Sentouin D

戦闘員D

He is a rebellious foot soldier from the villainous army stationed in the sky fortress that arrived 13 years ago. As a Duster, he possesses transformative and regeneration abilities, just like his fellow foot soldiers, who have vowed to defeat the Dragon Keepers by infiltrating their organization and ranks. For most of the series, he assumes two disguises: one resembling an average teenage guy with black hair, and the other as Hibiki, allowing him to use that identity to infiltrate their ranks more easily.
