Sky High AU, Elsa Ice, Anna Berserker
"Uh, hello?" Elsa was only a first year. Elsa really couldn't deal with a villain. Elsa'd heard the horror stories of students getting assassinated, so, very cautiously she approached the dark figure the sound had emanated from.
A neighbor's light switched on and Elsa jumped back. Flames jumped at her, no, red hair, she realized as the weight toppled her over. She braced herself and thought cold thoughts.
The ground below her prickled, ice formed, insects fled, and her eyes turned deep, deep blue. They pierced through the fire burning in the eyes of the figure above her and as she prepared herself to call up a blizzard the figure blinked. The fire inside of her died and only confusion remained.
"Who're you?" The girl asked from atop Elsa.
Elsa froze. The demon that jumped her was gone; only a child, no older than 12, remained. The ice inside her subsided and she replied, "I'm Elsa, I live here."
The girl blinked again, looked up, looked around, looked back down, and fear flooded her system. "Shit, shit, not again, what the hell is happening?" She lurched off of Elsa and stared down at her ripped clothes in dismay.
"What?" Elsa was beginning to put the pieces together, "can you remember anything?"
"I-I, I'm Anna, my name is Anna."
