you're right about zanpakuto's name...but he was the one who determine the true names and the first one to choose all the names of all things in Soul Society...and about Oetsu, i agree he the most important characters in the series all time..i mean if he doesn't exist there is no zanpakuto at all..and one thing is left for shinigami is a merely ordinary katana...
