With the recent explanation of Zaraki's Zanpakuto, Nozarashi, we learn that he did not have a constant release Zanpakuto, which is obvious. Byakuya then goes on to question the very existence of a constant release zanpakuto, but that doesn't make sense. If Ichigo has Zangetsu, then obviously a constant release Zanpakuto exists. What are your thoughts on this?
