Pussy Galore, Octopussy and Plenty O'Toole are nicknames, codenames or nom de guerres... In the case of Plenty O'Toole the surname can actually be O'Toole since it is a normal surname nonetheless "Plenty O'Toole" can be understood as "Plenty tools" where "tool" can be there as part of the semantic part of the pseudonym, however in Kissy Suzuki there is no such pairing; Kissy and Suzuki aren't a meaningful combination... Mirfak's hypothesis that Kissy is derived from Kesiah (which means cassia) is a slightly superior possibility, yet as an African name it makes no sense in a full-bloodied Japanese woman... I guess rather than asking this among onomastic fans I should ask it among literature analysts with an expertise in
Ian Fleming... If there are any...
