Ittan-momen

Origin
The Chōchin-obake is a yōkai from Japanese folklore. It was described by Toriyama Sekien as a bolt of cotton cloth that flies through the air at night and suffocates travelers by winding around their heads. Although one was collected in the Kagosima Prefecture in 1835, reports as recent as 2004 indicate there may be more present across Japan

They may be created from the local custom of raising a white cotton flag as a symbol of mourning during burials.

Effects
Considered actively hostile, this artifact is known to hunt down victims at night by flying on strong winds. once it finds an isolated victim it will swoop down and envelop their entire head in an attempt to suffocate them. if the victim dies, the artifact will unwind and vanish into the sky. This may be a type of "feeding", as it will only attack one person every few days regardless of access to potential victims.

The artifact will also be rendered inert if it is damaged at all. Agents were able to slice the artifact with a small dagger as it attacked, causing it to fall to the ground and writhe for a few moments before ceasing movement. It is currently wrapped in a bolt and held in place with a sturdy pin on a Warehouse shelf. Although it has occasional activity it has not yet managed to escape, and agents are reluctant to unravel it to determine the extent of its abilities, if any remain, in its current state.
