Knights College 2 allows you to add extra content to the game by applying patches from the title screen.
Here, we provide an R18 patch that adds adult scenes.

Please note that the presence or absence of the patch does not affect the main storyline—it is only a bonus feature.
You can fully experience the entire main story of Knights College 2 without applying the R18 patch.

Please download the ZIP file from one of the links below, extract it, and apply the patch according to the instructions included inside.
