Shared Bloom is a Mini Event running September 8–17, 2026, explicitly a rerun of 2025's Spring Arrives event. At the Linkon Floral Exhibition Hall's Old Town Flower Day, the player and a chosen companion create a floral vase together through the Floral Fusion matching mini-game (five stages, plus an endless Infinite Fusion mode). Points convert to Floral Seals that unlock Gold, Wishes, Core Energy, a Chalk Attack headwear item, and a Treasured Days chest. It carries no new story chapters or Memoria — its intro/outro narration frames the vase as a keepsake of spring memories.
