I feel like the narrator is Kayo's mum and she used the Swap Technique to enter the scissors and fake her suicide or something. And Elluka referencing back to Sati and Lukana is another hint at Kayo and TotallyNotGakusha?
(Spoiler warning) You've got it right, Gallerian. There's info on the TVTropes page for the novel if that's what you're after.
Nice! I hadn't thought to check there, thanks for the tip.
