In the process, however, they encounter a real, human burglar and crack an unresolved case connected with a "cursed" wisteria tree.

Karin is an underperforming klutz - until a ring left to her by her recently dead mother becomes a sort of talisman and turns her into a magical girl with incredible powers! Of course, there's a rude boy and some very bad guys involved, too, along with the usual requisite dose of utterly disarming Koge-Donbo cuteness!

As if the problems of being a little goddess weren't enough, Karin is struggling in school. She has to raise her grade on the next test or she'll be expelled! Fortunately, she gets some help from her crush, Kirika-senpai. Kazune seems jealous when he raises suspicions about Kirika, but before he has much time to complain, he is attacked by their archenemy, Kirio!

After prancing around in a sumo suit all day, Karin (against Kazune's wishes) dances the night away with Kirika at a bonfire. He makes her swoon and secretly takes her ring. Karin, in search of her ring, finds out Himeka has a crush. A trip to the hot springs boils into a heated competition between Kazune and Kirio! Kazune pleads with Michiru to keep his secret away from Karin. What could his secret be? Kirio's ring starts to act weird, so Kazune knows something is up...

Still on their hot springs vacation, Kazune and Karin face off against Kirio... but when they change into god form, they're in for a big surprise! Meanwhile, Karin continues to wrestle with her feelings for Kirika. In some ways he seems like her perfect knight in shining armor, but there's definitely something different about him...

The School Art Festival approaches, and several secrets are divulged as an attack exposes Kirika's true identity and Karin sees a family portrait in a new light. Is Kazune endangering himself if he continues to transform the way he does? And when Michiru and Karin share a misplaced moment, what will happen to their relationship?!

Kazune decides to continue to transform so he can protect Himeka, and when Karin proposes that Michiru help, he surprises them both by volunteering himself! Later, with the help of Michiru's friend, they are given information regarding transformations, rings and Himeka's health.

Karin's tender loving care wakes Kazune from a coma. A confused Kazune feels Karin is hiding something from him. It seems this troubled soul has yet one more task to do before he will have some peace. If Kazune can avoid trouble long enough, will he uncover why Karin is being so nice to him?
