Directly under the game folder
\HengokuNite_Data\StreamingAssets
that exists in the
bandinsteam
file in your game folder, you can move or rename it to .bandinsteam so that the game will not load the sexually explicit assets and they will not be visible in the game.
Moving or renaming the file back to its original location will cause it to load the sexually explicit assets again.

Do not move or replace files while the game is running. It will cause the game to crash and other unexpected problems.
