Before entering the Anistar Gym, the player must defeat their rivalCalem/Serena in front of it.
The Gym originally appears as a small, empty house, but standing at the center of its carpet causes it to burst into its true form, a maze-like, layered sphere of glowing pathways under a night sky riddled with galaxies and a comet and with constellations of various Pokémon like Pikachu, Lunatone, and Staryu hanging in between. The player must navigate three separate levels of pathways (blue topmost, green in the middle, and purple lowest) with warp panels connecting different levels where their paths overlap. Olympia is located on a circular platform on the lowest level. After being defeated, Olympia will offer the player a warp back to the original house.

The Gym is a building with a domed roof and several gold ring-like structures including one on the roof. Olympia has multiple Psychics attending there as her students.
In All Eyes on the Future!, Ash had a two-on-twoGymbattle against Olympia at the Gym, using his Frogadier and Talonflame against Olympia's two Meowstic. Despite the Meowstic's ability to redirect their attacks and the seemingly unpredictable Future Sight, Ash eventually managed to turn the match in his favor by making Pikachu count the time between Future Sight's use and hit, allowing him to use Olympia's signature strategy against her. This eventually cost Olympia the match, giving Ash the victory and earning him his seventh Kalos League Badge.
The Gym reappeared in Championing a Research Battle!, where Olympia told Diantha about the crisis she had foreseen would strike the Kalos region in the near future, and showed her the image of Zygarde she had seen in her vision.
