To be honest its more of an artist license gone wild than anything else, not that I'm saying its bad, teddy bear headed swords man a stroke of genius.
you have to look past the liscencing to see it's true genius! just go read the manga then rewatch the show and you will (hopefully) see what I'm talking about.
