As the poster child for the Rank-S tsundere, Rin is a very desirable captive for zettai ryouiki fans, but her magic and martial arts skills make her very difficult to capture by force. She will agree to be tied by those who can bring out her dere side, often just by being nice to her and proving to be someone who she can rely on without getting in her way. When it comes to her tie and outfit, there's no need to change a thing and maintain focus on her exposed thighs and hips, as her inner thighs are her weak spots with her reaction to the touch being determined by which side of her personality she's showing. Give her a heavy gag tied either over or under her hair while emphasizing her eyes. Try not to cover too much of her face though as bringing out her dere side brings the bonus of seeing her rare blush.
