in obscure artworks, radio broadcasts, and even genetic codes, all leading to the enigmatic artifact. Whether real or fictional, the errand’s narrative structure mirrors the collaborative detective work of fandoms, blurring the lines between narrative and metafiction.

There are whispers in the archives. Glitches in the logbooks. And if you’ve been following the Licos saga, you know that when something is labeled "mysterious errand," it’s never just a simple fetch quest.

Today, we are pulling back the veil on the highly sought-after exclusive: RJ01285997.

For the uninitiated, Licos has built a reputation for weaving intricate, atmospheric narratives where every choice carries weight. But this exclusive English release? It’s different. It’s darker. It’s personal.

Buyers of the exclusive version (RJ01285997, not the standard edition) receive a secret MP4 visual file. It is not an animation, but a "kinetic typography" video. As Lico speaks, the English subtitles fade in and out with a glitch effect that reacts to the "heartbeat" of the box. This visual layer adds a fourth-wall-breaking horror element.

Eng Licos’ mysterious errand endures as a testament to the power of storytelling to inspire curiosity and unity. Whether the code RJ01285997 will ever be "solved" is irrelevant; what matters is the journey it has sparked. The errand challenges us to see the world as both a puzzle and a poem, inviting us to chase the threads of connection hidden in plain sight.

In the end, perhaps Eng Licos is not a character at all, but a metaphor: for the human condition, for the eternal balance between seeking and finding, and for the quiet certainty that some mysteries are worth living for. As the static hums on, we continue to follow it—because the errand is not over. It never has been.

*"To Eng Licos, with all who dare ask:
Where do the lines of the maze end?
Where do they begin?"

Given the information and assuming you're looking for guidance on how to approach or decode this:

Unlike the standard branching paths of the main series, RJ01285997 functions as a "locked room" scenario. You aren’t running across continents—you are trapped within a single, decaying estate. The clock is ticking, and the "errand" is not to deliver a package, but to uncover a truth that someone has literally blotted out of reality.
