Dragon (Kamen Rider: Echo Demon)

The Dragon is the most powerful of the Makamou, & was last seen in the Waring States Era. With the aid of its Parents, the Dragon eats an ideal maiden once a year, forcing the villagers to sacrifice their daughter to quell the Makamou's wrath when its castle raises from the sea. Though its fate was never revealed, the Dragon was defeated by the Oni when the first Echo Demon used the Armed Saber to fight it.

Another Dragon appeared in modern times, attacking people at a beach & hospitalizing Echo Demon. But Josh researched the "Warring States Dragon" event & managed to find the Armed Saber for Echo Demon to use as his predecessor had, killing the Dragon as Echo Demon in Armed Form with the Sound Attack Blade: Fierce Demon Arousal.

Prince & Princess
These two appeared during the Feudal era, prior to the formation of FIERCE when they oversee a Dragon whose care they are entrusted with. Prince & Princess wore attire of feudal era mistress & samurai with broken demon masks on their faces, able to fly like Will-o'-the-wisps & use pyrokinesis. They were killed both by the Oni.
