Thought about this for a while and I think it is Unohana. He could be reviving her. He may have anticipated Kyoraku pitting her against Zaraki, so prepared to revive one of the to Kenpachi's, as the Gotei 13 could use their power. Reasons for Unohana: 1. They were rivals, and he might enjoy the competition. 2. Her wounds *were* repairable.

Plot Reasons 3. She is a powerhouse with abilities yet to be explained in the Manga. 4. Would help ALOT with the survival of the Soul Society. 5. Would shut up alot of fanboys and fangirls. 6. Would be a plot twist that makes sense in the story, but is unexpected enough to have an impact.

Reasons he would have prepared for Zaraki: 1. His Sheer power. 2. He *has* done work for them before, making Zaraki's Eyepatches. 3. Zaraki's power would have made him an 'interesting' study, and we all know how he is when he finds something interesting
