As a police officer, Miyuki knows how to defend herself, but isn't able to do very much once she's been fully subdued. Even if using her own cuffs against her is a bit cliche, it's still effective until she can be more heavily secured with ropes or something else. She's a bit too shy to allow herself to be tied when asked, but won't put up much resistance if she's caught by someone she likes. She's got nice legs and is a good target for braid fetishists, but she's rendered entirely helpless when her hips and butt are touched. Use gags that won't catch her braid.
