solution is simple, if you hate mosaic, just don't waste a single minute of your time or a single mb of bandwidth on this game. it is 100% censored with mosaic included images already in the game, so no adult patch is going to work and no anti mosaic will either.
The severe prudish way people in Japan behave is mostly why the population decline is already going to be huge with nearly 50% (44%) of the population over 65, and only signs of negative growth which will worsen significantly once the older generation die (30% over 30 or over, very severe limited growth with signs of a downward trend) and those under 30, have pretty much given up. Thats what prudish behavior and too honorable to do anything get you, frankly it is beyond insulting, this behavior belongs in the edo time period not in 2023!
