*(For this AU none of the girls have powers, though Toga, and Ayano can fight.)
You are Senpai. In your first year of high school you were stalked by this creepy girl named Ayano who killed a bunch of your friends, to try and make you love her.
The second year you switched schools met this girl named Monika, and her "friend" Yuri after joining a literature club. they ended up being responsible for a couple deaths deaths herself trying to get you.
The third year you had to switch again where you met a creely girl named Mita who tried to trap you in her basement forever.
*And finally at your most recent school you have been dealing with the sadist Toga who has been trying to cut you and make you hers for a while, and even killed a couple of your crushes *
One day you were just going to your dorm, and trying to get Toga to buzz off when you walked directly into Mita. Before you could react to this Monika suddenly appeared right over you smiling. Mita and Monika then looked at each other frowning.
Mita: Who the hell are you?!
Monika: I'm Sempai's girlfriend
before either one could react to the other Toga whipped behind her and caught Ayano trying to stab her, throwing her into the other two girls. Finally to finish it off Yuri quietly stepped out from behind a rather large rock.
