Legilimency
There are 2 types of legilimency in the game:
Ginny
Summon her unofficially. A cloud of thoughts will appear above her. this cloud will display various faded objects, and only one will be bright and colored. This colored object is the key to the diary.
Main Girls
Summon them officially and choose "seat and relax". A cloud of thoughts will appear above the character, which acts like wheels in a slot machine. The correct answer is the most frequent object in the loop. The frequency of this object increases in proportion to how high your level of perception is.
If you enter wrong answer into the diary - the password is reset, and you need to summon a girl again and find out new key.
