The fourth set in the Pokémon Mezastar Gorgeous Star series was released on February 8, 2024. It consisted of 83 tags and was the eighteenth set overall.
A returning feature from the previous set was the chance for Terapagos to appear during Get in Battle! mode. The Tera Pokémon could shield one of the player's Pokémon during an opponent's attack and reduce any damage received. This feature was in place for the duration of the set.
Players who used a Memory tag at any time during the period of February 8 to April 10, 2024 would earn a Weekly Stamp—those using a Memory tag with the same profile in a subsequent week would earn another Weekly Stamp. The reward for reaching two stamps was a Mezastar logo T-shirt Dress-up Item. The four- and six-stamp rewards were a Superstar Sensor, which would identify the location of a Superstar Pokémon at the start of Get in Battle! mode. The five-stamp reward was a Garchomp Emblem, which granted the chance to add Garchomp to the player's Support Pokémon roster during Get in Battle! mode. Players with Memory tags could also obtain up to three new Partner Pokémon: Venipede, Budew, and Swinub, which could be evolved through to their final stages by accumulating Star Points. Two campaign periods were held during this set, during which players could earn double Star Points—the first was between February 22 March 6, 2024; the second was between April 4 and 17, 2024. Players using the Mezastar Club at any time during the duration of this set could also receive a digital Support Pokémon Ticket for a Krookodile and a Present Ticket to unlock a spring pattern top Dress-up Item.

The Trainer and Battle lineup for this set included two returning Trainer classes, Multiple Part-timer and Fledgling Trainer, plus two new Trainer classes in Waking Boy and Party Lover. Momoka made her third appearance in a row and featured as the set's Star Trainer. Players with a Mezastar Club account could redeem Battle Tickets for each opponent and unlock new customization options for their avatar. Between February 22 and March 30, 2024, players could challenge Star Trainers Kinika and Yūsuke in a Trainer Tag Battle.
