This has nothing to do with game progression, but we're going to be creating different costumes for Lumisa.
One of the problems with this is that we can't actually create them until the main character's movements and animations have been fully finalized (since having to make just one adjustment means having to fix every single costume), and so now we're finally about ready to start working on them.
Those of you who have received costume keys as rewards will be receiving a file separate from the game from which you can obtain the keys.
Once the keys are applied to the game, you'll see a number representing the number of keys you have at the bottom-right side of the title screen.
These keys will allow you to open up costume treasure chests in the game and add the costumes to your inventory.
Players who have not received costume keys as rewards will have to acquire them by fulfilling certain conditions in the game.
Also, adding reward costume keys will only work on the PC version.
We unfortunately don't have a way to add this feature to consoles...
The merit of getting costume keys as rewards is that you'll be able to obtain said costumes before everyone else.
But either way, the costumes are hidden inside the ruins, so you won't be able to get your hands on them right away anyway.
