Description

Entity 13HRP – 0099 – Rainbow Straightjacket ranks as one of the most disturbing objects in the Hollow Reality Project. It acts both as a prison and as a predator. At first, it looks like a straitjacket made from glowing threads—bright bands of pink, blue, orange, yellow, and red that shift like a moving rainbow. The shifting light disturbs vision, and it seems to pulse with the heartbeat or breath of anyone nearby. Reports say the colours grow faster with quick breathing or match the rhythm of the heart, showing that the jacket links itself to the body.

Tests prove the material is not normal. It looks like Kevlar, yet it is far stronger. It starts at about one centimetre thick but grows to four centimetres during use. Under a microscope, the weave sometimes changes into flesh-like tissue. In addition, some areas look like skin, though they vanish when viewed too long. This shows it bends both sight and thought. People who touch it say it feels warm and alive, like a body waiting to close around them.

Psychological and Physical Effects

Wearing 13HRP – 0099 – Rainbow Straightjacket always leads to decline. Within one hour, subjects grow paranoid, insisting the jacket wants to harm them. Any attempt to remove it fails. By the second hour, the body burns energy at an extreme rate: most people lose about thirteen pounds no matter their size. While some look thinner and healthier at first, their minds break down into fear and panic. Soon, hallucinations appear—chewing sounds, whispers, and the sense of something pressing from inside the fabric. Brain scans show strong fear signals, much like prey facing a predator.

As time passes, behaviour worsens. Subjects rock back and forth, growl, and harm themselves. They often bite their own flesh while repeating lines such as “the jacket eats what it binds.” By the third hour, muscles waste away and organs shut down. Death always follows in less than a day. Witnesses say the eyes look hollow, as if the jacket has replaced the wearer’s will.

Instant Report ZADA‑12

One test with an underweight inmate ended in death within eleven hours. The body showed deep marks shaped like bite wounds, none of which matched the subject’s own teeth. This supports the idea that the jacket feeds on its own. Another test with a cancer patient showed mixed results. While the patient’s disease vanished, the same wasting process occurred. They lived longer but still reported chewing noises and feelings of cold in the chest. As a result, this raised debate: could the jacket target sickness while also feeding on the host?

Hypothesis

Most researchers believe 13HRP – 0099 – Rainbow Straightjacket is a living hybrid of cloth and flesh. It survives by consuming the host. While it may burn diseased tissue, it also eats healthy tissue without care. Some hope it might have medical use, but others argue its hunger makes that impossible. Furthermore, each use thickens its fibres, showing it grows stronger with each victim. There are also signs that parts of past wearers remain within it, leaving behind fragments of identity.

Instant Report ZADA‑13

A test for weight-loss use ended in disaster. The jacket refused to release the subject, even under saws, torches, and strong solvents. Over thirteen hours, the subject wasted to bone and died. The body showed bite marks all over, as if eaten from the inside. The jacket itself grew heavier and denser, and the fibres thickened. Moreover, microphones recorded chewing and swallowing until death. After this, all trials were banned. Still, some in the Council want to study it in secret, hoping to use it as a weapon or medical tool.

Interpretations

Some believe 0099 is more than flesh-eater—it is a predator of meaning. It blurs the line between clothing and creature, prison and predator. Its rainbow glow may be camouflage, hiding the truth of its hunger. Others suggest it stores voices of past victims. People who wore it for long hours claimed to hear voices of the dead urging surrender. If true, it not only consumes bodies but also keeps minds, turning into a store of stolen thoughts.

Containment

Entity 13HRP – 0099 – Rainbow Straightjacket is locked in a sealed case with seven magnetic locks. Only the full Council may grant access. Guards check it every hour, since even being near it causes strange thoughts, phantom touches, and bad dreams. Any theft attempt leads to instant transfer to interrogation.

If it binds to someone, staff must try removal with all tools, though success is rare. If removal fails, staff may ease the victim’s suffering until death. Above all, the main rule is simple: never see it as clothing. It is a living feeder hiding as fabric.

Conclusion

13HRP – 0099 – Rainbow Straightjacket is both object and predator. It locks victims while it feeds. Its beauty hides its hunger. Therefore, it proves that tools of control can become predators themselves. Though banned, some still want to test it. Until then, it remains a warning: the line between prison and predator is thin, and even cloth can consume.
