Lingering Light is Xavier's 2026 birthday event, launching October 11, 2026, with the birthday-limited 5★ Memory [Xavier: Lingering Light] available until October 18. The story's central premise is Xavier learning to skateboard from scratch, described in the official announcement as 'flips, jumps, and reaching for the stars.' The event marks Xavier's in-universe birthday (October 16). A fan art contest using the hashtag #XavierLingeringLight ran alongside the event from October 11 to October 27, 2026. Full story details (location, plot beats beyond the skateboarding premise) could not be confirmed from available sources at time of archiving — the wiki had not been updated as of October 12, 2026; verify against in-game text or wiki on next update.
