Keys and Chests
There are four hidden keys. Get the chest upgrades before a long sorting route because High Jump, Run, and extra carry capacity save time on every later trip.
| Image | Key | Where to find it | Chest | Reward |
|---|---|---|---|---|
 | Crimson Octagon Key | At the very start of the game, look straight ahead. The key is hanging under the crest / wall emblem in front of you. | Octagon / crimson chest | High Jump |
 | Golden Diamond Key | Near the crimson chest area, jump onto the stair railing decoration and look inside the vase. The key is inside the vase, not on top of it. | Diamond / golden chest | Carry Capacity +3 |
 | Emerald Club Key | Find the scale table, then check the bench to the right of it. The key is buried under a pile of books, so clear the books off the bench. | Club / emerald chest | Run |
 | Azure Star Key | Walk to the back wall of the second floor, away from the staircase. As you face the back wall, the key is on top of the last bookshelf on your right. | Star / azure chest | Carry Capacity +2 |
Recommended Order
Section titled “Recommended Order”- Crimson Octagon Key first, because it is at spawn and unlocks High Jump.
- Golden Diamond Key next while you are still near the crimson chest and stair rail; it unlocks Carry Capacity +3.
- Emerald Club Key before the far second-floor pickup, because Run saves time on the rest of the route.
- Azure Star Key last for Carry Capacity +2; it is the longest walk and is less annoying after Run.
