The web novel is what the author created first. It available freely at here, if you can read Japanese.

The light novel is rewriting of the web novel while also adding minor/major details, fixing plotholes, etc that the web novel has. However, for most of the time, web novel and the light novel is the same structurally except on certain things that I have said. It also available commercially both in Japanese and English.
