Finding Small Keys in the Village and Castle
Starting from Chapter 2, you can find "Small Keys" scattered throughout the village and castle. These keys are used to unlock nearby shelves, so it's advisable to use them as soon as you find them.
One Key Per Shelf
Unlike other keys, a "Small Key" is used up each time you unlock a shelf. Fortunately, the number of keys matches the number of shelves, so feel free to use them without concern.

You can find the "Shrine Key" in a treasure chest near the right side of the Wharf shortly after Chapter 4 begins. Until the story progresses further, focus on collecting this item rather than exploring the shrine.
Limited Time for Collecting Treasures
During Chapter 4, be sure to collect treasures from the "Cave on the west side of the Lake," "Lakeside Settlement," and "Quarry." These treasures become inaccessible in Chapter 5 as the boat will no longer be available.

The Key Bundle becomes available on the second floor of the castle after you switch to playing as Ashley in Chapter 9. To find it, manipulate the hidden staircase in the bookshelf area. Use these keys to unlock doors and shelves by matching the design on the lock to the decoration on a key handle.
Don't Miss Ashley's Section
While controlling Ashley, make sure to unlock all "Treasure Chests with keyhole decorations." Once gameplay switches back to Leon, the Key Bundle will no longer be available, causing you to miss out on collecting three treasures.
