Milestone anniversaries are something that rarely go uncelebrated in the Kamen Rider franchise, and when it's a series as popular as Kamen Rider 555 of course something big was going to happen for its 20th birthday. Though a series that has continued to endure in parallel universe, crossover and/or spin-off material, there is one thing that it has constantly been denied - a proper resolution. All this could change however with the release of Kamen Rider 555 20th: Paradise Regained, a V-Cinext reunion film penned by original writer Toshiki Inoue (fresh off his work on Avataro Sentai Donbrothers) and directed by Ryuta Tasaki (who has worked on nearly every Kamen Rider series since Agito). The film's production was initially announced on the 5th May 2023, which was dubbed "Faiz Day" in celebration of the 20th anniversary.
