The Ronin Warriors Message revolves around a 300-year-old book containing the stories of the Samurai Troopers. However, this chronicle is written centuries before the Troopers' actual adventures take place, raising questions about the nature of their existence. Suzunagi, a girl with unclear intentions, becomes involved with the warriors, offering each of them something they desire – salvation, new armor, or freedom from their duties – without explicitly revealing her motivations.
