Never got to watch the anime itself but saw a short 2-minute clip on a profile on Facebook like 8 years back, and never got to follow up on it.
From what I remember:
- It's about a girl who tortures people in her home.
- I remember a scene where this girl almost escapes with a knife, tries to get out the door but is cornered and gets tazed.
- She jams her own head into the knife, exclaiming that she won't allow the girl to be the one to kill her.
Pretty gruesome, I know, but I've wanted to watch it for over a year and just can't find out what it is...
