Demon Thread

Demon Thread is a material in the form of thin, black-red strings and ropes which are nearly unbreakable, often used to regenerate or build structures. The only known current user of this ability is possibly Kotoblade (but not confirmed), though there were many past users that were erased from existence due to their usage of said forbidden ability.

## **History**

Long ago, a fallen multiversal god was searching for a way to extend his "natural" lifespan and prevent himself from becoming anymore weakened. Eventually, the being discovered a formula for the perfect material to suit his purposes, created by a legendary user of black magic. After a period of experimentation with the formula, the being spun the material, by synthesizing and deriving it from the silk of a Multarach spider. However, this string was only a conceptual prototype, and was not useful for much beyond repairing injuries. Thus, this project was abandoned by the being. Later, another being with a greater need for the string eventually came upon it, and used it to patch up and hold together his deteriorating body. Eventually, this string became more than a necessity to the being. It turned into a tool, a deadly weapon that he honed against his enemies. And it was this specialized form of the string that became the material Demon Thread. This being was the sole wielder of Demon Thread for a time, until some other beings and even entire races got their hands and/or other appendages on it, and they themselves began to use it.
The popularity of the ability eventually spread throughout the Omniverse, until it came to become a source of cosmic instability that caught the attention of Creator himself. Seeing the chaos caused by the widespread Demon Thread manipulation, Creator removed all instances of Demon Thread throughout the omniverse, expelling it into the Outside. It is rumored, however, that Destroyer had managed to procure some of the banished demon thread from the Outside and kept it for personal use and potentially giving it to other beings. However, this rumor is not confirmed. Eventually, Satoru later supposedly learned about the Demon Thread, and took an interest in what caused it to work the way it did.

## **Properties**

Demon Thread served many versatile uses. It is most commonly used, as was its original purpose, to patch wounds, rejoin separated parts, and hold beings together. It can be shaped in many ways, and even act as synthetic limbs or an entire body with which to house a being’s essence. This however is not an ideal situation, as while it can offer a temporary solution for missing a physical body, it does not permanently replace it. Demon thread can also be used to create traps similar to spider webs, with which one can trap prey. This would make sense, as Demon Thread is based off the silk of a Multarach.
One of the most highly advanced techniques of Demon Thread manipulation is its ability to "possess" beings. Essentially, the wielder of the thread attaches several of strings to a being, and manipulates the movements of the strings to, by proxy, also manipulate the movements of the being themself as well; Essentially like a puppeteer controlling a marionette. The being that is controlled has full awareness of what is happening, but cannot control their own movements as they involuntarily perform actions at the whims of the puppeteer.
