Trivia / Kamen Rider BLACK SUN

• Reality Subtext: One of the last scenes of the series is the Prime Minister being decapitated by a kaijin's lariat, immediately after taking a piss on a pro-kaijin memorial. Not exactly like being assassinated in broad daylight with a scrap-made firearm, but still close enough to recent events.
• What Could Have Been: Bishum originally was planned to be an Peacock Kaijin in concept art, but this was rejected in favor of having her be the Pterosaur Kaijin much like the original Bishum's Grand Mutant form.
