Just Breed (ジャストブリード Jasuto Burīdo?) is a tactical role-playing game published by Enix for the Family Computer. It was released exclusively in Japan in 1992. Although it is somewhat obscure and was overlooked due to its late release, it is notable for its long development and as one of the largest RPGs created for the Family Computer.
The game's story opens in the town of Astholm, which is spiritually protected by a sapphire wielded by the priestess Firis. She is one of six priestesses charged with holding a special gem to have together held an archaic power for several generations. During the town's Sapphire Festival, Firis is kidnapped by the henchman of Ezelkiel, a man bent on collecting the priestesses to revive an ancient evil. The player takes on the role of the nameless Hero who, along with being sworn to protect Astholm, is the lover of Firis. He immediately sets out with his army to rescue the priestess and ends up becoming involved in a much larger-scale predicament involving the world's other priestesses and gems.
