After finally managing to help her with her own parents they still have to face their biggest challenge.

This time, it's all or nothing. The girls will have to use all the aces they have up their sleeves to make sure things end the right way. It's about their own father after all. And as if things weren't hard enough, Eri, the porn star born in Marakoma will also need their help: someone wants her career to be over and due to the circumstances, the sisters are the only ones who can help her.​
