Katen Kyoukatsu is Kyoraku's zanpaktou, but since they can take on a human form, the younger girl hid Nanao's zanpaktou within her all the time because as he stated, she likes to "hide" things. Therefore Nanao's zanpaktou isn't the same as Kyoraku's
WHAT!!!! i thought both swords are personally owned by kyoraku or wait what now what's next??hohoh,, dont tell me the next time i read the next chapter would be like"i do not own these zanpakutous but rather it was your's and your mother" or something like that?
