You Only Live Twice
Kissy Suzuki is an Ama diving girl who is distantly related to one of Tanaka's agents and is therefore asked to assist Bond. In the film, Kissy is an agent working for the head of the Japanese secret service, Tiger Tanaka.
Bond, going undercover as a Japanese fisherman, stays with Kissy and her family in order to better establish his cover. In the film, Bond and Kissy use their cover to investigate a nearby island where the evil organization SPECTRE and its leader, Ernst Stavro Blofeld, occupy a castle where Blofeld maintains a "suicide garden" where people come to die (whether they want to or not). Bond, however, is seeking revenge for the murder of his wife at the conclusion of the previous novel, On Her Majesty's Secret Service. Bond is helped by Kissy to swim to Blofeld's "Castle of Death" where he scales the cliff to infiltrate the fortress.
Bond sustains amnesia in the aftermath of his vendetta against Blofeld and is believed dead by Tiger, Dikko Henderson and his superiors; in reality, he comes to believe he is a fisherman and lives with Kissy for several months. When Bond decides to leave for Vladivostok, Russia, believing the answers to his identity are there, Kissy does not follow; unknown to Bond, she is pregnant with his child. Kissy Suzuki (at least the literary version) remains the only character who bears a child by him (that has been revealed at least).
"Blast From the Past"
Kissy Suzuki appears again in the Bond canon in "Blast From the Past", a short story published in 1996 by Raymond Benson as a direct sequel to You Only Live Twice. By the time of this story, Kissy is now deceased (having succumbed to ovarian cancer a few years before the story's events) and Bond is contacted by his Anglo-Japanese son named James Suzuki (of whom he has evidently learned of in the interim.) Although Bond knew of the birth of his son early on; he has not apparently paid much attention to his duties as a father; save for paying for the tuition and expenses when his son was a college undergraduate. This is one of the few cases in the Bond universe where a character is stated to have died naturally, in Kissy's case due to cancer.
