Kurara is a bit of a trickster due to her ablity to transform between her child and adult forms, thus allowing her to literally shrink out of any tie she's in when tied up in her adult form. Keeping her from escaping completely requires special rubber bands that expand and constrict to keep her body held no matter how big or small she gets. Use a dangling OTN for her child form and a knotted cleave for her adult form when it comes time for her gag. So long as she's taken off guard, she can be taken without too much trouble.
