The HAPPY BIRTHDAY Shiraishi An 2026 event in Project Sekai: Colorful Stage! feat. Hatsune Miku runs from July 23 to July 28, 2026. On July 26, An's actual birthday, a birthday live will be held 24 times every hour starting at midnight, with first-time participation rewards of 2 An vocal cards, 1 An's Memory Bottle, and 100 An's Memory Fragments. A MySekai scenery contest themed around a party venue is also scheduled for that day. Players can collect Festival Dew (Turquoise Blue) by gathering Futaba and regular harvest items in MySekai and playing lives. Pouring the dew into the Celebration Tree in the Festival Garden yields An's Celebration Flowers, used to craft birthday-limited furniture and obtain titles and items. Crafting the Birthday Cake (An) unlocks a birthday party. Two gacha banners are available from July 22 to July 28: the [Shiraishi An] HAPPY BIRTHDAY 2026 Gacha featuring a new birthday-limited member, and the [Shiraishi An] HAPPY BIRTHDAY Memories Gacha with reruns of past birthday-limited members.
