And then, hundreds of million nights had gone. The king of the abyss was laid up. He tried with his last power, and gave birth to two hopes. The red prince was born from his right eye, and the blue prince was another one. The future is always only one."
Apocripha/0 takes place in a "devil's point of view," in a world known as "Naraku." Since devils live here, in vice versa, angels from 'heaven' are their enemies.
