Mir is by far the most difficult Reyvateil in the are to approach mainly because of her decades of mistrust towards humans. However, if enough trust can be obtained to Dive with her, she'll eventually agree to being tied up (although surviving the Dive is often another matter entirely). Her outfit perfectly highlights her best feature and weak spot: her butt, but the hips and backs of her thighs are good targets too. Never try to go too far with her though, as she's also the only Reyvateil who can effectively fight and escape without relying entirely on Song Magic. Once full trust with her is achieved, she actually proves to like leather restraints and gags, surprisingly enough.
