Log Horizon (Web Novel)

The Log Horizon web novel is how Mamare Touno first published the Log Horizon series before it was picked up for a light novel release. He began uploading chapters on Syosetu on April 13, 2010, and has continued publishing web novel chapters there even after the series was officially published.

The web novel is effectively a rough draft for the final light novel publication, and occasionally has major changes from the final product.
