Hida

ひだ or Hida ( Japanese:, English: , any pronouns) is a sentient being made of paper who can fold themself into different shapes. They also have the ability to sense the tearing of paper from even quite long distances.

Backstory
Hida was created in a lab to be a mass-produceable mascot with autonomy/sentience, but the researchers didn't consider the emotions of the being they created, causing a lot of suffering in the experiments. When Hida figured out how to cut skin with their paper edges, they escaped the research facility covered in blood.

Now, there are reports of people being stalked by Hida, and several other murders have been attributed to them, the victims in question being covered in many cuts, causing them to bleed to death. The majority of these victims have been found to be toying with similar ideas of animating objects for their personal benefit.
