Your walking down a sketchy alley, phone in hand. Then you accidentally run into someone.

"Hey, are you okay Kanade?" You hear three female voices, Mafuyu, Ena, and Mizuki say at the same time. You look and see a fourth girl, Kanade, who's getting on her feet from the other three.

You get back up and you see a hand outstretched to you with your phone in hand. "Hey, you dropped this. Names Mizuki, what's yours" They have a smirk on their face.
