Stella Sora’s Version 1.15 went live after the September 7, 2026 maintenance. The headline is ★5 Limited Ventus Trekker Eleanor, but the quieter addition is a To-Do List that finally puts the rotation of every permanent mode on one screen.
Maintenance Compensation
Maintenance ran from Sep. 07, 2026 20:00 to Sep. 08, 2026 02:00 (UTC-7). Players who registered and created a character before it began receive Stellanite Dust ×450 and Bottled Vigor Soda ×1 by in-game mail, sent within an hour of the servers returning. The mail stays valid until Sep. 14, 12:59 (UTC-7). The Vigor Soda’s own expiry runs from when you claim it, to 12:59 on the Monday of the second week after.
New Banners
- ★5 Limited Ventus Trekker: Eleanor is recruited from With Graceful Steps Elegance Arrives.
- ★5 Limited Ventus Disc: Fly, O Caged Bird is recruited from Toward Her Heart’s Desire.
Both run to Sep. 28, 19:59 (UTC-7), and the rates and the 120-recruitment guarantee are worth reading before spending.

The story picks up the young lady chasing her dream behind her family’s back, until a sudden disappearance forces her forward.

The shop stays open a week longer than the event that fills it, so the Paper Stars can be earned to the 21st and spent to the 28th.
