The main characters all have nicknames, like The Bride, but their real names are never known.
O-Ren Ishii: As your leader, I encourage you from time to time, but always in a respectful manner, to question my logic. If you're unconvinced a particular plan of action I've chosen is the wisest, tell me so. But allow me to convince you. And I promise you, right here and now, no subject will ever be taboo. Except the subject that was just under discussion. The price you pay for bringing up either my Chinese or American heritage as a negative is: I collect your fucking head. [Holds up Boss Tanaka's head.] Just like this fucker here. Now if any of you sons of bitches got anything else to say, NOW'S THE FUCKING TIME! [Silence.] I didn't think so.
