Criminal Girls: Invite Only

This trophy is missable.

After reaching the last floor of Purgatory, you'll learn that you're not ready to face the final boss until one of your girls has been knighted. This involves using a key item on a girl who has learned all sixteen skills available to be learned through motivation. Before choosing a girl, make a backup save! The game warns you about this repeatedly for a reason! After knighting this girl, face the final boss, spend some quality time with the girl you knighted and watch the end credits roll. Then, load a backup save from before you knighted anyone and knight a different girl before tackling the boss again. Do this once for each of the seven girls to get all seven of these trophies. If you have no backup saves, this game does not have a New Game + feature, so you will have to start the game over from the beginning to get any missed character endings.
