Does anyone know how to make the books work. I only have 2 skills and no matter how many books I use it keeps saying the book is out of content or I can't learn anything from this book.
Train with Yoru multiple times to get 3rd skill
I think it's random, and depends what book, I think magic book you can never learn it's hentai book you can and learning book, if I'm not mistaken
You give the books to the girls they learn different abilities
