- Hey, It's That Guy!: In the live-action version, Gennosuke is played by Joe Odagiri, who is no stranger to the superhero genre. And Oboro is no stranger to being an authority figure to violent misfits.
- Playing Against Type: The murderous Hotarubi is played by Miyuki Sawashiro, who usually voices Genki Girls and Moe types. Then again, Hotarubi acts like one if you don't mess with her beloved Yashamaru.
