Congratulations! You have beaten the whole game! If you followed the guide from start to finish, you should have every trophy except Librarian, Whisper Completionist and Date a Completionist.
Librarian is simple to get, simply go to Gallery > Library.
If you somehow missed a memory for you can go to Gallery > Memories and scroll through the list and you'll be able to see who you are missing it for and where you are missing a memory.

Whisper Completionist seems like a pain at first glance but is not that annoying to achieve if you know what to do. You need to hear the every System Voice. This basically means need to hear 5 system voices for each of the 10 heroines and 4 other system voices from 2 other characters.
For the 10 heroines you need to hear:

• The title screen voice line.

• Loading screen voice line.

• Yes and No voice lines.

• Voice line when you view a CG in Gallery for each heroine.

And there 4 other voices i mentioned are from Reine and Maria.
Enter Gallery > Memories to get Reine's first voice line. Watch any memory to get Reine's second voice line.
Enter the Library to get Maria's first voice line. Click on any option listed to view more info to get Maria's second voice line.


CG voice lines are easily achieved by viewing 1 CG for each heroine.
Title Screen voice lines can be easily gotten by starting a new game and exiting to the title screen. But before you start getting the title screen voice lines, let us make this easier and get every voice line without having to rely on RNG.

Enter Sound Settings and mute every heroine except the one of the heroine's voices you want to get. For this example i have left Tohka unmuted.
Simply just start a New Game, go to System, click Title but do not click Yes, click No. Now click Title and press Yes for both messages. Upon returning to title screen you will hear Tohka do the title drop and say something afterwards.
You have now gotten all of Tohkas voice lines. Now simply return to Sound Settings, mute Tohka, unmute someone else and repeat until you get the achievement.
Upon unlocking Whisper Completionist you will also get Date a Completionist. Congratulations, you now have every achievement.
