The event runs through 19:59 on August 5.

The event features 5 talents: Oozora Subaru, Shiranui Flare, Shirogane Noel, Tsunomaki Watame, and Otonose Kanade.

To coincide with the event, a total of 6 songs were added, including the new track “Boom! Boom! Tropica Vacation.” The gacha “Sunny Summer Vacay Gacha” is also running in parallel. The gacha period runs from 11:00 on July 28 to 10:59 on August 7 (both JST). The gacha features new ★5 versions of the 5 talents above in park costumes and live costumes.
