Kaori knows how to be aloof to those who she doesn't really care for, but it's better to take the time to get to know her since she isn't as much of an ice queen as some people may think. This is also safer than trying to take her by force since she knows how to punch and punch hard. Her school uniform allows for a skirt-hiking shibari to expose a view of her thighs, but taking the easy road means missing out on her nice chest while her sides comprise her weak spots. For her gag, use one that won't get caught in her hair and emphasizes her eyes. Whether or not she resists much will depend on how well she's treated.
