I've been trying to remember the name of series of oneshots that take place at a school for girls for a few years now. It involves mind break/mind control. When the bell in the clock tower rings all the girls become very slutty. I hope someone knows what I'm talking about. Last I check Little White Butterflies has a black and white version of one of the covers in a recent post but the post itself isn't about the oneshot. I hope someone can reply with the title soon.
