Miki drops a strange bell-shaped object, and a school friend picks it up. On the bus ride home the brakes give out, and the bus rolls into a long dark tunnel that carries both girls into another world. When Miki comes to, she watches wolf-faced warriors seize her friend, apparently mistaking her for the girl with the bell. Miki tries to follow and rescue her but fails, and she is left stranded in a land of monsters and madmen who are plotting Earth's ruin. Her one hope, and the world's, lies in a mysterious talisman called the Mask of Zeguy. She sets out on a perilous search for it while the villains chase her. The two-episode OVA mixes action, adventure and fantasy.
