Kamichama Karin Chu Vol 1

From the Del Rey Manga edition

Karin's your loveable girl-next-door type - if the girl next door also happens to be a goddess! Karin has a magic ring that gives her the power to do anything she'd like. What she'd like most, though, is to live happily ever after with Kazune, the boy of her dreams. Magic brought Kazune to her, but it also has a way of complicating things. It's not easy to be a goddess and a girl in love.
