Oh My Goddess! Vol 12

From the Dark Horse edition

Ever since a cosmic phone call brought the literal young goddess Belldandy into college student Keiichi's residence, his personal life has been turned upside down, sideways, and sometimes even into strange dimensions! Maybe you think Peorth couldn't cause any more trouble -- well, think again! Determined to provide Keiichi 'better service' than Belldandy, she's dragging him out on a date -- having studied human mating customs through shojo manga! But what is the secret slight that truly drives Peorth's efforts against her rival?
