A campaign featuring Yostar’s “Stella Sola” and GiGO will be held at GiGO locations nationwide from October 31 to November 29, 2026. Limited-edition prizes—including large acrylic stands and plush mascots featuring exclusive illustrations of the five characters dressed in starry-sky-inspired gowns and holding bouquets—as well as must-have clear cards and the “Stella Sora Yaki,” available exclusively at the Akihabara and Sasashima locations, will be on offer.
