Aside from the film's story and a new trailer, it is confirmed that ISSA, who originally performed Kamen Rider 555's opening theme, will perform the film's theme song, "Identiφ's", which also feature a chorus from m.c.A・T, another artist that performed insert songs for the show. The song is set for a February 2, 2024 release.
The Regular and Special Editions are both set for a May 29, 2024 release, and Complete Selection Modification Kaixa Phone XX and Complete Editions are both set for a September 13, 2024 release. Toei Video has the breakdown of the differences in each set, but to summarize, all the contents included in the Blu-ray and DVD release are included in the Complete edition. If you only wants a physical copy of the film with barely any special features, get the Regular edition; with the bonus disc filled with special features and the theme song CD, get the Special edition. If you only want the the movie and the CSM Kaixa Phone XX, get the CSM Kaixa Phone XX edition.
