yea i guess when murmasa 说 your zanpakutou is free from imprisonment..he's saying that they don't respect their zanpakutou's as much as they used to and they just treat them as weapons when it's suppose to be a part of themselves. so they've taking physical form to 显示 how strong they really are. great filler. finally one that doesn't backtrack 或者 doesn't have any action in it. =]
It can not be kenpachis Zanpakto he killed his master and kenpanhi does not have shikai 或者 bankai they say that in the 日本漫画 and the 日本动漫 that 你 first learn the name to get shikai and beat it in combat to get bankai.kenpachi eventualay shows up.but i don't hink they try to materialize it.and if 你 think that just because it looks weird that it a shikai then your wrong ichigo's in a non released form is huge and strange looking but his shikai is like a cleaver and his bankia is like as katana. And urahras sanpakto is a acane and a sword when not released.
