A Slight spoiler for My Little Death Note

So I was reading that story that was featured earlier, Inner Demons (I freaking love and hate ones like that at the same time. Because I'm always worried they're going to have the everypony dies ending). While i was reading it, I suddenly had an idea for My Little Death Note. I won't be giving away how it happens, or why it happens, or even how It's going to work in the story (But I've had this sort of thing planned for quite some time).

Trixie returns!!! And it's as the hero (or is it?).
