It's a book that awakens to new fetishism.
A collection of new fetish-specialized works that stick to the gap between the cute and refreshing atmosphere of sailor clothes and the navel that you can see for a moment. At first glance, it is a collection of illustrations of cute girls, but in fact, you can see the navel. Even if you didn't feel anything at first, your eyes will soon be drawn when you notice. I hope you will notice the magical power of such navel.
