お兄ちゃんのことが好きすぎてにゃんにゃんしたいブラコン妹だけど素直になれないの

Saya is an average schoolgirl 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?
