Aniimo Season 1: the event schedule until 9 December, according to the game files
Season 1, "Departure with the Wind", runs in two parts: the first ends on 28 October at 23:59 UTC, the second starts after the 29 October maintenance and lasts until 9 December. Those dates are written in the season text in game. The rest of this schedule comes from the 1.0 client tables and hasn't been announced: Vein Abundance from 18 September, Tracing the Trail on the 20th, Aniimo Discovery and Glamour Star on the 25th, a new region on 29 October… All of it can still change.

The season’s two parts
The Season 1 text, visible in game, sets the frame:
- Part I: from 16 September to 28 October 2026, 23:59:59 UTC.
- Part II: after the 29 October update maintenance, until 9 December 2026, 23:59:59 UTC.
- Season Stamps: Windborn Stamps in Part I, Windchaser Stamps in Part II. Whatever is left at the end of a Part is converted into Credits.
- Stamp Shop: the weekly shop refreshes every Monday at 4:00 AM, the limited-time shop at the start of each Part.
- Season Achievements: four families of modes (Aniimo, Combat, Egg Heist, Homeland). Ranks and rewards reset at the start of each Part.
The season overview adds a “New Region” slot: “A brand-new region opens on Oct. 29, 2026!” What the files suggest about that region is covered in our article on the Whisperwake Isles.

Idyll Ecology Field Notes change every day from 16 to 21 September: the Institute publishes a list of Aniimo to catch, each target scores points only once, and the form has to match exactly.
Tracing the Trail: The Shadow of Legend
It’s the longest event on the schedule, from 20 September to 10 December. Its text: unusual signs of Legendary Aniimo are appearing everywhere, and the Institute is recruiting Pathfinders to investigate.
- Five investigation areas open one per day, from 20 to 24 September: Nimbus Fields, Forest of Falling Stars, Echoback Landing, Sea of Flowers and Tideblossom Coast.
- Each area has a clue. Petals drifting down beside the Branch, a stream of light above the Forest of Falling Stars, a moonlit reflection on the waters of Echoback Landing, abnormally growing thorns in the Sea of Flowers… and “two suns in the sky”.
- Each investigation needs at least two Aniimo, one of them a Leader. Aniimo that match the area’s preferences improve the reward, and Sparkling or Prismana Form Aniimo speed the investigation up.
- A Chance Encounter Gift may be added at the end, drawn at random from: +1 Potential for the Leader Aniimo (once in each Aniimo’s lifetime), Starcryst Essence, Capaseeds or Vein Essence.
According to the Legendary Journey rules, Tracing the Trail is also one of the sources of Irisalis Petals. Unlike the story or the Journey Quests, it won’t stay available once the Legendary Journey ends.
Companion Handbook: what the files say about this issue
The Companion Handbook has been live since launch, and how it works in general is covered in our Companion Handbook guide. For this issue specifically:
- The featured Aniimo is Fulmintis. Among the Advanced Edition rewards, the rules list a Prismana Form Fulmintis with Perfect potential and a Fulminous Soul, the item used to evolve Fulmintis.
- The issue ends on 28 October at 23:59 UTC, and all of its quests expire with it.
- The Prismana Fulmintis Egg will return in Season 3, “through Home-related gameplay”, according to the rules text. No date is given for Season 3.
What we’re leaving out
- Regional partnerships (TapTap, TikTok, Chinese social networks) and purchase-linked offers: they don’t concern every player, or they belong to the shop.
- The mystery Aniimo of “Who’s That Aniimo?”: that would spoil the game.
- Dates for an unidentified game mode running into 2027: without knowing what they refer to, they say nothing useful.
What this changes for you
- Before 28 October, 23:59 UTC: finish what you want of the Companion Handbook and Season Achievements, and spend your Windborn Stamps. After that, they turn into Credits.
- Every weekend until 26 October: save your Nurture runs for the Vein Abundance region.
- On 20 September: keep Sparkling or Prismana Aniimo handy for Tracing the Trail.
- On 23 September: if you also play on mobile, log in with the same account for Boundless Twining.
- Check in game whenever something opens. This schedule comes from the files: if the events screen says otherwise, the game wins. Confirmed events are tracked on our events page.
Frequently asked questions
When does Aniimo Season 1 end?
Part I ends on 28 October 2026 at 23:59:59 UTC. Part II starts after the 29 October maintenance and ends on 9 December at 23:59:59 UTC. Both dates are in the season text in game.
Does the Companion Handbook end with Part I?
According to the files, the current issue, built around Fulmintis, ends on 28 October at 23:59 UTC, at the same time as Part I. Its quests expire with the handbook.
What happens to unspent Season Stamps?
According to the season text, they are automatically converted into Credits at the end of each Part. Part I's Windborn Stamps therefore don't carry over to Part II, which uses Windchaser Stamps.
