Cirrus's Diary is an item given to the player from Fire Opal as part of Removing Cookies and Browsing Data quest. This is one of the two pieces of evidence needed to compare the handwriting on Flan's sign. Since there was no other option for Cirrus to give a handwriting sample, Fire Opal gives the player his diary.


Prior to OSE 9, it had a selling price of 0 bits, though it cannot be sold. Its description originally read: "Cirrus's personal diary. Maybe just a peek?"
