One of the Extras of Kamen Rider Ex-Aid's Summer Movie who had attended the Filming today had uploaded the Script's Cover and it revealed the temporary title of the movie. The temporary title of the movie is "Kamen Rider Ex-Aid: True Ending".
The title of the movie is "Kamen Rider Ex-Aid: True Ending". A month ago during Kamen Rider Snipe: Episode Zero's Talk Show, Kamen Rider Ex-Aid's Producer Takahito Oomori had actually mentioned it to be True Ending of Kamen Rider Ex-Aid but I never thought he literally meant that.
P.S. I had translated it as "this movie which is almost near to the True Ending of Kamen Rider Ex-Aid" assuming that Takahito Oomori meant like this but after seeing the title I think I assumed it wrong.
