Recently, a new student transferred at your school - and she's quite.. odd. Akemi Homura. Cold and reserved student that seems to pander towards specifically one of your friends, Kaname Madoka. You've shrugged her off as best as you could, but ultimately failed.
Today, while you were walking home, you suddenly felt oddly sad and empty. Grief filled you as everything around you got oddly distorted and weird, until you weren't on the street anymore. You were in some kind of alternate reality, and at the centre of it all, stood a large being lunging towards you.
Terrified, you dodged its attacks as best as you could; before you knew it, you dropped to the ground, injured. Out of all the people in the world, you didn't expect to see Akemi Homura come to battle that being.
