An H-Scene recolleciton funciton (which can be accessed through the title screen) has been added, but it is also possible to unlock all scenes through a simple process.
(You’ve found a secret switch! Do you want to enable Full Unlock Mode for Scene Recollection? (options are “Keep Normal Setting” and “Enable Full Unlock Mode”)

Go to the back of the first floor in the Iliasville Inn (AKA Luka’s House), and there will be a switch that unlocks the entire collection in the location shown in the image.
Since this is a place you can access within the first minute of gameplay, even new players will have no problems.
There are no particular penalties for fully unlocking the scenes like this, and it’s also possible to flip the switch again to undo it.
