Oh My Goddess! Vol 14

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! Get a job! That's what you hope a college education can do for you - but when Keiichi applies to put his knowledge to work in a custom-bike shop, he finds it's not going to be as easy to graduate college as he thought! And it could be that no one's leaving Nekomi Tech ever again, when it falls under the mind-bending influence of two of the most sinister forces known to man: Mara's magic and Sayoko's ego!
