^ Actually, I think the zanpakutÅ are more similar to the
Zodiac weapons, because they are sentient (to be sure, I now recall that the more advanced versions of zanpukuto also had distinct souls; so, my apologies, you're not that far off-target).
In my opinion, a better anime analogy for the Anima weapons would be the demon weapons of
Soul Eater. The weapons in that manga/anime series were literally characters in their own right, each of them paired with a particular user. For example, the lead character
Maka Albarn is paired with her scythe,
Black Star.
