I speak, of the perversion done to this council...which I love...more than my own children...BY MAKING A CHINESE JAP-AMERICAN HALF BREED BITCH ITS LEADER!

—Boss Tanaka before he was executed by O-Ren Ishii

Boss Tanaka was one of the members of the Crime Council. However, on the night O-Ren Ishii assumed power over the Tokyo Underworld, Boss Tanaka used the term 'Chinese Jap-American' as a negative and as punishment for insulting O-Ren's heritage, was decapitated with O-Ren telling her associates that if they brought up her heritage as a negative, then she would execute them.
