You are an orphan with nothing, and then a boy tells you that you're actually a goddess, and suddenly you have to save the world before you've even saved yourself. The comedy comes from Karin being genuinely terrible at everything, at being a magical girl, at school, at understanding why this is happening to her, and the show never punishes her for it. What makes this different from every other magical girl show is that Karin's power doesn't fix her life; it just gives her a reason to keep trying anyway, and that's the whole point.
Karin's life has always been rough. She's an orphan living with relatives who don't quite want her around, her grades are terrible, and she's genuinely terrible at sports. The only thing she has left from her mother is a ring, and honestly, that's not much to hold onto. Everything changes the night her beloved cat dies. A mysterious boy named Kazune appears at her darkest moment, and strange occurrences begin piling up until Karin realizes the impossible: she's a goddess with actual supernatural powers. The catch is she's not alone. Other young goddesses exist, and they're watching her closely. As Karin stumbles through understanding her newfound abilities, she discovers that being divine comes with real enemies and genuine danger. She'll need to figure out who she actually is while learning to control powers that keep growing stronger. What starts as a lonely girl finding purpose transforms into something bigger, stranger, and far more complicated than she ever expected.
