What is Legendary Journey: Trail of Butterfly Shadows?
Trail of Butterfly Shadows is the first of the two Legendary Journey bars on the calendar. It runs from 16 to 25 September 2026, ten days, and hands straight over to Legendary Journey: Walking with Irisalis & Gift of Blessing on the day it ends.
The official calendar lists only the dates. No notice on aniimo.com names the event, and it does not appear on the closed beta calendar, so nothing is published about what the trail is, which Aniimo it involves, or what it pays out.
The only structural fact the calendar gives is the handover: the two Legendary Journey windows are back to back, not overlapping, which is why they share a row.
Dates and windows
| Window | Dates | Days | Featured Aniimo | Status |
|---|---|---|---|---|
| Window 1 | 16 September 2026 to 25 September 2026 | 10 | TBD | Starts tomorrow |
Dates are the UTC+8 calendar days the official calendar publishes. The source gives no time of day, so treat the last date as the whole of that day in UTC+8 and do not leave a reward to the last hour of your own.
Rewards

Tips
Ten days from launch day is the shortest Legendary Journey window on the calendar, and it is the first thing on the calendar to expire. 25 September 2026 is the deadline.
It is the only launch event that overlaps the entire opening stretch of the game, so it is worth opening the events menu on day one to see what it asks for.
The Legendary Aniimo encounter the dev team described for launch is built around crafting a Legendary Aniipod. If you want to prepare for the Legendary Journey row generally, the Legendary Aniipod page on this site collects what is known.
