Stella Sora 1.13: The August 3 Cut-Off, Suntide Willow to August 10, and 20 Free Pulls
Version 1.13's main event and its Event Shop closed on August 3, 2026 at 12:59 UTC-7. The Suntide Willow banner and the log-in event keep running for seven more days, to August 10 at 19:59 UTC-7.
Those two stamps are printed on two different official cards, and nothing on the store page reconciles them. Anyone who read "August 10" as the patch deadline lost the Event Shop a week early, and the event-limited 5-star Runic Disc bought there with Sunlit Conch went with it (T3, GameMarket.gg; the official card shows the reward strip but does not name the currency).
Version 1.13, "Sunlit Breeze, Azure Seas, Checking In for A Cozy Summer~", has been live since the July 20 maintenance. Yostar prints every date on every card in UTC-7, without exception.
Every 1.13 window, with its own end stamp

Two clock conventions run through that list. Content, modes and Event Shops close at 12:59 UTC-7, one minute before the 13:00 daily reset (T3, community clock). Banners, 3D appearances and story chapters end at 19:59 or 21:00 instead.
What closed on August 3 at 12:59
The main event ran a check-in structure named for the patch, "Sunlit Breeze, Azure Seas, Checking In for A Cozy Summer~", from July 20 after maintenance to August 3 at 12:59 UTC-7. Its reward strip lists Dappled Sunlight, the event decor item, a Cerulean Ticket, Star Emblem Polisher and Drop of Purity.
The Event Shop closed on the same stamp. Missions paid Sunlit Conch, and the shop's headline stock was an event-limited 5-star Runic Disc, which is the only free 5-star in the patch (T3, GameMarket.gg). No official card names either the currency or the disc, so treat both names as reported rather than confirmed. The window itself is T1: it is printed on the event key art.
Summit Show, subtitled "Cat-stle Siege", ran arena fights against Trekker illusions over the same 7/20 to 8/3 window (T3). The official preview card confirms the Summit Show entry exists but prints no subtitle and no dates.
Suntide Willow is Willow's swimsuit alt, not a debut Trekker
The Japanese reveal card names her ウィロー（水着）, Willow (Swimsuit). The Korean card reads 윌로(여름) and the Chinese 薇洛（盛夏）. She is the summer variant of Willow, the Trekker who runs the Trekker Association's local branch in Emor City, and every non-English name says so.
She is 5-star and limited: the JP card stamps 限定, the EN banner is labelled Exclusive. Her element is Aqua (T1, official Trekker Introduction) and her position is Support, Ranged, style Steady (T2, community wiki). Her weapon field reads "Warning Smile", her birthday is December 14, and her Japanese voice actress is Hitomi Nabatame.
Her main skill, Sonic Bubble, switches weapon modes on the Main Skill button, Bubble Machine to Megaphone and back. Bubble Machine auto-attacks inflict Bubble Mark; strikes 1 to 3 land 29.5% ATK each at level 1 and 82.0% at level 10, with the fourth at 59.1% rising to 165.0%. Megaphone's first three strikes run 22.5% to 63.0% and its fourth 60.0% to 167.0%. Her second skill, Luminous Leaper, still has no description exported on the community wiki as of August 3, so the kit is not fully public.
The banner card shows two further rate-up portraits beside her under "Higher chance for these Trekkers!!". Neither name is legible in the asset and no source publishes them, so they stay unnamed here.
Fleeting Glimmers is built around exactly one kind of Trekker
The disc banner "Rippling Waves, A Touch so Gentle" runs the same July 20 to August 10, 19:59 UTC-7 window as the character banner. Its featured 5-star is the Aqua Runic Disc Fleeting Glimmers, named on the update preview rather than on the banner art itself.
The Melody Skill grants the squad 20% to 40% Aqua DMG across its six ranks. When an Aqua Support Trekker casts a skill, or every 5 seconds they spend on field, the squad gains Tide Weave for 6 seconds, stacking to 4. A Tide Weave holder inflicting Aqua Mark adds 15% to 30% Aqua Skill DMG Taken on the target for 4 seconds.
Both Harmony Skills push the same lever. Azure Echo gives Aqua Trekkers 12% to 28% Crit DMG and adds 10% to 30% Aqua Auto Attack DMG Taken off a Tide Weave holder's Aqua Mark. Sun-Kissed Sands converts each Tide Weave stack into 2% to 10% own Aqua DMG and 2% to 10% ATK for Aqua Support Trekkers, then refunds 1.5% to 7.5% Max Energy per stack after an Aqua Support Ultimate, capped at 20 to 85. Suntide Willow is the Aqua Support the whole disc is written for (T2, community wiki).
20 free pulls, not 21
The log-in event "Setting Sail for A Rippling Summer" pays Suntide Limited Ticket ×20 and Drop of Purity ×1 between July 20 and August 10 at 19:59 UTC-7. GameMarket.gg counts that as 21 free pulls. It is 20.
