Keiichi awakens from a nightmare in which a hideous demon threatens to transform him. Belldandy, however, isn't sure that it was just a dream. Sure enough, Tamiya encounters a strangely compelling compact disk, and he buys it, forgetting that he doesn't even own a CD player! Unfortunately, all it needs to summon forth the demon Mara is a spin on an old record player, and Mara's ready to wreak havoc on old enemies Belldandy and Urd -- through the hapless Keiichi!
