What’s Next for Part 2?
While Part 2 doesn’t yet have a confirmed release date, Ufotable may drop details during Jump Festa 2026, scheduled for December 20–21, 2025.(m.economictimes.com)
This aligns with the pattern of major announcements at Annual Jump-related events, creating buzz at the right moment.
Why These Dates Matter: Context and Strategy
- Annual Rhythm Maintained: Following a cadence similar to past arcs, the trilogy’s rollout continues the pattern of yearly content drops—from TV seasons to films.(us.oricon-group.com)

- Global Synchronization: The completion of the theatrical run before streaming preserves box office momentum while giving fans worldwide a special cinematic experience.
“The international release schedule demonstrates that anime’s appeal has finally broken the glass ceiling of mainstream cinema.”
That reflects the confidence and cultural weight the franchise now commands.