Drop of Purity is an Emblem Material, rarity 5, used to Temper Emblem affixes up to a cap of two tempered affixes per Emblem (T2, community wiki item 35010). It is gear currency, not recruitment currency, and it buys no pull on any banner.
Whether the 20 tickets are hard-locked to the limited banner is unverified. The item is called Suntide Limited Ticket, which points that way, but no official text states the restriction.
Two beta modes, and they run on different calendars
Through Hostile Depths is the board strategy mode. Its card puts chess pieces on a board floor under a shadow-king silhouette and opens with "Tyrant, take your place on the board as a strategist, rally your finest champions, and seize victory from the very first move!" It paid Drop of Purity, Star Emblem Polisher and Emblem Enhancement Materials, and it closed with the main event on August 3 at 12:59 UTC-7.
Operation: Shadow Siege is the hunt commission board, and it is the one still open. Its card is a corkboard of targets pinned with red string: Mountainous Space Walker, Enforcer of Silence and Fanged Hunter: Radiance. Rewards are Zesty Curiosity, Seasonal Waves, Silver Disc, Star Emblem Polisher and Emblem Enhancement Materials. It runs to August 31 at 12:59 UTC-7, three weeks past everything else in the patch.
Exactly two 3D appearances ship in 1.13
Iris gets "Drifting Together on Gentle Waves", listed on the preview card as Purchase in Shop, from July 20 after maintenance to August 17 at 19:59 UTC-7. That is the longest single window in the patch and the only paid cosmetic in it.
The second is a rerun: Nazuka's "A Dip of Fresh Summer", back after August 3 at 21:00 UTC-7. That is the complete list. There is no free appearance in Version 1.13, no event-earned appearance, and no yukata or festival outfit set in the game.
The August 3 wave: Nazuka, Deer's Song and a one-week shovel
After August 3 at 21:00 UTC-7 the patch reloads. The 5-star Trekker Nazuka returns on "A Breezy Romance", her first run since December 08 to December 29, 2025 (T3, banner timeline). The 5-star Runic Disc Deer's Song returns on "Afternoon Glimmer into the Green", her appearance rerun opens alongside, and the event A Finale Echoing opens in the same window.
Lucky Treasure Shovel is the only new event of the second half with a full stamp: August 3 at 21:00 to August 10 at 12:59 UTC-7. It pays Star Emblem Polisher, an Exquisite Gift Box and a Monolith Stairs Pass.
The rerun wave overlaps the tail of the Suntide Willow banner by 6 days, 22 hours and 59 minutes. Close to a week, and short of one.
August 10: Chapter 8 and two refreshes
Main Story Chapter 8, "Lingering Warmth", opens August 10 at 21:00 UTC-7 after maintenance, permanent. Its key art puts five characters in frame with one collapsed on the ground.
Two refreshes land the same day on different clocks: Urgent Bounty after 13:00 UTC-7, Call for Best Records after 21:00 UTC-7. Both stamps come from the official preview card.
Three codes live, none with a published expiry
| Code | Reward | Expiry |
|---|---|---|
CLAW2026 | not specified by any source | unpublished |
2025XMAS | not specified by any source | unpublished |
BOSSGIFT | 100 Stellarite Dust | unpublished |
No 1.13-specific code exists. Sources disagree on whether BOSSGIFT's currency is spelled Stellarite or Stellanite; the amount, 100, is consistent. Redeem on the official redemption site with the UID from your profile, and the rewards arrive by in-game mail. Tier is T3: the two code trackers carrying these were last updated on August 2, 2026 and January 31, 2026.
Because no expiry is published for any of the three, an old code can die silently between checks. Redeem before you need the currency, not after.
The swimsuit art is Comiket merchandise, not skins
Yostar exhibits at Comiket 108 on corporate booth No. 1111, August 15 (Saturday) and 16 (Sunday), 2026, in Tokyo Big Sight West Exhibition Hall 3. The venue-limited Stella Sora merchandise there is built on newly drawn illustrations, 描き下ろしイラスト.
Two illustration sets have been revealed: a swimwear group holding water guns, and a six-character yukata set with festival props. Both circulated widely as "1.13 summer skins". Neither is in-game content, neither is purchasable in the shop, and neither corresponds to a 3D appearance.
Three dated things decide where 1.13 lands
Whether Through Hostile Depths comes back. It closed on August 3 at 12:59 UTC-7 with the beta tag still attached and no return window published anywhere.
Whether Operation: Shadow Siege survives August 31 at 12:59 UTC-7. It is the only 1.13 mode built to outlive its patch, and the only one whose beta label will have run 42 days.
What Chapter 8 does on August 10 at 21:00 UTC-7. It is the patch's one piece of permanent content, and it lands 1 hour 1 minute after the Suntide Willow banner closes. We will update this piece as each of the three resolves.
