A magical fairy visits the Sakamaki mansion in hope to find hospitality and kindness, but instead, all she got was rejection and the cold glare. So to punish them, they've been turned into cats until they learn what love is and how to love someone. They've never met other humans other than Yui, who has also been turned into a cat. Their father, not knowing they had been turned into cats, threw the cats out in a box and left them on the streets.
The same fate befalls on the Mukamis, Tsukinamis and Kino. They've all been taken to the streets and their hope slowly disappears, until a black-haired, 17 year old, high school student named Zea takes them into their mansion with her brothers and sisters. Like the Sakamakis, they were rich as well. But unlike the Sakamakis, they loved and took care of each other. Zea was in the middle with three older siblings and three younger siblings.
They all fall in love with her, but what will happen to them when KarlHeinz accuses Zea of kidnapping his sons?
