Story

The devil Sword and the angel Ios are fighting their 100th battle during one of the many wars between angels and devils, when, both severely wounded, they fall on Earth, where each of them has to take the body of a human to survive; to their astonishment, the bodies they take are those of two twins, and, to make things worse, the angel has taken the body of the violent and rebel Kanna, while the demon has taken that of the weak and defenseless Soma. They can't use their powers, so they have to cope with being human brothers. But being without powers doesn't mean they don't have to fight, because creatures from Hell start appearing in this world, and most of them seem to be looking for the fallen demon Sword...
