The Gym is designed like a doll house. In order to battle Valerie, the player must go through a warp tile puzzle, much like the Saffron Gym in Kanto. After Valerie has been defeated, a one-way warp tile in her room can be used to return back to the entrance.
The table below shows how the Gym's teleporters are interconnected. The colors are meant solely as a visual aid.
The Gym appeared in A Fashionable Battle!. Its exterior appearance is similar to the games, though it also has a catwalk, which is used for fashion shows hosted by Valerie. During one of said shows, Valerie allowed Sawyer to have an official Gym battle with her. However, Sawyer was soon defeated, leaving him without a Badge for the time being.
The Gym's battlefield was shown in Fairy-Type Trickery!. It is a garden with wall-mounted digital displays, which are used when Valerie is making her entrance. In the same episode, Ash had a Gym battle with Valerie, eventually emerging victorious and earning his sixth Kalos Badge.
