Kamen Rider Brave ~Let's Survive! Revival of the Beast Rider Squad!~ (仮面ライダーブレイブ ~Surviveせよ! 復活のビーストライダー·スクワッド~,Kamen Raidā Bureibu ~Sabaibu Seyo! Fukkatsu no Bīsuto Raidā·Sukuwaddo~) is a Toei Tokusatsu Fan Club-exclusive special of Kamen Rider Ex-Aid. A 7-minute preview of this special was uploaded onto Toei's official YouTube channel for Japanese viewers only.
A group of revived beast-themed Riders gather to form the "Beast Rider Squad"... and Kamen Rider Ouja, the worst villain Rider, is leading them! Can Kamen Rider Brave hunt them with his new Gashat, "Night of Safari"? And what is the secret behind this battle?
Additionally, the special's title contains the word "Survive", an important theme in Ryuki, being the name of its primary Rider Power-Up form and part of the season's tagline, "If you don't fight, you won't survive." Asakura himself even said to Hiiro that "if you don't fight, you will die."
The scene where Asakura eats mackerel fish is a reference to Choukou Senshi Changéríon episode 10 This Isn't Mackerel! (サバじゃねぇ！,Saba Ja Nee!), which is a popular meme in Japan.
The main hero of this show, Changéríon, was also played by the same actor as Asakura.
Ouja using Sasword and Beast as a shield to defend himself from Brave Level 4's attack is a callback to episode 19 of Ryuki, where Ouja uses Kamen Rider Gai as a shield to defend himself from Zolda's Final Vent.
There are several references to horror movies in this special:
When Mizuki is attacked while taking a shower, the scene is an obvious homage to a scene with the same motif in the film Psycho, however, the way the Rider attacks her is more similar to how Freddy Krueger operates.
Additionally, the way Ouja stalks and preys on his victims is similar to the modus operandi of killers from slasher films such as Jason or Leatherface.
