The Nutaku version of the game is about one year behind DMM according to the Japanese wiki's Event List. I haven't played the Nutaku version since April 2020, so I don't know if any features were implemented early, late, or not at all relative to the one year gap. Nutaku censored all of the harem scenes around October 2nd, 2023, post #638 mentions it when it happened. The pre-October 2023 uncensored JPG files are in the 'Nutaku assets JPG files' archive I've linked to in post #686.
