[Death by Mirrors]

Love your current avatar by the way. Psycho goblin school girl on a killing spree.

Oh and recently I've been reading a novel where death by old age is essentially no longer a thing, so there's a reaper profession (more or less, although you can't really apply for it but are chosen as an apprentice by one of the existing folks) that kills people for population control. Everyone else who dies gets revived again, but once you're killed by one of these scythes, you're gone for good. Interesting story.
