"Please....Please forgive my betrayal"- Sofie to Bill
Sofie Fatale is O-Ren Ishii's lawyer, second-in-command, and best friend. She is of mixed Japanese and French descent and serves as O-Ren's interpreter whenever she speaks English to her Japanese subordinates, using her proficiency in English and Japanese. Although she is referred to as a protege of Bill's, she does not display any martial arts skills during her appearances.
The Two Pines MassacreEdit
Sofie was present at the Massacre at Two Pines. She arrived after the members of the Deadly Viper Assassination Squad nearly killed Beatrix Kiddo to see how O-Ren was doing and if the job was completed. The Bride saw Sofie talking to one of her associates on her cell phone before she was shot by Bill.
After the massacre, Sofie continued to work with O-Ren in Japan and remained in contact with the other members of the Deadly Vipers Assassination Squad. She was a loyal asset to O-Ren and Bill.
House of Blue Leaves MassacreEdit
Four years after the massacre at Two Pines, Sofie Fatale was present at the "House of Blue Leaves" when The Bride arrives to kill O-Ren Ishii. The Bride is in the restroom when Sofie walks in and answers her phone; the ringtone (a monotone version of "Auld Lang Syne") is recognized by The Bride. She recognized Sofie, as she was present during the El Paso massacre along with the codenamed Vipers, though did not assist in beating her. Instead, she had seen her talking to somebody via cellphone before Bill shot her in the head. Beatrix Kiddo captures Sofie and brings her to O-Ren Ishii. The Bride then cuts off Sofie's left arm as a means of both enacting revenge on her and showing O-Ren her intentions for a duel.
After defeating the Crazy 88 and killing O-Ren, the Bride took Sofie into the back of a car. She told Sofie that she's sparing her life for two reasons, with the first being information. Originally Sofie told her to burn in Hell and refused to tell her anything, but that quickly changed when the Bride threatened to cut off a body part every time she didn't get the information she wanted, and that they would be things Sofie would miss.
After the interrogation, the Bride reminded Sofie that she could keep her "wicked life" for 2 reasons, and the second was so that Bill, through Sofie's deformed body, could witness the extent of her mercy. She wanted Sofie to tell him all that happened that night and everything she told the Bride, and that the Bride wanted him to know. She also wanted all the Vipers to know that they would all soon be "as dead as O-Ren."
Reunited with BillEdit
After that, the Bride drove the car to a nearby hill and pushed Sofie's body down it to a hospital, where personnel rushed to her aid. Bill came and visited a saddened, and clearly traumatized, Sofie. Sofie first begged Bill for forgiveness over her betrayal. Bill showed her sympathy, saying that his heart ached over what the Bride did to her. After talking about what happened, Bill asked Sofie if the Bride was aware that her daughter was still alive, which she wasn't at the time.
After this, it is unknown what happens to her.
- Lingual: Sofie is of mixed Japanese and French descent, and can therefore speak fluently in both languages. She is also fluent in English. She served as O-Ren's interpreter whenever the latter spoke English to her Japanese subordinates.
- Lawyer: Sofie served as O-Ren's lawyer. She seemed to help O-Ren, and possibly other Yakuzas, get out of legal trouble. She could be seen talking to her associates on the phone.
- In the Japanese Unrated version of Kill Bill: Vol. 1, The Bride actually cuts off Sofie's other arm during the interrogation scene in her car after the battle at the House of Blue Leaves. Quentin Tarantino did not add this scene in the final Western cut of the film and her other arm was never amputated and you can see her other remaining arm when the bride rolled her down to the hospital.
- Tarantino announced that he already planned the new volumes in the series, and revealed that Sofie Fatale will inherit O-Ren Ishii's & Bill's amassed fortune's and would raise Vernita Green's daughter Nikkia Bell so she can go after The Bride.
