Karin Hanazono is an ordinary 13-year-old girl who becomes depressed after the death of her parents and her last companion, her pet cat Shii-chan. With poor grades, a mean aunt, and few friends who understand her, she feels lonely and desperately believes that God will help her out of these circumstances one day, holding on to the last remaining momento: a ring that originally belonged to her mother. Things change for better for Karin when she meets Himeka Kujyou and her cousin Kazune, whom she lives with. A confrontation after Kazune insults Karin's cat and ultimately her feelings invoke something within her and the ring, causing everything to go smoothly for Karin, including weather matters. It turns out that her precious ring is in fact a holder of the power of God, and Karin, as its bearer, is a goddess. With this revelation, she is hunted down by mysterious enemies who are seeking that power while trying to control her strength. On her journey, she discovers more about her past, and the truth of her goddess heritage, as well as how it affects others around her like Kazune and Himeka.
