Following the death of her beloved cat, orphan Karin Hanazono is left feeling lonely and empty. Since she has no friends and performs poorly at school, her mean-spirited aunt resents having to take care of her. Wholeheartedly believing that God will grant her salvation one day, she tightly holds onto the ring that her mother passed down to her. Seeking solace by spending time at her late cat's grave, Karin unexpectedly meets a boy named Kazune Kuujou, who claims he is looking for God. However, Kazune calls her weak for relying on her deceased cat for comfort. Angered by the insult, Karin subconsciously channels energy into her mother's ring. Soon enough, she begins to excel at school and classmates compliment her for the first time. Unbeknownst to her, the ring has bestowed her godly powers. The revelation of the ring's transcendent strength catches the eyes of not only Kazune but also more sinister figures who wish to take advantage of Karin for nefarious purposes. Karin must now use her newly acquired gift to fight back against these malicious forces, unaware of the truth behind her heritage and the existence of others with similar abilities.
