B.B. Kiddo is the daughter of Beatrix Kiddo. Throughout the entire first volume, it is thought that B.B. had died when the Bride was attacked and left for dead on her wedding day. We later find out that B.B. is alive and well and in the care of her father, Bill.

Beatrix goes to Bill's house, the last person on her death list, only to find out that B.B. is still alive. Bill gives them the chance to meet each other by letting them watch a movie together until B.B. falls asleep. Once B.B. is asleep, Beatrix goes downstairs to finish her "unfinished business" with Bill once and for all.

Beatrix ends up killing Bill and taking B.B. away with her in the middle of the night to start over.
