Follow her.

Someone else having your abilities is odd. It was obvious they wouldn't be exclusive to just you, but nobody else in this school had been using them before now. Running down the hallway, there's a faint shape turning a corner and no time to think about it before pursuing it. As soon as you turn the corner, she's already moving down the stairs in a hurried pace.

There isn't time to hesitate in running behind her before both of you are in front of the entrance. She clearly isn't interested in talking and if she's moving this far away from you, she must know exactly what you're suspicious about. She needs to be stopped.

Never having used the ability before other than minor uses for cooling drinks or making ice cubes, the confidence you have in using your ice powers, isn't great. Your hand forms a blue mist like substance before cupping it and throwing it across the air, as it begins to harden into an stream of ice. It speeds behind her head and smacks the doors, causing ice to spray and freeze them shut.

"Hey. Got a moment?" The question is with the same practiced gentle smile.

She doesn't even seem that worried as she calmly turns around and pushes up her glasses. "....if you do that....then I will have to do this."

She takes one hand off her glasses as her hand begins to envelop in a red glow, with smoke brimming around the fingers. She throws her hand forward, releasing an orange ball of flame that grazes you on the leg. It doesn't hurt that bad but from how composed she seems, it's possible she's adjusted to fighting Akirakana Kuron program users.

This could go either way.
