Blooming Osmanthus is a Seremoon Day (mid-autumn festival) login event running September 17 – October 1, 2026. Players check in daily to receive free rewards — Gold, Chocolate, Diamonds, Stamina, and Ascension Crystal boxes — culminating in two limited stickers, Golden Osmanthus and Osmanthus Jade, on day eight. Claiming each day's reward triggers a themed companion dialogue line. No new Memoria shipped with the event; its value is cosmetic and phone-message flavour.
