Introduction to the second dimension:

The second dimension (English name) :Two dimensions) is a specialized term in the ACGN subculture circle. It comes from "two dimensions" in Japanese, which means "two dimensions".

Japan’s early animations, comics, games and other works were all composed of two-dimensional images. From our perspective, the picture is a plane, so the virtual world created through these carriers is called animation enthusiasts "Second Dimension World", referred to as "Second Dimension". Among Japanese animation fans, it refers to the characters in animations, games and other works.

This term is widely used in the ACGN cultural circle as a term for the "imaginary world" or dream world, but ACGN is not the same as the second dimension.

The second dimension is a beautiful world imagined by human beings. "Second Dimension" is a type of culture, not a style.
