That's exactly the point. Tearing himself apart inside until there's so little left of him, anything can be done with the remains..... That's what they're in the business of, here, with the less cooperative slaves. Those who give up easily, those who are willing to submit..... They find themselves with easier lives, even relatively comfortable ones. Some people, after all, simply wish for things like dedicated bodyguards, or guaranteed servants. Some of them will be poised and appropriate for exactly such missions, and go on to lead actually decent lives with kind, thoughtful masters who may even grow to care about them as people in their own right.

Kanji, however, will never be one of those fortunate few. He's too late to understand the use of bending, rather than breaking, or graciously accepting and improving his lot in more subtle ways.

Vexen works on dressing Kanji the rest of the way, now, manipulating his limbs methodically to slot them into the dress, even lifting him at one point, effortlessly, to get him into it fully. The whole process has been undeniably gentle, but it's obvious he's strong, if he can lift him so easily--strong enough to break such a fragile form without a second thought, if he so chooses. Sliding arms into puffy sleeves, arranging the heavy skirts, lacing up the back, slipping the high heels onto stocking-clad feet..... At least he doesn't bother with jewelry. The outfit is more than enough.

No, now that the work is finished, Vexen goes to fetch a mirror instead, wheeling it over to stand before Kanji's chair. He solicitously lifts Kanji up so he can see everything fully--and so Kanji might be able to stand, if he can figure out how to get his feet under him and support his own weight. "There you are. All cleaned up, and ready to be put back on show, just as promised."
