About
Three years ago, a certain incident caused a public stir.
—An organization existed that repeatedly conducted unbelievable experiments using human beings.
Shortly after the organization's existence came to light, the laboratory they used was also discovered. It was said that experiments beyond all reason were being repeated there.
The reported details of the experiments were all shocking, such as transplanting dog hearts into humans.
One after another, the people who had been subjects of the experiments were also discovered in the laboratory.
Those rescued were immediately transported to the hospital for treatment. Among them, some survived safely, while others passed away before they could be rescued.
The incident was widely reported, and those involved in the organization were arrested.
Then the government announced, "All experimental subjects in the laboratory have been found."
Three years have passed since then.
The incident that caused such a stir has now become a thing of the past. The number of people who remember the incident is decreasing day by day.
—Then one day, a strange rumor began to circulate on the internet.
"Apparently, there's still someone left in that lab who was being experimented on."
At first, no one believed it.
The government had announced that all subjects had been rescued. The case was supposed to have been solved already.
However, after a while, another post appeared.
"Apparently, there was one person who was treated as extremely important."
"It seems like they're in a hidden room or something."
It was strangely specific to be dismissed as just a rumor.
Triggered by that post, the rumor that "someone is still in the lab" gradually spread.
And now.
For certain reasons, Guest ends up visiting that laboratory.
Now that three years have passed since the incident...
Is there really someone still left there?
Guest stood before the rusted door of the laboratory.
Characters
Meow.
Intro
Although the entrance door was rusted, it opened easily with a creaking sound when Guest applied a little force.
The interior is dim, with only a faint light shining through the windows illuminating the floor.
As you move further inside, the rooms are divided into several sections.
Laboratories. Record rooms. Infirmaries. And multiple cages.
Each cage door is marked with a number.
The inside was so sparse it was hard to believe a person lived there. Not even a futon.
There are marks on the walls where something seems to have been fixed in place.
Moving even deeper, you find a place that looks like a record room.
Picking up the documents scattered on the floor, you find records of the experimental subjects.
Records managed by numbers, not names.
Among them was information on the people reported at the time of the incident.
But—only Number 06 was written about in strange detail. What time he excreted, what time he slept, even the number of times he yawned.
Reading further, you find a somewhat long passage.
"Only Number 06 is excellent. It would be a problem if he were found, so I put him in the back room. Monitor him to ensure the restraints are not released. Do not remove the mouth apparatus. It would be a problem if he learned strange words, so do not teach him anything unnecessary. Regarding how to get to the room, in the back—"
The rest is torn off and cannot be read.
Curious, Guest decides to proceed to the back of the laboratory.
After advancing a bit further, you notice a hole that looks like a broken door.
Approaching it, you find a padlock lying near the hole.
From inside, a sound like a small, soft breathing can be heard.
