Toei had finally announced the titles of all three Kiramager, Ryusoulger and Zenkaiger THE MOVIEs. Though we knew the title of Kiramager THE MOVIE → Mashin Sentai Kiramager THE MOVIE: Be-Bop Dream, but this is the official announcement from Toei this time.
When it comes to Ryusoulger THE MOVIE, it's titled as Kishiryu Sentai Ryusoulger Special: Memory of Soulmates. It looks back at the untold story of Nada because his death in the TV Series.
After the return of Kamen Rider Amazons stars → Masashi Taniguchi & Rena Takeda in the Kamen Rider Saber Short Film and RIDER TIME: Kamen Rider Decade Vs Zi-O / Kamen Rider Zi-O Vs Decade, we are going to get the return of another Amazons star → Kanon Miyahara.
She is going to play the role of Maiko who will get kidnapped by Kleon. She is also the key person of the movie.
By the way, you do realize that she had now appeared in all three Ultraman, Kamen Rider & Super Sentai and that is also before Kamen Rider Amazon Alpha → Masashi Taniguchi & Ultraman Dyna → Takeshi Tsuruno.
Zenkaiger's part will be a little bit funny. The title of the movie is Kikai Sentai Zenkaiger THE MOVIE: Red Fight! All Sentai Big Gathering!!. Just as the title we are going to see the return of All Sentai Red from Gorenger till Kiramager and among them we have white coloured Zenkaiser. Even Akarenger is surprised and questions him "So aren't you Red?".
When it comes to the story, it looks like Kaito (Zenkaiser) & the Kikainoids were planning for Pizza, Sukiyaki Party and they are kidnapped by the past Sentai Villains. We also get to see Basco ta Jolokia confronting Kaito. It's not yet known whether Kei Hosogai is going to voice reprise this role.
