As a girl-next-door type, Saori isn't hard to take off guard and by force, but she'll also enjoy it a lot more when approached casually as she does have a thing for bondage. Because of the latter, she'll often be willing to go with naughtier ties so long as they don't go overboard with the materials used. Bind her in a manner to emphasize her chest but also leave her hips and spine accessible. Same thing goes with her gag: Something heavy but not overboard and her hair is short enough to not have to worry if a gag will cover too much of it in the back. Bonus points for capturing her and Sakura Matou together.
