"Usagi" mean "rabbit," and Usagi Yojimbo is basically a wandering-ronin graphic novel series in which all the characters are animals. It's a lot of fun--I haven't read all of them, but several. (Actually, yeah, checking out the website, I realize I probably have like a decade of catching up to do...)

Anyway, the Zatoichi character was a boar who had lost the ability to smell--the equivalent, for a boar, of being blind.

Thanks for the songs! I especially love the first.
