A 300-year-old book is discovered which chronicles the adventures of the legendary Samurai Troopers… centuries before they happen! But what does this mean? Are the Troopers merely puppets in some cosmic play, acting out parts? Who is this mysterious Suzunagi, a mysterious girl who entices each of the warriors with their hearts’ desire - salvation, new armors, freedom from a life of fighting. Why is she so interested in the troopers and their armors? (Source: AniDB)

A strange, silent warrior appears. When the Inferno armor is summoned to battle him, the mysterious warrior calls forth his own armor—a black copy of the Inferno armor! Now, the warriors will find themselves half a world away fighting once more to save humanity, but this time, from their own armor!

Thousands of years ago, the evil emperor Talpa attempted to conquer the Earth. Defeated, he was banished to the Nether Realm and his armor was divided into 9 separate suits. Now, he has returned to conquer Earth, having reclaimed 4 of the suits. The other 5 are in the possesion of those who are the only hope of stopping him: The Ronin Warriors.
