What to know
- Lunar Aqua is Diana’s first unlockable outfit, separate from her default Cradle Jacket.
- You get it by earning a Blackout on the Trainee Board, meaning every slot on that board must be opened.
- The Trainee Board is the first Stamp Card board in Mr. Cabin’s Stamp Club.
- This is a cosmetic reward tied to progress in the Stamp Club system, not a combat upgrade.
Pragmata gives Diana multiple outfit options, and Lunar Aqua is the earliest special look you can unlock through normal play. The requirement is simple on paper, but it still depends on progressing far enough to access the Stamp Club and then fully completing the first board.

How the unlock works
The game’s outfit system uses Stamp Club boards as reward tracks, and Lunar Aqua is tied to the earliest one. A Blackout means you open every slot on the board, so the outfit does not appear until the full board is cleared.
Step 1: Reach the Stamp Club
You need access to Mr. Cabin’s Stamp Club before you can work toward the outfit.
The Trainee Board is part of that system, and it becomes available early in the progression path.
Step 2: Work through the Trainee Board
Open the board’s available slots as you earn the required progress or currency for the Stamp Club.
The outfit is not tied to a single hidden pickup, so the entire board matters.
Step 3: Complete every slot
A Blackout is the key requirement.
Once all six slots on the Trainee Board are opened, the board is fully cleared and Diana’s Lunar Aqua outfit is unlocked.
Step 4: Equip the outfit
After unlocking it, switch Diana’s appearance from the outfit menu and select Lunar Aqua. It functions as a style choice, so you can use it without changing how Diana plays.
Location and progression
The unlock is tied to the Cabin hub and its Stamp Club progression rather than a field pickup in a mission area. That means your focus is on returning to the hub, advancing the Stamp Club board, and clearing the Trainee Board fully before the outfit becomes available.
Tips for unlocking Diana’s Lunar Aqua outfit faster
Focus on progressing efficiently through the game until the Stamp Club becomes available, since the outfit is locked behind that system. Once you have access, make sure you are not leaving any slots unfinished on the Trainee Board, because a partial clear will not award Lunar Aqua.
The reward is straightforward, so the main mistake players can make is assuming one or two slots are enough. The game specifically wants a full Blackout before it grants the costume.
Diana’s early outfits
Diana’s default look is the Cradle Jacket, while Lunar Aqua is her first unlockable alternate outfit. That makes it the natural first cosmetic target for players who want to change her appearance early in the game.
The TL;DR of it is this – to get Diana’s Lunar Aqua outfit, unlock the Stamp Club, clear every slot on the Trainee Board, and claim the Blackout reward. Once that is done, the outfit is yours and can be equipped like any other cosmetic.
