A tale of saucy erotic incest that begins with siblings at each other's throats. Does that sound hawt or what?

What kind of little sister is YOUR little sister?
Depending on the present you give her, Chie's looks and personality will change with every play through.
There is certainly an "imouto" JUST FOR YOU, right here.

Her looks and personality are properly reflected in the story, CG, and of course... the erotic scenes!!
There are 9 different little sisters that can occur via the " ORE NO IMOUTO SYSTEM "

Our little sister loving staff placed a high level of emphasis on the theme of:
"You cannot choose your family."
