Tahseen dit :

no if a zanpankuto dies the soul aeprer loses thier power (/is sealed), like when they are defeated and the sword breaks, they don’t die. the shinigami is the soil not the seed (if the soil is salted the plant dies).kenpachi’s sword is in shikai because of his intense spiritual preasure, like ichigo, so we have no idea what the hilt of his katana looks like but i asure you that it is the shape of a katana (only shinigami with katana style shikai retain the hilt’s form, this is not true for the sabers, rapiers, spears, ball & chain, or any of the other weapon type, yet all shinigami carry katanas).no zanpankuto is like their user, atleast not at the beginnig of their relationship (this only changes as the shinigami and zanpankuto grow closer together, they become like each other and grow stronger by finding balance) someone like kenpachi would never be like his zanpankuto or vise versa (in fact that is the only thing they would really have incommon from being forced into a relationship niether of them really wants, is their desire to stand apart), kenpachi does become like anyone else, he is stuborn and only follows his own way.kenpachi constantly reminding others to stay out of his way or he’ll kill them, in contrast (an thats the key to identifying a zanpankuto’s shinigami) his zanpankuto wants to gather his brethren to his side even though he shuns the companionship of shinigami.also i have noticed that he is scared, much like kenpachi’s blade, think of the beating he took under kenpachi’s hand without any empathy or appreciation, imagine what that might do to a zanpankuto’s personality.zangetsu emotion is in his words by the way, he like a father to ichigo, because ichigo relies on him in this way with all things shinigami, in his fight he voice reluctance and regret.and yes, they probably do have to beat their zanpankuto back into submission unless somebody defeats muramasa and breaks his bankai’s enchantment, still the opportunity exist for all lot of people without bankai to earn thiers now.oh yeah that’s another reason kenpachi and his zanpankuto would not be alike, they really only start to grow closer once they can manifest (after attaining bankai), before that they dont really speak face to face with thier zanpankuto, and lack this opportunity.however muramasa’s bankai is one keny might actually use despite his distaste for non physical attacks, of course he would have to find someone who made him take off his eyepatch before he would even consider it, and then only as a last resort (basically i feel bad for muramasa even if he is acting like a brat, he shouldn’t have to live under that kind of oppression, it must be like hell for a zanpankuto especially one that probably doesn’t want to fight judging from his power).
