Sengoku Rider War

The Sengoku Rider War is the war between the Armored Riders and the Inves. Taking place in a terrible future where the Helheim Forest has taken over the world.

This predestined war starts with Gaim and Baron's factions (with Gridon and the other Suika Arms Armored Riders behind him) were ready to war, while Zangetsu's faction (with Ryugen near him) are watching the pre-fight as the mysterious woman with a white dress awakens and accidentally dropped her Lockseed flower hair decoration as Gaim and Baron's factions charged at each other.
