This special features 2 Ryuki Riders, Ouja and Tiger. Interestingly, this year marks the 15th anniversary since the premiere of Kamen Rider Ryuki (2002).
While Takashi Hagino previously reprised his role in a voice-only capacity in Kamen Rider Decade (2009), this marks the first in-the-flesh appearance of Takeshi Asakura since the conclusion of Kamen Rider Ryuki (2002).
According to her hospital placard, Satsuki's full name is Oogimachi Satsuki and is blood type A. She was hospitalized February 20th, which is a day after the Brave special was released.
The special's title contains the word "Survive", an important theme in Kamen Rider Ryuki (2002), 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."
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 from Psycho (1960), 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 from the Friday the 13th film series or Leatherface from The Texas Chain Saw Massacre (1974).
