Nishi would write a few Synth-metal albums and probably play the instruments herself, along with one work of baroque chamber music and maybe a neo-romantic symphony if she gets bored.
I can see her also working on a book of beat poetry politicising the class divisions in Kusari. It'll probably contain highly irregular metres and regular innuendo, and a few unofficial neuralnet user's guides on how to change the droptanks on a Blossom. She would never write an autobiography of herself, and would certainly rather blow her own brains out than write one - she's a terrorist; she doesn't want to immortalise herself.
