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 after joining a literature club. She ended up being responsible for three 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 *

You are now in college and Toga followed you. You were trying to tell her to leave you alone when you walked straight into Monika. Before you could say anything about the sudden reappearance in your life you heard a scuttle behind you and turned just in time to see Toga throw Ayano to the ground. Finally as if the shit show wasn't complete Mita appears behind you too.
