Cosmic horror refers to fear from a transcendent being that we cannot think of.
As there is a saying that human fear comes from ignorance, focusing on the fear that comes from ignorance,
It covers topics such as human powerlessness and weakness, and the fear of higher beings.
In this field, the worldview of the Cthulhu myth is representative, and there are a lot of derivative works.
I think it's a good genre for various creatures to appear, so it's a genre I really like!
