Meet Otoha: The New 5-star Trekker

The spotlight of this event is Otoha, a limited 5-star Umbra‑Element Versatile Trekker. A mysterious ninja who hides a blade within her parasol, Otoha excels both as a main damage dealer and a support unit. She enhances Umbra allies’ damage output while delivering devastating AoE strikes, making her a must‑have for Umbra‑focused teams.

New 5-star Disc: Petals of Blooming Mirage

Alongside Otoha, the event also introduces the 5-star Disc “Petals of Blooming Mirage”, designed to strengthen Umbra‑Element squads. Its haunting melody evokes a dreamlike sea of flowers, tying into Otoha’s story and adding depth to team compositions.

Stella Sora Gameplay Expansions

Several new gameplay modes will roll out during the event, including:

• Fatebound Stellar Deck
• Summit Show
• A Finale Echoing (high‑difficulty challenge)

Additionally, the Ascension mode now features Difficulty Level 8 and new Monolith Research nodes, offering fresh challenges for veteran players.

• Emblem Tempering: Enhance Affix effects using the new item Drop of Purity.
