Season III Announcement and Teaser Visual

Iska and Rin Return to the Empire

Season II ended with Sisbell being taken toward the Empire amid the upheaval inside the Nebulis Sovereignty. Alice then ordered Rin to work with Iska and Unit N07 to rescue her younger sister.

Season III follows that operation into Imperial territory, where the group encounters research connected to the creation of an unknown “true witch.”

Alice Faces the Awakening of Founder Nebulis

While Iska and Rin move into the Empire, Alice remains in the Sovereignty as acting queen and monitors the Zoa and Hydra families.

Her situation changes when Founder Nebulis, sleeping beneath the royal palace, begins to awaken. That development pulls Alice toward another conflict while the hidden history of the two nations starts coming into view.

A Century-Old Secret Moves to the Center

The official introduction says Season III will uncover previously unknown history involving the Empire and the Nebulis Sovereignty.

Elletear also begins moving again with her own objective, while encounters with events from a century ago push Iska and Alice closer to what the story describes as their true destiny.

Original author Kei Sazane says the new season will feature a larger-scale story and episodes that approach the core of the series.

Main Staff and Cast Return

Season III retains the core production team from Season II. Yuki Inaba returns as both director and series composer, with Kaori Yoshikawa continuing as character designer.

Animation is again handled by studio Palette × SILVER LINK., while Yusuke Kobayashi, Sora Amamiya, Yumiri Hanamori, Azumi Waki, and the other principal cast members return.

Why This Matters

1) Season III immediately continues the unresolved mission

The story moves directly into the operation to recover Sisbell rather than resetting the conflict.

2) The history of both nations becomes central

The next season will move beyond present-day political clashes and explore the hidden past connecting the Empire and Sovereignty.

3) The main Season II team remains intact

The director, series composition, character designer, animation studios, and principal cast are all returning.

4) The broadcast schedule remains completely open

Production has been announced, but no year or seasonal window has been confirmed.
