Access the Secret Shop from a computer in MYSEKAI to buy Blueprints with Crystals.
The Secret Shop is only available with an active World Pass.

The Secret Shop lineup has 5 slots that rotate daily, and 3 that update weekly. Some slots will always feature Blueprints that you don't own.
The Secret Shop lineup is randomized and varies from player to player.

*Once you obtain all the Blueprints available in the Secret Shop, Blueprints that you own will start to appear instead.
*Some furniture Blueprints do not appear in the Secret Shop.
