Even more convinced that Zaraki - Unohana's sword she abandoned - hence paralels with asauchi dilemma
havent been keeping up with all the theories flying around, but that thought also just occurred to me. Maybe he is a/her zanpakutou, ergo the awesome reiatsu (consider how strong she is), the inability to wilffully release shikai, bankai or revert to its original state (for the uninformed, just like ichigo, zaraki's zanpakutou is permanently in released state, he doesn't know the name, his power is just that strong). They've obviously fought in the past, and they've wounded eachother. Waiting to find out what that implies, besides the fact they want to make sweet sweet love down by the fireside. And by love i mean alloutbrawl.
Also zaraki isnt that weak. Unohana even told him off for not using both hands. WE saw how much stronger he was, so much so that he destroyed Nnoitra in one swing, and yamaji decided to not train him anymore after that one lesson. Just wait till he uses both hands. Should be interesting.
