Katsuragi is one of those girls who prefers to be the dom rather than the sub, so catching her is easier said than done, especially by male captors, but she can actually be fairly-easily distracted by traps using other girls as bait. Because she primarily fights by kicking, heavily restraining her legs is a necessity. Once that's done, any tie that emphasizes her chest and a gag that highlights her long hair are definitely ones to aim for. Once she settles down, she can be a bit of a tease but there will be many times where it's just an act to get her captor to drop their guard. Treat her well and she will eventually drop the ruse, becoming a willing captive in time.
