Yoroiden Samurai Troopers

A thousand years ago, a very powerful demon who wished to possess the world, Arkatakor (Arago in the original version), was defeated by a warrior accompanied by a white tiger, and sent back to his own world. But his armor had remained in the human world. The warrior, then becoming a monk and using mystical powers, separated the armor into nine new armors, each possessing a virtue.

The remaining five are in the hands of five young boys who will then do everything to defeat the demon Arkatakor once again...
