This is an era of division between the holy and the evil
Three million years ago, the War Sword Group that protects the world split into two opposing organizations - the Holy Sword Group and the Evil Sword Group. The Holy Sword Group believes that protecting mankind is the way to save the world, while the Evil Sword Group believes that destroying mankind and re-creating an environment is the way to protect the world. The two sides fought until 2138. It was during this incident that an original swordsman without elements was born.
