A youkai whose body is a mirror has the ability to make people fall asleep unconsciously and then use people's dreams to kill humans in their dreams.

There have been very few sightings, as most of the witnesses have died in their dreams.

Extremely difficult youkai, if you can't realize in time that it's your own dream, you can only be abused to death.

The main body is an extremely inconspicuous brass-edged mirror, perhaps because of this, it has not been discovered.

It has been solved by the Nine Empty Smoke first, but there is still news of frequent haunts in various parts of Izumo, so please be careful.
