A/N:
Hiya! Welcome to my second AB! project! This is my own version of a prequel - Initial Impulse. I finished Track Zero a while ago, and to be honest, I wasn't too satisfied with it. I liked it, don't get me wrong, but I can't help but feel Maeda-sama could have done more with the story (since the anime is so good and all).
Well, enough babbling ;) Hope you enjoy the story!
Prologue
The two of them stood in the rain, guns aligned perfectly with their respective targets.
They kept the distance between them. Yuri was standing next to an unconscious Noda strewn across the tiled floor, now soiled by the heavy rain. Her eyes narrowed as she thought of the other members of her team stationed in other parts of the school cafeteria. She had no doubt they had suffered the same fate, their 'bodies' now affected by the toxin as they lay unconscious.
On the other side, Iwasawa was standing protectively over Hisako's body, the latter lying soaked in the crimson of her own blood. For the first time in a very long time, Iwasawa couldn't stay the cool and collected character she was. Instead, she was really having trouble quelling the slowly rising, burning rage inside her as she stared down her enemy.
And then, in the darkness of the cafeteria rooftop, a gunshot rang out.
