Oh! My Goddess 11. Der Kampf um Urd

Life can get stressful for a mortal male when he lives with three gorgeous goddesses, and so the group take off to a hot spring resort for a little quality down time. But when the delectable demon Mara-who's had some unpleasant run-ins with the goddesses -appears and hooks up in the bar with her old drinking buddy, the goddess Urd (who's half demon herself), matters take a supernatural turn for the worst. Instead of burying the hatchet, Mara is out to bury the goddesses with the help of a 100% purely demonic clone of Urd! So much for stress reduction!
