Report

Journals, also known as Reports, are a recurring feature in the Kingdom Hearts series. It keeps track of the progressing storyline and records information on characters, enemies, game records and more.

Sora's journey in Kingdom Hearts, Kingdom Hearts: Chain of Memories, and Kingdom Hearts II are recorded in Jiminy's Journal by Jiminy Cricket.

Kingdom Hearts Chain of Memories
In the Reverse/Rebirth storyline, data is recorded in the D-Report; the "D" stands for "Darkness".

Kingdom Hearts 358/2 Days
Roxas's Enemy Files contains descriptions and pictures of the various enemies, along with a list of the treasures they drop when defeated.

Kingdom Hearts Birth by Sleep
Aqua, Ventus, and Terra each have an individual set of Reports in Kingdom Hearts Birth by Sleep, which have similar coverage of their progress.

Each journal contains a Story section, which summarizes the character's adventures in each world they have cleared. The pages of Xehanort's Report that have been obtained can be found under the Secret Reports section, while the Game Records section lists the character's progress in the Mirage Arena, mini-game records, and Hit Counts for Shotlocks, Dimension Link, and Finish commands. In the Final Mix versions of the game, the Battle Mission is added into the Game Record section.

The Character Files and The Unversed sections cover characters and enemies, respectively, that have been encountered so far. The Command Collection keeps a record of all the Deck Commands, Shotlocks, Dimension Links, Finish Commands, and Abilities that have been obtained, while the Treasures section tracks the Treasure Chests that appear in each world.

In the English and Final Mix versions of the game, the Sticker Album appears in the Reports, as well. When a section or sub-section is fully completed, it is marked with a stamp.

Kingdom Hearts Re:coded
The Debug Reports in Kingdom Hearts Re:coded consist of five sections covering various facets of the game, along with a record of the level of completion for each section.

The Trophies section shows the trophies that have been earned on the top screen and tracks various game records and progress towards earning trophies on the bottom screen.

The Collection records all the Stat Chips used and the Bonus Boosters and Cheat Tuners activated on the Stat Matrix, and the Deck Commands and Keyblade, Finish command and Accessory chips that have been obtained.

The Story section summarises the events in each completed chapter of the game.

The Enemy Profiles show all enemies that have been encountered, and it includes descriptions, item drop data, and how many times a type of enemy has been defeated. The Character Files contains short biographies for each encountered character, as well as their conversation sprites.
