## Description
Our heroine Yuri, who is a rabid yaoi fangirl, is pissed off that she’s not as good looking as her twin brother Kairi. They find a wishing stone and then Yuri picks it up wishing she was a sexy beast…but then she drops the stone and breaks it. About 18 days later, on September 1st she starts her new school life with Kairi, but one morning they find that stone she broke back on top of her bed. When Yuri touches the stone, she and her brother end up switching bodies. While her brother isn’t too happy being a girl, our heroine Yuri can’t wait to spend her time being a bishounen and yaoi it up with some dudes. The body switching seems to be on and off and so the twins’ adventures begin!
