Yukari is a very easy catch in the sense that she can be taken by force or coaxed into being tied willingly. The hard part with the former is watching out for her best friend/bodyguard and, in both situations, catching her while she's sober. She is worth the trouble though as she makes for a very sexy captive and binding her in any position that emphasizes her weak spot, her legs, works for the best. Binding materials and gag don't really matter too, given how kinky she is (and openly shows for her students) so don't be afraid to break out the leather, latex, ballgags or hoods for her; she wants the attention.
