Onii-chan no Koto ga Suki Sugite Nyan Nyan Shitai Burakon Imouto dakedo Sunao ni Narenai no

Saya is an average school girl in every way but one: she's got a HUGE crush on her older brother! She's never been able to raise any flags with him (mostly due to her habit of beating him to a pulp whenever she sees him), but one day, she wakes up in the body of a cat that he brought home! Could this be her chance to make her beloved older brother fall for her?
