Star Detective Precure! Movie Trailer Brings Three Precure Teams Together Before September 18 Release

Star Detective Precure! The Movie: The Mysterious Garden and the Secret of the Two gets two new trailers on the same day, and together they confirm something bigger than a normal Precure movie push: three separate Precure generations are appearing on screen together ahead of the film’s September 18, 2026 Japanese release.

What’s Confirmed

• Official title: Star Detective Precure! The Movie: The Mysterious Garden and the Secret of the Two (映画名探偵プリキュア！不思議な庭と2人の秘密)
• Japanese theatrical release: September 18, 2026
• Two new trailers released the same day: “KimiPri & WanPri Edition” (キミプリ＆わんぷり篇) and “This Is a Great Detective! Edition” (これぞ名探偵！篇)
• The “This Is a Great Detective!” trailer is confirmed via official YouTube upload from Precure’s official channel (youtube.com/@precure)
• Confirmed appearing: the four Star Detective Precure leads — Cure Answer, Cure Mystique, Cure Eclair, and Cure Arcana — alongside characters from You and Idol Precure♪ (including Cure Idol) and Wonderful Precure! (including Cure Wonderful)
• The film’s threat is the “Dame-Dame” — small creatures tied to the ongoing “X-Mark Incident” the Detective Precures are investigating
• A fairy named Rain leads the team to a location called “Karin’s Garden,” which the Dame-Dame have overrun
• The “This Is a Great Detective!” trailer includes Future Form transformations for all four main Star Detective Precure characters
• New character visuals and voice-cast comments from both the You and Idol Precure and Wonderful Precure casts were released alongside the trailers

A second trailer, “KimiPri & WanPri Edition,” was released the same day and is described in Japanese entertainment coverage as revealing that the You and Idol Precure and Wonderful Precure casts — not just the Star Detective Precure leads — were independently investigating the Dame-Dame mystery. This piece links to that coverage rather than embedding the video directly, since its YouTube listing currently has embedding disabled and its official channel/upload details couldn’t be independently confirmed the same way as the trailer above.

Which Teams Are Actually Confirmed vs. Just Visible

Be precise about what’s locked in here: Toei’s own materials and the accompanying voice-cast comments confirm named appearances from Cure Idol (You and Idol Precure♪) and Cure Wonderful (Wonderful Precure!), alongside the Star Detective Precure quartet. Japanese coverage also describes “past-generation Precures” appearing in quick succession in the crossover trailer — that’s a real, sourced claim, but it doesn’t come with a name-by-name list of every legacy character shown. Treat “Cure Idol and Cure Wonderful confirmed, plus a broader legacy-Precure cameo sequence” as the accurate summary, rather than assuming every past Precure gets a speaking role.

The Dame-Dame and Karin’s Garden Setup

The confirmed plot hook: the Star Detective Precures are investigating the X-Mark Incident when a fairy named Rain asks for their help, leading them to Karin’s Garden — a location now overrun by the small Dame-Dame creatures. That’s the extent of what’s been officially laid out. Neither trailer nor the accompanying press material spells out why the crossover teams get pulled in, what Karin’s Garden actually is beyond its name, or how the Dame-Dame connect to the film’s antagonist beyond being the visible threat.

Future Forms Aren’t New Information

The “This Is a Great Detective!” trailer features Future Form transformations for the four Star Detective Precure leads, but these were already revealed prior to this specific trailer push — their appearance here is a re-confirmation and showcase, not a new reveal. Don’t read this trailer as the first time Future Forms have been shown.

International Release Status

Nothing here should be assumed: no official international theatrical release, streaming date, or dub/sub distribution plan has been announced for Star Detective Precure! The Movie at the time of writing. The confirmed release is Japan-only, September 18, 2026.

What’s Still Unknown

Beyond the broad Dame-Dame/Karin’s Garden setup, the film’s full plot, how the three Precure generations’ stories actually intersect beyond appearing together, and any additional cast or character reveals remain unconfirmed ahead of release. Treat trailer editing and quick-cut cameos as marketing, not a scene-by-scene preview of the movie itself.

Bottom Line

Two new trailers confirm a genuine three-generation Precure crossover ahead of the September 18 release: Star Detective Precure’s own cast investigating the Dame-Dame threat at Karin’s Garden, joined by confirmed appearances from Cure Idol and Cure Wonderful representing two prior series. Future Forms return rather than debut here, and no international release has been set.
