Setsuna is all about business, so she isn't one who will give herself up very easily for being kidnapped when she's working, but she might be convinced during her downtime if she can't be taken by force. It can be difficult to decide on putting her in a tie that focuses on her hair or her legs, and there are options to be able to focus on both, but she actually looks very nice in ties that show off as much of her body as possible so be sure to poletie her or tie her in some way that doesn't let her scrunch herself up. Any kind of gag works well for her, but always stick with one that can be tied under her hair, as stroking it is her favorite thing.
