The land of Junovald was shaped by two opposing gods—Meitilia, who governs death and destruction, and Formival, who governs life and creation. The creatures native to Junovald, called Belzeds, can only be killed by combining the talents of two different types of warriors: a Blade, who destroys the body, and a Sealer, who destroys the soul. Without both working together, a Belzed simply reforms. Last Rebellion is an RPG built around this mechanic: two protagonists, one a Blade and one a Sealer, sharing the same body and trading control depending on what the situation requires.
