I haven't, but I can guess.
It's either
She's already dead, and is in fact the lost soul herself, OR she's taken major brain damage, and is wondering out of her actual body, OR she and her girlfriends from the flashback are ALL dead, and it's some sort of contrived plot twist involving all three, probably composed of either possession or a three-soul construct,

Anyway, Kanon really got on my nerves, frankly. I like peppy, "I can do it!" attitudes as much as the next guy, but her apparent fetish for tazing people really irked me.
I LIKE Keima. AND his PFP. Put the fucking tazers away, damnit.
Still, gotta love Keima's reactions to Kanon's concerts.
Kanon: This is me, singing!
Keima: This is me, not giving a shit.
