The story of Kate also owes a nod to the film noir classic, D.O.A. (1949) and the remake, D.O.A. (1988). In both, a man is poisoned, and he searches for his killer in the time he has left.
Ani tells Kate she looks like the Terminator bitch with her sunglasses. Later, when she takes her glasses off at the beginning of the final assault, her left eye is red, as is the left side of her face, a clear nod to the legendary killer.
The TV show Jojima is watching is a Sci-Fi movie/series know as Uchu kara no messeji: Ginga taisen (1978) from the late 70s.
The soft drink that Kate is looking for, "Boom Boom Lemon", is fictional.
