Chained Soldier Season 3: What's Confirmed and When It Could Air

Chained Soldier Season 3 is officially confirmed. The third season of the anime, based on the manga Mato Seihei no Slave, was announced on August 2, 2026, less than five months after Season 2 finished airing. There is no premiere date yet, and the studio and staff for the new season have not been named.

This is an early "adaptation confirmed" beat: fans can bookmark it, but should not expect episodes in 2026. Below is the short version of what was actually revealed versus what remains unknown, plus what collectors of action-shonen figures can do in the meantime.

What is confirmed about Chained Soldier Season 3

The announcement was made at a live Chained Soldier event in Japan on August 2, 2026, and came with an announcement key visual, a short teaser video, and comments from the returning cast. That is the extent of the hard information Pony Canyon and the production released.

Chained Soldier is the English title of Mato Seihei no Slave, a manga written by Takahiro and illustrated by Yohei Takemura that has run on Shueisha's Shonen Jump+ platform since 2019. The story is set in a near-future Japan where portals to a hostile dimension called Mato have opened, and a Mato Defense Force of superpowered women is formed to fight the monsters inside. It follows Yuuki Wakura, an ordinary young man who stumbles into Mato and is rescued by elite officer Kyouka Uzen.

Why the studio question matters this time

Chained Soldier has already changed hands once. Season 1 was produced by Seven Arcs and aired from January 4 to March 21, 2024. Season 2 moved to Passione and Hayabusa Film under director Masafumi Tamura, with character designs by Keiya Nakano and music by Kohta Yamamoto, and aired from January 8 to March 26, 2026.

Because the Season 3 reveal named no studio, director, or staff, it is safest to treat the project as freshly greenlit rather than deep in production. That distinction is what tells collectors how soon to expect a new merchandise wave: prototype figures and Ichiban Kuji lineups typically follow a broadcast window, not a bare announcement.

When could Chained Soldier Season 3 air?

No release window has been confirmed. Given that no studio or staff have been announced, a 2027 premiere is the optimistic case and a later date is entirely possible. Season 2 was itself announced well ahead of its January 2026 broadcast, so a similar gap here would point past 2026.

A few quick answers to the questions fans are searching right now:

• Is Season 3 officially confirmed? Yes, as of August 2, 2026.
• Is there a release date? No. Only a key visual and teaser exist so far.
• Where can I watch the earlier seasons? Season 2 streams on HIDIVE, with MUSE and Aniplus carrying it in other regions.
• Will the studio change again? Unknown. Season 3 has not confirmed a studio.

What collectors can do now

Chained Soldier does not yet have its own figure line to chase, so the practical move is to expect merch to arrive closer to broadcast and to keep an eye on prototype reveals once a studio is named. Until then, fans of its action-and-supernatural mix tend to collect in the same lane as other Shonen Jump action titles.

If that describes your shelf, the in-stock Jujutsu Kaisen figures at Akibato sit in the same collector space and ship worldwide, so you can build the display now rather than wait for a Mato Defense Force wave that has no announced date. We ship from Japan directly to overseas collectors.

Key takeaways

• Chained Soldier Season 3 was officially confirmed on August 2, 2026.
• Only a key visual, a teaser video, and cast comments were revealed.
• No premiere date, studio, or staff have been announced.
• The series has already switched studios once, from Seven Arcs to Passione and Hayabusa Film.
• A dedicated figure wave is unlikely before a broadcast window is set.
